Seele is developing a blockchain ecosystem that will consist of subnets optimized for different use cases. Seele's Forest Network will have subnets that will operate independently and can interact with each other through cross-chain and cross-domain protocols. Seele has a neural consensus algorithm that was inspired by the inner workings of the human brain. It asynchronously processes and sorts data in a large-scale decentralized environment, using ε-differential agreements to allow all nodes within a network to reach consensus. Compared to existing consensus algorithms, it ensures greater fault-tolerance and is significantly more efficient. Its performance also scales linearly as network size increases, allowing it to be widely adaptable to many different use cases.

Mercury Token is a Waves-based token that was created to facilitate cross-chain communication, and timestamping, between the Waves blockchain and the Jupiter blockchain.

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.
