  • What is the ARK SmartBridge, and how does it work?

    By now many people want to know the technical details of ARK’s SmartBridge but broken down into a less technical and everyday example. That’s what this article will focus on. This article will also assume for examples that most blockchains are already SmartBridge compatible.

    SmartBridge is the ability to connect and communicate between blockchains. By connecting blockchains, we can solve the great question of the last few years in the altcoin community. Which coin will replace bitcoin? The answer… none of them, and all of them. Let me explain.

    With ARK’s SmartBridge Technology every coin becomes even more powerful, every app produced on any blockchain has the potential to reach a greater audience and even bitcoin can gain the functionality of every altcoin through a simple blockchain token called ARK.

    Ark’s SmartBridge communicates between the blockchains using a special data section called Vendor Fields and special Encoded Listener nodes that comb through this data for tasks that it can perform.

    What does that mean? Let me explain…

    In order for ARK to become the medium/intermediary between chains, each chain needs a small snippet of code implemented. It is very easy to insert and not harmful to any blockchain, current or otherwise. Once this tiny code is inserted into the core code of any blockchain, that’s it. Now that blockchain is connected to ARK. We make it painless and extremely simple to implement, and will provide very easy to follow instructions with 24/7 support via slack chat.

    Ok, so what does that REALLY mean?

    It’s quite simple. If you want to trigger an event on a blockchain via a different blockchain, you check if that chain is SmartBridge compatible. If it is, then you can issue a SmartBridge transaction to any compatible blockchain via the ark wallet and the possibilities are endless.

    Example 1: If you wanted to trigger an ETH smart contract but hold ark, you could just send the instructions through ark SmartBridge, right in the wallet to trigger the event. The code embedded in the ETH chain is always listening for an ark SmartBridge transaction and will collect this info and trigger the function to issue a contract.

    Example 2: You want to issue a record entry in Factom, but you only hold ARK. So you would go to your ARK wallet, enter the correct info and instructions for the FCT chain via the SmartBridge tab. Then send it. That’s it, now the FCT chain receives the info and acts appropriately.

    Example 3: I want to send 10 ARK to my ETH wallet. This would require an encoded listener with a back-end ability to exchange currencies. (ie: Shapeshift, Changelly, or Coinbase) Once I send my 10 ARK to my ETH wallet, the encoded listener sees this TX (transaction) as an exchange function and acts accordingly. The encoded listener automatically picks up that this TX needs a conversion, so it acts as a relay node picking up the TX, converting it, and rebroadcasting the TX on its way to the ETH wallet. The encoded listener collects a small fee for processing the TX.

    (Example 3 would require Shapeshift to be its own encoded listener so that it is always looking for the next SmartBridge TX. Just like ARK, Encoded listener nodes set their own transaction fees. Which can be adjusted by the node operator but not ARK.)

    Encoded listeners:

    The Encoded listener node is a hub for listening to SmartBridge transactions. This transaction hub can be setup and run by anyone, Shapeshift, Changelly or even Coinbase. Anyone that wants to act as a medium to help the network can. And in exchange for providing this service they will be collecting transaction fees for passing data or exchanging currencies via SmartBridge.

    I hope this article made it easier for everyone to understand how ARK SmartBridge technology will work. We will be releasing a more in-depth and technical whitepaper for SmartBridge once we get closer to full SmartBridge release.

  • Meet Arky — The Pythonic Way to Work With ARK Blockchain

    ARK is happy to announce yet another official native library under the ARK ecosystem family (which is of course as always, open-source).

    The Python framework to interact with ARK blockchain, codenamed Arky, is a native implementation of cryptographic functions to create and sign transactions, read and write to the vendorfield, together with handy tools to grab information from the ARK network (account balance, pool management, delegate management, etc…).

    This opens yet another HUGE development market that ranges from big Fortune 500 companies, academic and scientific
     computing, e-commerce, aviation, manufacturing, governments, gaming, …— a lot of large institutions use Python as their main
    development language. You can look at some of the more successful Python
    stories on their official website : .

