multisig wallet

A cryptocurrency wallet that requires signatures from multiple private keys to authorize a transaction. Instead of one person holding one key, you distribute signing authority across 2, 3, 5, or more parties. Common setup: 2-of-3 (any two of three keyholders can sign) or 3-of-5 (any three of five). Why it matters: multisig reduces single points of failure. One key gets compromised? Doesn't matter—attacker still can't move funds alone. Useful for teams managing shared treasury, exchanges holding customer funds, or paranoid individuals splitting control between hardware wallets, cold storage, and a trusted third party. Trade-off: slower transactions, more complexity, easier to accidentally lock yourself out forever if you lose keys. Related to on-chain security rather than domain registration, but many bulletproof hosting and crypto business operators use multisig for operational wallets—which is why you see it mentioned in offshore crypto infrastructure circles.
