Innovative All-in-one Cryptocurrency Apollo DEX Exchange Enters Beta with 100% Private Transactions and Atomic Swaps Enabled

October 2019, Vernon, Missouri – Last year the idea of 2-second fully confirmed blockchain transactions, an adaptive forging system with transaction-only block creation seemed like a long way away. However  All-in-one cryptocurrency Apollo Blockchain has achieved this feat in less than a year. Add to that unlimited scalability, a well-designed cure for blockchain sustainability, (database sharding), and another revolutionary technological leap known as Atomic swaps, and you have one of the most promising new cryptocurrencies in the world today. Having started close to two years ago, Apollo already possesses many of the attributes that investors have been looking for, not to mention the technological improvements and solutions the industry has been tirelessly working towards. Apollo DEX Individuals who feel that they may have missed the beginning of a true blockchain space revolution could be forgiven. However,  Apollo Foundation has just moved its DEX featuring an Atomic swap technological solution to a Beta stage and it has no central governing entity, which means that assets are not controllable by anyone except their rightful owner. Steve McCullah, Apollo’s director of business development stated: “Apollo DEX is one of the safest ways on Earth to trade crypto. Unlike nearly all ‘decentralized’ exchange platforms that still can freeze assets, take funds and implement KYC, the Apollo DEX has no governing entity. Trades are accomplished through atomic swaps and do not require a central entity. The Apollo Foundation does not keep it running, regulate it, control it or profit from it in any way. Apollo DEX is hosted and powered by its users, designed by its users and only its users (forgers) will profit.” While lots of projects have Napoleonic plans to disrupt the industry and spend years on creating concepts, the Apollo team has already deployed many of the things that until now were just considered theories. The DEX is already in Beta stage, as the team has decided to test drive their product in a real-life condition, once again leading the progress of the industry. Apollo Foundation in 2020 The “fastest” – doesn’t mean that it is as fast as it could be. That seems to be the general feeling at Apollo HQ at least before announcing their work on ARK consensus with an estimated 1 MILLION + TPS. Steve McCullah, director of business development, describes the ambitious nature of Apollos 2020 vision, stating: “Apollo’s 2020 vision is to become a next-generation, post-blockchain cryptocurrency. We’re architecting a post-blockchain distributed ledger technology (DLT) based on the advanced principles of DAG (directed acyclic graph) consensus,” Steve Continues:  “This technology will put Apollo’s features above the competition. With an expected TPS (transactions per second) of at least one million, Apollo will offer capabilities surpassing anything on the market today.” Apollo strategy for 2020 features also building a decentralized ecosystem of connected products and technologies that will be operated through Apollo blockchain and APL Coin: – Apollo Cloud – DEX production release – ARKNet (an infrastructure for decentralized applications What is even more important, the team understands the necessity of building trust and adoption along with technology. Between plans for the most powerful decentralized application infrastructure (a decentralized Internet) and the only decentralized file storage service with reasonable fees and no limitations a file size, Apollo’s vision does not disappoint and their past accomplishments certainly suggest that its team has the experience necessary to pull it all off. National Currency Initiative Apollo Blockchain has an unwavering focus on achieving true mass adoption via its Mass adoption initiative. The initial target is the continent of Africa, where the foundation has partnered with the ADF group to pitch to all 54 nations on the continent of 1.2 billion. The Apollo team is currently in discussions with the governments of at least three nations and has multiple “Apollo Banks” already open. On top of this foundation is developing tools for mass adoption, including a lite wallet app. The mobile app will have a QR code, as well as merchant features. This will help Apollo to gain merchant adoption globally. Apollo Coin the main currency of the blockchain already shows reliable growth liquidity and can be purchased at Bitmart and IDAX. The team’s approach stands for the development of the complete infrastructure which makes APL a good asset to hold and use shortly. That is what happens when the passion to create and professional approach to meet each other in one team.

Cryptocurrency Apollo DEX Exchange Innovates with New Transactional Packages

All in one Cryptocurrency Apollo Blockchain proves its mettle once again, as it enters Beta with 100% private transactions and a whole new DEX. Major Game Changer Evolution in the blockchain sector seems a wild goose chase, as major players doubted the possibility of a two-second fully confirmed blockchain transaction, and adaptive forging system with transaction-only block creation until the Apollo Blockchain achieved this feat in a major technological breakthrough. The Apollo revolution also stretches to the good design cure for blockchain sustainability, unlimited scalability, Atomic swap and other major firsts in the blockchain industry. Although still relatively young, Apollo has proven over its two years of existence that it is capable of solving the major problems bedeviling the blockchain sector, as it has taken on and surmounted several challenges facing major investors in the industry. Apollo DEX Security is one of the major features of the new Apollo Cryptocurrency, and with its whole new features, users can be well assured of the safety of their data. The Apollo Foundation has just moved its DEX featuring an Atomic swap technological solution, which possesses no central governing entity. This means that the assets in the system are not controllable by anyone except the rightful owner, who thus determines who has access to it or not. Commenting on the security measures put in place by Apollo to safeguard the platform, the director of business development Steve McCullah stated that: ‘’ Apollo DEX is one of the safest ways on earth to trade cryptocurrency. Unlike nearly all other decentralized exchange platforms that still can freeze assets, take funds and implement KYC, the Apollo DEX has no governing entity.’’ Revolutionary Method Major platforms in the Blockchain sector mostly rely on outdated methods to combat 21st-century challenges, which is a major bottleneck facing the industry. But the Apollo team has already deployed many of the things that until now were just considered nothing but mere theories. The DEX is already in the Beta stage, as a team is already in place to test drive their product in a real-life condition. “The Apollo platform is not just breaking new grounds in the sector, but also setting an unprecedented standard in the industry. The platform’s 2020 vision is to become the next-generation post-blockchain cryptocurrency, by architecting a post-blockchain distributed ledger technology based on the advanced principles of DAG (directed acyclic graph) consensus.’’ Learn more about Apollo Coin- http://apollocurrency.com/en/ Find Apollo on Facebook- http://www.facebook.com/Apolloprivacycoin Follow Apollo on Twitter- http://twitter.com/ApolloCurrency Apollo Coin on Github- http://bit.ly/aplpubgit Join Apollo Coin on Instagram- http://www.instagram.com/apollocurrency/?hl=en Media Contact Details Contact Name- Tim Vuychik Email- General@cryptoagents.pro Disclosure/Disclaimer: This press release is sponsored and produced by a third-party source and should not be viewed as an endorsement by ZyCrypto.

