📝 Summary: The blinded statechain protocol has been updated to mitigate the Wagner attack by verifying previous computed values. Coins now require verification of previous signatures and backup transactions. Transfer data is encrypted with the new owner’s public key, and blind signatures are used to ensure security. Progress has been made on the development of the blinded two-party Schnorr scheme for statechains.

✉️ Message by Tom Trevethan on 07/08/2023: The blinded statechain protocol has been updated to include mitigation against the Wagner attack by requiring verification of previous computed values by new statecoin owners.
✉️ Message by moonsettler on 08/08/2023: The author discusses an update to the blinded statechain protocol to mitigate the Wagner attack and ensure the honesty of computed values.
✉️ Message by Tom Trevethan on 09/08/2023: Coins in the statechain protocol require verification of previous signatures and backup transactions. Transfer data is encrypted with the new owner’s public key, and a non-identifying key can be used for authentication with the server.
✉️ Message by Lloyd Fournier on 10/08/2023: The sender is questioning the use of schnorr blind signatures in the statechain protocol and the potential for malicious signatures. They also suggest enforcing sequential blind signing to prevent attacks.
✉️ Message by Tom Trevethan on 10/08/2023: Blind signatures are used in the statechain protocol for bitcoin transactions to ensure security and prevent malicious signatures. The server generates partial signatures, but does not have access to the full key, message, or final signature. The receiver must verify all previous backup transactions and the total number of signatures before accepting the coin.
✉️ Message by Lloyd Fournier on 14/08/2023: Lloyd asks Tom if parallel signing requests are required in the statechain protocol and questions the use of Schnorr blind signatures.
✉️ Message by Tom Trevethan on 30/08/2023: Progress has been made on the development of the blinded two-party Schnorr scheme for statechains. Mitigations for attacks have been implemented, and the scheme has been implemented in a blind server and client.
