openANX (OAX) Real World Application of Decentralized Exchanges





  • Introduction to openANX


    The openANX DAO




    At the core of the openANX platform is the Decentralized Autonomous Organization, which is run by smart contracts. The governance model affects the way the DAO behaves, thus always staying in the best interest of all participants.


    Features


    • Risk Transparency

    The ability to assess risk in a quantifiable way is unique to the openANX platform. Gateway tokens can be traded, creating a new dynamic and further increasing transparency.

    • Aggregated Order Books 

    Isolated order books from each asset gateway will be aggregated using the liquidity aggregation system provided by ANX. The end user will have access to a single, seamless order book.


    • Participants 

     openANX takes the strengths of both centralized and decentralized exchanges to create a new middle ground. Addressing the evolving needs of exchanges will attract many participants.

    • Asset Gateways

    In the future, customers will be trading their assets through decentralized trustless exchanges. They will only interact with existing centralized exchanges for onboard and offboarding real world funds; but now the consumer will be protected with blockchain locked collateral and a real-world dispute resolution process.


    • Dispute Resolution

    Disputes can be escalated beyond the asset gateway. An impartial dispute resolution mechanism exists through a third party.




    • Open ANX Foundation

    The Foundation’s objective is to promote the real-world application of the openANX platform. It is a non-profit organization.





    Milestones

    As the project develops, we have a number of key milestones along the way.

    Some More Details About  openANX (OAX)

    The openANX platform will take advantage of technical developments on the Ethereum
    blockchain such as payment channels (Raiden3, 0x, Swap, ERC204) and utilize them to
    overcome the challenges faced by the current CEM. It will co-opt the strengths of the
    existing model to improve the existent decentralized exchange attempts by linking existing
    exchange platforms (“Asset Gateways”) to the infrastructure network and enforcing a
    collateralized deposit system that will provide users with a way to measure risk.

    In addition, by being open source, the project will be transparent and subject to scrutiny and
    input from users and the wider community. In lieu of a centralized authority (government or
    regulator) the only way to enforce transparency is to write it into the blockchain itself.

    By utilizing the latest technological advances and a peer-reviewed and implemented open
    source code, the platform will integrate the strengths of the existing CEM model with the
    best functionality and feature of the decentralized model while circumventing the
    shortcomings of both systems.

    The initiative will offer secondary markets (exchange services) for all forms of Ethereum
    tokens. Ethereum tokens can be in the form of native Ethereum tokens (such as tokens for
    other DAOs), or tokenized representations of off-blockchain assets. Users will be able to
    create an order book and list their token for trading on the openANX decentralized exchange,
    for a token fee and by redeeming OAX tokens for memberships. All off-chain services to the
    DAO will be supplied from competing suppliers.

    The Structure of the New Marketplace 

    Open source, decentralized, transparently governed exchanges will, in our view, eventually dominate the crypto market. With the increasing maturity of the Ethereum Network, Raiden and governance frameworks such as boardroom.to, that vision is now viable. With openANX, we plan to create a truly open source and decentralized platform that uses a hybrid model to integrate the key strengths of the existing CEM with key enhancements such as credit risk assessment, structured dispute resolution and a collateralized deposit system to empower users, providers and third parties to properly evaluate the uncertainty that has long been a part of the marketplace. In this chapter, we will examine the openANX project in detail, the philosophy behind it and how it will aim to address the issues we have discussed. We will also conduct a comparison of existing decentralized exchanges and how the openANX platform will overcome their limitations.


    Why Open Source? 

    The supporters of the project have benefited greatly from the support and advice provided by members of the crypto community, and from this position we would like to give back and support a model that ultimately puts power and transparency back into the hands of the users. We at openANX believe that universal access to a transparent, fair system for the

    trading of digital tokens is an integral step along the road to mass adoption of digital tokens.
    We believe that the benefits of an open source platform not only regarding code, but also in
    relation to suppliers, development, payment gateways and a credit market allow for greater
    viability for a project of this nature. The code persists and can be improved via the
    community long past the dissolution of the original impetus that drove the project’s
    foundation6. As a first step along this path, the Foundation is seeking to raise funds to build
    the first viable, aggregated, open source and decentralized exchange.
    Open sourcing the platform will result in:
    • A decentralized matching engine and P2P facility integrated using an off-chain (e.g.
    Raiden, Swap, or 0x) architecture supporting Ethereum tokens (ERC20)
    • A wide network of suppliers offering services such as development, off blockchain
    gateways for non-native Ethereum tokens (cash and other blockchains), legal
    support for developers, users, and suppliers
    • An Ethereum governance mechanism to approve code changes, selection of
    suppliers and all other aspects of the DAO
    With the recent developments on the Ethereum chain7, the use of ERC20 tokens and the
    use of new payment exchange protocols, we feel the project is now viable.

    The Benefits of Transparency 

    A lack of transparency is a weakness in both the CEM and the decentralized, P2P exchange model. Lack of open source code, questions about fractional reserves, and opaque security protocols have badly damaged the reputation of CEM’s, while on the decentralized side of the equation, limited availability of asset gateway services and low buy/sell order volume are much discussed. In the openANX platform, a key selling point of the project stems from the application of collateralized reserves deposited onto the blockchain by Asset Gateways. Each gateway chooses the level of its deposit and the information is transparent for all users to access. Alongside other assessment parameters, this allows for effective credit risk evaluation.