MOV: A Next-Gen Decentralized Cross-chain Layer 2 Value Exchange Protocol

1. MOV Protocol 1.1 Technical Framework MOV is a next-generation decentralized cross-chain Layer 2 value exchange protocol based on Bystack’s mainchain-sidechain architecture. Consisting 3 core modules: Value Exchange Engine Magnetic Contract (Magnet), Decentered Cross-Chain Gateway (OFMF) and Layer 2 High-speed Sidechain (Vapor), MOV is dedicated to building a heterogeneous value asset exchange and collaboration ecosystem. The successful release of Bystack laid the foundation and product form of the MOV protocol and constructed a self-sustainable ecology while expanding the boundaries of assets of Bytom. And MOV will be more committed to an open and exogenous ecosystem, nourishing more mainstream asset dimensions and the formation of other ecosystems based on Bystack, establishing a value exchange matrix on multiple dimensions. Figure 1 Internal and External Ecosystem of Bystack & MOV The mainchain-sidechain architecture is commonly seen in hierarchical systems. For example, Plasma chooses one mainchain and multiple sidechains for the mainchain scaling based on the mainchain mortgage. Mainchain and sidechain are logical distinction. Mainchain, while working as a public blockchain, can be used as a platform for mapping assets on sidechain and transaction collaboration. The mainchain-sidechain logic is a reasonable business architecture design, giving more freedom and space for value exchange collaborations. At present, gateway and sidechain-relay take the center stage of cross-chain solution while Hash-Locking is generally used to construct atomic swap in payment channels. Polkadot and Cosmos, the most famous projects in terms of sidechain-relay, are based on PoS governance. They will dominate themselves in cross-chain collaboration scenarios and have their own standard framework in development, SDK and cross-chain communication protocol. With native economic model and tokens, they aim to solve the evil-doing and incentive problems in cross-chain collaboration. Such heavy model scheme will face complex governance issues such as judging good and malicious nodes. The fluctuation of governance will affect the efficiency of cross-chain collaboration, so it is not conducive to the establishment of their respective cross-chain ecosystems in the initial stage. In addition, the sidechain relay protocol based on smart contract is not suitable for accessing the final public blockchain (such as bitcoin), which will lead to cross-chain transaction confirmation and affect user experience. This model will also face high maintenance cost like data availability and assets expansion. The gateway mechanism is an efficient and practical mechanism that has been verified by the actual scene. The gateway plays an important role in establishing cross-chain trust endorsement, unifying cross-chain communication protocol and coordinating mainchain-sidechain transaction confirmation. In real-life scenario, cross-chain gateways will face the drawbacks of centralized operation, which leads to trust issue among cross-chain collaborations and low interoperability, which in turn affects the expansion of traffic, applications and developer ecology. Thus, creating an open low-cost standardized decentralized cross-chain gateway mechanism has become more important than ever. There is a decentralized open gateway design in the framework of MOV protocol, which effectively solves the problem of trustless hosting and standardized access of mainstream assets in traditional cross-chain gateways, and provides efficient interoperability and traffic protocol for the cross-chain collaboration ecology of diverse assets. As the core platform of value exchange, Vapor sidechain offers customized native magnet contract engine and decentralized oracle based on its own BUTXO model, breaking the asset-mapping-only boundary in traditional cross-chain models, establishing reasonable collaboration scenario of multiple asset value exchange. Compared to the current one-to-one matching model of the traditional decentralized exchange DEX (Decentralized Exchange), the magnetic contract can form a portfolio exchange model based on the BUTXO multi-asset atom exchange feature. 1.2 Ecosystem Whether it is a single DEX or a single cross-chain facility, it can only gather participants and liquidity facilities within its sphere of influence. Due to the isolation of communities, differences in infrastructure and economic models, it is impossible to build a comprehensive multi-asset value exchange market. DEX is unable to obtain liquidity support from the underlying chain and cross-chain ecology. A single cross-chain ecosystem often lacks or cannot take into account the influential liquidity conversion medium represented by market makers and DEX. However, forcing the integration of these existing facilities often results in the system not being able to operate continuously due to the irrational participants roles and the differences in economic models. The new portfolio exchange architecture gives birth to new species and ecosystems. A prosperous value exchange ecosystem needs to have sound participation designations that can propel each other so that the entire economic system can be self-consistent and self-circulating. A superior technical framework allows all roles to perform their duties, reducing friction and adding value. Figure 2 Ecosystem Flow Chart MOV is open to a variety of proactive participants, such as Maker/Taker to Wallet/Exchange. These enormous and fragmented free participants form the core driving force of the ecosystem through a variety of native service frameworks (Magnet, Blockmeta, Byone, Bycoin), performing seamless interoperability with low friction and continuously contributing to its liquidity value while enjoying a convenient exchange experience. These liquidity accumulations and premiums can further back-feed and support ecosystem infrastructure builders (Vapor and Federation nodes) to complete economic replenishment and value-added efficiency. 1.3 Advantages and Features Trader friendly. By meeting the mainstream value exchange requirements in terms of asset diversity and liquidity, MOV is superior to the existing exchange market in terms of user habits, transaction fees and user portals. The system provides arbitrage mechanism and multiple transaction strategies, thus affecting user asset storage habits such as transfer as transaction, safe to deposit and easy to trade. Friendly to the public blockchain within the system. As an open ecosystem, the trustless and standardized gateways will greatly simplify the consensus cost and technology access costs of cross-chain collaboration, and back-feeding the public blockchain’s own asset flows and user traffic. This is a self-consistent ecology that aggregates the major players in the current blockchain industry through decentralized value exchange, including traders, wallet providers, digital asset custodians, public blockchain projects, liquidity providers, derivatives developers and DeFi developers etc. There may be diverse needs, such as privacy protection, onchain credit, onchain oracles, etc. Integration and support for these infrastructures will bring traders and project parties great convenience and attraction. 