It also helps to decentralize power, as no single person can approve a transaction on their own.
In a multisig setup, there are typically two types of parties: signers and cosigners. A signer is somebody who initiates a transaction, while a cosigner is somebody who needs to approve the transaction before it can go through.
In order for a transaction to be authorized, a certain number of signatures (m) out of the total number of signers and cosigners (n) is required. This number is typically set by the wallet provider. For example, a 2-of-3 multisig wallet would require two signatures out of three possible signers in order to authorize a transaction.

This is possible because the terms of the contract are encoded into the blockchainWhat Is The Blockchain? The blockchain is the public record of bitcoin transactions, which are organized into blocks that are all chronologically linked to one another. Because every block is.... This means that once the conditions of the contract are met, the transaction will be automatically executed.