    The Nature of openANX’s Decentralization

    Previous attempts at decentralization have been unsuccessful because they relied on a
    “barter” system for trading digital tokens, where User A has Bitcoin and User B has
    Ethereum and the two can trade like-for-like, but does not take fiat into account. No existing
    decentralized exchange has managed to attract a sufficient number of new or existing users
    who wish to reflect their trading gains in cash. This limits growth and adoption, which leads
    to low trade volume and liquidity.
    The aim of this paper and the accompanying project are to show one way forward.
    Decentralization is the key driver of this project. The advantages of decentralization are well
    established8: robust systems reduce the chance of downtime, a diverse ecosystem promotes
    competition and transparency, and economies of networks introduce greater liquidity.
    Below is a condensed list of the key issues for existing decentralized models:
    1. Lack of adequate liquidity and market participation, and unacceptably slow trading
    latency and API infrastructure, reducing liquidity from professional traders and
    market makers
    2. No credit market
    3. Lack of lending, borrowing and leverage
    4. Lack of an adequate legal framework and operating model transparency prevents
    risk assessment

    5.Inability to differentiate between the creditworthiness of off-chain Asset Gateways
    6. Lack of efficient integration with the existing legacy financial infrastructure
    7. Centrally managed, closed, source code, data, and/or governance
    8. Absence of backing by a full-scale market operator with the experience in both crypto
    and traditional fiat markets
    9. Minimal or no incentivized support function
    The key issue for most users of current decentralized platforms such as Bitsquare, Bitshare
    and EtherDelta can be summarized in two simple points:
    • Low liquidity means it is impossible to do trades at “volume”, which limits most
    effective trading strategies9
    • One (traditional wire) settlement per trade means it is impossible for some of these
    platforms to attract large players - holders of large asset caches prefer to maximize
    returns by reducing costs for settlement by utilizing large “batch” style payments of a
    single settlement for many trades

    How is openANX different from other decentralized exchanges?

    The openANX project is different from other decentralized exchange initiatives announced
    as it recognizes that non-trading ancillary services are required for attracting the critical
    mass of users required for a functional ecosystem network. Central to openANX is a
    decentralized exchange married to a mechanism that provides transparency as to the
    counterparty credit quality of service provider participants (i.e. Asset Gateways). While price
    discovery and trading transaction execution can be achieved through smart contracts, the
    practical reality is not all trading exchange functionalities can be decentralized, and as these
    services are required in order for an exchange to achieve critical mass the next best solution
    is to provide the means for appropriate risk assessment of these Asset Gateways. By
    making available risk assessment indicators (including but not limited to the posting of
    collateral, membership levels, verified identification information, and other records onto the
    blockchain) and formalizing defined dispute resolution mechanisms (also inserted onto the
    blockchain), participants are provided with transparent access to important information
    needed to evaluate the credit quality of Asset Gateways. Participants are therefore able to
    make optimal decisions with regards to not only trading prices but also the counterparty risk
    they are willing to assume for non-crypto pair trading. These features of openANX enable
    the execution of more than just crypto pair trading and will therefore attract trading
    participants to drive volume, price efficiency and liquidity, which in turn draws other market
    participants who provide additional useful functions to the network economy. These would
    include not only existing centralized exchanges who bring their existing transaction volume,
    but also other participants such as rating agencies who evaluate Asset Gateway
    creditworthiness and credit risk arbitrage traders who effectively provide market pricing.
    The aim of the openANX project is to create a full, autonomous and decentralized exchange,
    using 100% open source code, data and governance. The exchange is to be managed in the
    digital world by a transparent DAO, and in the physical world with the support of a
    transparent non-profit organization.
    What does this mean for users?

    openANX User Journey

    openANX provides:

    •Automatic governance for lending, borrowing, leveraged, and unleveraged exchange
    matching on-chain through open source software
    • The exchange uses “ANX order book aggregation” to pair buy/sell orders across
    multiple order books, joining disparate order books through graph algorithms to
    maximise liquidity
    • A collateral management function allows users to assess the creditworthiness of
    Asset Gateways, with integrated order book support to allowing trading of credit and
    market risks
    • Fast and efficient trading infrastructure as a result of implementing exchange
    matching through payment and exchange channels
    • Handling fiat and other off-chain assets through the use of gateways that must
    provide collateral in on-chain assets in order to issue tokens
    • An open, decentralized system with incentives to suppliers and users to provide
    support
    • “Bootstrap” support by ANX, a sizable trusted market operator with the capability to
    attract market makers for liquidity, develop the open source software, and provide
    minimal viable supplier services in terms of off-chain gateways, KYC services and
    user support
    • Jurisdictional and policy configurations to allow off-chain Asset Gateways to meet
    regulatory obligations and still participate

    What are the benefits of decentralized exchange platforms?

    All cryptocurrency users know the shortcomings of the current centralized exchange model (CEM). Everyone knows about hacks of exchanges, and news of a fresh hack comes along fairly often. Nearly every trader I know has lost some BTC or alt-coins at least once. Does it have to be that way?

