Verifiable Secret Sharing

Definition ∞ Verifiable secret sharing is a cryptographic protocol that partitions a secret into several distinct components, or shares, allocated among multiple participants. The secret can only be reconstructed when a sufficient quantity of these shares are assembled. A key aspect is that participants can authenticate the correctness of their shares without disclosing the secret itself, protecting against deceptive share dissemination.
Context ∞ This protocol is essential for building secure multiparty computation frameworks and threshold cryptography within decentralized systems. It considerably strengthens security for digital asset administration, such as multisignature wallets or decentralized autonomous organization governance, by removing individual points of compromise. The ability to verify shares provides resilience against untrustworthy participants, an essential element for confidence in blockchain applications.
