Ring Signature
cryptography · privacy
A signature scheme that hides the true signer among a group, providing signer ambiguity.
Ring signatures let one member of a group produce a valid signature without revealing which member signed. Verifiers know the signer belongs to the ring, but the true signer is hidden among decoys.
Privacy depends on ring size, decoy selection, and how the scheme is combined with other tools. Ring signatures hide the signer, but they do not automatically hide amounts, recipients, timing patterns, or network metadata.
