AION calls itself a 3rd generation blockchain network, and is primarily focused on connecting blockchain networks. AOIN aims to solve the interoperability issues facing the various blockchains, and be the connecting bridge between them. AION's cross-chain platform has different consensus mechanisms for interchain and on-chain transactions. The on-chain consensus mechanism combines BFT (Byzantine Fault Tolerance), dPoS (Delegated Proof-of-Stake) and a new neural network inspired verification algorithm known as Proof-of-Intelligence.
Interchain transactions are managed by bridges. The bridges has a consensus mechanism that is different from the main AION chain, and each bridge is secured by an individual consensus. The bridge validators will be rewarded by interchain transaction fees.

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.
