Multisig

Multi-signature (multisig) refers to requiring multiple keys to authorize a transaction on a blockchain rather than a single signature from one key. It has a number of applications.

• Dividing up responsibility for possession of tokens among multiple people.
• Avoiding a single-point of failure, making it substantially more difficult for the wallet to be compromised.
• m-of-n backup where loss of a single seed doesn't lead to loss of the wallet.
