ZK-Rollups is a layer 2 option that bundles together hundreds of transactions into one single transaction. This single transaction can then be deconstructed by smart contracts to verify each transaction individually. Using a "zero-knowledge proof" method for publicly recording transactions on the Ethereum blockchain, ZK-Rollups reduces the amount of storage and computational power required to validate blocks, as zero knowledge of the complete transaction data is required for a transaction to be verified. Moreover, ZK-Rollups allows for limitless scalability and instant transaction confirmations without compromising the security of assets.
