  • Waves ‘sidechains’: bitcoin gateway goes live

    A secure, reliable bitcoin gateway enables users to hold bitcoins on the Waves network — moving them around with the speed and efficiency of Waves, rather than on the slower and increasingly costly bitcoin network.

    Bitcoin is here to stay. Its network effect and battle-tested security make it the first, the largest and the default currency of the crypto world. Vastly more money is transferred as bitcoin than any other digital currency. Alts trade against it. It is the reference currency and the reserve currency of crypto land.

    Unfortunately, bitcoin’s greatest strength is also its chief weakness. Decentralisation brings with it freedom from outside interference. It also means that development is slow, and it is hard (perhaps even impossible) to achieve consensus about changes to the protocol.

    And so we have the current situation, in which bitcoin transactions are backing up, and consequently fees rising sharply. A year ago a transaction with a fee of 0.0001 BTC would go through almost immediately. Today, the same fee might lead to a delay of 48 hours before a miner picks it up. With the recent bull run, the fee necessary for a fast transaction isn’t just higher in BTC terms — it’s higher in dollars too. This means that the cost of a fast transaction can approach that of moving money in the legacy banking system.

    There are various proposals to fix this issue, all of which have met with a mixed response. It is hard to keep all of bitcoin’s various stakeholders — miners, end-users, wallet companies and businesses, amongst others — happy at the same time. Raising the block size has proven divisive, to say the least. There has been support for sidechains, but the technical hurdles are significant.

    ‘Pseudo sidechains’

    Sidechains can be thought of as a black box in which transactions occur, ultimately settled on the bitcoin blockchain, but without every transfer being registered individually. What happens in a sidechain stays in a sidechain. Funds are locked to an address using a smart contract, and within the system of the sidechain may be moved around thousands of times to different addresses, before exiting back onto the main blockchain. It’s an ingenious way of using bitcoin’s blockchain for vastly higher transaction volumes, without bloating it to the point of uselessness.

    The Waves bitcoin gateway functions, conceptually, in a similar way. Funds are securely ‘locked’ when they are deposited to the cluster of servers that hold BTC in multi-sig storage, with a token being issued on the Waves blockchain to represent them 1:1. Those Waves bitcoins (WBTC) can then be moved around on the Waves blockchain, with its advantages of speed and scalability. Whilst this may not have the theoretically unbreakable security levels of smart contracts (assuming they are implemented correctly), security is nevertheless extremely robust and far in excess of that of traditional exchanges with their single-point-of-failure problems.

    For cold storage, when funds are not moved for long periods, the bitcoin blockchain is the best option. But when funds are being moved around frequently, perhaps being used as a means of payment in BTC (i.e. not moved to an exchange), WBTC can profitably stay within the Waves system. It is only when they need to be moved to an exchange that the bitcoin blockchain is required again — assuming that exchanges do not integrate the WBTC token. This makes it easy and efficient once again to move BTC around. Higher costs and/or delays are only incurred when exiting to use the bitcoin blockchain.

  • The Growing WAVES in the Crypto Ecosystem


    Guy Brandon


    Aside from existing token creation and transfer features, the client now offers a bitcoin gateway to allow BTC to be securely stored and transferred on the Waves blockchain. Transaction volumes on the network are rising rapidly.

    An updated version of the Waves lite client has been released, with powerful new functionality aimed at real-world use cases. As before, the lite client offers a familiar and straightforward user experience, and requires no blockchain downloads – making it suitable for anyone to get started with cryptocurrency applications. The client can either be downloaded and run as html, or as a standalone Chrome app that automatically updates when new versions are released. The network is secured by full nodes run by members of the community. For security reasons, a minimum of 10,000 WAVES is currently required to run a mining node.

    Token facilities

    In addition to being able to transfer the native WAVES currency, which is the fuel for the Waves platform, the lite client makes it extremely easy to create and send new tokens. Custom Application Tokens (CATs) are secured on the Waves blockchain and can be launched in minutes. These assets are shown in the Portfolio tab in the wallet.

    Mass distribution to a large number of addresses is also possible, making Waves the ideal platform for crowdfunding and distributing new tokens. This has made Waves attractive for a growing number of blockchain businesses and applications. These include:

    • Waves Community Token. A token used to reward WAVES holders through periodic airdrops and engage the community, including in the process of collective due diligence for new crowdfunded projects.
    • Incent. A blockchain-hosted loyalty programme, based on the principle of ‘Open Value’ rather than the restricted value of traditional rewards points.
    • Bankcoin. A far-reaching initiative to introduce cryptocurrency payments into universities in Latin America.
    • Upcoin. A project launched by a Russian political party to engage and reward active members, and use the blockchain for voting. This is the first ever blockchain platform used by a political party.
    • Ripto Bux. A community project founded around the idea of a tipping currency, Ripto Bux (RBX). A Slack tipbot enables anyone to create, send and receive Waves tokens as tips, with RBX being the default tipping currency. Ripto Bux also uses the BlockSwap technology developed by Incent to transfer tokens securely between the Waves and Ethereum blockchains.
    • New projects are coming to Waves all the time. On 25 April, MobileGo will launch a major crowdfund to drive cryptocurrency adoption within the gaming sector. Over the coming weeks and months many new businesses will launch their own tokens and crowdsales on Waves.

