Cryptographic Authority
Multi-Signature Wallet
A wallet requiring multiple private keys (M-of-N) to authorise transactions — an approach CLAVI transcends with threshold signing for greater privacy.
Definition
A cryptocurrency wallet that requires multiple private keys to authorise a transaction, typically expressed as M-of-N (e.g., 2-of-3). Unlike single-key wallets where one compromised key means total loss, multi-sig distributes authority. However, multi-sig has protocol-level limitations: it is chain-specific, reveals the signing structure on-chain, and requires all participants to use the same protocol. Threshold signing — as implemented in CLAVI — achieves similar security goals with greater privacy and cross-chain flexibility.