2. Open gateway OFMF 2.1 Open cross-chain gateway design elements A complete cross-chain mechanism will form a good network effect and interoperability, making the integration and collaboration of diverse assets more borderless and seamless. It is a key entry point for a complex heterogeneous ecosystem, thus constructing a reasonable open cross-chain gateway protocol is a key part of the overall framework. The core element of the cross-chain gateway is to establish a decentralized federal gateway, which means that the key ecological participants will form an alliance network driven by a reasonable economic model and business with reliable security, flexible management and decentralized power. Federation custodians is open to free election and economic governance (with the help of the node plan of the public blockchain’s own ecology), establishing a complete identity verification and reputation risk assessment mechanism. The change of custodians and incentive mechanisms must be completed under a transparent governance consensus models with a sound replacement design. Federal gateway should be decoupled from sidechain consensus nodes to avoid extreme situations where sidechains collectively do evil. Decoupled architecture facilitates sidechain changes and multi-asset extensions. The roles of federation include Federal Custodian and Data Availability Service Provider: (1) Federal Custodian: the manager of diverse cross-chain assets, the manager and executor of multi-signature authority, core role of the federation trustless mechanism; (2) Data availability service provider: Provides data for federal custodians, collects, verifies and maintains legal cross-chain transaction information and events from the mainchain and sidechains, and provides multi-chain light node block header synchronization services (block headers include StateRoot for cross-chain trading status to verifier information, which can be used to verify transaction combined with Merkle proof of cross-chain trading). (Federation governance consensus network. Taking into account of the clear definition and guarantee of separation of authority and responsibility of the federal node, signature cooperation, gateway governance, exchange rate adjustment and other operations need to be processed through the governance consensus network to ensure the transparency and efficiency of collaboration of federal nodes.) Both of them acted as trust messengers and data messengers in a complete cross-chain collaboration. The rationality of their design is directly related to the completeness and standardization of a cross-chain gateway mechanism. A protocol or algorithm that is easy to obtain a standardized consensus is particularly important for the ecological development of blockchain, just like DeFi. Data availability service providers are responsible for maintaining cross-chain data availability and even providing evidence of frauds. They export sound data services to federal nodes and assist federal nodes to handle cross-chain transactions securely and efficiently. Different federal nodes have the right to verify the authenticity and legitimacy of the cross-chain transaction through the synchronized block header information. After the verification, the federal nodes will cooperate to process the corresponding sidechain minting and mainchain withdrawal. To reach the threshold of co-management rights while monitoring the status receipt, data service provider record the merkle tree of the complete operation cycle and the cross-chain transaction. The following is a schematic diagram of the process of transferring assets between the Bytom mainchain and the Vapor sidechain through the two roles of the Federation. Figure 3 Federation Workflow Chart In addition, in a general open architecture, there are often sidechains with weak governance and asset values, which will be subject to the extreme cases like the collective malicious verifier. Such cases will affect the trust of the overall network. The role of Ranger could be introduced to prevent fraudulent certification. The Rangers are freely distributed in the network. They can secretly monitor or supervise randomly and periodically and get reward by cracking frauds. As ranger can require re-examination of the block, in order to prevent them from doing evil and dust attacks, a certain deposit must be pledged before each block re-verification is initiated. If the gateway proves that the evidence is not true, the deposit will be confiscated. The sidechain is often accompanied by the operation of withdrawing or transferring assets on the mainchain. A dispute period (challenge period) could be introduced plus the third-party supervision mechanism so that large-value transaction could be monitored and secured. The initiator of the transfer operation needs to submit deposit. If there is no objection from the ranger during the dispute period, the transfer operation will be completed after the dispute period. If the ranger submits a valid dispute evidence, the transfer will be terminated and initiator will lose the deposit. Therefore, for those sidechains with weak governance structure, the ranger mechanism deserves serious consideration. The ranger needs to maintain complete blockchain data, monitor the generation of sidechain blocks and check the validity. It can be regarded as the upgrade version of the data availability service provider. Cross-chain will bring better blockchain interoperability and network effects, guiding the major public blockchains to follow a more uniform protocol standard, which is possible to give birth to a common attribute protocol layer architecture. Therefore, a complete open gateway-based cross-chain protocol generally needs to meet the following four design elements: (1) Decentralized governance of the gateway, that is, trustless cross-chain and asset custody; (2) Verification of the authenticity of the cross-chain event, verifying the existence and confirmation of the cross-chain transaction by maintaining the light node synchronization block header; (3) Uniform cross-chain protocol data format to ensure the atomicity and security of the entire crosschain router; (4) Validity proof of cross-chain message, through the supervision mechanism such as ranger to prevent malicious events. 2.2 Open gateway management framework OFMF Based on the core elements mentioned above, MOV proposes a practical collaboration framework, the Open Federation Management Framework (OFMF) which further divides Federation into three modules: cross-chain minting/burning, federal management and mainchain-sidechain communication: (1) Cross-chain minting/burning module: The minting process connect other mainchain through standard protocol. When the mainchain transfers assets to the gateway, it creates corresponding assets on the Bytom mainchain and passes it to the Vapor sidechain through the gateway again. The burning process is reversed cycle; (2) Federal management module: decentralized cross-chain asset co-hosting, managing the generation, storage and signing of multi-signature private keys, and coordinating between federal nodes; (3) Mainchain-sidechain communication module: monitors cross-chain transactions between the mainchain and the sidechain for authenticity verification. Figure 4 OFMF Modules OFMF defines an open universal cross-chain protocol format, which is friendly to mainstream public blockchain, ensuring the security and atomicity of the entire cross-chain message routing, owning a complete governance structure and trust mechanism with integrated hot-cold and multisig custody system. Any other public blockchain ecosystem can independently access the interoperable network system in accordance with open protocol standards and access mechanisms. OFMF is based on one mainchain and one sidechain hierarchical structure: firstly deal with the cross-chain transactions between the public blockchain and the Bytom mainchain, then map other public blockchain assets on the Bytom mainchain. After that, OFMF will handle the cross-chain interaction between the Bytom mainchain and the Vapor sidechain, setting up different logical sub-gateways through hierarchical mechanism, managing assets from different public blockchain, and define unique sidechain assets through the Bytom mainchain protocol. Figure 5 OFMF Workflow Chart Such architecture is friendly to the Vapor sidechain, which does not require attention to other public blockchains, and only interacts and reconciles with the Bytom mainchain, helping Vapor to focus on the value exchange on a larger scale. Although this framework will have a “multilateral” pattern and introduce additional routing, OFMF’s efficient and low-cost underlying mechanism based on Bytom will make the intermediate links smoother and more seamless. 