Private Public key cryptography.
I barely understand it.

“In short, the unique s value provides a pathway for getting to the randomly-generated point r.
You can give these two pieces of information to someone else, and starting from the public key point Q they can use the s value to help them get to the random point r. The trick here is that only the person with the corresponding private key d could create a valid pathway to this random point provided by s.
This pathway also has the message hash z encoded in to it, which is what effectively allows us to create signatures for messages; nobody can create the pathways from the public key to a random point on the curve via the message hash without knowing the private key it was created from.” nostr.fmt.wiz.biz
They could have said that they were gonna hike The interest rates and Bitcoin still sometime in October Is gonna melt faces Because of this little thing baked into the protocol called the halving nostr.fmt.wiz.biz
