Halo

Halo is a cryptographic proving system designed to work with Zcash, removing the need for trusted setups and reducing the costs associated with ceremonies.

By eliminating reliance on trusted setups, Halo provides a more confident basis for Zcash and a faster, cheaper foundation for ongoing development and privacy-preserving applications.

Halo 2 builds on these advances, reinforcing its central role in zero-knowledge proofs and enabling scalable workflows across a range of use cases.
