The protocol addresses the 'aggregation wall' problem where quantum computers could forge BLS signature aggregates by eliminating aggregation altogether - validators count each other's votes directly instead. Monad blockchain is building quantum-safe consensus as part of its post-quantum roadmap, with this being the first of a three-part series explaining consensus concepts.