    There have been some attempts to improve the system. Exchanges upgrade security, or a decentralized exchange comes along, promising change. This is good. But many of these new projects then suffer their own problems. The news around users of some exchanges not being able to withdraw or deposit funds are common news these days too.

    When we talk about these decentralized exchange platforms like EtherDelta and BitShare, we see they have made some improvements and are great. But they have two new problems.

    First, they don’t have enough users and therefore they lack trade volume and hence liquidity. Go to any one of them and try to buy 10 BTC and see what happens.

    Second, some of these platforms use a model that means “one settlement per trade” This is not ideal for a trader making many trades, or volume players.

    So, the decentralized model is good, but it still has some room for improvement.

    We think the market can’t improve until these problems are addressed.

  • openANX (OAX) FAQ

    • openANX, OAX and the Open ANX Foundation – What is the difference?

      • openANX is the name of the platform and project. It provides advantages such as aggregated order books, transparent collateral and credit risk markets. It is the real-world application of decentralized exchanges.
      • OAX is the name for the ERC20 tokens that are used to participate (eg: to acquire memberships) on the openANX platform
      • Open ANX Foundation is the name of the non-profit organization incorporated in Hong Kong. Its objective is to promote the real-world application of the openANX platform and oversee its initial development.
    • What is a centralized exchange and what advantages/disadvantages does it have?

      • Most existing traditional exchanges today are centralized exchanges, meaning there is a single entity that controls and is responsible for the operation of the exchange.
      • Centralized exchanges have some advantages such as providing critical services, liquidity and banking relationships. However, there are major disadvantages such as a lack of financial and operational transparency, and security concerns as demonstrated by hacked exchanges that resulted in the loss of hundreds of millions of dollars as well as trust and confidence from users and the general public. Trading on centralized exchanges also defeats the purpose of having decentralized currencies (Bitcoin, alternative cryptocurrencies).
      • The term exchange is somewhat misleading in the traditional sense – i.e. on stock exchanges or online marketplace platforms, at the end of a transaction there is the delivery of the purchased goods as well as the transfer of payments. On a crypto centralized “exchange” there is no payment or coin changing hands amongst buyers and sellers (and hence why the transaction is not recorded on the blockchain); rather the transaction is reflected only on the internal accounting records of the exchange and a selling customer that previously was owed coins by the exchange is now owed fiat currency instead. As he still does not hold physical possession, his account is essentially an IOU issued by the exchange to the seller.
    • What are decentralized exchanges (DEX)?

      • Decentralized exchanges are the proposed solution to the problems faced by centralized exchanges and their users. While current decentralized exchanges are a step in the right direction, they often suffer problems such as low volume and liquidity due to the lack of integration of the strengths and key functions of centralized exchanges.
      • DEX do not have integrated banking relationships nor integrated onboard/offboard payment channels, thus fiat trading is not possible on the platform, and it only allows trading of crypto pairs which severely limits trading activity. They are much less practical for users, especially for non-technical users, unless they already have crypto tokens and are not seeking to monetize into fiat.
    • How does openANX differ from other decentralized exchanges (DEX)?

    • Firstly, and most importantly, openANX is complementary to decentralized exchanges. Many Ethereum initiatives such as 0x, RAIDEN, SWAP, will support trustless trading of Ethereum tokens. However, they don’t solve the problem of onboarding and offboarding real world funds. openANX provides an asset gateway mechanism to practically onboard and offboard real world currencies whilst affording consumer greater transparency and increased protection with collateral and a dispute resolution process. The fiat currencies safely tokenized by compatible asset gateways are essentially gateway tokens that can then be traded on other Ethereum decentralized exchanges.
    • High Liquidity

      • Many existing DEX suffer from low trade volumes which leads to low liquidity, partly owing to their “one trade per settlement” model: traders execute one trade and then must wait for the real-world currency settlement before being able to trade again, during which the traders are exposed to counterparty credit and settlement risks. Low volume is also due to lower number of users as decentralized exchanges that use cryptographic tokens only are difficult to enter, due to their inherent lack of fiat gateways. With the provision of a safe tokenization process on openANX, traders will be able to onboard funds and trade multiple times before offboarding; this is crucial for the market makers and arbitrage traders that provide critical levels of liquidity.
      • Additionally, existing centralized and decentralized exchanges operate using fragmented liquidity pools. openANX aggregates the liquidity from each of its asset gateway participants (some of whom are centralized exchanges) to provide increased levels of liquidity. This also lowers the barrier to entry for new asset gateways as they will have access to the overall openANX liquidity pool.
      • Finally, existing DEX fail to adequately provide transparency on the explicit counter party credit risk associated with asset gateways. openANX allows asset gateways tokens to be traded against each other’s, providing a market for credit risk, which results in numerous advantages such as opportunity for hedging credit risk and allowing the explicit pricing of credit risk be to expressed by the market (price discovery).