    Bitcoin gateway

    The Waves bitcoin gateway allows users to deposit and withdraw bitcoins to and from the Waves blockchain. Coinomat servers process bitcoin deposits and exchanges them for the equivalent amount of the WBTC token. This can be sent quickly and at low cost between users within the Waves blockchain. Upon withdrawal, the gateway conducts the same process in reverse, swapping WBTC for BTC, which are sent to a designated bitcoin wallet address. WBTC are always backed 1:1 by real BTC.

    The gateway means that Waves can function as a kind of ‘sidechain’ to the bitcoin blockchain, offering greater speed and efficiency, but always giving users access to their bitcoins when they wish to withdraw them.

    Android app

    The Waves client is now available as an Android app. This can be downloaded from Google Play. It is a convenient way to access your Waves account on the go from a mobile device, and offers much of the functionality that the fully-fledged lite client does in the Chrome app. It is possible to import the SEED from which an existing address has been created, in order to use the same account from multiple locations and devices.

    Things happening in the Waves ecosystem

    Waves development is highly active, with numerous features and approaches being prepared.

    • The Decentralised Exchange (DEX) will enable users to trade Waves tokens peer-to-peer, directly from the lite client. The DEX back-end code is complete, with release pending front-end integration.
    • Fiat gateways are being implemented, starting with a Euro gateway. This will allow users to transfer fiat on the blockchain, with the lower costs and greater speed this provides.
    • Balance leasing (LPoS or Leased Proof-of-Stake). WAVES holders will be able to lease their balances to full nodes to help secure the network and receive rewards from transaction fees, while maintaining full control of their funds at all times.
    • Transaction fees will be payable in tokens, subject to full nodes accepting them as payment. WAVES will always be accepted, but this feature means that applications built on Waves will not have to worry about the additional friction and complexity of providing a second currency for fees.
    • Improved Authenticated Dynamic Dictionaries
    • POS NG
    • Smart contracts roadmap, which are to be implemented on Waves. These will be non-Turing complete, but still extensive and powerful.

    Rising transaction volumes

    Since the beginning of February the number of transactions on the Waves blockchain has been increasing rapidly. It currently averages around 5,000 tx/day, though as many as 15,000 have been recorded. For comparison, Ethereum sees around 60,000 transactions per day and bitcoin around 300,000. Few cryptocurrencies have such high levels of activity, with even Litecoin averaging around 7,500 tx/day.

    As new businesses launch tokens and use cases on Waves and as the DEX comes online, we expect to see transaction volumes increase further and significantly, driven by real-world adoption – rewarding mining nodes and those who lease their balances to them.

  • Three ground-breaking crowdsales coming on Waves Platform

    MobileGo, EncryptoTel and ZrCoin are all launching crowdsales in the coming weeks — and all are unique in their own way.

    With the release of the Bitcoin gateway and with DEX and fiat gateways in active development, Waves platform is coming of age. A series of projects have already launched on Waves, thanks to its powerful and accessible token facilities. Over the next two months, at least three major businesses will hold their own crowdfunds — each of them addressing the needs of a different sector with the unique proposition offered by blockchain technology.


    Zirconium Dioxide (ZrO2). It’s not sexy, but it is highly in-demand as a refractory material in the production of ceramics, amongst other things. A team of international researchers have come up with a way to extract it from waste materials, rather than mining it from the ground. The result is a higher-quality, more cost-effective and environmentally-friendly form of zirconium. The Russia-based team is seeking to roll out production on a larger scale, but venture capital funds come with unacceptable strings attached and the banks won’t deal with projects this small.

    ZrCoin’s solution is a blockchain-based option for ZrO2. It’s the first such blockchain commodity of its type, making it an innovative financial as well as technological project. Investors will buy an option for ZrCoin, each representing 1kg of synthetic ZrO2, at a discount during the crowdfund. This will be bought back at market price once production and sales are under way. As a commodity-backed token, it will be freely transferable but also stable in value — making it a way for traders to park or store value on the blockchain.

    ZrCoin’s crowdsale will launch at the beginning of April and will last for 30 days. For more information, register on the website.


    The telecommunications industry is expanding rapidly thanks to the growth of new VoIP technologies, though older telephone infrastructure is falling from use. Most offices typically use a form of IPPBX (Internet Protocol Public Branch Exchange), an internal phone network hooked up to the internet as well as the external phone system. These can be fairly inefficient. Additionally, the more we communicate, the more surveillance becomes a problem, whether that is conducted by home or foreign governments, corporations or hackers. Aside from the civil liberties issues associated with this, industrial espionage is an increasing issue.

