Shiden Network 
Shiden is a smart contract platform for decentralized applications (dapps) on the Kusama network. Shiden is built to support “layer 2” solutions, which refers to secondary frameworks built on top of existing blockchains that improve upon a network’s scalability and transaction speeds. Shiden is intended to operate on Kusama as a parachain.
