  • Developers can use Nightfall source code to create privacy-aware transactions on the public Ethereum block chain

LONDON, January 18, 2023 /PRNewswire/ — Organizations EY and Polygon have updated the public domain source code for Nightfall to enable the development of privacy-focused enterprise blockchain solutions. Nightfall is an Optimistic Zero-Knowledge (ZK) roll-up that helps enable private transactions on the public Ethereum blockchain. With Nightfall, companies can efficiently orchestrate private transactions on the Ethereum backbone without compromising the transparency, data immutability, and security that Ethereum provides.

Paul BrodyEY Global Blockchain Leader, says:

“This update marks the preparation of Nightfall to enable the development of enterprise solutions. With over six months of testnet operations, we consider it to be a ‘production beta’, ready for enable customers’ supply chain and business operations.”

EY brought Nightfall into the public domain for the first time in 2019 as a set of protocols enabling private transactions on the Ethereum blockchain. In September 2021EY has partnered with Polygon to create a beta version of Nightfall that can alleviate network congestion and high transaction prices resulting from increased usage and wider adoption of Ethereum. EY’s core software and service offerings in the global blockchain market – EY OpsChain and EY Blockchain Analyzer – use Nightfall, and both are delivered via EY Blockchain’s SaaS platform, Blockchain.ey.com.

This version of Nightfall introduces two significant changes over previous versions: first, to prevent control by one organization or group, the code can be deployed in a fully decentralized manner. Second, to prevent anonymous use while maintaining an open, permissionless network model, users must have an enterprise-class X.509 credential certificate to deposit or withdraw. X.509 certificates are a widely adopted open standard for identification used on the Internet and are available from many different certificate authorities.

Nightfall will remain in the public domain to facilitate adoption of privacy-focused enterprise solutions among companies seeking entry. Ethereum and conduct meaningful business on the network.

Antoni MartinPolygon Co-founder responsible for Nightfall says:

“The decision to update Nightfall into the public domain is a major step in scaling the Ethereum ecosystem and will open up new use cases for businesses in Web3.”

Nightfall (renamed Nightfall D3) source code and supporting tools are in the public domain and are available on Github at https://github.com/EYBlockchain/nightfall_3.
