https://soundcloud.com/user-807100315/hostinger-best-web-hosting-review Visit at- https://webhostingservice.home.blog/2019/06/02/hostinger-free/ There's no uncertainty that with regards to web hosting, Hostinger is just the least expensive choice accessible today, with costs beginning at $0.99 every month. No other organization figures out how to try and approach. A large portion of them offer a fundamental arrangement for multiple times the cost. Believing that it's unrealistic? It isn't. Yet, let me let you in on a little mystery at this moment. To get the best costs, you'll need to focus on Hostinger for quite a while. This would be a keen activity – if the administration is really extraordinary. Since your guests couldn't think less about the amount you pay for hosting. They do think about quick stacking speeds, and about really having the option to arrive at your site when they have to. They additionally need to realize that their own information will be secure and ensured. Could Hostinger offer that? I have my assessments; however I would not like to put together my audit with respect to my supposition alone. As Website Planet is accessible in various dialects, for some odd reason we have web hosting specialists dissipated everywhere on over the world. This was my brilliant chance to play out an enormous scope test, and I chose to do precisely that. We had 30 specialists join to Hostinger and dispatch a neighborhood form of our testing website in 30 distinct nations. They messed with each accessible element, observed stacking velocities and execution, and even besieged client care with questions. They contrasted the outcomes and other mainstream has, as SiteGround and InterServer. This speedy response to every one of our inquiries is that Hostinger performed strikingly well. In certain nations, similar to Russia, it came in at #4. In others, similar to Israel, Hostinger grabbed the #1 place. Peruse on for the long answer. I've point by point my full close to home involvement in Hostinger, and I'll disclose precisely how to take advantage of what the organization offers. To perceive how Hostinger looks at to different administrations, look at our rundown of the top web has. Everything an Amateur Needs With costs being as low as they may be, my restless character quickly recognized two zones where Hostinger may be attempting to pull one over on me: highlights and execution. Indeed, I'd love to pay half of what the contenders charge, yet I would prefer not to get just 50% of what they give. Fortunately, that wasn't the situation by any means, as Hostinger's arrangements incorporate all that I expected to get moving, from abundant assets to execution boosting apparatuses. Three shared hosting plans are accessible – Single, Premium, and Business. Each of the three works on head of Hostinger's own special control board, cPanel, which incorporates simple auto establishments of WordPress and many other substances the executive’s frameworks (CMS). I pursued the essential arrangement, which accompanied 10GB of plate space, 100GB of transfer speed, 1 email record, and backing for a solitary website. It's sufficient assets to construct an entirely good website – consider hundreds pages and a huge number of HD pictures. Certainly enough to grandstand your composition, innovativeness, items, administrations, or whatever you're anticipating hosting. The two progressed plans accompany boundless data transmission, boundless email accounts, and boundless websites. Some additional advantages that you won't get with the Single arrangement incorporate SSH access for you Linux-sharp designers, boundless sub domains, and boundless information bases. Programmed every day reinforcements are the one basic component that the fundamental arrangement needs, which means you'll need to perform reinforcements physically or buy the administration as a different extra. Hostinger has an intuitive website manufacturer by the name of Zyro, however it isn't accessible as a component of the hosting plans. Before we dive further into Hostinger's best highlights, a word on the VPS and cloud plans. Hostinger is above all else a mutual hosting supplier. Try not to be that person who goes to the best pizza joint around and requests pasta. There are has that represent considerable authority in VPS and cloud administrations – Fluid Web and Kinsta, for instance – and keeping in mind that Hostinger's contributions in the field aren't the most exceedingly terrible, there's no motivation to go for them. cPanel Has All the Fundamental Highlights, yet Does not have Some Serious Ones As I said previously, Hostinger has built up its own exclusive control board, which means you won't get the chance to play with the dearest cPanel that you know and love. What's that? You don't create enthusiastic connections to hosting control boards? All things considered, you're the bizarre one. At any rate, while cPanel used to be the standard control board you'd get with most has (counting Hostinger), things change. Because of some exhausting venture show that happened some time back, has have been exchanging boards left and right. cPanel is Hostinger's endeavor into the board world, and you'll see it furnished with all the treats you need. From simple auto establishments and DNS zones setups to email accounts, a record administrator, and MySQL information bases, it's all fundamentally the same as what cPanel offers. However, a few things are unique. For instance, auto establishments in cPanel are finished with Softaculous, which additionally lets you clone your site, set up an arranging variant, and even design a reinforcement plan. cPanel's Auto Installer works admirably at auto-introducing WordPress, yet does not have these valuable additional items. Progressed email highlights, such as mailing records, channels, and routings, are additionally absent from cPanel. Did I ever really use them myself when they were accessible to me? Truly, never. I don't know who does. Yet, that is cPanel for you – it probably won't be equipped for everything, except it's certainly enough for most clients. Amazing Reserving On account of the LiteSpeed Web Worker LiteSpeed isn't the physical metal worker, however the web worker innovation that Hostinger employments. It reliably positions as one of the quickest and most dependable web workers, beating the more seasoned Apache innovation that hosts like GoDaddy despite everything use. You won't need to successfully arrange it. Simply kick back and appreciate the first class execution it conveys, particularly for WordPress websites. What you can do, and assuredly ought to do, is initiate LiteSpeed's reserving capacity, known as LSCache. Sounds excessively specialized? Indeed, turning on the Programmed Store alternative basically summarizes