In Rust, We Trust: The Mighty Schnorr Signature
"I have been learning Rust, and it is rock solid when it comes to producing cryptography-related code. So, let’s cut our teeth on the mighty Schnorr signature. This method has the great advantage that we can have multiple signers to a message or a transaction, and end up with a single signature for all the signers. It is now being used in Bitcoin transactions so that we have an efficient signature for a transaction that involves multiple entities.
"The patent
"In Feb 1989, Claus Schnorr submitted a patent which was assigned to no one. It has 11 claims, and allowed digital signatures to be merged for multiple signers [here]:
