🔢 Technical Principles | Digital Signatures
· Definition: A signature is bound to the message it signs. If the content changes by even one byte, the original signature will no longer verify.
· Principle: The security of signatures relies on the discrete logarithm problem on elliptic curves: calculating a public key from a private key is fast, but deriving a private key from a public key is practically impossible.
· Note: Anyone asking you to provide your private key or recovery phrase to “verify a signature” is trying to scam you. A genuine signature never requires you to hand over your private key.