it. Stored duplicates of your pages will be made, fundamentally slicing conveyance times to guests. Static pages, similar to business pages and portfolios, will profit by this significantly more. A SSL Declaration that you could conceivably be getting You need a SSL testament. Regardless of what you think and regardless of what anyone might've let you know – you need a SSL. Why? Since without a SSL authentication to scramble and secure your guests' information, the numerous wrongs prowling on the web will seek it. You'll not exclusively be taking a chance with your undertaking and your guests' wellbeing; however you'll additionally endure a shot on Google's rankings. Today, Hostinger furnishes a SSL with the entirety of its arrangements. In the metaphorical yesterday, which for my situation was only two or three months back, no testament was given. What will happen tomorrow is impossible to say. Hostinger regularly messes with its arrangement highlights, and I propose that you triple-check and ensure that a SSL is to be sure included with your arrangement. Realize that if a SSL is excluded, it's conceivable to buy one as a different extra. In any case, that shouldn't be the situation. All that Is All around Structured, however you’ll be under Consistent Assault from up sell Pop-Ups. Laying it out plainly, Hostinger's client experience specialists have designed an awesome interface and client venture, from information exchange to utilizing and dealing with your hosting. Thing is, Hostinger's business methodology depends on continually pushing you to overhaul and buy additional items. It's irritating, best case scenario, and confounding at the very least. Yet at the same time, the plans are unmistakably spread out, and all Hostinger requests on information exchange is your name, an email address, and a secret word. Yahoo for getting rid of all the insignificant data that different hosts are so enthused about gathering. Interfacing a Domain and Introducing WordPress In the wake of buying my arrangement, the time had come to associate a domain and introduce WordPress. I was given the choice to consequently introduce WordPress as a major aspect of the information exchange measure, however I decided to do it the normal way, utilizing the control board itself, to check how Hostinger's apparatuses contrast with what different hosts give. Presently, my domain was really included with the expectation of complimentary when I bought the Single arrangement, which means it was at that point associated with the hosting. Today, for reasons unknown, just the serious plans accompany a free domain. In the event that you wind up getting your domain name from another supplier, interfacing it is simple. Nameserver data is promptly accessible at the head of your hosting subtleties page, and you should simply duplicate glue them into your domain board. Shouldn't something be said about WordPress? I opened the Auto Installer instrument, picked WordPress as my CMS of decision, and entered the essential website subtleties. It was much easier than how Softaculous gets things done, and my new website was ready for action inside one moment. Dealing with Your Hosting with hPanel Is Simple We've secured the way toward getting your website on the web, however starting here on you'll despite everything use cPanel to make alters and changes to your hosting. Setting up an email account, running manual reinforcements, dealing with the information bases, and the sky is the limit from there, are largely possible through cPanel. How can everything contrast with getting things done with cPanel? Indeed, as I would like to think, it's out and out simpler. hPanel symbols are greater and better sorted out, the interface isn't as jumbled with additional alternatives that you'll never utilize, and the combination with Hostinger's different administrations (uphold, buying additional items, seeing charging) is consistent. All in all, would we be able to consider it an ideal usability experience? Actually no, not so much. The explanation, as I said previously, is that periodically your work process will be harmed by up sell pop-ups. Think rolling out a basic improvement to your DNS records, just to be welcomed with this: I didn't "Increase present expectations." I didn't really do anything aside from sign in. Yet, Hostinger is enthusiastic about pushing plan redesigns, and you'll need to consistently be set up to close down these endeavors, of which there are many. Don't count on the possibility that these pop-ups imply that you've by one way or another spent your assets and need to redesign. Pass on, It's the Quickest Common Hosting Administration We Tried Speed and uptime that is what I'm searching for. Tragically, shared hosting administrations will in general vacillate in these regions, no doubt. The explanation is that as the name infers, you're offering assets to numerous different clients and their websites – in some cases up to many others. It takes an extraordinary host to adjust everything and stay away from a bottleneck circumstance where everything's moderate and no one's cheerful. I'm extremely glad to report that Hostinger exceeded expectations in the presentation tests, yet it really surpassed each other shared host that we tried, including the top-level SiteGround, FastComet, and InMotion Hosting. The main two has that improved, and just barely, were the superior Fluid Web (Nexcess) and Kinsta. Incidentally, they can cost around 20 fold the amount of as Hostinger. Just to give you a thought of Hostinger's capacities, the normal stacking season of my completely fledged greeting page was an exceptional 1.56s, and uptime over a couple of long stretches of testing was as much as 99.99%, precisely as guaranteed. I'm going to nerd out and clarify the testing technique and the outcomes in detail, yet on the off chance that you needn't bother with all the specialized data, don't hesitate to avoid ahead to my encounters with Hostinger's help. I'll simply say it again – Hostinger's presentation shook. As I do with all hosts I test, I stretched out Hostinger the chance to streamline my website and make it quicker. This is something you can (and should) do too – simply approach uphold for help. The operator prompted that I update WordPress and PHP to their most recent forms, and introduce a couple of regular enhancement modules. I actualized the exhortation, and continued with testing. The testing itself was finished utilizing three apparatuses: GTmetrix Genius, the Sucuri Burden Time Analyzer, and Uptime Robot's Professional arrangement. The Dallas, TX, GTmetrix worker was utilized to quantify speed and advancement scores in the US. Sucuri was utilized for worldwide execution experiences, and Uptime Robot – who could have imagined – for following the