PChain (PAI) is an ERC-20 compliant non-refundable functional utility token developed on Ethereum blockchain. PChain solves three major problems with the present blockchain systems i.e. unable to handle large-scale transactions, lack of unified Oracle and cross-platform/Cross-chain smart contract functionality. PChain solves these problems by introducing a new infrastructure level public chain system which supports Ethereum Virtual Machine and multi-chain applications. PChain uses Proof ofShow more [+] Stake consensus protocol based on multi-layer sharding mechanism which highly improves the transaction speed. PChain introduces a new Oracle mechanism based on the knowledge graph which makes it easier to adopt the smart contracts. The integral part of the Oracle is to filter out the unnecessary data from valuable data (smart data). This smart data can be used on cross-chain requests and various smart contracts. Other features of PChain includes high fault tolerance, supporting smart contract upgrade and expansibility. PChain supports BCH and all ERC-20 complaint tokens to invoke the smart contracts.
PChain is initially launched as an ERC-20 token on Ethereum, however, the development of their mainnet is also in progress. Once the mainnet launches, the PAI token will be shifted to the PChain blockchain. The PChain relies on masternodes for the consensus. The masternodes are selected randomly by selecting a node from the clients expressing the need for building consensus for a certain chain. The nodes are incentivized using PChain (PAI) tokens for the blocks generated.
PChain is managed and governed by PChain Foundation, a non-profit organization. The board of directors is the ultimate decision-making body in the PChain foundation related to feature improvements, upgrades, and development of opensource network community. PChain was the vision of Dr. Feng (Jeff) Cao, the inventor of the first blockchain patent from China. There are 16 other members in the team.