    EncryptoTel’s Team met whilst working for a telecommunications company and realised they could create a solution that was better than anything currently on the market. They have already built a working beta for a virtual PBX that can be deployed and used by anyone, individuals or companies, with no additional hardware or infrastructure required beyond an existing internet-enabled device and a web connection. All communication is encrypted, payments using cryptocurrencies are enabled for added privacy, and the multiplatform approach supports a wide range of softphone and communications apps for video and audio calling and instant messaging.

    EncryptoTel’s crowdsale will open on 1 May and will last for one month. The funding will allow them to complete their product and market it aggressively into the VoIP sector.


    Gaming is a $100 billion industry and growing fast. Large amounts of money are moved into and out of in-game economies every day, but this is an inefficient process that is riven by problems thanks to the nature of the legacy banking system. Deposit limits, delays and poor exchange rates make it difficult and frustrating for gamers to transfer cash to their chosen games.

    Gamecredits has been working to address this issue for three years. The cryptocurrency is a Litecoin clone, just about the simplest of crypto tokens, since that’s all it needs to be. Using GAME, it’s possible to move money into and out of, but also between, games — with the near-frictionless payments that blockchain currencies allow. It’s an ideal use case for crypto, and one that has been picked up by a major developer,Datcroft, who are helping to market the idea to the entire gaming industry.

    MobileGo is the marketing fund for that project. It’s designed to drive GAME adoption within the gaming industry through a very neat mobile gaming platform that has already attracted hundreds of game developers. All game payments will be channelled through GAME, increasing demand markedly, whilst MobileGo will receive revenues from the commission paid on this when users buy it through the credit card-enabled GameCredits wallet.

    The MobileGo crowdsale begins on 25 April and will last for one month. You can find out more on the GameCredits website.

    These three projects alone show how blockchain tech is going mainstream in 2017 — and there’s plenty more coming for Waves.

  • Waves unveils new website for next phase of adoption

    The Waves Platform website has been given a full revamp as it releases new services and positions to become the foremost custom tokens blockchain application.

    Tokens 101

    Waves was designed with mass adoption in mind and focuses on custom token operations. ‘We believe that these very basic facilities — creating, distributing, transferring and trading simple tokens — will be the forefront of blockchain adoption,’ explains CEO Sasha Ivanov. ‘This is the functionality that businesses are exploring now and want to implement in their applications. We want to make it as easy as possible for businesses to deploy their custom tokens, and for their customers to use them.’

    The new website explains exactly what a blockchain token is — knowledge that cannot be assumed for newcomers seeking to explore the benefits of distributed ledger technology for their businesses — before offering a straightforward tutorial for creating tokens on Waves. ‘Waves is “Blockchain for the People”, and we mean to makes these powerful tokens facilities available to everyone, without a significant technical overhead,’ continues Ivanov.

    Key projects

    As well as introductions and guides, the site lists some of Waves’ flagship projects — applications that have crowdfunded on the platform and are already up and running using Waves technology. Each are represented by a token on the Waves network. These include WBTC — a bitcoin token that allows Waves users to store, send and receive bitcoin on the Waves platform via the secure Bitcoin Gateway — and the Waves Community Token (WCT), which allows holders to participate in collective due diligence for new projects and to benefit from regular airdrops. Third-party projects such as Darcrus and Incent are also included, offering some sense of the growing ecosystem building up around the core Waves technology and infrastructure.

    Optimised for convenience

    Lastly, the site has been fully optimised to give a faster, smoother experience, and to ensure it is better suited for mobile browsing. ‘Our attention is always on users. During its early period of development blockchain technology was difficult to use. Everything was very technical and hard for users — cryptocurrency clients, blockchain downloads, complicated and unreliable exchanges and other services, and even finding the information you need to get up and running. Waves aims to change that for every element of blockchain adoption, from our website right through to the wallet itself.’

  • WavesPlatform Excited To Announce MobileGo Crowdsale April 25th

    As you may have heard, MobileGo is launching a crowdsale starting April 25th on the Waves platform. MobileGo is a smart contract token and the backbone of three decentralized mobile gaming products: a virtual marketplace for the trade of in-game content, gamer to gamer match play plus wagering and decentralized tournament play.

    All three of these products will exist within the Gamecredits Mobile Store, an android app two years in development, launching Q2 of this year. The Gamecredits Mobile Store has hundreds of games and gaming developers signed on to its initial launch from over a dozen countries. Plans are to have over 1000 games on the platform by the end of 2017.