website's uptime and accessibility online in rates. GTmetrix I ran various GTmetrix tests over a couple of months, totaled the outcomes, and determined the best, slowest, and normal paces. Hostinger indicated a promising normal stacking season of 1.56s. The best recorded time was 1.0s, and the slowest one was 1.9s. Not exclusively is the slowest stacking time well underneath the 3s imprint (where the majority of your guests will likely escape), however the normal scores demonstrate that Hostinger is as solid as anyone might imagine. You can see that score-wise, we're getting twofold Bs. That is totally satisfactory, yet in addition probably the most noteworthy score I found in my tests. The main thing left to do so as to get full scores is to improve the pictures further. Sucuri Burden Time Analyzer As with GTmetrix, I ran Sucuri tests on numerous occasions. Sucuri gives you the stacking speed results for some worldwide areas, and I determined the midpoints of the quickest area (which was obviously in the US, near my server farm), the slowest area (Bangalore, India – the opposite side of the world), and the worldwide normal. The normal for the quickest area was an incredible 0.177s, while even in old fashioned Bangalore the normal was good – 1.11s. The worldwide normal was 0.499s, which earned my website an A worldwide position. Frankly? I was shocked by these numbers. A worldwide normal of 0.499s is unfathomable for a common host, and everything I did to "streamline" my site was introduce a couple modules. There wasn't so much as a CDN (Content Conveyance System) dynamic. That is LiteSpeed and LSCache for you, women and respectable men. Get it while it's hot. Uptime Robot What great are quick speeds if your website has low accessibility? Nothing but bad. Fortunately, Hostinger is keeping it tight with practically immaculate uptime – 99.997% in the course of recent months. I'm proceeding to track and update the outcomes; however coming barely short of 100% is actually what I request from my host. Uptime ensure shrewd, the circumstance is somewhat extraordinary. There's apparently a 99.99% uptime ensure gave, yet Hostinger has a genuine scrappy lawful clarification of when and how you can get your cash back. It generally seems like "never" to me, and regardless of whether you some way or another fit the bill for a cash back (as exclusively dictated by them), it's a measly 5% of your month to month cost. Goodness, and it's only for store credit. In any case, beside this assurance issue, Hostinger truly blows it out of the recreation center in the exhibition test. When Extraordinary, Presently… Requires Tolerance As a long-term client of Hostinger, I've had the delight of testing it over and over… and once more. One of my preferred pieces of the administration used to be the help. There wasn't (and still isn't) any telephone uphold accessible, yet stunning, was live talk a successful method of finding support. Day in and day out help, kept an eye on by experts, and supported by a broad information base of immense extents. The main issue? While the operators used to react in a flash, today they take around 40 minutes to hit you up. In some cases live talk isn't even accessible, and you're moved to some ticket/email framework which I've had next to no karma with. I'll be totally fair with you about what this implies: it will be you and the information base. You can't rely on having an hour accessible to just stick around, and in any event, when the operators do reply, that is only the start of the cycle. With 3 brief reaction times in the middle of messages, posing some straightforward inquiries can expand into a whole workday. The Least expensive Long haul Costs Available, by a wide margin Truly, people, this is the explanation you understand this. While going over the many hosting choices accessible today, Hostinger's costs stick out. That is to say, $0.99 every month? That is excessively modest. What's the trick? Straightforward. Hostinger needs you to pursue a significant stretch of time, and it will give you motivating forces to do as such. Four installment periods are accessible: month to month, yearly, bi-yearly, and quadrennial. That final word implies four years, and it's scarcely utilized in light of the fact that practically no other host approaches you to pursue that long. Fortunately pursuing four years will net you what's without a doubt the best cost in the market for shared hosting. Different hosts charge a comparable cost for a yearly arrangement. Crunch the numbers yourself. What's the circumstance when pursuing shorter periods? All things considered, bi-yearly and yearly plans aren't costly, yet they're significantly more in accordance with the market normal. Month to month plans accompany an arrangement expense and don't bode well. Worth insightful, up to a SSL is incorporated (check!), the plans are totally comparable to the business standard. There's additionally a 30-day unconditional promise, so you'll have adequate opportunity to test the administration yourself and check whether it's a solid match. One thing to see during the checkout cycle is that there are a couple of discretionary extra administrations. Fortunately, none of them come pre-checked. I suggest that you skip them all. You can generally include them later at a similar cost, or "convince" a help operator to give you a superior arrangement… dangers of leaving the administration can do something amazing here. Searching for a free domain? Now and again it's remembered for the plans; some of the time it isn't. The serious plans normally accompany one when pursuing a year or more. At the point when I joined, a domain was additionally remembered for the fundamental arrangement. Presently it isn't – go figure. Concerning making installments, notwithstanding the normal charge card and PayPal choices, you'll additionally have the option to pay with bitcoin and different cryptographic forms of money. Whatever your reasons are for needing to have a website secretly, crypto is the best approach to do as such. Hostinger's reasonable shared hosting plans merit your time, your cash, and your thought. Execution has been shockingly extraordinary, and keeping in mind that it's not the most element pressed contribution around, it has all that you truly need. Would it be advisable for you to put it all on the line? In case you're constructing a blog, a business page, an individual task, or a comparative little to-medium website, my answer is a resonating yes. In the event that it's a web based business store you're hoping to fabricate, or a mind boggling administration like an online course gateway, you'll need something more remarkable than shared hosting. It'll cost you, yet Fluid Web and Kinsta are both better prepared for such ventures.
