Blind Statechains
summary
Proposal for moving full UTXOs off-chain using a blind signing server that blindly signs transfer updates so ownership passes by handing over a transitory key rather than on-chain spending. Requires Schnorr/MuSig and adapter signatures to make L2 updates and atomic swaps work; federations (example: 8-of-12 threshold) hold the other co-signing key and publish blind-signature requests for fraud proofs. Built protocol sketches enable instant UTXO transfers, Lightning channel onboarding, and off-chain coin swaps; security depends on federation honesty and client-side unblinding/verification.
