A Schnorr signature is a sort of digital signature used to confirm and authorise transactions on the Bitcoin blockchain. Think of a digital signature as an digital model of a bodily signature that is nearly inconceivable to pretend. It was invented by Claus-Peter Schnorr, a German mathematician and cryptographer.
Each holder of a Bitcoin pockets owns a public key and personal key. To obtain Bitcoin, you share your public key with a sender. Your personal key, then again, lets you ship and transact with Bitcoin in your pockets. You wouldn’t wish to share your personal key with the community each time you transact as it will give folks entry to your pockets, which is why the 2 keys are utterly completely different.
A Schnorr signature ensures that the personal and public keys are from the identical pockets.