    Arky joins the ARK family of code and is placed alongside many of the already developed libraries for ARK like Javark (a Java lite client communications tool to interact with the ARK blockchain).

    If you have any questions about Arky or need help implementing it in one of the ARK related Python projects, please feel free to get in contact with the main developer of Arky on our Slack.

    1. Join slack :
    2. Direct message user ‘Toons’ :

  • ARK Core Update — Get Ready for Multiple Network Support

    ARK is advancing and improving its core to prepare it for easily deployable custom blockchains and multiple network support, along with constantly improving the base code. Thus, we are happy to announce a new node.js core release moving from 1.0.0 to 1.0.1.

    What has been implemented in this new version?

    • Major upgrade on the core code to support multiple networks. This code upgrade does not change any API features, but enables the deployment of custom networks — ARK becoming the 1st blockchain made for easily deployable custom blockchains based on project/customer/startup/enterprise needs (delegate numbers, transactions per block, block times, … ). A video showing how easy it will be to deploy your own blockchain will be available in the coming days.
    • Resolved peers being broadcast forever, even when they are shut down, leading to lite clients having some transactions not entering the blockchain.
    • Resolved rebuilding from block 0, which caused a stop at block 93477 (read more here on this matter : )

    Hey, what do I, as ARK user, need to do?

    Nothing, the only ones that need to update are delegates or people running ARK main net node on their server(s).  If you are using ARK Desktop wallet be sure you are already using the latest version (1.2.2 as of today) of ark-desktop :

    Hey, I’m a delegate, or I have a relay node running, what do I need to do?

    You will need to update your ARK node with new  Follow these simple steps (once connected to server running ARK node).

    cd ~ rm wget  bash (input your sudo password if asked) Option ‘3’ Update ARK (press number 3 + [enter]) — wait till it completes press[enter] and you are done — easy right?  Now you can get back to monitoring with ‘L’.

    P.S. : Useful tip — if you are an active delegate (one of the 51st) before you update if you don’t want to miss a block look on ARK Explorer when its your turn to forge ( and do it in time before your turn (2–3 minutes should be enough for your node to update and get back to latest block).

    New as you can see has a neat feature when you start it if there is a new ARK core version it will let you know.

    Before latest update:

    After you update to latest version:

    Hey, I am a developer, and I want to launch my own private/public blockchain?

    Stay tuned as a lot of awesomeness is coming to help you get started!



  • ARK Community Fund (ACF) Has Commenced

    We won’t lie — we love our ARK community! At the time of this writing, our official Slack is one of the fastest growing and most exciting in the industry with over 1,900 members in just a few short months. One of our favorite parts of developing ARK has been watching the community grow and getting to know the immensely talented individuals who have chosen to join us on this journey. What our community has already done for ARK is mind blowing and were constantly caught off guard by the ingenuity and drive many have exhibited on a daily basis. Whether it be the huge pool of top tier delegates, the awesome YouTube videos, or our active developer community, we owe you a huge thank you! Hands down, you guys are our family and we love you for all that you bring to the table!

    Today we want to highlight an exciting new initiative being developed by several of our core community members. ARK delegates Jamiec79 and Sidzero have taken the lead in creating something we believe is going to be epic. It’s called the ARK Community Fund or ACF, and we believe it will not only help continue to grow our community, but bring some really great projects under the ARK umbrella!

    What is the ARK Community Fund?

    The ACF is an entirely community owned and operated vehicle for matching developers and entrepreneurs with potential seed funding through the use of the ARK Ecosystem. Potential projects will be able to submit applications to the team running the ACF to be considered for funding generated by an Active Delegate node as well donations from the ARK Community and Delegates. We want everyone to know that this effort has our full endorsement and we could not be more excited to see it get off the ground. So excited, in fact, that we will provide an initial donation of 25,000 ARK to help jump start the ARK Community Fund effort and help get the ball rolling on the first round of submissions.

    Where can I find out more about the ACF?

