Announced Tuesday, EY’s protocol, internally code-named Nightfall, has been developed over the last year by the consulting firm’s team of over 200 blockchain developers and will be published
in May. The protocol was created for such use cases as supply chains, food tracing, transactions between branches of a company and public finance.
Like other enterprise blockchain platforms, Nightfall takes advantage of a technology called
zero-knowledge proofs to allow private transactions on a shared ledger. But unlike most such endeavors,
EY’s software is intended to run on top of the public ethereum network, not a private variant.
