The EY and Polygon organizations update source code for blockchain privacy-based protocol Nightfall

Developers can use the Nightfall source code to create privacy-enabled transactions on the public Ethereum blockchainand EY Blockchain Analyzer – use Nightfall, and both are delivered through EY Blockchain's SaaS platform,

This version of Nightfall introduces two important changes over prior versions: First, to prevent control by an organization or group, the code can be deployed on a fully decentralized basis. Second, to prevent anonymous usage while retaining an open and permissionless network model, users are required to have an enterprise-class X.509 identification certificate to deposit or withdraw. X.509 certificates are a widely adopted open standard for identification used on the internet and are available through many different certificate authorities.

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

Antoni Martin, Polygon Co-founder responsible for Nightfall says:

"The move to update Nightfall in the public domain is a major milestone in scaling the Ethereum ecosystem and will open up new use cases for enterprises in Web3."

The source code for Nightfall (renamed Nightfall D3) and supporting tools are in the public domain and are available on Github at
