### AI overview

The article distinguishes bridge k-of-n multisignatures from Byzantine fault-tolerant consensus. Multisignatures count approvals but do not detect compromised signers or recover from faulty leadership, while BFT protocols use multiple message rounds, leader changes, and fault tolerance. It discusses key management failures in Ronin and Wormhole and outlines automated key rotation, fault detection, and light-client or zero-knowledge verification as approaches to improve bridge security.

### Source excerpt

A bridge's k-of-n signature threshold isn't the same as Byzantine fault tolerance. Here's what each security model actually protects against.
