Multi-Signature (Multi-Sig)

Category: legal

A cryptographic script configuration requiring multiple private keys to authorize a single Bitcoin transaction.

Multi-sig scripts act as a security vault (e.g., a "2-of-3" configuration). To spend the locked UTXOs, at least two separate keys must sign the transaction data. This is an essential architectural standard for institutional custody, protecting local sovereign reserves from single-point-of-failure hacks or physical key loss.

Common Examples

• We locked our company’s long-term reserves inside a 3-of-5 multi-sig script distributed across geographically isolated hardware nodes.
• The automated escrow system relies on a native multi-sig script to release funds only when both the buyer and the platform oracle sign off.
