🗒️ Conversation Summary: Developers Lloyd Fournier and AdamISZ discuss the security of using signature adaptors for multiparty swaps in Bitcoin transactions. While single signer adaptors can reveal a secret when a signature on a pre-defined message is published, there is confusion about their usefulness in a Bitcoin context. Multisig is necessary, but not necessarily key aggregated. A new analysis on the security of using signature adaptors for multiparty swaps has been posted on GitHub.