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
Happy Halloween! Audit Statuses of Canadian Cryptocurrency Exchanges
Halloween is a wonderful time of year! Businesses and consumers alike dress up, children go door to door naively asking strangers for candy, and everyone parties celebrating things like death and evil. In the spirit of Halloween storytelling, let me tell you a scary story. There once was a Canadian cryptocurrency exchange. It had one of the simplest user interfaces, the CEO was well known in person and trusted throughout the country for over half a decade, and it had several deposit and withdrawal methods. It was the first to register as a money services business and for much of its history, it was one of the most legally compliant exchanges. It even looked to be headed for public listing on the TSX. The exchange operated for 6 years, assuring users that all funds “are stored in cold storage, using some of the most secure cryptographic procedures possible.” Unfortunately, while we celebrate Halloween by dressing up and wearing masks once a year, the wonderful people who brought us this exchange played “dress up” for over half a decade and time will only tell if there are any more “masks” to come off in this story. There’s no better or more fitting time to explore one of the darkest realities of the Canadian cryptocurrency space - exactly what is backing any of the cryptocurrency on Canadian exchanges. It’s easy to lose sight that there are real people behind these funds. Most people spend most waking hours working for their money. It literally is their lives. Impacts to victims are not just financial, but psychological and social as well. Victims of exchange fraud go through depression, anxiety, and trauma. They lose their trust and faith in humanity. They withdraw from friends and family in shame and humility. In the spirit of exploring dark and evil things, let’s examine exactly what evidence there is that any of your crypto is backed on any Canadian exchange. This is a continuation of research I’ve been working on since May/June. I hope it will be enlightening and help you better protect your funds that you worked hard for. I’ve done a detailed analysis of all Canadian exchanges I could find that handle any sort of custody of funds, and grouped them into 3 categories:
Not Audited. The only assurance I was able to find that any crypto on the exchange is backed are their words. I was unable to locate any public audit or report of an audit.
Audited. This means that at some point in the past, the exchange invited someone with a reasonable level of credibility, who they showed the wallets to. This person/group, at that point, was sufficiently convinced that funds were actually held by the exchange.
Proof of Reserves. An advanced real time public audit algorithm. It shows that funds exist right on the blockchain, validates access to those funds, and uses a hash tree to enable any customer to verify that their balance is included in the total.
Non-Audited Exchanges (“trust us, we haven't spent your money, we promise")
Bitvo - The service “utilizes a proprietary cold storage solution”. Proprietary, as in, definitely better than established non-proprietary solutions. If you can’t withdraw, they “will credit your account for [their] withdrawal fee”. They’re not an MSB that I could find, nor are they audited. Coinfield - MSB. No audit. Luckily it’s the "most secure trading platform in Canada" - though apparently not the other 150+ countries, including Estonia where they’re based. No matter which country you pick, the “Security” page still says "most secure trading platform in Canada". Coinsmart - MSB. Not sure what "[i]ndustry leading cold storage" is, but luckily they’re so "accountable to [their] clients, community and to each other" and "committed to being open and honest" that they don’t need any audit. Coinut - MSB. Also "the most secure cryptocurrency exchange platform". In addition to not using multi-sig and "not us[ing] USB drives, as the online computer may be infected with virus", they also don’t use audits. Einstein - You can get “your money deposited and withdrawn faster than any other exchange”. As one customer said "With so many hacks and exit scams, it gives me confidence knowing Einstein is backed by hard-working people just like me." Just check the user experience on their subreddit from their "220,000+ satisfied customers". EZ-BTC - As they said, “All your coins are kept in cold storage. They’re safe.” They have “strong security”. The supposed presence of physical ATMs was one of the strategies to build customer confidence and they promised 9% annual return on stored funds. NDAX - MSB. Luckily also “Canada’s most secure trading platform” with "fast withdrawals". I couldn’t find any audit but at least there’s a full page risk disclosure and disclaimer. You can sleep peacefully knowing that they’re legally protected. Netcoins - MSB. The best assurance I could find of solvency is that they “can process large transactions”. Although they don’t waste time with audits or links at the bottom of their website, apparently “[a]ll transactions happen quickly and securely” “within the same day”. Newton - MSB. “No-fees”! Your funds are stored in the "professional custody" of Balance, which doesn’t appear to be a registered MSB. I couldn't find any audit of the funds but they "audit [their] policies and controls". They "publish the reports", but I couldn't find any reports. Simply storing funds somewhere else doesn’t give any assurance they cover customer balances. QuadrigaCX - Operated since 2013, with “vast cryptocurrency reserves” right up to the end. "Bitcoins that are funded in QuadrigaCX are stored in cold storage, using some of the most secure cryptographic procedures possible." Their "cryptographic" procedures are so secure that nobody can access any funds, even now! Shakepay - MSB. Many will trust the raccoon mascot promising “commission-free” trading. No audit found but the “majority of all digital assets on Shakepay are stored securely offline”. Whatever this means, it’s good to know that up to half might not be.