2.3 Federation Management Module At the core of the OFMF management architecture lies the construction of a trustless asset management system. A new joint asset escrow model or collaborative service brought about by the gradual booming cross-chain asset collaboration needs. Therefore the wallet provider and professional digital assets custodians are the major roles in the federal nodes plan. The Federal Node Campaign will set up open and transparent access and exit rules to disclose necessary certification qualifications and risk solvency abilities. At the same time, OFMF provides a professional decentralized gateway collaborative hosting service module to build  a secure distributed cross-chain asset management system with the federal nodes. Figure 6 Federation Management Modules The Federal Management Module expects to reduce the manual operation of OFMF, further reducing system risk, improving system operation transparency, introducing professional and mature asset custody and cryptography mechanisms, establishing multi-level signature nesting and combination system, so that power can be easily distributed and scaled.  Thanks to the practical application of the mature multi-sign and small-range threshold signature mechanism in the mainstream blockchain system, the federal nodes are responsible for different private and private key shares, running their respective nodes, in the threshold signature synchronization network and the multi-signal asynchronous network. By co-signing the transaction and multisig authenticity, the centralized power risk can be further prevented. Manual audit is reserved as the final step on the basis of automated collaboration. Figure 7 Schematic Diagram of Multi-level key Management Mechanism The whole set of collaborative hosting services consists of key management server, signature collaboration network, risk control model strategy, cross-chain interaction adaptation module, node management module, proxy service and open SDK/REST API: (1) Key management server: It is mainly used for confidential operations such as collaborative generation, distribution, management, storage and signature of multi-sign and threshold signature keys. By setting up a private key proxy server and coordinating with the risk control strategy, confidential operations and private keys are detached from public network. The introduction of mature programmatic information management system could further ensure the security of federal node confidential information; (2) Threshold network module: establishes a signature cooperative network between federal nodes through message queue and permission mechanism, which is a small and secure consensus network system; (3) Cross-chain adaptation module: adapts extension of multiple currencies, be compatible with the traffic portal that has the mainstream cross-chain facilities, and connects the data service to verify signed transaction; (4) Node management module: responsible for the replacement of federal nodes, executing the economic model, providing services such as node program health detection, behavior record confirmation, and message notification; (5) Risk control model: base on the mature managed risk control strategy, 24-7 maintenance and monitoring and event recording to achieve separation of asset management and operation and maintenance. Guarantee digital asset security by restricting access to IP, API access control, limit speed limit, black and white list, multiple authentication, etc. It also provides more advanced risk control measures such as HSM encryption, fund collection algorithm, hot and cold separation, configuration key weight, and time control. Custody systems are automatically adjusted for risk control to balance ease of use and security. Different combinations of access factors are set up according to different levels of risk, and the intrusion detection and prevention system detects suspicious activity and blocks potential intrusions. In addition, for a professional node partner who is a professional hosting service provider, an insurance mechanism for pre-allocating the reserve pool can be established under a certain circumstance. If an unfortunate security incident occurs, the reserve pool will be used to cover user’s loss. 3. Magnet Contract 3.1 Vapor Pro To support the new Bystack architecture and MOV protocol, Vapor will be fully upgraded to Vapor Pro: integrated support for magnet contracts based on the BUTXO model, building a new open contract verification consensus, introducing pluggable module design, and providing onchain oracles. Magnet contract Bytom’s unique BUTXO model interprets the nature of Transaction, which is the atomic  exchange between different assets. The magnet contract further expands the capability and standardizes contracts of BUTXO’s asset exchange.  The matrix trading pair model is introduced so that matrix swapping could be completed with just one transaction, making multi-asset matching discovery and atomic swapping easier to achieve, empowering efficient exchange engine support at the core level of MOV.  However, there are still several aspects that needs improvement: (1) Add a magnet contract template to simplify onchain transaction, mitigating blockchain size concern; (2) Create a parsing library for the template, which facilitates the contract module, wallet module, and kernel module to expand/data read/parse the contract; (3) Modify the consensus module, call the contract module to perform magnetic matching before signing blocks, and the matching rule is written into the consensus; (4) Modify mempool module of the kernel to list the transactions that are not self-packaged as dust transactions; (5) UTXO module of wallet layer: records the UTXO information of pending order that are related to wallet itself and provides query support for all transactions. Figure 8 Magnet Contract State Transition Diagram Open contract verification consensus Upgrading the existing Vapor state machine consensus, natively supporting the magnetic contract algorithm rules, allowing all consensus node to participate in the block generation and the verification match of the contract transaction. Pluggable module design The decentralized value exchange protocol module is a “secondary module” that has a database, business logic, and interaction with the chain kernel through external interfaces. The secondary module does not affect any consensus logic of the mainchain kernel, but if the kernel is bundled with a secondary module, the kernel passes the block/transaction data to the secondary module for data validation or status update before and after completing some of the specified behaviors. By embedding multiple secondary modules in the kernel, sidechains enable pluggable DEX modules, virtual machine modules, or other enterprise-level custom business modules. Onchain Oracle Based on self-consistent and self-driven onchain-based value exchange ecological parameters and data, MOV’s own decentralized financial oracle can be formed. The input, transformation and output of data are completely operated onchain, providing safe and reliable data service for community expansion and DeFi application prosperity. 