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.

Metronome is developing a cross-chain cryptocurrency with an emphasis on self-governance. Enable user to transfer value across decentralized platforms. The Metronome network is currently powered by the Ethereum-based MET token.

Kusama coin is the native coin of the Kusama blockchain, which is intended to serve as an unaudited and unrefined release of Polkadot. Kusama will serve as a trail version for Polkdadot, and will allow developers to build and deploy a parachain or try out Polkadot’s governance, staking, nomination and validation functionality in a real environment.
