making it possible for large-scale enterprise applications based on smart con-
tracts. The core technologies underlying PCHAIN include:
1) The first native multi-chain architecture that supports EVM, with a con-
sensus of POS based on multi-layer sharding mechanism that tremendously
improves the performance of transactions.
2) A new Oracle mechanism based on the knowledge graph makes it easier to
encapsulate smart contracts. PCHAIN's endogenous W3C-compliant smart
data effectively addresses the issue of non-intelligence in smart contracts and
can become a fundamental element of smart contracts, just like the market
exchange rate data from the external.
3) The goal of PCHAIN Smart Data is to generate valuable data that filters
out noise and make it an integral part of Oracle. These smart data can be
used in various PCHAIN's smart contracts and other cross-chain requests.
Smart data, on the one hand, can serve as an intermediary between blockchain
and artificial intelligence, and on the other hand, facilitates the integration
of blockchain with big data.
Therefore, it has a vast application prospects, including decentralized ques-
tion and answer, forecasting markets, the construction of distributed knowl-
edge graph, social networks, digital identities and others.
4) The trunked cross-chain solution makes the exchange of digital currency and
digital assets more convenient. Various Token (e.g. BCH, ERC20) can be
directly used to invoke smart contracts in PCHAIN.