    MobileGo will also be the first large token issuance to be done on both the Waves and Ethereum blockchains. This is being done to leverage technical advantages of both, while also bringing wider recognition to the Waves platform in the larger crypto space. The team of Ethereum developers we have employed look forward to working with Waves to find ways the two communities can work closer together in the future.

    The MobileGo team is diverse, with industry leaders in the gaming industry and crypto space. Our developers span Australia, Europe, and Russia with offices in the U.S., Western and Eastern Europe. MobileGo already has established partnerships in China, Japan, and over a dozen other countries to help promote this crowdsale and expand the MobileGo product reach.

    For more information or to register for updates please visits www.mobilego.io.

  • Waves Release Testnet v0.6.2

    Testnet v0.6.2

    • Minor improvements and fixes.


  • Credit card purchases integrated within Waves client

    It is now possible to buy WAVES and bitcoin with a credit card, depositing BTC directly into the Waves client as a native blockchain token.

    Waves has implemented credit card purchases for WAVES and bitcoin within its lite client via a partnership with Indacoin. The bitcoins purchased will be delivered directly to the user’s wallet as a WBTC token via the Waves bitcoin gateway, or instantly converted to WAVES if preferred. The service is best suited for buying small amounts of BTC and WAVES, in order to use the platform’s token creation and distribution facilities.

    Gateway deposit

    Users can already deposit bitcoins to their Waves wallet using the bitcoin gateway. The gateway processes bitcoin transfers and exchanges them for the native Waves bitcoin token, WBTC. The token is backed 1:1 with bitcoins that are stored in a multi-sig account, managed by a cluster of secure servers. New fiat gateways will be added in due course, starting with a Euro gateway.

    An additional option has been added to the BITCOIN and WAVES Deposits tab in the client. A pop-up dialogue allows users to buy cryptocurrency with a credit card. On confirming they want to continue, the user is redirected to Indacoin to complete the purchase. The bitcoins are then deposited to the user’s Waves account via the bitcoin gateway, as normal, or converted on-the-fly to WAVES. An exchange rate calculator within the client ensures that users know how much cryptocurrency they will receive at the point of transaction.


    Credit card processing has been outsourced to Indacoin, an instant exchange platform that allows fast and easy purchase of bitcoins. Indacoin is well-established in the bitcoin space and has been offering credit card purchases since 2014. No registration is required.

    ‘Whilst we’re lining up gateways that will enable users to move larger amounts of money into and out of the Waves system efficiently, credit card purchases allow anyone to buy bitcoin and WAVES quickly and easily,’ comments Sasha Ivanov, CEO of Waves platform. ‘So they can access token creation facilities on the platform — something that will be necessary as we target mainstream adoption and facilitate entry into the rapidly-growing blockchain crowdfunding sector.’

    Indacoin deals with the problem of chargebacks through an enhanced verification process. To ensure that the owner of the card really does want to purchase bitcoin, a call is placed to the buyer’s mobile and a four-digit code provided for confirmation on the site. A spending limit applies for first-time buyers, which is progressively raised for later transactions. Visa and Mastercard credit/debit cards can be used.

    In due course, it will be possible to trade WBTC and WAVES against other tokens on the platform’s decentralised exchange (DEX).

  • Incentivizing POS mining.

    We’ve launched a new asset, Miners Reward Token. The idea behind it is mining incentivization, more people should have a reason to maintain a full node. It’s important for POS systems, since in a usual set-up all you get in proof-of-stake blockchains as a miner is transaction fees, which are not so big if you don’t have tons of transactions in the network. Probably it would make sense to create a POS system with a block mining bounty as in Bitcoin, but it’s not so easy conceptually, since in POS systems all native tokens are distributed in the genesis block.

    So,as a temporary solution, (as long as we don’t have tens of thousands transactions in the network per hour), we will be rewarding miners with a new asset https://t.co/YV4rZdzRTn. Each miner will be receiving 50,40,30,20,10 tokens per mined block, with “halving” taking place each 50000 blocks. The asset will be distributed in about a year.

    So where does the value of this asset come from? As you know you can get mining fees on Wavesplatform not only in waves but also in custom tokens. So token issuers should have an incentive to strike a deal with miners regarding accepting their assets as fees. An automated way to do that would be distributing some bounty in the asset to active miners. That could be done through distributing it to the MRT holders, which are exactly that, miners.

    On top of that, miners will be able to vote for certain network parameters and issues, similar to the proposed scheme for Waves Community Token. This is a quite flexible tool, so many other ways to use it could come up later.

    Blockchains are technical mechanisms of social consensus, so it’s very important to engage system participants in securing and maintaining the network. I believe that MRT is a right step in this direction.

  • Liquid.pro to record all stock options orders on the Waves blockchain platform

    Over-the-counter trading service Liquid.pro is transferring its quotes on stock options entering the Moscow stock exchange to the public Waves blockchain platform. The use of blockchain technology in trading will increase transparency and ensure greater fairness of order execution.