3.2 Magnet Contract The magnetic contract module (Magnet) is the core engine of the entire decentralized value exchange protocol. It is mainly responsible for two things: the first is to transfer the matchable UTXO to the chain kernel layer into for block generation; the second is to verify whether the matching logic of the transactions in the block meets the matching rule when verifying the block, and prevent the consensus node from doing evil in the matching process due to the conflict of interest. Both of the user’s pending orders and transaction matching are onchain contract behaviors. Since Bystack is a one mainchain multiple sidechain model, the contract engine module will be combined with Vapor as a pluggable module and activated through softfork or voting. The contract engine module needs to have the following general interfaces: ChainStatus: to interact with the kernel to indicate its own data state, to ensure data consistency between the kernel and the secondary module ValidateBlocks: to verify if the matching logic in one or more continuous block meets Magnet’s secondary consensus rules ValidateTxs: to verify if one or more transactions meet the second consensus rule of the Magnet module ApplyBlocks: to update the trading data of the Magnet module by parsing the block transaction data DetachBlocks: to update the transaction data of the Magnet module by rolling back block transaction data BeforeProposalBlock: to generate contract transactions and add to mempool before the consensus node generate block. The core database module is added to store all pending contract transaction pairs to support the query requirements when matching transactions. The database needs to implement three functions: Feedback on the types of all asset trading pairs Add/delete/update trade pair information Return all transaction pairs for the two specified assets (in ascending order) There are two data sources for the magnetic contract when matching transaction pair: the first data source is the core database, which provides support of historical data; the second data source is the in-memory transaction pair, which provides data support of onchain transaction verification or block rollback. Orderbook contract design, pending order trading contract is a premium version of coin-to-coin trading contract. The essence of the contract is to lock any number of assets A to exchange assets B at a specific exchange rate. There should be four constants stored inside the contract: the ID of the asset B, the exchange rate, the public key of the pending order user, and the address of the pending user for receving asset B. The contract can be solved in three modes: All resolved: All assets in the contract A are converted into assets B and transferred to the address of the pending order user Partial resolution: Part of the asset A in the contract is converted into asset B and transferred to the address of the pending order user. The remaining assets A are re-locked back to the contract itself (the newly generated UTXO) through the recursive contract model. Cancel pending order: The pending order user transfers the asset A in the contract back to his own address by private key signature. Support professional trading strategies: limit order, advanced limit order (real-time transaction residual cancellation, full transaction or cancellation), market price order (the best price of the counterparty, the best price of oneself, the best five-level real-time transaction remaining cancellation) and plan order, etc. Finally, there are questions about transaction fees and avoiding dust attacks: Since all trade pairs are stored on hard drive, the junk transaction pair does not run out of memory, but it will take up too much hard drive space. If there is a serious problem, you can set a consensus in the Magnet module to require a small amount of BTM fee for each pending order transaction. Contract will be inflated if it must complete the trading fee charging. You can consider setting each of the consensus nodes to set their own matching interest rate. When the consensus node matches a trade, if the interest rate is less than one thousandth after the match, the match is abandoned. The most obvious attack vector of Vapor is the zero transaction fee setting. Malicious attacks are mostly based on this. 4. Ecological Economic Model 4.1 Participants In the overall ecology of MOV, six major participating roles have been clearly defined in terms of efficient value exchange. Their respective responsibilities and ecological positions have been defined. Multiple economic sources such as basic income and value-added distribution have been granted to ensure normal operation of the trading system and participant enthusiasm in the early and late stages of the ecology. These six roles are Federation Custodian, Depositor (Staker), Trader, Voter, Consensus node (BPer), and Asset Application Operator (OPer): 4.2 Ecological Incentive and Closed Loop The MOV ecosystem contains self-sufficient incentive mechanism. With clear economic input and economic output for each participant and a dynamic balance of cost and benefit ratios at different stages of development, the six roles closely work together to form a complete ecological community. Incentive for Federal Custodian Federal Custodians Open Plan – Federal custodians will be open for recruitment. Managers who become federal custodians need to have rich asset management experience, strong technical development capabilities and good branding influence. Reward Mechanism – Earn a certain amount of fees and staking rewards by providing excellent cross-chain trading services and asset custody services. Exit mechanism – Malicious custodians will be ordered to exit, or the federal node will be removed from the federal node after requesting to quit. Incentive of BPer Inheriting from the election rules and incentives of the Bystack protocol, BPer are in good operation with the official launch of the Vapor sidechain. The development of the MOV ecology will further enrich the incentive source of the consensus node. In the previous design, the incentive of the consensus node mainly come from the block reward of the sidechain. In the MOV ecology, the incentive of the consensus node comes from three parts: firstly the block reward of sidechain, secondly a share of the transaction fee, and finally the price spread of matching trades. More incentive source will attract more institutions to participate in the consensus node campaign, and thus expand the influence and competitiveness of the ecology. The exit mechanism of the consensus node is unchanged. Incentives for stakers, traders and voters The incentives of the stakers are derived from the minting incentives. At the initial start-up phase, stakers are encouraged to lock multiple assets, which will be converted into staking hashrate according to a certain exchange rate. The stakers will get minting reward accordingly. The incentives of the trader are derived from the promotion reserves. At the initial stage, traders are encouraged to trade and use exchange contract. The incentives for voters are derived from consensus rewards, which are consistent with current incentive rules. 5. Summary In summary, the centralized exchange has a single point of failure and the Achilles’ heel of asset security. In contrast, decentralized exchange DEX has a higher level of security: even if hacked, the user’s assets are still in their own wallet; there is no risk of self-stealing, no bankruptcy of the exchange. However, at present, decentralized transactions also have low efficiency in onchain transactions, onchain settlement, offchain matching and centralized third-party, etc. Bytom team release the next-generation decentralized cross-chain Layer 2 value exchange protocol based on the BUTXO architecture. By proposing the innovative idea of “transfer to trade and matching as smart contract”, Bytom will fundamentally subvert the definition of traditional DEX, and then blur the following boundaries. Firstly the boundary between the exchange and the wallet. The wallet is the trading exchange, there is no third party to match orders. The second is the boundary between the OTC and Exchange. The wallet is the combination of both. The third is the boundary between trading and transfers. The transfer is just a transaction of the designated counterparty. It is a specific transaction. The so-called trading is a transfer action that does not specify the counterparty. It is a BUTXO of token-to-token swap. The so-called market order is simply a special transaction that does not specify a counterparty and a transaction price. Trading logic is nothing more than three major variables – counterparty, trading price, trading time. MOV will provide SDK for each module, offering flexible and high-speed magnet contract template with different trading variables, thus meeting DeFi’s diverse and high-level business needs. Meanwhile the system also opens its mature middleware services, especially for developers and operators in the field of liquidity, open quantitative strategy support, market maker APIs and composite interfaces to encourage the creation and enrichment of DeFi in a fair and open onchain value exchange market.