      Transparency

      • The cryptocurrency community is wary of government regulations (despite the accompanying safety net), yet would still like to have a transparent guarantee of their assets. Existing centralized and decentralized exchanges do not address this need due to their lack of financial or operational transparency. The openANX platform will be open source and governed by a DAO/non-profit “Open ANX Foundation”, and its objective being to promote the real-world application of the openANX platform. Being open source and valuing transparency allows the openANX project to stay true to the movement of decentralization.

      Credit risk

      • On the openANX platform, asset gateways fulfil the role of holding customer funds under custody and issuing gateway tokens on the blockchain. The gateways should still hold the customer funds in segregated accounts, however the gateway can also post locked up collateral on the openANX DAO. This collateral is time locked and made available for dispute resolution. In this fashion, customers have additional, transparent data available to determine the creditworthiness of the gateway (as a function of real world factors and collateral value).
      • Risk assessment is impossible without access to various data about the asset gateway. The exchange models available currently do not provide this information, therefore traders and users cannot price risk. On the openANX platform, the replacement of exchange IOUs with fiat tokens and the availability of information to evaluate risk (collateral, market value of token, credit risk factors etc.) enables traders to start factoring in risk in their trades.
      • Asset gateway tokens can then be traded against each other, with a premium or discount, representing perceived credit risk; this creates a market and price discovery mechanism for credit risk
    • What is an asset gateway?

    • An asset gateway takes off-chain assets from customers, and mints an on-chain ERC20 token equivalent. Amongst other requirements, an asset gateway should:
      • Post some amount of locked collateral into the openANX DAO,
      • Incorporate acceptance of the openANX dispute resolution process into its customer terms and conditions, and
      • Pre-declare its KYC and AML policy and nominate the KYC/AML contract that is used to enforce its regulatory obligations on the blockchain
    • What is the DAO and how does it interact with the openANX platform?

      • DAO stands for “Decentralized Autonomous Organization”, it functions using smart contracts on Ethereum. openANX abides by the DAO, which is governed by the voters on the platform. This is one of the many strengths of the openANX platform – the governance is decentralized and can mould the way the platform behaves and develops.
    • What is an aggregated order book?

      • Current centralized exchanges each have isolated order books that don’t communicate with each other. This creates a problem in that the barrier for entry is high, and it leads to only a few exchanges maintaining and attracting sufficient liquidity to make them financially and operationally viable. Using the liquidity aggregation technology provided by ANX, the openANX platform can aggregate all the order books so the end user can interact with a single, seamless order book that has the combined volume and liquidity from all asset gateways.
    • What is the distinction between the non-profit Open ANX Foundation and ANX International?

      • The Open ANX Foundation and ANX International (“ANX”) are separate entities. ANX will contribute proprietary IP to kick-start the openANX platform. Maintenance and funding for the openANX platform will be performed by the non-profit Open ANX Foundation. After the platform launch, ANX will merely be an asset gateway and supplier on the openANX platform. Other suppliers can be selected by the DAO governance board.
    • What does a gateway token represent?

      • A gateway token represents an obligation of the issuer which users have direct ownership and control of. The market value of these tokens depends on various factors which may determine the perceived risk associated with the gateway issuer, and may include collateral placed, asset gateway reputation, country of issue and KYC processes.
    • What is the credit risk market?

      • The value of different gateway tokens can change, especially if issues arise for an asset gateway. Different asset gateways have gateway tokens that may be perceived by the market as having different risk and hence value. For instance – Acme exchange will issue AcmeUSD tokens as their gateway tokens. The value of AcmeUSD and ANXUSD will be different, as Acme exchange and ANX (as a gateway) will have different risk, which can be priced quantitatively due to the transparent nature of the platform. Note that the function of the gateway tokens is still the same. These tokens can be traded against each other and therefore long risk positions can be closed. This creates a new market dynamic – the credit risk market.



  • Current Secondary Market Structures — Moving from CEM to DEM

    Historical Centralized Exchange Model (CEM)

    The current paradigm of the CEM began with Mt. Gox, and has developed and matured to reach the status quo. The CEM allows companies to provide services for users to buy/sell tokens, or exchange them for other assets through a central gateway platform for a fee. These proceeds ensure the service provider in return offers customer support, security and a suite of product offerings. The strengths of the system have developed over time to coalesce around banking relationships (the ability to turn Bitcoin or ETH into cash) and providing liquidity. However, with repeated security breaches in various exchanges and poor management, public’s faith in the CEM system is increasingly waning. The fundamental question is one of trust — without an effective way to measure risk, users tend to under-price its potential.

    However, there are deeper underlying issues other than security concerns and lack of trust. First among these is a lack of a mature infrastructure, and the system is skewed in its design as it rewards “early adopters”, be it an exchange, an information site or other service provider, making it difficult for interested new entrants to gain access to information which would allow them to objectively assess risk and engage in digital token trading reliably.

    Secondly, and equally important, is the reputational issue . While much of the popularity of digital tokens are due to their decentralized nature, this fragmentation exacerbates many of the CEM’s inherent flaws, such as the lack of regulation and transparency, security risks, possible overcapitalization, and an opacity regarding creditworthiness and credit risk for token holders dealing with these exchanges. These shortcomings are major obstacles in the next development and widespread adoption of the digital token class as a whole.

