Multisig, short for "multisignature," is a security feature used in cryptocurrencies and digital transactions that requires multiple signatures to authorize a transaction. It involves the use of multiple private keys, typically held by different individuals or entities, to validate and execute a transaction. The specified number of signatures is predetermined, and all required signatories must provide their consent for the transaction to be approved and executed. Multisig adds an extra layer of security, as it mitigates the risk of a single point of failure or unauthorized access. It is commonly used for secure storage of funds, escrow services, and enhanced transaction security in blockchain-based systems.
