Zero-knowledge rollups
Zero-Knowledge Rollups are a scalability solution for blockchain networks within the Web3 ecosystem. They enable more efficient and cost-effective processing of transactions and smart contracts. Zero-Knowledge Rollups work by aggregating multiple transactions off-chain, creating a 'rollup' or summary of these transactions. This rollup is then submitted to the blockchain, significantly reducing the computational and storage burden on the main chain. What sets Zero-Knowledge Rollups apart is their use of cryptographic techniques to prove the validity of these off-chain transactions without revealing their details, ensuring security and privacy while enhancing blockchain scalability.
