EY Upgrades Nightfall With Zero-Knowledge Tech for Private Ethereum Transactions

EY has rebuilt its enterprise-focused Ethereum layer-2 blockchain Dusk as a zero-knowledge rollup, eliminating ready durations for transaction finality and simplifying the platform’s structure.

The replace, launched Wednesday, replaces Dusk’s earlier optimistic rollup design with a cryptographic method that verifies transactions earlier than submission to Ethereum. This removes the necessity for problem durations that might delay finality for days.

Now dubbed Nightfall_4, EY’s technical transition affords a number of benefits past pace. 

Changing a “cryptoeconomic method with a cryptographic method” simplifies Dusk’s structure as a result of, consequently, there can be “no must accommodate difficult incorrect blocks,” EY mentioned in a statement.

The transfer gives “the identical privateness and scaling that model 3 enabled, however now with near-instant finality and a simplified structure,” Paul Brody, international blockchain lead at EY, mentioned in an announcement.

Although EY mentioned Nightfall_4 and supporting instruments are publicly obtainable, their GitHub repository doesn’t replicate the change and opens a 404 error, which implies it hasn’t been up to date.

EY didn’t instantly reply to Decrypt’s request for touch upon that entrance.

From optimistic rollups to zero-knowledge

Whereas optimistic rollups require game-theoretic safety assumptions and financial incentives to catch fraud, zero-knowledge implementations present stronger cryptographic ensures.

The brand new design additionally enhances privateness by zero-knowledge proofs that enable transaction validation with out revealing underlying information.

Dusk stays permissioned for EY’s company shoppers regardless of its open-source code base. The platform allows personal transactions on Ethereum whereas sustaining the principle community’s safety advantages and lowering prices.

Enterprise customers, in the meantime, would nonetheless profit from Dusk’s integration of industry-standard id certificates, which stop nameless utilization whereas preserving transaction privateness.

EY began growth of Dusk in 2019. In a 2022 interview with Decrypt, EY blockchain lead said the agency needs “to be one of the best on earth at Ethereum.”

The timing coincides with improved regulatory circumstances for privateness applied sciences, following the U.S. Treasury’s resolution to lift sanctions on Twister Money, a beforehand blacklisted crypto mixer.