Audited Exchanges ("so and so swears we didn't spend your money, you can trust them, we showed them once before")
Overall assessment: Bitbuy has a long history of buying/selling bitcoin without custody, and is likely too new to offering custody to have been hacked yet. The fact they have taken proactive steps shows promise.
According to the site, they "undergo annual 3rd party financial statement audits", but don’t mention by whom. According to “Newswire”, it’s a firm called MNP LLP.
I was unable to find any published report on the audit, which was completed prior to January 17th, 2019.
Overall assessment: It’s hard not to be a fan of Medium articles describing proactive steps that a company is taking, however without an actual report it can be difficult to assess the integrity of the reserves.
No audit is mentioned on their website, however multiple news sources report that one occurred. According to TechVibes, the audit was completed "by a national accounting firm whose identity is protected under an NDA", which is the best I was able to ascertain from several news sources.
A report about the audit was found as early as September 27th, 2018. TechVibes indicates "the audit covered the operational years of 2015, 2016 and 2017 for Coinsquare, and concluded an “unmodified opinion,” which means the financial statements from those years are “free from material misinformation.”" Other articles had even less information, and I was unable to find any published report.
Overall assessment: The fact that an audit was completed is a great step in the right direction, however the fact the firm is undisclosed by NDA, the audit is completely unmentioned on their website, and minimal details are available should be concerning. It also may be concerning that they claim to be "[t]he most secure trading platform" and also "100% proprietary". This would imply the team at Coinsquare is smarter than established security standards by experts all around the world at protecting your funds, contradicting recently reported incidents.
Kraken - Not a registered MSB in Canada (that I could find)
“So and so” is Stephan Thomas, CTO of Ripple.
The page literally says the audit was done "over the past several weeks", and since the page doesn’t have any date you might assume it’s recent. But look closely at the screenshot and you’ll see a date in 2014! Yes, that’s 5 years ago!
Overall assessment: While it certainly feels good to know an audit was done, the opinion of one individual from 5 years ago doesn’t say much about the state of anything today and they openly admit all kinds of limitations.
Proof of Reserves ("here's your money, right here right now on the blockchain, and here's a proof that we included your balance in that total")
Rather than depend on outdated audits (or lack thereof), it’s actually possible to use the blockchain and cryptography to enable a public real-time audit. This can give assurance to every customer that their balances are fully backed. Giving everyone the ability to check the integrity of balances will keep us all safer. It immediately exposes any fraud, and in most major hacking cases there was advanced hacking that went unnoticed ranging from months (Bitgrail), or years (Mt. Gox). Having an aware public reduces the number of people trading on fraudulent exchanges, and can pressure the exchange to shut down trading or resolve the hack faster, so less funds are permanently lost. To help explain exactly what this is and how it works, I’ve started a detailed tutorial. I did not come up with this algorithm - it was created in 2014 by a guy named Gregory Maxwell. Sometimes cryptography can be hard to understand. Hopefully this tutorial is simple:
Given what can often be at stake, I had hoped that maybe one of the “audited” exchanges might embrace Proof of Reserves. Sadly I haven’t had any such luck. Bitbuy:
Actually they reached out to me in response to one of my posts on Reddit July 14th, asking for detailed feedback on their services.
I provided an extensive summary of my research (I’d just put together descriptions of every exchange for a business plan.)
As of today, that response, which included Proof of Reserves among a multitude of other suggestions, is still unanswered.
On the 4th of July I actually got a response from them to a casual mention where I was recommending their exchange (based on the Medium articles).
Their response, which didn’t address the Proof of Reserves, included the statement “All coins on our platform are 100% secured offline in cold storage“. On their site, Coinberry shows 15 minute withdrawal times in one of the screenshots. Perhaps they have a team standing around “offline” and ready to service withdrawals 24/7.
My subsequent response to them was not answered.
On their website they expressly give reasons why they don’t want "public knowledge of exchanges’ or wallet providers’ bitcoin wallets and total holdings".
They claim it has an effect on security, however public keys do not enable any access to funds - only private keys can. One would hope that their security of funds doesn’t depend on not knowing which wallets they own, since the blockchain is pretty public.
They also claim an effect on user privacy, which is important. Nobody should have any illusion that transactions to or from an exchange are secret in any way. I would highly recommend using privacy coins and setting up new wallets regularly, given that transactions are completely public on the blockchain already.
I was unable to get any clarification, either in live chat or multiple Reddit posts. Understandable, given the size of their operation.
Given that this was their stance after Mt. Gox, it seems unlikely to change based on recent events half a decade later affecting a much smaller exchange.
