Multiple signature, often referred to as multisig, is a security feature used to require more than one signature to authorize a transaction. Instead of a single private key proving ownership, multiple keys from different parties must be used to sign off on a transaction. This setup enhances security, as it reduces the risk of theft or unauthorized access. For example, a wallet can be configured so that at least three out of five designated keys are needed to complete a transaction. If one key is compromised, the funds remain safe until the additional signatures are provided. Multisig is especially useful for organizations, where a group of individuals collectively manages funds. It allows for shared control and responsibility, making financial decisions more democratic and transparent. Different configurations can be established, depending on the level of security desired, with options like 2-of-3 or 3-of-5 signing requirements. This flexibility makes multisig a popular choice for those looking to enhance the security of their assets and transactions.
