Definition ∞ Zkrollup technology is a layer-2 scaling solution for blockchains that bundles numerous off-chain transactions into a single batch and generates a cryptographic proof of their validity. This proof, known as a zero-knowledge proof, is then submitted to the main blockchain, significantly reducing the data stored on the mainnet. It enables high transaction throughput while inheriting the security guarantees of the underlying layer-1 chain. This method enhances scalability and efficiency.
Context ∞ Zkrollup technology is a prominent topic in discussions about blockchain scalability, particularly for Ethereum, as it offers a robust solution for increasing transaction capacity and reducing fees. News often covers the development and deployment of various zkrollup implementations, their specific trade-offs, and their potential to onboard a wider user base to decentralized applications. Observing the progress of zkrollups provides insight into the future direction of blockchain infrastructure and its capacity for mainstream adoption.
