Working with Hashi

Hashi is an EVM Hash Oracle Aggregator, designed to facilitate a principled approach to cross-chain bridge security. Hashi is developed and maintained further by the Cross-chain Alliance team.

The primary insight being that the vast majority of bridge-related security incidents could have had minimal impact if the systems relying on them had built in some redundancy. In other words, it's much more secure to require messages be validated by multiple independent mechanisms, rather than by just one. We call this setup a RAIHO (Redundant Array of Independent Hash Oracles).
