​Longfellow-ZK is a Zero Knowledge circuit system developed by engineers at Google and specifically designed to create ad-hoc ZK circuits that can be executed at competitive speed both for presenting and verifying proofs. Here is our independent benchmark and the results are impressive.

This repository is a soft fork of Google’s Longfellow-ZK library, it is made in Europe and maintained by the Dyne.org foundation, based in Amsterdam to best serve the purposes of the EUDI ARF development.

Our effort is currently supported by the EU HORIZON grant nr.101132610 (PACESETTERS).