    In summary, centralized exchanges provide valuable services by acting as asset gateways. It allows the offering of multiple levels of market activities that cannot be matched by decentralized exchanges. However, these strengths are offset by a number of significant weaknesses, including the possibility of substantial financial loss, as well as the reputational damage to the digital tokens ecosystem. Each failure, be it Bitfinex or others, impact all users indirectly and reduced the valuation of the market as a whole, by damaging the credibility of digital tokens as a reliable medium of exchange.

    The key weaknesses in CEM stem from: 1. Custody of customer digital tokens (private keys) 2. Corresponding credit risk to customers upon security or fraud incidents 3. Lack of consumer protection and avenues for dispute resolution 4. Lack of transparency on finances to allow customers to assess credit risk 5. Opaque closed source code and centralized data stores 5.1 Each develops their own exchange, deposit, withdrawal and security software; these are typically not open source (with no or limited audits) 5.2. Metrics and order data within centralised exchanges is not visible to customers, it is unclear to market participants if the reported data is true and complete 6. Fragmented liquidity as the proliferation of exchanges results in separate trading pools

    If we look at the list of the most widely used exchanges, we find that the virtue of market dominance is driven by aggregation and accretion over time, the clear majority of trade volume is handled by a small number of player. Currently, most transactions run through approximately 20 centralised exchanges, with the bulk running through the top nine, namely:

    • Poloniex • Kraken • Bitfinex • Quoine • BTC38 • BTC-e • Bittrex • Coinspot • Bitstamp

    Out of these 9 exchanges, more than half have been hacked and suffered significant financial losses. The common assumption that the larger players should be more resistant to these malicious hacks due to having greater resources and better security has been disproven, as well as the idea that if an exchange keeps a low profile and attempts to tread a “middle path” it may avoid attracting the attention.

    Emergence of the Decentralized Exchange Model (DEM) The shortcomings of centralized exchanges have seen a number of decentralized exchanges emerge. These largely fit into two categories; those that handle native fiat currencies, and those that handle only pure digital tokens.

    A number of pure decentralized digital token exchanges and protocols are starting to emerge, notably on-blockchain markets such as cryptoderivatives.market, and offblockchain protocols such as 0x and Raiden for single blockchain token trading.

    For cross blockchain exchange, the emergence of the Lightning network for cross blockchain atomic swaps is promising.

    These initiatives are becoming broadly accepted by the industry as the likely future of pure native digital currency token trading. Each has benefits and disadvantages, but all lack fiat currency bridging, which is needed to avoid mainstream use of centralized exchanges. The closest fiat currency solution for these exchanges are modelled along the lines of Tether, where each tokenized unit of currency is reportedly held in custody. There is however some level of industry unease with regards to the transparency of data, and consumer protection with these types of solutions. Regardless of industry perception, there is clearly a degree of credit risk for customers of Tether style solutions, with entity, banking, and perhaps sovereign risks with little recourse.

    The lack of convenient and safe fiat currency bridging almost certainly contributes to the lack of liquidity in pure digital token exchanges, in comparison to the incumbent centralized exchanges.

    The other category of decentralized exchanges focus on the fiat currency problem. Various platforms such BitSquare have emerged which support fiat currency and digital token transactions; however, these exchanges have not managed to gain the critical levels of liquidity and trade volumes to supplant the centralised exchanges. The need to perform fiat settlements on a one to one basis to transactions is one reason for this. Highly liquid markets require the presence of market makers and arbitrage traders. These market participants require the ability to trade frequently, with a much higher frequency than that supported by trades linked to legacy financial services payment latencies.

    The challenge then, is to solve the centralization problem while avoiding the pitfalls of existing, decentralized exchanges, such as low liquidity and a lack of choice when it comes to ancillary services.

  • openANX (OAX)  Market Infrastructure

    Market Infrastructure

    The openANX platform will consist of the following market participants:

    • Exchange users

    • Asset Gateways

    • Order book sponsors

    • KYC/AML services

    • Dispute referees

    • Voting members

    openANX Market

    Exchange users are users who wish to participate in the exchange, using the services for native token trading or for real world asset trading. Exchange users of real world assets will require a relationship with an Asset Gateway. In most jurisdictions Asset Gateways are obliged to perform KYC and AML in order to operate legally and maintain the necessary relationships with financial services suppliers such as banks.

    Asset Gateways take into custody real world assets such as EUR or USD fiat and in turn mint ERC20 tokens onto the blockchain. Note that these tokens are not “generic” USD tokens, rather the tokens are specific to the issuing gateway, for example ANX may issue ANXUSD tokens.

    Before receipt of funds and issuance of tokens, most Asset Gateways will first request a KYC/AML service to be performed on any user receiving these real-world assets. This is done by the nomination of a KYC service smart contract address as part of the Asset Gateway registration.

    When a user establishes a relationship with a gateway, the gateway will first direct them to one or more KYC services. The KYC service will provide a KYC rating, which is registered into the openANX DAO. Note that no physical documents or other materials are stored on the blockchain, merely an Ethereum address. The KYC service will stipulate a KYC level, and validity date range through the KYC API.

