ZKsync Validium

Definition ∞ ZKsync Validium is a specific type of zero-knowledge rollup solution designed to scale Ethereum by processing transactions off-chain while maintaining a high degree of security. Unlike ZK-rollups, Validiums store transaction data off-chain but use zero-knowledge proofs to verify the integrity of these off-chain computations. This approach offers extremely high transaction throughput and significantly reduced fees. It provides strong data availability guarantees through external committees.
Context ∞ ZKsync Validium is a prominent solution in discussions about Ethereum scalability and layer-2 technologies. Debates often focus on the trade-offs between data availability models, security assumptions, and transaction costs compared to other scaling solutions. Future developments will likely see Validiums playing a significant role in supporting high-volume decentralized applications and enterprise blockchain solutions.