As such, the bottom line is that present exchanges don’t want to share public keys and offer the kind of transparency which is necessary to enable customers to know their funds are backed. Attempting to get answers doesn’t reveal them, and I’m left with an unnerving silence not unlike the end of Halloween night, like I’m asking questions nobody should ask. Having spent the last 8 months of my life watching and being part of a large group of people suffer through a grueling bankruptcy, where we’ll be “lucky” to only lose 90% of our funds, I want this fixed. I don’t want to live in a reality where fraud can happen just buying/selling on the largest and most trusted exchanges. Especially now that I’ve learned blockchain provides the capability for even greater transparency and a level of public audit far beyond even what's possible with fiat. If you feel the same way, I invite you to join Quadriga Initiative, where we are fighting for a Proof of Reserves future and also enabling businesses to help Quadriga victims with an innovative token recovery project. Every sign-up helps us reach our goal and launch the project! If any information in this post is incorrect, please let me know so I can fix it! Thanks! I’m happy to update the audit status of any exchange given reasonable evidence, or provide a review of any other custodial exchange I might have missed.

#001Infographic Link//Reddit Post Link by thesudio. There’s a lot of good points made, however, these would work better if there is a clear narrative and flow to the information being presented. Otherwise, it can be overwhelming and confusing to the reader. The #1 objective is to visually depict the architecture story and how KMD is redefining blockchain platform architecture.
#002Infographic Link//Reddit Post Link by thesudio. We like that there is a clear structure and clear messaging aligned to each of the 5 pillars. However, the infographic should be focused on telling the architecture story vs the pillars.
#003Infographic Link//Reddit Post Link by VolsenVols. Love how you’ve incorporated our existing graphic design elements into the infographic. This is heading in the right direction and the level of copy and content are well balanced. It would be nice to align this closer to the architecture story and to expand on the different layers of our technology using the same style.
#004Infographic Link//Reddit Post Link by dexter_laabo. Needs to tell the architecture story. This looks more like it took information from our current website. “Anonymous” is not a key aspect of our technology that we’re focusing on.
#005Infographic Link//Reddit Post Link by savandra. The visuals are strong but the narrative could be stronger. It would be nice to align this closer to the architecture story and to expand on the different layers of our technology using the same style.
#007Infographic Link//Reddit Post Link by cryptol1. Doesn’t depict the architecture narrative. Inaccurately describes cross-chain tech as “proprietary”. Simplification has the wrong messaging associated, should be white-label focused. This is considered more of a graphics versus an infographic. Needs to be more comprehensive.
#008Infographic Link//Reddit Post Link by pacosenda. We like the unique design style and approach taken. Doesn’t follow the architecture narrative. Should be expanded out as it is a bit short on content with no clear flow or narrative.
#009Infographic Link//Reddit Post Link by jeanetteLine. Great level of detail and thought on the layout and content. Doesn’t, however, cover the architecture story. Would be preferred if the design direction reflects interim colour and style vs. legacy KMD. The roadmap should be avoided. Looks like they borrowed more from the website than the guidelines.
#010Infographic Link//Reddit Post Link by Meyse. Very creative way to explain and layout the content. This could be expanded out more to encompass the entire architecture story. Cross-chain verifications/smart contracts, blockchain bridging need to be incorporated in.
#014Infographic Link//Reddit Post Link by Limiter02. Good thought has gone into the copy, however, there’s way too much of it. Would prefer stronger visuals and utilizing a more visual storytelling approach. Doesn’t follow the architecture story. Remove the lizard.
#015Infographic Link//Reddit Post Link by piptothemoon. Great thought into visually representing key points. Needs to be expanded out to incorporate the architecture story, but this is heading in the right direction from a visual storytelling POV.
#016Infographic Link//Reddit Post Link by thecryptofoundation. Love the timeline approach, and mostly followed the guidelines and architecture story. Also, like the incorporation of accomplishments at the end. Would like to get the stock imagery used to reflect our interim colour palette. Not all visuals match what is being represented in the copy.
#017Infographic Link//Reddit Post Link by jsteneros. As discussed in the Zoom call, this graphic is really solid but a little heavy on the copy. Would be good to see more visualizations of the info. This graphic hits on some of the important messages (e.g. Komodo is built differently from other blockchain platforms and solves many of the issues that first-gen platforms are struggling with) but it would be great if there was more information about Komodo’s architecture and how Komodo is different from other platforms.
#018Infographic Link//Reddit Post Link by gravigocrypto. This one was also discussed in the Zoom call. Outstanding visuals and overall design. The info follows the architecture story well but could be stronger if the 3 layers of Komodo’s architecture were tied together into one, coherent visual. It’s a challenging task but that’s part of the contest : )
#019Infographic Link//Reddit Post Link by PacoSenda. This is a really creative infographic, which is great! However, we’d really like to see the visuals a bit more in line with fonts and color palette described above in the “First Round of Feedback” section. Also, as with the feedback for many of the infographic submissions, sticking to the Komodo architecture story would be best.
#020Infographic Link//Reddit Post Link by emmanmalaman. The visuals are pretty cool but this one misses most of our core messaging. It would be much stronger if it followed the architecture story and touched on the info provided in this post. There’s definitely potential here but it needs some work.
