The ‘Prefer to use txindex if available for GetTransaction’ Bitcoin Core PR Review Club meeting
includes eighth post in the series about preparing for taproot: multisignature nonces:
To validate a signature in Bitcoin, you fill out a publicly known equation with the signature, the message that was signed (e.g. a transaction), your public key, and a public nonce. It’s only possible for you to balance that equation if you know your private key and the private form of the nonce. Thus anyone seeing such a balanced equation considers the signature for that message and public key to be valid.