    Liquid.pro’s over-the-counter order service has organised the transfer of its register of applications on options entering the Moscow stock exchange onto the public Waves blockchain platform. The full list of applications is available for users on the service’s site: http://blockchain.liquid.pro/.

    Applications remain anonymous, with each user receiving a unique hash address that allows him to identify his applications on the list. The use of blockchain technology ensures high reliability and absolute transparency of the service. Once operations recorded in a block are verified, their history cannot retrospectively be overwritten or canceled, and the information is open and accessible to any interested parties.

    ‘Liquid.pro is focused on long-term, strategic work, so we could not ignore a technology as promising as blockchain. We chose Waves as a solution because the platform’s public blockchain provides high reliability and stability of work, and the development of the platform is aimed at supporting business needs. We plan to develop further cooperation,’ comments Aleksey Yurov, head of blockchain department at Liquid.pro.

    Active development of blockchain applications for trading is driven by two main factors. Firstly, the use of the new technology ensures transparency of operations, which is extremely important for a process in which players participate from different perspectives. Secondly, the blockchain significantly reduces transaction costs.

    ‘Further efforts should be directed at transaction settlement. At the present time, this operation requires extensive resources, largely due to the fact that the participants in the process are working in different environments. The interaction of traders, brokers, stock exchanges, depositories and clearing organisations is a complex and rather expensive procedure. The use of blockchain technology can help to optimise this process, uniting participants within a single platform and allowing the automation of numerous stages of work,’ explains Alexander Ivanov, founder and CEO of the Waves blockchain platform.

  • Waves Launches Decentralized Token Exchange 'Matcher'


    Guy Brandon

    Email [email protected]

    The Waves platform is releasing two of its signature features on mainnet: the decentralised exchange (DEX) and Leased Proof-of-Stake (LPoS).

    The Waves blockchain platform is launching its decentralised exchange (DEX) on mainnet. DEX can be accessed via a full node or the API at start, but will be available in the lite client for all users in due course.

    At the same time, Leased Proof-of-Stake is being released on mainnet which will allow anyone to lease their mining power to a full node and receive rewards while increasing network security.

    New transactions will be available on mainnet on April 3, 2017.

    Waves DEX: speed and flexibility

    Early decentralised exchanges have been created on other cryptocurrency platforms. However, they suffered from a series of issues that prevented them gaining a critical mass of users. Waves’ DEX offers the following unique features and advantages:

    • Asset-to-asset trading. Waves allows direct trading of any two tokens.
    • Speed. Trades will be executed near-instantly thanks to the matching engine, but are still settled on the blockchain. This means that traders can be confident their trade has been processed, whilst maintaining security and having full access to their funds.
    • Crypto and fiat tokens integration. Users will be able to trade most popular crypto and fiat assets represented by corresponding tokens. Waves’ low fees will also make high-volume trading possible.

    When the GUI is completed for the DEX and integrated in the lite client, traders will enjoy a familiar, straightforward user-experience. The DEX’s interface will be immediately recognisable, similar to the bitcoin/altcoin exchanges that are a key element of the cryptocurrency world.

    Matcher nodes

    The Matcher enables near-realtime trading thanks to a completely new piece of technology. Matcher nodes pair buyers and sellers, executing trades instantly whilst still ensuring these are ultimately settled on the blockchain for maximum transparency and security. Previous decentralised exchanges have proven slow and unreliable, because it was impossible to know whether an order had successfully been filled until a block was confirmed.

    Matchers will receive fees for the service they provide, adding another revenue stream for Waves full nodes. 

    Leased Proof-of-Stake

    In addition to the release of DEX on mainnet, ordinary users will be able to lease their mining power and receive rewards from the fees from transactions that the node processes – yet the holder maintains full control over his funds, and can cancel the lease at any time. Only two transactions are required: Lease and Cancel. WAVES mining power is leased to an address associated with a full node. Leasing will shortly be implemented within the lite client.

  • Waves DEX live on mainnet: how to post orders

    Waves’ decentralised exchange (DEX) has been deployed on mainnet and Matcher transactions are live. You can currently access it via a full node. In due course it will be integrated with the GUI in the lite client, allowing anyone to use it without any technical knowledge or blockchain downloads. For now, here’s some more information about how to post orders.

    If you want to post an order for the Waves DEX, you’ll need access to a Waves node. At this point, that either means running your own node or signing a transaction offline and sending it to an open one. If you need more information about setting up a node, read https://github.com/wavesplatform/Waves/wiki/How-to-install-Waves-node or ask for help in the #fullnode channel of Waves Slack.

    Matcher nodes are responsible for pairing orders and executing trades quickly, whilst they are still settled on the blockchain. You’ll need to send your orders to a Matcher. Peter Black (@pblck), who helpfully provided information for this article, has an open one at http://dev.pywaves.org:6886. If you visit http://dev.pywaves.org:6886/matcher/orderbook you can see the listed pairs.

