What is the Definition of ZK Rollups?

ZK Rollups are a type of Layer 2 scaling solution for blockchains that utilize zero-knowledge proofs to bundle numerous transactions off-chain into a single batch. This batch is then submitted to the main blockchain with a cryptographic proof confirming the validity of all included transactions. This method significantly reduces transaction fees and increases throughput by processing data off the main chain while inheriting its security guarantees. They represent a key technology for enhancing blockchain scalability and efficiency.

What is the Context of ZK Rollups?

The current discourse surrounding ZK Rollups focuses on their rapid development, increasing adoption by various blockchain protocols, and their potential to revolutionize transaction processing. Competition among different ZK Rollup implementations is driving innovation in proof generation and data availability techniques. Future developments are expected to address challenges related to prover decentralization and the complexity of smart contract support. The widespread deployment of ZK Rollups is seen as a critical step towards achieving mass adoption of blockchain technology.