    Once a user has satisfied the KYC requirements, the gateway can release the token to the user. Gateway tokens generally require one of the following:

    • No KYC at all (tokens can be transferred to or from any valid Ethereum address)

    • Boundary KYC (tokens are can only be minted to, and redeemed from, KYC’d addresses, however minted tokens can be freely transferred between addresses),

    or

    • Full KYC (tokens can only be minted to, redeemed from, transferred, and exchanged with addresses that maintain the stated KYC service approval)

    Asset Gateways will be afforded varying KYC parameters according to their requirements. Many Asset Gateways are expected to register and supply their own KYC service implementation, as in some jurisdictions it is difficult or undesirable to outsource KYC to a third party.

    Where outsourced KYC is possible, significant economies of scale are expected with Asset Gateways sharing KYC/AML service providers.

    When Asset Gateways register for service, they will stipulate the KYC smart contract, KYC level, and token operational rules as per above. They will also pledge native Ethereum collateral onto the blockchain, which will be time locked by the openANX DAO. This collateral serves to protect consumers; it can be released as the resolution of dispute resolution, to users of the gateway in the event of a credit event.

    In the future, the time locked collateral could generate income for the DAO and asset gateways, through powering state channels or staking; however, this is purely speculative at the current time.

    With the availability of transparent, locked collateral, and transparent token issuance, users can form quantifiable views on the creditworthiness of Asset Gateways. Note that the existing best practices are still recommended, i.e. Asset Gateways should hold customer funds in custody, in a non-fractional, audited manner. It does, however, offer a concrete and quantifiable means for users to price the credit risk.

    Credit Risk Markets and Liquidity Aggregation

    Pricing of credit risk is a key activity in any normal financial marketplace. In large institutional trading desks, each deal is broken up into smaller internal constituent deals; which some trading desks focus on pricing the market risk of some assets, whilst other trading desk focus on the credit risk. The profitability of a deal is then attributed to the credit and market risk desks individually.

    The ability to trade credit risk is notably missing from current crypto markets. openANX will support “Credit Risk” order books. In this manner, an ANXUSD token can be traded against another gateway’s tokens (say perhaps AcmeUSD). For example, ANX may have a strong public brand, and high levels of collateral locked up in the DAO relative to issue tokens, whilst Acme has an unknown brand and low levels of collateral. The ANXUSD/AcmeUSD order book allows these two tokens to be traded against other, forming the basis for a credit risk trading market within the crypto marketplace. The pricing of these credit risks further provides users with another objective measure of counterparty risk.

    Order books are opened by the DAO on the request of a sponsoring user. Often the Asset Gateway itself will sponsor an order book for its tokens, for example the ANX gateway would open an ETH/ANXUSD order book.

    With the ability of Asset Gateways to register their tokens and sponsor their own order books, the barriers to entry for gateway operators will be significantly lowered. The introduction of openANX should see many new gateway operators entering the market, with varying levels of credit quality and jurisdictional/asset support.

    Credit risk order books, trading gateway tokens against each other, will greatly improve price discovery to the market.

    This situation by itself is better than the current landscape of centralized exchanges, as there will be greater competition and choice for users, with more transparent credit risk, and collateral pledged on the blockchain to provide a safety net in the event of a credit risk event or dispute.

    It can be argued however that the biggest hurdle to entry for new exchanges is liquidity. Liquidity refers to the amount of traded assets available on the order books of an exchange. A highly liquid exchange could allow a large deal to instantly trade, whilst barely impacting the price. Liquidity has a strong network effect, as soon as one exchange or venue becomes the largest in terms of liquidity, it quickly attracts more liquidity until other exchanges cannot compete. This has arguably resulted in a small group of centralized crypto exchanges dominating the market place for a period of time, until such time as a legal, security, or credit event halts operations.

    openANX overcomes this issue through the application of order book aggregation, coupled with credit risk trading books.

    To consider the situation where there are three order books:

    1. ETH/ANXUSD

    2. ETH/ACMEUSD

    3. ANXUSD/ACMEUSD

    By themselves order books 1 and 2 reflect individual fragmented pools of liquidity. If there is an active credit risk order (i.e. book 3), matching logic call match trades by combining the three order books into a single order book with simple graph.

    In this fashion, an active credit risk order book can transform small individual exchange pools of liquidity into a single large order book. This approach may at last bring about the liquidity network effect to turn a decentralized, open exchange into the dominant source of exchange liquidity.

    The openANX User Journey

    Users on openANX who are seeking to on-board fiat currency to the blockchain will initially require the services of an asset gateway. The availability of public credit risk and collateral metrics should assist users selecting an appropriate gateway.

    The user can be expected to register through online services specific to each gateway, similar to the current situation with centralized exchanges.

    Gateways in most jurisdictions will require some level of KYC and AML; the user will then be directed to such a service, either within the Asset Gateway, or to an external service provider if the Asset Gateway utilizes a third party provider.

    Upon KYC/AML approval (if required by the Asset Gateway) the user may use the payment methods supported by the Asset Gateway to deposit funds. The Asset Gateway will then mint it’s own specific (at least partially collateralized) ERC20 tokens.

    The user will then have the option of trading through a decentralized user interface provided by openANX (i.e. a Mist or Coinbase Token application) or trading their freshly minted token directly with any of the available ERC20 decentralised exchanges.