Can Atomic Swaps Reach Critical Mass?

Atomic swaps are one of the most promising advances in decentralized technology: they’re a trustless method for peer to peer trading, without relying on a third party. These swaps rely on Hash Time-Locked Contracts, or HTLCs, which automatically execute or cancel a trade after a certain time limit. This ensures that neither side can default on the deal. Although the full details are more complicated, atomic swaps simplify crypto trading in some very important ways. Unlike traditional centralized exchanges, these swaps don’t require a third-party custodian, and unlike most decentralized exchanges, they don’t rely on relayers. Instead, cryptographic proofs power the entire transaction. This approach to trading is also lightweight and unrestricted. Atomic swaps don’t demand expensive fees, and they aren’t vulnerable to theft. They also are resistant to regulatory pressure, and they rarely require KYC–although some DEXes aren’t taking chances. But despite these advantages, atomic swaps have yet to reach critical mass, both due to technical obstacles, and for practical reasons. Some Technical Issues In theory, atomic swaps should be less expensive than centralized exchanges, since there are no middlemen to take a cut. However, low fees are not actually guaranteed, as Beam (yes, that Beam) has noted. During an atomic swap, on-chain transaction fees still need to be paid, and these can be quite expensive. Off-chain swaps could solve this problem, but that requires solving other problems. On top of that, atomic swaps are not always fast. Sparkswap has argued that basic swaps are too slow for many trading situations: Bitcoin swaps can take more than an hour to finalize. This is a significant problem, Sparkswap says: crypto prices can fluctuate quickly, and this in turn can cause one side of the trade to back out, cancelling the transaction. Finally, compatibility is an issue. As Binance Academy explains, cryptocurrencies that are traded in an atomic swap must share a hashing algorithm, and they must be programmable. Although Komodo claims that it can swap 95% of coins, this is largely due to the prevalence of Ethereum’s ERC-20 standard, and some coins simply do not support atomic swaps. A Matter of Time? It could be that atomic swaps are making slow progress simply because they are a new technology. Although they were first proposed in 2013, the earliest swaps were manually organized on message boards. For instance, jl777 coordinated a Dogecoin to Litecoin swap on an NXT forum in 2014, preceding his own atomic exchange, InstantDEX, by about two years. Suffice to say, atomic swaps suffered from lack of visibility and accessibility for a long time. More significant swaps began to take place in 2017 when Charlie Lee participated in a Litecoin to Decred swap. In the same year, Komodo’s BarterDEX went live, and the Lightning Network began to popularize HLTC-based payment channels. Atomic swaps are now reasonably accessible thanks to an increasing number of automated services, but coordination between users is still an issue. If you want to perform a swap, you’ll still need to find a partner, and that’s not always possible. Additionally, atomic swap are just a side feature on some exchanges, such as Switcheo. As a result, they are not always highly visible. Which Atomic Swap Projects Are Moving Forward? There are a few projects that are trying to bring atomic swaps into the spotlight. This summer, Komodo launched AtomicDEX as a successor to BarterDEX, introducing a more streamlined interface and a new app for mobile devices. AtomicDEX also attempts to provide greater liquidity through integration with centralized exchanges, OTC trading desks, and other entities. Other services are confronting different issues. For example, Sparkswap is primarily trying to improve settlement speeds and interoperability. Meanwhile, Orion and WanChain are collaborating on atomic swap liquidity. Other services are focusing on specific coins: Switcheo is working with Ethereum and NEO, and Liquality is working with Bitcoin, Ethereum, and Dai. Many of these platforms have simple and appealing interfaces, and they couldn’t come at a better time. Ever since Shapeshift killed its anonymity features, there have been widespread calls for a simple, trustless, and anonymous coin-swapping service. If atomic swaps can overcome their challenges, they may eventually be able to fill the void that Shapeshift has left behind.   The post Can Atomic Swaps Reach Critical Mass? appeared first on Crypto Briefing.

