Double-Signing Detection
Double-signing detection is a security mechanism that identifies when a validator signs two different blocks at the same height. This is a critical violation of consensus rules, as it can lead to chain forks and undermine the integrity of the ledger.
Detection systems are integrated into the consensus layer to monitor block headers and identify conflicting signatures. Once detected, the protocol automatically triggers a slashing event to penalize the malicious validator.
This process is designed to be trustless and automated, ensuring that no human intervention is required to maintain the network's state. It serves as a fundamental protection against attempts to rewrite history or double-spend assets.
Effective detection is a prerequisite for any robust proof of stake system.
