The first native multi-chain system that supports EVM in the world. Making large scale blockchain applications possible

Project stage


Detailed description

PCHAIN is the first blockchain that supports Smart Data, based on which knowledge graph is formed and smart contract can be executed within a closed loop.

  • Every DApp has its own chain that makes it easy to browse and restore transactions
  • Supporting large-scale transactions
  • New consensus make computing parallelism
  • Supporting smart contract upgrade
  • High fault tolerance
  • Expansibility


Blockchain systems for smart contracts are faced with the following major problems at the same time:

  • There is a lack of a unified and effective Oracle. In the closed bitcoin ecosystem, all the data in the system is generated by the system, so there is no problem of the validity and authenticity of the data/knowledge itself. In a smart contract environment, however, there is a need to obtain the external system data/knowledge, and the validity and authenticity of external data/knowledge often becomes the bottleneck and obstacle of smart contracts.
  • Insufficient support for large scale transactions. Inevitably, single strand competition causes the waste of resources and browsing and restoring transactions are more complicated.
  • Increasing demand for cross-chain support. Handling the compatibility problems for smart contract data is far from easy.


The PCHAIN Network is a new infrastructure level public chain system with native support for  multi-chain  applications and EVM, providing an  open,  scalable  platform  for  third  party  developers in the industry and making it possible for large-scale enterprise applications based on smart contracts. The core technologies underlying the PCHAIN Network include:

  • The first native multi-chain architecture that supports EVM, with a consensus of POS based on multi-layer sharding mechanism that tremendously improves the performance of transactions.
  • A new Oracle mechanism based on the knowledge graph makes it easier to encapsulate smart contracts. The endogenous W3C compliant  smart  data of  the  PCHAIN  Network 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.
  • 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 smart contracts and other cross-chain requests on the PCHAIN Network. 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 question and answer, forecasting  markets,  the building of  distributed  knowledge  graph,  social  networks,  digital identities and others.
  • The trunked cross-chain solution makes the exchange of digital currency and digital assets more convenient. Various Tokens can be directly used to invoke smart contracts in the PCHAIN Network.


Native multi-chain 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.