    You can get full details, rules, and access to the applications from the Official ACF Announcement Thread at the ARK Forums and Official ACF Forum Subsection.

    How is the ARK Crew involved in the ACF?

    The ARK Crew is not officially involved in the management or holdings of the ACF aside from being an initial donor and continued supporter of the effort. At no time will the ARK Crew or any official team member interfere with how ACF is running. This is 100% run by and for the community!

    How can I donate/help the ACF?

    You can donate to the ACF by sending ARK to the following ARK address:  — — — — — — — — — — — — — — — — — — — — — — — — — — — — — —  Ark donation address : ARKCFyhoCVadfhcSAAytfcHHe88EuetcP4 — — — — — — — — — — — — — — — — — — — — — — — — — — — — — —

  • ARKchains — Multiple Ark Ecosystem Networks

    ARK is currently focused like a laser on all aspects of development. Recently, we released a new version of ARK-desktop that supports multiple ARKchains. Many projects are already interested in using ARK codebase, and now we are happy to present updated lite-client libraries (JavARK, ARK-client, ARK-JS) that fully support multiple ARK networks. Projects that decide to develop on ARK codebase will leverage client libraries (for Java, JavaScript, CLI, .NET or Python) removing the need to develop their own. This is one step closer to the vision of SmartBridge where networks will be able to interoperate.

    Tools developed by other ARKchains will integrate seamlessly throughout the entire ARK universe. With our rapidly growing developer community, we soon expect the release of many new tools to interact with ARKchains!

    Currently, there are already 3 projects that will utilize the power of ARK code and blockchain which will be compatible with our SmartBridge function out of the box:

    Also, several private blockchains are now being developed using ARK codebase.

    What does this mean?

    ARK will be the foundation for easy to deploy blockchains with simple to follow instructions and videos. The ARK ecosystem of connected blockchains will continue to grow and communicate with each other with ARK as the primary intermediary connecting them all. Now not only is the ARK core and desktop wallet able to support multiple blockchains, but developers can now freely use their favorite programming language(ie: Java, Python, .NET) which now also support multiple blockchains.

    Stay tuned for the next wallet update to include a very cool new feature that will tie into the future of IPFS integration.

  • GoARK — Let’s GO Towards New Horizons

    ARK is quickly becoming an all around development tool with a vast list of programming language integrations. Making ARK available to more and more developers as we build our ecosystem. These integrations enable a wide range of development to be built effectively using ARK for any applications wanting to utilize the power of the ARK Ecosystem!

    Our latest in this series of language implementations is named GoARK, a library for the Go (GoLang) programming language developed by Google. This will be our 4th native language implementation (in addition to Java, Python and .NET) on top of our Javascript Delegated Proof of Stake blockchain.

    GoARK on ARK GitHub:

    Golang was explicitly engineered to thrive in projects built by large groups of programmers with different skill levels. Go’s trade-offs are not unique, but it’s a good set of trade-offs and thanks to them, Go is happening.

    Look at how GoARK works in action :

    This is a demo app built using the GoARK library. A cross platform build is also available.

    What is GO?

    The goals of the Go project were to eliminate the slowness and clumsiness of software development at Google, and thereby to make the process more productive and scaleable. The language was designed by and for people who write, read, debug, and maintain large software systems [Source].

    Golang is gaining a lot of traction. It is used by globally recognized projects from companies like Google, Netflix, SoundCloud, Dropbox, MongoDB, and Docker, to name a few.

    Go can be treated as the result of a rather conservative language evolution from languages such as C and C++. Go is already a big player in server software, and is continuing to extend its reach. Go overcomes some of the limitations of those languages, like lack of parallel computation support, shortcoming on multi-core support, and memory management, to name a few examples. The high performance is in large part due to the static compilation of the statically-typed Go code.

    The Internet of things powered by ARK-GO

    The Internet of Things framework requires a robust and dependable programming language. Looking at many of the tools today, you really have 2 or 3 popular options in this space: do barebones C/C++ or have a NodeJS integration. GOLang implementation provides answers to IoT challenges and strengthens it with the power of the ARK Blockchain. It is made to run and co-exist with ARK.

