Validium Scaling

Mechanism

Validium scaling is a layer-2 solution designed to enhance blockchain throughput by executing transactions off-chain while maintaining data availability off-chain but verifying their integrity on-chain using zero-knowledge proofs. Unlike ZK-rollups, Validiums store transaction data off-chain, relying on a committee or a data availability committee to ensure the data remains accessible. This mechanism significantly boosts transaction capacity. It provides strong security guarantees for state transitions.