#021Infographic Link//Reddit Post Link by immimidada. The colors and visuals here are spot-on. It’s also really great that it sets up the problem and then presents the Komodo solution. However, the problem and solution aren’t defined exactly the way we’d like. Check out the architecture narrative to learn more, and try to follow that story a bit more closely.
#022Infographic Link//Reddit Post Link by mohitgfx3. This one is a bit heavy on the KMD logos. We’re really hoping to see a visualization of Komodo’s infrastructure architecture. As with the feedback for many of the infographics, it would be best to re-read Komodo’s architecture story and try to stick to that as much as possible. Using images from the current website is also not a great approach, as we’re preparing to launch a new site in the coming months.
#023Infographic Link//Reddit Post Link by u/sayonara_girl. Some of the visuals are cool! It’s missing the narrative we’re looking for. In general, less copy and more visual storytelling would improve this graphic a lot. We’d like to see a smooth, linear flow of information. Take another look at the architecture story and try to follow that narrative.
#024Infographic Link//Reddit Post Link by brunopugens. This one follows the narrative well! But it’s a little heavy on the copy. It would be much stronger if the architecture was displayed visually, rather than explained with text. Also, the design is cool but it’s difficult to read b/c the perspective of the text is skewed. It’s a really cool idea but might be better to put the text flat for the sake of readability and clarity.
We hosted a round of live feedback sessions via Zoom. The recording is here:
The first block in the KMD blockchain was mined just under two years ago, on September 13, 2016 to 9:04 PM. Since then, Komodo has demonstrated a commitment to innovation and established a history of execution.
Cryptomiso.com is a website that ranks 866 different blockchain projects according to the Github commit history of that project’s most popular repo. Komodo is ranked #1 overall for Github commits over the last 12 months.
China's Ministry Research Initiative regularly ranks Komodo in the top 10.
Lastupdated2018-01-29 This post is a collaboration with the Bitcoin community to create a one-stop source for Lightning Network information. There are still questions in the FAQ that are unanswered, if you know the answer and can provide a source please do so!
Lightning Network White Paper - The protocol has changed since this original paper, but covers the mid-level mechanics of the Lightning Network with an emphasis on the smart contracts that make it trustless
If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily, Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source
How does the lightning network prevent centralization?
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above. All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-) For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user. Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?
Hal Finney, while paralyzed by ALS, wrote code for a bitcoin wallet using only his eyes
It's important to remember Bitcoin's roots, and the amazing effort from brilliant people, like Hal, who contributed to this new technology. If you're feeling down, this is an absolute must read. I have it saved, and read it every once in awhile, enjoy.
"And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go." - Hal Finney, March 19, 2013, 08:40:02 PM
Bitcoin and me (Hal Finney) Copied from https://bitcointalk.org/index.php?topic=155054.0 I thought I'd write about the last four years, an eventful time for Bitcoin and me. For those who don't know me, I'm Hal Finney. I got my start in crypto working on an early version of PGP, working closely with Phil Zimmermann. When Phil decided to start PGP Corporation, I was one of the first hires. I would work on PGP until my retirement. At the same time, I got involved with the Cypherpunks. I ran the first cryptographically based anonymous remailer, among other activities. Fast forward to late 2008 and the announcement of Bitcoin. I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it. When Satoshi announced Bitcoin on the cryptography mailing list, he got a skeptical reception at best. Cryptographers have seen too many grand schemes by clueless noobs. They tend to have a knee jerk reaction. I was more positive. I had long been interested in cryptographic payment schemes. Plus I was lucky enough to meet and extensively correspond with both Wei Dai and Nick Szabo, generally acknowledged to have created ideas that would be realized with Bitcoin. I had made an attempt to create my own proof of work based currency, called RPOW. So I found Bitcoin facinating. When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them. Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs. After a few days, bitcoin was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me. In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there at the beginning. It's one of those glass half full half empty things. The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there. As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they'll be worth something to my heirs. Speaking of heirs, I got a surprise in 2009, when I was suddenly diagnosed with a fatal disease. I was in the best shape of my life at the start of that year, I'd lost a lot of weight and taken up distance running. I'd run several half marathons, and I was starting to train for a full marathon. I worked my way up to 20+ mile runs, and I thought I was all set. That's when everything went wrong. My body began to fail. I slurred my speech, lost strength in my hands, and my legs were slow to recover. In August, 2009, I was given the diagnosis of ALS, also called Lou Gehrig's disease, after the famous baseball player who got it. ALS is a disease that kills moter neurons, which carry signals from the brain to the muscles. It causes first weakness, then gradually increasing paralysis. It is usually fatal in 2 to 5 years. My symptoms were mild at first and I continued to work, but fatigue and voice problems forced me to retire in early 2011. Since then the disease has continued its inexorable progression. Today, I am essentially paralyzed. I am fed through a tube, and my breathing is assisted through another tube. I operate the computer using a commercial eyetracker system. It also has a speech synthesizer, so this is my voice now. I spend all day in my power wheelchair. I worked up an interface using an arduino so that I can adjust my wheelchair's position using my eyes. It has been an adjustment, but my life is not too bad. I can still read, listen to music, and watch TV and movies. I recently discovered that I can even write code. It's very slow, probably 50 times slower than I was before. But I still love programming and it gives me goals. Currently I'm working on something Mike Hearn suggested, using the security features of modern processors, designed to support "Trusted Computing", to harden Bitcoin wallets. It's almost ready to release. I just have to do the documentation. And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go. That's my story. I'm pretty lucky overall. Even with the ALS, my life is very satisfying. But my life expectancy is limited. Those discussions about inheriting your bitcoins are of more than academic interest. My bitcoins are stored in our safe deposit box, and my son and daughter are tech savvy. I think they're safe enough. I'm comfortable with my legacy. [edited slightly] - Hal Finney

Where can you use NAV?
