Definition ∞ Zero-knowledge rollups are a type of layer-two scaling solution for blockchains that bundle numerous transactions off-chain and then submit a compressed summary along with a cryptographic proof to the main chain. This proof, generated using zero-knowledge technology, verifies the validity of all bundled transactions without revealing their underlying data. They significantly enhance transaction throughput and reduce fees.
Context ∞ Zero-knowledge rollups represent a pivotal advancement in blockchain scalability, attracting substantial attention from developers and users seeking to overcome network limitations. Discussions frequently address the technical complexities of implementing ZK proofs, the security assurances they provide, and their potential to facilitate broader adoption of decentralized applications. Future developments will likely concentrate on optimizing proof generation efficiency and broadening the range of applications compatible with ZK rollup technology.
