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.