    Cross compilation with Go

    Golang has cross compilation support built right into the core system. Just by setting the right parameters and running the command “go build”, you get one executable file that can be run on multiple platforms. For example:

    set GOARCH=amd64
    set GOOS=linux //we can also set windows, darwin…
    go build

    Simple. No overhead of installing frameworks and other supported libraries, this is where the statically typed simplicity and natural language evolution shows its core strengths.

    Concurrency and GO on Mobile Systems

    “Go-routines” in Go, enables concurrent function processing. These channels are used for components to communicate with one another and synchronize the execution. Go also supports application development softwares like Android and iOS. An application written in Golang can directly be launched into both Android and iOS. It is an active supporter of Android NDK (parts of the application are implemented in native language such a C++/C ).

    Golang is awesome, and using it spreads the wings of creativity, with high rate of efficiency and performance for the developers and users.

    GoARK was developed by chris (click to DM him on Slack). If you have any GoARK related questions please don’t hesitate to contact him on our Slack.

  • ARK To Be Available On Ledger Nano Wallet

    ARK is proud to announce our partnership with Ledger Hardware Wallet. ARK/Ledger integration has been in the works for a while now and we are very excited to finally release it.

    ARK integration into the Ledger Hardware Wallet makes ARK the tenth cryptocurrency to be secured by this amazing piece of hardware. Ledger provides additional security measures and the ability for you to store your ARK safely, with peace of mind along with other major cryptocurrencies supported by Ledger.

    ARK and Ledger are making two firsts with this addition

    ARK is now the first Delegated Proof of Stake (DPoS) blockchain and the first JavaScript blockchain ever to get native integration into the Ledger Hardware Wallet.

    But there is more: ARK-desktop and upcoming ARK-mobile wallets will be compatible with Ledger wallet, and BIP32/BIP44 compliant. This means you will be able to generate HD wallets with extra security without having any single passphrase getting out of the Ledger device. This also means you can create an ARK address directly from your Ledger device. Once we have full compatibility with the Ledger Hardware wallets, we will also provide Ledger Hardware wallet support to our Desktop and Mobile wallets that will require the use of the Ledger to sign transactions if the ledger account is synced to the Ark wallets.

    But there is even more: Any future ARK cloned network, ARK fork, or ARK test-net/dev-net will be compatible with the ledger in the near future. Making every ARK cloned chain Ledger compatible.

    The scheduled release date is July 28th, 2017. ARK will be available on Ledger Nano S and Ledger Blue.

    What is a Ledger?

    Ledger is a cryptocurrency hardware wallet for storing cryptographic assets and securing digital payments like Bitcoin, ARK, and other altcoins. It connects to any computer (USB) and embeds a secure OLED display to double-check and confirm each transaction with a single tap on its side buttons.

    With Ledger Nano S, secrets like private keys are never exposed: sensitive operations are isolated inside your hardware wallet within a state-of-the-art Secure Element, locked by a PIN code. Transactions can’t get tampered with, they are physically verified on the embedded screen with a simple press on a button.

    You can send and receive payments, check your accounts and manage multiple addresses for each currency from the same device. Nano S also supports the FIDO® Universal Second Factor standard that simplifies the authentication process on compatible online services such as GMail, Dashlane, Dropbox or GitHub.

    Your ledger accounts are backed up on a recovery sheet. Making restoration of lost/damaged devices easy with any Ledger device or compatible wallets (BIP39/BIP44).


    • Ledger Nano S is based on a dual chip architecture (ST31/STM32, Certification level: CC EAL5+). The firmware integrity is guaranteed by cryptographic attestation.
    • The Ledger Nano S ensures only you can access your accounts by requiring a 4–8 digit PIN code each time it is plugged to your computer.
    • Initialization or restoration of your configuration is fully done on the secure environment of the Ledger Nano S. Your cryptographic secrets are never exposed to the outside world.
    • Your private keys are never held or known by Ledger or a third party: they are hard locked in the Secure Element. With Ledger Nano S, your wallet remains decentralized, you are your own bank.

