Multisig protection, short for multi-signature protection, is a security feature for digital asset wallets or smart contracts that requires multiple private keys to authorize a transaction. Instead of a single key, a predefined number of approvals from a group of keys is necessary to move funds or execute an action. This significantly enhances security by distributing control and mitigating the risk of a single point of failure.
Context
In crypto news, multisig protection is frequently highlighted as a superior security practice for securing large digital asset holdings, particularly for institutions, exchanges, and decentralized autonomous organizations (DAOs). Reports often cover its implementation in treasury management or as a safeguard against hacks and internal collusion. Adopting multisig protection is a key step towards improving the overall security posture of the digital asset ecosystem.