Introduction - What is NavCoin?
NavCoin is a cryptocurrency that has been publicly traded since mid 2014. It's a fork of the latest version of Bitcoin Core with many additional features and functionalities which differentiate NAV from other cryptos.
NavCoin has been one of the first projects to switch to Proof of Stake and is still using PoS to validate and generate blocks. NavCoin didn't have an ICO or a premine. It is self-funded from the beginning and primarily, but not solely maintained by developers of Encrypt-S - the NavCoin Core team (see below for more info about the team).
NAV is trying to simplify cryptocurrencies for the masses. It does this by providing features which make it easy to use like the implementation of OpenAlias, which allows people to send NAV to an email-like address (for example [cryptosif[email protected]](mailto:[email protected])). It also provides very easy to use desktop and mobile wallets.
NAV also provides optional privacy. You can send transactions publicly or private, as you prefer.
It's block speed is really fast with about 30 seconds per block. Transactions are confirmed as spendable within only 30 second which makes it ideal for retail and e-commerce.
High levels of scalability (260+ transactions per second)
It currently has a market cap of 11.6kk (as of writing) and trades for about $0.18 / 4'872 Sats per NAV. The circulating supply is 64kk with no max supply (with an inflation of about 4%).
Staking NavCoin currently yields about 8–10% of your holdings per year. This number depends on how many NAV are currently staking. The minimum return is about 4% (if every single NAV would be staking).
NAV is available on many different exchanges with the biggest ones being Binance, Bittrex and Poloniex.
Introduction The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today. SummerCoin NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds. SummerCoinV2 /NavajoCoin Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features. The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II. SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after. NavCoin On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website . It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014. The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016. Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today. Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.
The Current State
Introduction The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin. Core Team  Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly. Craig MacGregor - Chief Executive Officer Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community. Alex Vazquez - Chief Technical Officer Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology. Paul Sanderson - Lead Software Engineer Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code. Rowan Savage - Senior Software Engineer Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later. Carter Xiao - Lead UX/UI Designer Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that. Matt Paul - Software Engineer Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin. Features of NavCoin  The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest. Static Block Reward The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7. Cold staking To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that? OpenAlias One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone. Community Fund This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this: For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with. After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is. The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected. After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds. The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized. The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-) Proof of Stake Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%. Tutorials And Guidelines  The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines. Tutorials To Contribute To The Website The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow . The NavCoin Developer Manifesto The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements . The NavCoin Content Creation Manifesto Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements . NavCoin Brand Guidelines In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself . NavCoin Educational Series The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately. Community During the last year there have been an influx of software developers from the community starting to create features for NAV. navexplorer.com An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests. NEXT Wallet The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year. There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.
Introduction These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come. Features Rimu - Improved Privacy Solution NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is! Valence Plattform  Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently . Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model .
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity .
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately. The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry. As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.
NavShopper The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities. Kauri Wallet The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features. Kauri Enhanced Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more. Kauri DAEx The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.
If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.
Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next 2 hours I am going to send some NAV to everyone who wants to try out the awesome features and NavPay you read about above. To get your NAVs, all you have to do is the following:
Download the app NavPay from the Android Play Store or as a iOS user, use the NavPay website
Follow the steps to set up your mobile wallet
Backup your private key (the random words) so you could restore your wallet if your phone breaks or something like that!
Post your public address, so I can send you some NAVs
If you liked the experience, I'd be happy to hear back from you :)
Introduction. In this tutorial, we will be taking a closer look at bitcoin's ZeroMQ messaging interface. This interface is useful for developing applications which might require data related to block and transaction events from a Bitcoin core node. Some applications which include block explorers, wallets and reporting dash boards to name just a few. Bitcoin is a peer to peer electronic cash system created by Dr. Craig ... global consensus can be reached on the validity in less than 2 seconds. If a transaction is not accepted by any miners and added to a block template, it is considered invalid. Transactions can be invalid for a variety of reasons such as being submitted with an invalid scriptSig, not adhering to network or miner rules, or ... If the most popular cryptocurrency in the world - Bitcoin was sold at a price higher than 9.000 dollars, after the crash it was sold for a little more than 4.000. It nearly dropped half of its price. Even though it is not the first crash of the cryptocurrency market, it was a sudden one. Not to mention other things like their offices, payment terminals, or bank vaults. It’s easy to attack Bitcoin for its energy usage. Therefore, it’s important to know that there is also an ... There are two variations of the original bitcoin program available; one with a graphical user interface (usually referred to as just “Bitcoin”), and a 'headless' version (called bitcoind).They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and read and write the same data files.
