The Celo Foundation announced the launch of Nightfall, an open-source, zero-knowledge privacy layer application built by EY and put into public domain, as a Layer 3 on the Celo network––marking the first payments-focused blockchain development of Nightfall. This integration enables private, enterprise-grade transactions, combining confidentiality with the benefits of public blockchain infrastructure, and positions Celo at the forefront of enterprise B2B payments, a sector expected to exceed $180T in cross-border flows. “Deploying Nightfall on Celo brings enterprise-grade privacy to the same mobile-first infrastructure that already supports millions of users globally,” said Rene Reinsberg, Celo Co-Founder and Celo Foundation President. “With this Layer 3, Celo now offers a comprehensive solution for both individual and institutional payment needs in markets underserved by traditional financial infrastructure.” Nightfall has been in development in the public domain since 2017. The latest iteration, Nightfall_4 (NF_4), leverages Zero-Knowledge Proof (ZKP) technology to enable the private transfer of multiple token standards, including ERC-20, ERC-721, ERC-1155, and ERC-3525.