    To sign an order (buy or sell) you need a node, go to /assets/order and post something along the following lines:

    {  “senderPublicKey”: “YOUR_PUBLIC_KEY”,  “matcherPublicKey”: “YOUR_MATCHER_PUBLIC_KEY”,  “assetPair”: {  “amountAsset”: “AnERqFRffNVrCbviXbDEdzrU6ipXCP5Y1PKpFdRnyQAy”,  “priceAsset”: “”  },  “orderType”: “buy”,  “price”: 10000000,  “amount”: 100000000000,  “timestamp”: YOUR-TIME-STAMP,  “expiration”: YOUR-EXPIRATION-TIME-STAMP,  “matcherFee”: 100000 }

    YOUR_PUBLIC_KEY is the public key of the buyer/seller (you can get this from the backup tab of the lite client)

    YOUR_MATCHER_PUBLIC_KEY is the public key of the matcher, which can be obtained from from /matcher on the matcher URL. E.g. GoVxp9iFXvDhGFUYG4fZ4GU3yQDsxyti8f3D5tNYiAXX in the case of the given node.

    amountAsset/priceAsset is the pair: in the example above RBX/WAVES, but you can post orders in any pair of tokens.

    timestamp and expiration are Unix epoch timestamps. There are several ways to generate these, or you can use an online tool like https://www.epochconverter.com/. It is in millisecond format, e.g. 1491205494000.

    Post the JSON, then post the response you get to /matcher/orderbook on the matcher node. Done! If you post a matching order, it should be Matched in a matter of milliseconds and confirm in under a minute. Pretty impressive!

    If you’re not running your own node, it’s still possible to post orders, but you’ll need a piece of custom code to sign transactions, which you then post to a node. Pblck has created some Python tools to do that — see https://github.com/PyWaves/PyWaves.

  • Waves roadmap 2017

    Waves network has reached a certain degree of maturity, we have around 10k transactions daily, people have created dozens of tokens, mainstream business projects are launching ICO’s, gateways to to the “real” world of fiat currencies are being implemented. I think this is a right moment to formulate our message once again and highlight the directions in which we’re moving.

    Let’s not mince words — we’re a mass adoption coin. Our goal is to take open blockchains mainstream and offer a stable platform for business and community usage. We believe in the legitimacy of open blockchains, they can and will be incorporated in current economical and societal reality, fixing and improving it.

    We work with law firms and regulators to make Waves blockchain a go-to place for business in need of a new layer of transparency and efficiency. A number of directions has been pursued when trying to apply open blockchains to various business areas, but only two use cases truly shine now — it is value transfer on blockchain and crowdfunding/crowdinvesting. Bitcoin itself provided the first truly decentralized way to transfer value, and ICO schemes that emerged within cryptocurrency community are booming now and are about to disrupt the world of venture investing.

    It’s really important to help these fledging opportunities go mainstream. We work with licensed financial companies and regulators to enable fiat transfer on the blockchain. This is a new dimension for cross boarder payments and local transfers, with proper regular oversight it could disrupt the current banking infrastructure.

    Fiat gateways are the entry point from real world into the Waves blockchain. When there you can issue your custom blockchain token literally in two clicks, and you can use it as a CAT, Custom Application Token, as a part of functionality of your application. It might be a gaming app with internal currency, loyalty reward program with bonus tokens, some kind of crypto vouchers… You can also do an ICO, selling your CATs to investors and financing your platform development through the crowdsale. This is a new way to raise funds, and CATs are essentially a new class of securities.

    Securities laws are rather strict across the world, so you need to take special care with compliance here. We’re developing a centralized platform, Tokenomica.com, which is going to work on top of the Waves blockchain, and provide 100% compliant legal framework for different types of token crowdsales, including private equity crowdsales. We’re working with top legal firms on this, and we are pleased with their commitment and interest in this new emerging business. Blockchains are becoming mainstream, and the feedback we get from legal companies is really encouraging.

    To implement so many business features on the blockchain you need to have it ready for scaling and high throughput. We’re moving into that direction too, implementing an approach that allows to efficiently reduce local state storage having thousands of different tokens transferred across the network without a substantial overhead. On top of that we’re implementing throughput scalability approaches that allow to use the system bandwidth more efficiently and potentially can support tens of thousands of transactions per minute.

    To make a blockchain system really flexible and multi-faceted you need to have some kind of smart contract functionality. Current approaches might be great in theory but practically they face lots of issues with scalability and economic incentives. There’s another approach to smart contracts that can be pursued — namely a generalization of non-Turing complete Bitcoin scripting, which allows for all scripts with finite execution times.

