NATIVE MULTICHAIN PLATFORM PCHAIN is the first native multichain system in the world that supports Ethereum Virtual Machine (EVM), which consists of one main chain and multiple derived chains. CONSENSUS WITH HIERARCHICAL SHARDING PIPELINE POS based multi layer sharding mechanism with a novel pipeline design that tremendously improves the performance of transactions. SMART CONTRACTS BASED ON SMART DATA A new Oracle mechanism based on the knowledge graph makes it easier to encapsulate smart contracts. W3C compliant smart data effectively adresses the issue of nonintelligence in smart contracts. CROSS CHAIN INVOCATION AND TRANSACTIONS The smart contracts of PCHAIN can be easily invoked with other nonnative Tokens (BCH, ERC20) by using the provided toolkit.
Launched on Dec 25, 2016, Obyte is a distributed ledger based on directed acyclic graph (DAG). Thanks to absence of blocks and miners, access to Obyte ledger is decentralized, disintermediated, free (as in freedom), equal, and open. Obyte is the first DAG based cryptocurrency platform to support dApps. Due to absence of miners and blocks, there is no risk of front-running and other miner manipulation, and dApps are safer and easier to develop than blockchain based dApps. DApps are developed in Oscript - a new language that avoids many unsafe programming patterns common in earlier dApp platforms. Thanks to its safety, Obyte is especially well suited for DeFi apps, some are already available on the platform, such as Discount Stablecoins (https://ostable.org), some are being developed. Other features include: self-sovereign identity, private untraceable currencies, sending crypto to email using textcoins, and extremely small-footprint libraries suitable for small IoT devices.
