Definition ∞ A zero knowledge layer refers to a blockchain or protocol built upon or integrated with zero-knowledge cryptography to enhance privacy and scalability. This layer processes transactions or computations off-chain, generating cryptographic proofs that confirm their validity without revealing sensitive underlying data. It then submits these concise proofs to a main chain for verification.
Context ∞ Zero knowledge layers, such as ZK-rollups, are at the forefront of efforts to scale blockchain networks and improve transactional privacy. They address the limitations of main chains by enabling a higher throughput of transactions while maintaining the security guarantees of the underlying network. News often reports on the development and deployment of various zero knowledge layer solutions, highlighting their potential to transform the architecture and capabilities of decentralized finance and web3 applications.