    This approach could cover almost all current use cases of smart contracts, and, at the same time, could allow for anonymity implementation similar to Monero. Transaction anonymization is important not only for dark markets but also for legit business, existing in the environment of competition.

    When taken together all these pieces form a holistic picture of a complete environment that covers most of the real world scenarios and in which you can exist without leaving it. Tokens and legality, fiat transfer and smart contracts — you have it all. Our goal is to build and nourish the ecosystem that is going to meet the demand of real world business, robust and compliant.

  • Blockchain trends for 2017

    CoinDesk recently published its 2017 State of Blockchain report, detailing a number of major trends in the blockchain world. As an open, mass-adoption blockchain platform, all of these are relevant to Waves in one way or another. It’s worth a quick summary of the trends identified for 2016, pointing to what CoinDesk expects for the coming year before taking a look at the blockchain landscape from a Waves-centric perspective.

    • Bitcoin’s true volume revealed.Following intervention from the People’s Bank of China, trading fees have been imposed on the major Chinese exchanges. The result is that China now accounts for around 35% of known trading volumes, not the apparent 94%.
    • Enterprise incumbents move on blockchain. Banks and financial organisations, in particular, are starting to deploy enterprise-grade blockchain applications, rather than just proof-of-concepts.
    • Token sales challenge traditional VC investment. 2016 saw a near-static $496 million of VC investment, whilst ICOs are rapidly growing at a total of $236 million (including The DAO).
    • Consortia gain steam. Banking consortium startup R3CEV has released the code for its Corda platform, and Hyperledger has passed 100 members.
    • The push for privacy continues.Monero continues to grow in transaction volumes and market cap, whilst Zcash made an impressive debut before moving into the background.
    • Bitcoin volatility continues. This has been fuelled by scaling concerns as well as geopolitical developments.

    Waves is in a unique position to know what’s going on in the blockchain industry. The platform was conceived of and is being developed in response to known requirements from businesses. Over the past year, we’ve been approached by and worked with many different businesses — partnering with some, advising others, all the time learning where the demand really is, not just where the buzz is among the hard-core crypto crowd. Here’s what we see as the key trends:

    1. Blockchain tokens will go mainstream

    Custom application tokens (CATs, as they’re called on Waves), AppCoins, AppTokens, assets — blockchain tokens are going to be big business. We’re already seeing major applications built on this functionality.

    Tokens are about the simplest blockchain functionality there is: transferring value on the blockchain in the form of a digital asset. What that token represents can be incredibly diverse, since it’s enforced by the application/issuer. It could be a stake in a crowdfunded venture, a fiat-backed blockchain currency, a reward token, equity in a company, fuel for an online platform of one form or another, and much more. But it all starts with the ability to create and send blockchain tokens.

    Platforms that offer what used to be called ‘2.0’ functionality will see increasing use over the coming year. Usability is key here: Waves isn’t the first platform that enables anyone to issue blockchain tokens, but it’s currently the most user-friendly. Both developers/businesses and end users have to be able to engage with these tokens as frictionlessly as possible. Clean, elegant user interfaces; powerful APIs; fast DEXs (decentralised exchanges); low issuance and transaction fees; a high degree of flexibility; massive scalability. In the Darwinian environment of the crypto marketplace, competition is fierce. The platforms that get it right will get the business. We believe Waves is currently leading in this space and stands a strong chance of gaining significant market share as a result.

    2. ICOs will continue to grow

    Powered by accessible blockchain tokens, blockchain-based crowdfunding will go from strength to strength.

    Back in early 2014, the majority of new crypto tokens entailed the launch of a whole new blockchain — essentially, each was a new cryptocurrency coin network. With the advent of 2.0 platforms, it became possible to issue tokens without the technical overhead of bootstrapping yet another blockchain. Now that this technology has come of age, pretty much any enterprise can raise funds by selling a crowdfunding token.

    That makes grassroots investment available to anyone with a convincing pitch. In an era when banks are unwilling to lend, more and more companies and individuals will take up this model. And it won’t just be crypto projects, or even tech companies. Crowdfunding is already a mainstream idea, thanks to Kickstarter and similar platforms. Blockchain just takes it to its logical conclusion by making it a global, low-cost endeavour.

    We’ll see plenty more multi-million ICOs, but also a ‘long tail’ of four-, five- and six-figure projects that will probably account for 80% of the total. It won’t come as any surprise if ICO money eclipses VC investment by the end of the year.

    3. Smart contracts will get street smart, not just college smart

    There’s a lot of hype around smart contracts. Ethereum is gaining mainstream attention and business applications are being built on it. At the same time, the collapse of The DAO last year has raised concerns about the security implications of ‘code as law’. The issue was not that The DAO was hacked, but that a loophole was found, allowing the hacker to exploit its logic. The DAO functioned exactly as programmed.

