What Is a ‘Multi-Signature’ (Multisig) Address?
A multi-signature (multisig) address is a type of Bitcoin address that requires more than one private key to authorize a transaction. For example, a 2-of-3 multisig requires any two of the three designated private keys to sign a transaction.
This enhances security by eliminating a single point of failure and is commonly used for joint accounts, escrow services, and cold storage to distribute control.