With New Exchange Features, Wallets Aren’t Just for Storing Bitcoin Anymore

Bitcoin wallets play an essential role in facilitating every user’s interactions with the blockchain. They can connect to full nodes, store public and private keys, sign transactions and ultimately make it easy to store, send and receive bitcoin. In a nutshell, these software applications complete complex cryptographic functions under a friendly disguise: They offer an easy point-and-click (or touchscreen) experience that everybody who’s ever managed a credit card balance can understand. However, this functional simplicity is being challenged by a new trend that many wallet developers seem to be following: integrating exchange features to facilitate inter-currency trading and possibly increase liquidity.  There are three main categories of such additions: Wallets which allow users to buy bitcoin with their credit cards;Wallets which allow trades between BTC and altcoins;Wallets which allow the conversion of mainchain bitcoins and altcoins to Lightning Network satoshis (a third party-reliant precursor to atomic swaps). In order to better understand this functional trend, Bitcoin Magazine has contacted representatives from five popular BTC (and possibly multi-coin) wallets: Edge, Blockchain, BRD, Blue Wallet and Guarda. All of the respondents have received the same questions, and, fascinatingly, the exchange features have been implemented in different ways to serve varied purposes.  Edge Wallet and Third-Party Exchanges  In the quest to facilitate bitcoin trades, Edge wallet has chosen an interesting approach: Instead of building a centralized proprietary service or relying on a single third-party partner, the platform offers multiple options. Users’ transactions are assigned to the best available trade at the time on exchanges such as ShapeShift, Changelly, Wyre and Simplex. Furthermore, a direct link to Bitrefill is provided so users are able to buy various gift cards with bitcoin. “By integrating with third-party exchanges, users can acquire and trade cryptocurrency without the risk of leaving their funds with a third party. Users can also search for the best price across multiple exchange partners,“ said Edge CEO and co-founder Paul Puey. In a nutshell, Edge has added its exchange functions as a way of creating an “all-in-one” experience which suits newbies and minimizes risk through a selection of reputable services. If transferring funds to an exchange like Coinbase and withdrawing your fiat or bitcoin can take a long time (especially if the initial KYC verification process is involved), then dealing with Changelly or buying some BTC from Simplex is a lot faster and requires fewer signups. Puey highlighted Edge’s noncustodial nature as a competitive feature.  “The foundation of Edge and an advantage that sets us apart from other wallets is our key management,” he said. “Edge is a non-custodial wallet that allows users to control their own funds in a highly secured manner. Another advantage with Edge is that users now have a better way to transact without having to leave the wallet to access exchange functionalities.” The wallet seems to be increasingly popular thanks to these features, as the CEO pointed to a 100 percent growth in user base from one quarter to the next, even in the face of the 2018 bear market.  Blockchain Wallet, Swap and the Pit Blockchain is one of the oldest wallet solutions on the market, with a company history that began as early as 2011 and a long-standing reputation in the field of block explorers. Unlike Edge, it seeks to build an ecosystem of its own, with proprietary applications which are integrated in the main wallet. As a multi-cryptocurrency wallet, Blockchain has added Swap, a feature which allows users to trade between BTC, ETH, BCH and XLM, at prices close to the market valuation. According to Head of Strategy and General Manager Xen Baynham-Herd, “Swap allows users to exchange assets on-chain while maintaining complete control of their private keys.” As with Edge, users don’t have to leave the wallet’s interface when they want to trade between their cryptocurrencies, and the interface is simple enough to be accessible to newbies. According to Baynham-Herd, Swap “has been met with outstanding support from our users since we unveiled it last October.” Moreover, Blockchain has recently added the Pit — a more advanced exchange service which enables active trading between assets. Its interface resembles that of Coinbase Pro, as fiat options and more cryptocurrency pairs are included. Basically, it’s an attempt to extend the wallet’s usability while also providing extra features that bring liquidity. Instead of moving funds between exchanges and waiting for various verification processes, users can simply sign up for the extension service and perform the same actions.  The main issue with this approach is that the new exchange might not have enough liquidity to support large volumes — but if the service is good, then users will definitely create the financial prerequisites for intensive trading.  BRD Wallet and “Trade” BRD, formerly known as Breadwallet, is a popular and simple open-source wallet solution. Its GitHub commits date back to June 2015, and the contributions have consistently brought more features while maintaining the basic interface. In the words of Chief Strategy Officer Aaron Lasher, “BRD’s core competency is giving regular people the ability to safely store, send and receive cryptocurrency.” Correspondingly, trading your bitcoin for other assets can be made by simply tapping the “Trade” button on the bottom of the interface. After the process of selection is completed, a series of on-chain transactions will be made in order to deliver the expected cryptocurrency — which means that BRD is a mere facilitator, and not a custodian of the funds. According to the official website, “exchanging currencies may take up to 6 hours to complete.” Unlike with Edge, users don’t get to choose the third-party service that they will be using, as the process is simplified to include only the request. Lasher clarified that BRD collaborates with various partners to deliver the expected exchange service: “For those services, we use third-party integrations to broaden what our customers have access to.” Some of the most interesting things about BRD are those integrations which stem from regional partnerships and provide tailored services to users across the world. For instance, Canadians are able to buy bitcoin directly from the wallet interface thanks to a deal with Coinberry, while U.S. citizens who navigate the “Trade” button will automatically deal with Wyre. For European users, the service of choice is Coinify. In each instance, transactions are assigned by default to the relevant regional partner. BRD also allows users to buy bitcoin with their credit card or exchange their altcoins, and the order is followed by a series of email communications which present the delivery status (In times of greater network congestion, this might take longer). Once again, the provider chooses not to be a custodian by delegating responsibilities to other services. “Simplicity is necessary to appeal to non-techy users, security (which in our case, includes the fact that you alone have control of your money) is required for scale and reputation, and privacy (meaning that not only do you control your money, but that nobody else, including BRD, is able to look over your shoulder) is a cornerstone of civil society,” Lasher said. He noted that while some other exchanges have branched off into noncustodial wallet solutions, he suspects that they may not achieve much traction in the short term due to customer segmentation.  “If somebody is storing money with an exchange, it is highly likely that they are already willing to trade off some degree of privacy or control for the convenience of letting a third party deal with the security requirements,” he added. “Our customers, on the other hand, come to us will the full intention of mastering their coins, along with the incremental burden of keeping them safe.” Guarda and the Catch-All Approach Guarda is a relatively new bitcoin wallet solution which focuses on the same holistic approach to services, under a simple and straightforward interface. Of all the solutions presented in this article, Guarda supports the most cryptocurrencies and makes use of a more evident catch-all approach. When you decide to exchange your bitcoin, you basically get to choose between three of the most popular services (ShapeShift, Changelly and Changenow). Unlike other wallets which automatically assign the third-party exchange, with Guarda you get to choose according to your KYC preference (ShapeShift and Changelly have different requirements, for instance) and fees. “Exchange integration is an important step of building the ecosystem around the storage itself,” Guarda CMO Maria Carola explained. “For us, it is important to create one wallet that is enough to perform all the basic crypto management activities.” Interestingly, Guarda also enables support for the Ledger Nano S hardware wallet, which greatly improves security and control.  “We all want our funds to be safe and having a noncustodial wallet is one of the steps in this direction,” Carola added. “If you are into hardware wallets, you can also connect your Ledger Nano S device and manage the coins stored there in Guarda’s interface for overall convenience.” It’s also worth noting that the wallet is available on every platform and even has a browser extension — a feature which might be appealing to enthusiasts who want to use the functions on all devices. BlueWallet and the Marketplace In terms of freedom of choice, BlueWallet is easily the most generous of bitcoin wallets. Once you install the applications and deposit some BTC, you can choose from a great variety of services that allow you to spend or exchange your satoshis. Furthermore, BlueWallet happens to be the only Lightning-friendly and BTC-centric wallet we spoke with, offering a great advantage for Bitcoin enthusiasts. This approach also extends to the ability to connect to your own full node, thus removing trust in potentially malevolent third parties. From these perspectives, BlueWallet is in a league of its own and pleases a crowd which isn’t interested in trading altcoins but in maximizing the sovereignty of their BTC. Interestingly, the marketplace links to lots of online stores and services which provide a seamless conversion. You can basically imitate the function of a Lightning atomic swap with ZigZag, buy gift cards on Bitrefill, communicate via a borrowed number with Receive SMS and LN SMS, and even buy stickers from the Blockstream store or play video games on Satoshi’s Games. The only major feature missing in BlueWallet is one for purchasing BTC with your credit card. On the other hand, given the Bitcoin-only integrations and full node compatibility, it’s probably for the better. The project remains more cypherpunk and doesn’t have to deal with regulations that may force it to remove features. Depositing satoshis is a straightforward process and using them on either the main chain or Lightning is a great experience in itself. Product and UX representative Nuno Coelho told Bitcoin Magazine that BlueWallet’s main advantage is “the ability to verify and not trust, since BlueWallet allows you to run and plug in your own node. So you are not trusting third parties or centralized services; you are autonomous and sovereign on your own bitcoins.” Conclusion Though these wallets look similar and tend to have identical features, they have plenty of differences which make them more or less friendly with newbies or satisfactory for advanced users. In this regard, the table below lists the various qualities of each wallet presented in order to facilitate the process of making a choice. If you’d like to exchange your bitcoin for altcoins (or vice versa), then you should opt for Edge, Blockchain, BRD or Guarda. If you want to be in charge of the fees by choosing the service, then you will find Guarda most satisfactory (though Edge also operates with different services, but automatically picks the best rate). On the other hand, Blockchain seems to be the best at keeping it simple, since you don’t have to deal with any third parties and everything is integrated within the ecosystem. However, if you’re looking for a bitcoin-only wallet with Lightning support and the ability to perform swaps between the two payers, then BlueWallet will serve you best. For the sake of convenience, other criteria such as hardware wallet integration and the ability to buy bitcoin with your credit card have also been included in the chart below.  The post With New Exchange Features, Wallets Aren’t Just for Storing Bitcoin Anymore appeared first on Bitcoin Magazine.

Bitcoin SegWit transactions hit a new all-time high

Segregated Witness (SegWit) transactions are on the rise and recently hit a new all-time high. SegWit adoption on the rise SegWit is a solution to the Bitcoin scalability problem that was implemented via soft fork on Aug. 2017. It splits a transaction into two segments—appending signature, or “witness” data from the original transaction. By removing signature data, SegWit frees up 65 percent of the space in a given transaction, allowing more of them to fit in a block. This results in a significant drop in fees as more transactions could flow through the network. The integration of SegWit also permitted malleability in transactions allowing the implementation of functionality like the Lightning Network and atomic swaps operating as a smart contract layer upon the Bitcoin protocol. Now, SegWit transactions represent 50.5 percent of all the activity on the Bitcoin blockchain, according to TransactionFee.Info. This is a clear sign that its adoption continues to experience steady growth even though some of the most prominent companies in the space have failed to implement it. Source: Transactionfee.info Avoiding SegWit Before SegWit, the estimated fee paid for every transaction, depending on the confirmation speed, was around 147 to 230 satoshis per byte, equivalent to $3.11 to $4.87. At the present time, they only account for 44 to 87 satoshis per byte, which is between $0.82 and $1.6. Despite the major impact that its implementation has had on transaction fees, the world’s largest non-custodial wallet platform Blockchain.com has yet to integrate it. The firm is currently facing criticism for allegedly interrupting the adoption of Bitcoin because of its failure to implement SegWit and other Bitcoin scaling solutions. Back in 2017, Blockchain CEO Peter Smith stated that SegWit was ready to be adopted by his company, but, without explanations, has refused to do so. …before the hostile Core replies come: yes I support SW. Yes we are ready for it. And yes I've encouraged others:) — Peter Smith (@OneMorePeter) January 31, 2017 BitPay also put a hold on implementing SegWit, but it was until last month that it announced that its wallets would be allowed to use the protocol. In a blog post, BitPay revealed that it was thanks to a user on GitHub who reached out to them with a proposed change to the open-source Bitcoin client library, Bitcore. As the number of transactions using SegWit continue surging and more companies finally implement it on their platforms, Bitcoin becomes faster and cheaper to use. Based on the adoption rate that this technology has had and its impact on the Bitcoin blockchain, it seems like Bitcoin is getting closer to Satoshi Nakamoto’s idea of peer-to-peer electronic cash.

Tron [TRX] Up 5% Amid Rumours of Justin Sun Investing in Poloniex

Tron (TRX) has grown 5% in the last 24-hours following rumours of Tron CEO Justin Sun investing in Poloniex’s new digital firm.  Justin Sun May Invest in Poloniex On Friday, cryptocurrency exchange Poloniex announced in a blog post that it was spinning out of Circle and forming another company – Polo digital assets with new backers and a global focus. Among Poloniex developmental plans is focusing on global traders and spending $100M on expanding and developing the platform. Also, US customers will no longer be able to use Poloniex from the next month. According to rumours, one of the new backers of Poloniex is Justin Sun.