    Aside from tighter code audits, we’ll see smart contracts gain ground by taking a different approach — still offering extensive functionality and allowing a wide variety of applications to be built, but without the vulnerabilities that come with being so-called Turing complete. There are also scalability issues that need to be solved; having the entire network execute every contract is inefficient. You can read more about Waves’ approach to smart contracts here.

    4. Privacy will go professional

    It’s true that privacy-centric coins have gained a lot of ground, with Monero and Dash posting large increases in market cap and Zcash pioneering a new era of anonymity tech.

    What this high-level trend observation misses is the significance of privacy for institutional blockchain users. The blockchain as implemented by Satoshi Nakamoto is transparent and pseudonymous. There is simply too much information available to casual observers. Whilst personal privacy is an issue that isn’t going to go away, it takes on a whole new level in a business context. Businesses aren’t just unhappy about the transparency of the blockchain: it’s a dealbreaker for many of them. It’s untenable that a financial organisation’s trades could be viewed by anyone, or that financial information mapping a business’s network of employees, customers, suppliers and consultants could be laid bare by an amateur sleuth with no more than an internet connection.

    Alongside blockchain protocols that offer personal privacy, then, we will see enterprise-grade privacy built into blockchain platforms as a matter of necessity.

  • Waves to host open lecture by Vitalik Buterin in Moscow

    Vitalik Buterin, Ethereum and Sasha Ivanov, Waves Platform

    Waves will host an open lecture by Vitalik Buterin, founder of Ethereum, at 19:30 on 11 April 2017 at the Digital October Center in Moscow.

    Vitalik Buterin is the founder of the Ethereum project, an idea for which he won the World Technology Award in 2014 — bypassing Mark Zuckerberg and other contenders. “When Vitalik talks about the blockchain, Stanford professors take out their notebooks and start writing”, as Herman Gref, head of Sberbank, told the forum in Davos.

    Having learned about bitcoin from his father, also a developer, Vitalik decided to create his own blockchain and cryptocurrency. In 2011, Buterin and his friends founded the Bitcoin Magazine. In 2013, the first line of Ethereum was written. Leaving the Canadian University of Waterloo in the same year, Vitalik managed to secure his first grant of $100,000 from the founder of PayPal, Peter Thiel. Ethereum later broke the world record for raising money through crowdfunding, selling 31,000 bitcoins worth of “Ether” ($18.5 million). The platform was launched in 2015 and the market capitalisation of Ethereum is now around $4 billion, while Ether’s cryptocurrency (ETH) ranks second after only bitcoin. On 17 March 2017, the price of Ethereum reached a historic new high against the dollar, hitting $50 on the Poloniex cryptocurrency exchange. To date around 210 startups are already running on Ethereum.

    At the beginning of the event Sasha Ivanov, founder of the Waves Platform, and Maria Popova, curator of the Digital October Center, will give a welcome speech. The meeting with Vitalik Buterin will take the form of an open question-and-answer session.

    The event is hosted by the Waves Platform which, in collaboration with the Digital October Education Center, regularly holds educational courses about blockchain. The next course offered by Sasha Ivanov, founder of the Waves Platform, will be held on April 22 and 23.

  • Waves Launch Decentralized Exchange - DEX 

    Waves Decentralized Exchange and safe trading of blockchain assets.

    We’re launching Waves DEX now, a decentralized solution for digital assets trading. Let’s reiterate why we think that it’s an important development that can actually change things.

    Decentralized blockchain tokens are being traded on very centralized exchanges. Essentially it’s a contradiction in terms, that manifests itself in these exchanges being hacked all the time. You just can’t trust a centralized service with your decentralized tokens. Bitcoin and other crypto is a perfect thing to steal, transactions are non-reversible, transfers are hard to trace. Centralized cryptocurrency exchanges are not sustainable in the long run, since the cost of an successful attack can ruin any successful exchange.

    On the other hand, until we have very high blockchain transactions throughput, we can’t have a comfortable solution for a completely decentralized trading. Putting all trading data on the blockchain is doable, but you have to deal with blockchain latency and tons of data which you have to synchronize over all the nodes.

    There’s a solution in between, and this is the path we have taken — you can do the blockchain settlement but order matching is done in a centralized manner. What does it mean in layman’s terms — there’s a server which matches incoming orders, but has no access to your funds. There’s no chance that you could lose money in this setup, since you have full control over your funds at all times. When the server finds a matching pair it initiates the transfer on the blockchain which moves the funds. The correctness of the matching is verified in a decentralized way, and no funds can be transferred if the orders are not matched properly.

    This is a new approach that can be called “Matching as a service”. You can mount your own Waves matcher and earn commissions. Probably we don’t need to try to decentralize everything at this stage of blockchain protocols development, focusing only on areas where blockchain really improves things considerably. When you need high execution speed centralized solutions work better. Putting the trustless blockchain technology on top you get the best of the two worlds — speed of centralized services combined with blockchain security.
