Accounting services firm Ernst & Young (EY) released a set of tools called Nightfall 3 on Thursday in an attempt to reduce the fees on the Ethereum blockchain lower without sacrificing privacy.
The Nightfall 3 protocol—like its 2019 predecessor ‘Nightfall’—is for privately managing transactions on Ethereum. EY’s latest incarnation is a ‘ZK-Optimistic Rollup’ protocol since it combines zero-knowledge proofs with a transaction verification mechanism known as an Optimistic Rollup.
Zero-knowledge proofs use cryptographic algorithms to verify that a piece of information sent across the blockchain contains the right kind of information without revealing it. Nightfall 3 aggregates ZKP transactions into groups called ‘rollups’, which are ‘optimistic’ because they are all assumed to be true unless proven otherwise. This means that validators no longer have to verify the transactions, lowering costs.
