Multi-sig
System requiring multiple signatures to approve a transaction.
Beginner-friendly explanation
Multi-sig is a method to secure a crypto wallet by requiring multiple people (or devices) to approve a transfer. Like a safe that needs multiple keys. Example: To send funds from a multi-sig wallet, two out of three signatures are required.
Intermediate-level insight
A multi-sig wallet uses a smart contract or a native structure (e.g., Bitcoin, Ethereum) to require a minimum number of signatures (e.g., 2/3 or 3/5). It’s often used for team treasuries or institutional vaults. Example: A company sets up a 3/5 wallet so three executives must jointly approve fund movements.
Advanced perspective
Complex multi-sigs can be combined with governance mechanisms (DAOs) and dynamic rules (timelocks, revocations). They reduce internal fraud risk and strengthen resilience against physical or social attacks. Example: A DeFi protocol requires 5/9 multi-sig approval before any smart contract upgrade.
