Securing a Cross-Chain Bridge
summary
Claims that trustless bridges are far more secure backed by concrete numbers: about $2B stolen so far, single key compromises costing over $1B, Ronin losing $650M, Nomad exploitable funds where white hats recover $32.6M. Describes tools and defenses: hub-and-spoke settlement on Ethereum to compartmentalize risk, a 24-hour challenge window for human response, audits and bug bounties, monitoring like a health checker and external watchers (Spreek). Hop’s design lets operators shut bonders and prevent multi-chain drains — used successfully to stop an attack.
