PCHAIN is developing a multichain ecosystem that will support the Ethereum Virtual Machine (EVM).PCHAIN's architecture will consist of one main chain and multiple child chains. They hope to improve transaction times with a Proof-of_Stake consensus mechanism that will be combined with sharding.. The PCHAIN network is currently powered by the Ethereum-based PAI token.

Wanchain is a cross-chain protocol for inter-chain transactions. It was originally a fork of Ethereum, but is now a completely separate blockchain called the WAN chain, that also has a Proof-of-Stake (PoS) consensus mechanism. Wanchain is designed to be a decentralized and interconnected platform to exchange digital assets across separate blockchains. It is meant to connect the growing number of blockchain projects and make them inter-operable.