    It is expected that the user will typically use the openANX trading interface, as the order book aggregation across multiple asset gateway tokens will allow access to a more liquid pool for the conversation of the token into ETH or other major cryptocurrencies available on the platform.

    Eventually the asset gateway token holder can be expected to off-board their tokens back to real world assets. This is conducted by redeeming the token to the asset gateway through the openANX user interface, at which point they would be contacted by their asset gateway.

    User Journey

    Technology Platform

    The technology platform to be delivered by openANX is as follows:

    • A specification of the market operating model as described in the previous section

    • Ethereum smart contracts to govern and operate the market as specified

    • Integration with one or more exchange channels (notably Swap, Raiden, or 0x) to support matching

    • API for each off-chain function integration (gateway, trading, KYC, order book registration, dispute resolution, DAO governance and upgrade)

    • A standard, reference implementation user interface to allow account management and trading (it is expected the community will also provide additional user interface implementations as the platform is entirely open)



  • openANX (OAX) Bounty Program Launch and T-18 Days!





    The weekend was incredibly busy and rewarding for us, with a lot of interest in the Project across social media.

    This was further compounded by the launch of our bounty program over at bitcointalk;

    https://bitcointalk.org/index....

    or you can find the Bounty Program discussed in detail here;

    https://bitcointalk.org/index.php?topic=1947373

    We’ve had emails, calls and messages pouring in over the weekend from people interested in knowing more, getting behind the project, or even wanting to help. We’ve also opened and are running a few thousand people in groups over on WeChat. It’s an exciting time.

    Over the weekend we also sat down with Chandler Guo, a member of the openANX team who is well known in China. We shot some videos, which was made extra difficult by the ever present construction that goes on in Hong Kong, and the fact that Guo 大哥 is a busy, busy man!

    This week we will be launching a number of new languages for the white paper, shooting some videos outlining some aspects of the project in English and Chinese and getting ready for our trip to Chengdu next week, as well as speaking to the media about the project.

    We’ll also be getting some SWAG ready, so look out for t-shirts and stickers!

  • How is openANX Different?

    A lot of the community has asked us to explain the difference between openANX and other decentralized exchanges out in the market, be it BitSquare, BitShare, Bancor, Raid-X, ShapeShift or others. As you can see from even this incomplete list, the move toward DEX’s is significant, and sustained. While I am no expert in all these platforms, I’ve gathered some info to do some initial comparative analysis, and from this, we can draw a few conclusions.

    The first thing to understand is that in any transaction, the Asset Gateway will only hold a single set of keys, rather than both crypto and fiat keys. If a user wishes to move ETH to BTC, then the Gateway will hold BTC keys, if the user is changing crypto to cash, the Gateway will hold the cash. In both the above cases the asset held by the Gateway will be secured by the collateral they have posted to the blockchain(More on this later). At no time will any part of the platform or Gateway service provider hold both keys. This is the critical difference between decentralized and centralized exchanges.

    The three key areas that differentiate openANX for other platforms can be summarized as follows;

    1) Credit Risk markets

    2) Asset Gateways

    3) Liquidity Aggregation

    I’ll spend some time talking through each of these.

    First, I’ll talk about Credit Risk. If you consider the non-crypto financial markets, in most of the large banks and trading houses that run trading desks (who may take long or short positions on various stocks and commodities.) These organizations will have a credit desk, whose job it is to evaluate counterparty risk. The opposite party in every trade or transaction must be considered for its potential to default. By considering available information about the borrower or bond issuer, the credit desk can find an objective measure of the likelihood of default and the potential downside risk. They can only do that by evaluating the other parties assets, liabilities, and other factors.

    This does not exist in the crypto-world. Until openANX. By asking Asset Gateways to post collateral onto the blockchain in ETH and issue fiat tokens for different currencies onto the blockchain rather than simply hold IOU’s, openANX creates an objective yardstick whereby users can compare exchanges by more than just price and volume. By having Gateway A vs. Gateway B USD tokens freely tradable, the reputation and effectiveness of gateways are being evaluated in real-time by the community.

    In essence, this creates new credit markets and new liquidity for participants to trade in.

    To understand the second unique difference of the openANX platform, it is necessary to understand the key complaint about current DEX. Many users talk about the speed and security of these platforms, but lament the lack of liquidity and trade volume. The reason for this is many traders and users like to be able to recognize market gains quickly, and in cash. In the DEX space, very, very few decentralized projects have decided to consider providing Asset Gateway services, and if they do, they provide a single exchange channel, with no competition on rates or fees. OpenANX is a real-world application of DEX technology because we recognize that users want the option to bring assets and cash on and off chain. To provide greater competition, and hence better service for participants, we will bring together existing centralized exchanges via a consortium and allow them to integrate into the openANX ecosystem. Each Asset Gateway will offer a collateralized deposit onto the blockchain, held in a smart contract. The amount of this collateral will be transparent and will allow users to more effectively evaluate the risk of interacting with a particular Gateway.

    By working with existing exchange providers and decentralized platforms to integrate and by migrating the ANXPRO user base to the openANX platform, the openANX platforms enters the market with a ready-made user base. The platform will launch with sufficient users to overcome one of the major challenges facing existing DEX, that of having enough trade volume, or liquidity.