    Limited Edition ARK Nano S

    You will also have a chance to order a Special Limited Edition Ark branded Ledger Nano S — there will only be 1,000 of these devices ever made so make sure you order your piece of history when they become available.

    Scheduled Release of ARK branded Ledger Nano beginning in early August 2017. Stay tuned to our social media (Twitter/Facebook/Reddit/BitcoinTalk) accounts to learn how you can own your very own ARK Ledger. Or join our announcement channel in our Slack.

  • Ark Desktop Wallet Update —v1.3.1 | New Windows OS installer | Electron Update

    We did a quick update to address some of the issues that our community reported with the previous Ark Desktop Wallet release (v1.3.0).

    To update to 1.3.1, if you are running 1.3.0, you can simply click on the button saying “New Version Available!” in the left upper area beside the logo. It will take you to GitHub where you can download the latest version.

    • Aligning the “quit” button/icon with other buttons/icons.
    • Memory leakage experienced by some from leaving Ark Desktop Wallet open for extended period of time has been fixed. There are still some reports of high memory usage after leaving Ark Wallet open for an extended time frame, mostly running on Windows OS. If you are experiencing this, you can simply open and close wallet. We are still looking into possible causes. Please report any occurrences at so we can eliminate all possible memory leaks in future Ark Desktop Wallet releases — thank you.

    Features Added:

    • Option to see public key of your Ark Address.
    • Option to also view 2nd passphrase when entering (if you have it registered of course).
    • Updated version of Electron (Chrome / Node / v8).
    • New Windows OS installer.

  • ARK Desktop Wallet Update — 1.3.2 Mandatory for Ledger Hardware Wallet Users

    The moment you have all been waiting for is here. ARK and Ledger have been working together testing the integration between the Ledger hardware wallet and the ARK desktop wallet and now we are ready to release the new wallet update, making it possible to sign transactions and vote with your Ledger via the ARK desktop client.

    This update is MANDATORY if you want to use a Ledger Nano S with the ARK Desktop Wallet to sign your ARK transactions. This is only for the ARK desktop wallet to communicate with your Ledger Nano S.

    Download the newest ARK Desktop Wallet here:

    Or simply click the “New version available!” button in the upper left corner of your ARK desktop wallet. You will be brought to the appropriate download page on our GitHub.

    NOTE: You DO NOT need to register your 2nd passphrase with Ledger Nano S accounts.

    If you are looking for general Ledger knowledge base, such as adding ARK to your ledger, please go to and follow their instructions.

    Mini quick guide on how to use Ledger with 1.3.2 wallet (more detailed guide coming soon):

    This Ledger wallet update is still in beta. Please report any bugs or feedback to us immediately so we can improve and update the UI!

    But this is not all that has been merged in this new desktop wallet release:

    • New ‘Select’ option for currency. (Now the user can quickly change to the currency of their choice without having to cycle through the entire list.)
    • Improved scrolling in account dashboard. (The buttons on the main screen are moved to the header which is now attached to the top — a better UI experience for those who have many ARK accounts.)
    • Implemented input check against hex in message verification. (when verifying a message, additional checks have been implemented.)
    • Save/import signed transaction file. (implementation of a new feature to save the signed transaction to JSON file and import it later to broadcast.)
    • Timeserver update. (ARK Desktop wallet now gets the time from a server for better time management.)
    • Appropriate network symbol in transaction window. (If you are using other tokens like DEVNET ones, the ARK desktop wallet now displays the appropriate symbol when making a transaction.)
    • Removed ‘type’ column in transaction list. (Type of transaction has been removed in transaction history list for more clean look to match explorer transaction history overview.)
    • New currencies and ARK desktop wallet translations added. (A lot of new currencies and languages have been added to select from in the settings.)
