Statechains provide a unique Layer 2 approach to scaling Bitcoin ($BTC) transactions, according to Ruben Somsen. As part of a multi-sig transaction, a statechain governor signs off on transactions in coordination with the holder of the real private key, not dissimilar to Blockstream's Liquid federated sidechains. The statechain governor's nature decreases fault risk while allowing off-chain transactions. Statechains are also highly agreeable with Lighting, permitting users to interact with channels in a more dynamic fashion than ever before.