    Many DEX projects contain exceptional technical developments, new specifications or functionality that the wider community greatly anticipates. Many of these projects are developed purely from the perspective on technical excellence, with little actual business understanding by the project team of how to run and exchange, how to build or maintain the network of relationships to be successful in the space. ANX International is the keystone backer of the openANX platform. ANX International runs one of Asia’s oldest exchanges. They are well known in the industry, with a large base of users and contacts in the community. They have a successful business providing blockchain services to companies worldwide, and have one of the largest and most experienced blockchain and DLT development teams in the world. In addition, openANX has a team of advisors who are well known in the industry, from blockchain companies, from the mining consortiums, and from the wider community, from the US, UK, China and elsewhere. By bringing this exceptional team of some of the industries brightest minds together, the openANX project has a wide network of contacts and partners to help drive adoption and growth. This allows for a large and robust network of committed users who will use the platform, exponentially increasing liquidity and hence trade volume.

    Hopefully this post has answered some of the major questions of comparison and outlined openANX’s competitive advantage. For further information,     Bitcointalk ANN: https://bitcointalk.org/index.php?topic=1943946

  • openANX (OAX) Credit Risk and Liquidity




    In the last post, we looked at the example of a user trying to buy a Bitcoin for a certain amount of money and figuring out which Asset Gateway to use. The gist was that one Asset Gateway could offer low credit risk (high collateral levels) for a higher price, while another Asset Gateway could offer high credit risk (low collateral levels) for a lower price, and the user could choose between the two based on their needs and preferences.

    In this post, we will be looking at how this credit risk dynamic could impact other parts of the openANX platform, specifically liquidity. openANX will support “Credit Risk” order books, so that a token can be traded against another gateway’s tokens. Similar to the example above, Gateway A could specialize in trading Token A, with high levels of collateral. Gateway B could trade Token B, with low levels of collateral. The Token A / Token B order book would allow the two tokens to be traded against the other, forming the basis for a credit risk trading market, which is something that is notably missing from current crypto markets.

    Since Asset Gateways in openANX have the ability to register their tokens and sponsor their own order books, it will much easier for gateway operators to join. Even someone with a relatively small amount of assets can become a gateway operator if the person wants to get into that side of the business. As more and more Asset Gateways appear, the market competition will increase, providing better options for users.

    A positive side effect of more Asset Gateways is higher levels of liquidity. Acquiring sufficient levels of liquidity is arguably the toughest challenge for new exchanges. An exchange with high liquidity allows large deals to be traded instantly, whilst barely impacting the price. Without this, large-scale traders won’t be attracted to the new exchange. openANX solves this problem by aggregating its order books, along with credit risk trading books.

    Consider a situation in which there are three order books:

    1. Token A / Token B

    2. Token A / Token C

    3. Token B / Token C

    By themselves, order books 1 and 2 are individual fragmented pools of liquidity. If there is an active credit risk order (i.e. Book 3), matching logic calls match trades by combining the three order books into a single order book with a simple graph. This way, an active credit risk order book can transform small individual exchange pools of liquidity into a single large order book. Order books can be cross currency, allowing the pooling together of liquidity across different sovereign fiat currencies. This approach may finally bring about the liquidity network effect to turn a decentralized, open exchange into the dominant source of exchange liquidity.

    Just as with credit risk and liquidity, many of openANX’s functions are linked. Like gears on a bike, the platform is designed so that when one section works well, it causes a chain reaction and the whole platform runs smoothly.

  • Understanding openANX

    In the last few days to run up, we are getting lots of great questions from the community about the project. As a handy reference, I’ve compiled all our Project Overview videos in one handy post for people to view!



  • openANX (OAX) What does success look like?

    As the team sits here, two hours after project launch, we have sold 18,000,000 OAX tokens.




    9.50 PM Hong Kong Time What a difference 15 minutes makes!

    The team are exhausted but happy. Most of us admit that we cannot remember the last time we have worked this hard for this long.

    Blastoff! -Do these people seem happy?

    The project has consumed the vast majority of our time and resources over the last few months and has taken a life of its own. We all feel a sense of ownership and responsibility. But it isn’t just the project team, its all of the community as well. The users, the backers, the supporters, the tireless hours given by our guys in Russia, China and Korea, the US and a dozen other countries who believe what we are trying to do and see the value of the openANX proposition. It’s a great feeling.

    Look at the video and the picture that accompany this article. These guys all believe very strongly in this project. They have worked hard, stayed late, and delivered. This is what success is. If it comes easy it has no value.

    Tomorrow, we’ll all be back in the office. We’ll be rubbing our tired eyes and getting back to it. We aim to deliver something of value, something cool, and great. We look forward to working with the community that came out to support us.

    Forgive us if we are slightly slower than usual tomorrow, or a little less quick on the uptake. That’s the lack of sleep catching up with us. We’ll be good after the weekend though.

    We’d like to thank all our advisors, Jehan Chu, who has tirelessly supported the project from Day #1, Peter Smith, who saw the value as soon as he understood the potential of the project, and Chandler Guo, who without his help we could not have succeeded in China.
