Trinity is a new 2PC scheme, developed by Cursive. It combines ideas from a trio of cryptographic primitives: Garbled Circuits, KZG Witness Encryption, and PLONK.
This is a v0 version that has the first end-to-end implementation of the core scheme involving Garbled Circuits & KZG WE. PLONK will be added in a future version; it requires significant refactoring and isn't necessary to build initial applications.
The specific example used is a private hiring matcher. This is the same functionality that we previously built with Multi-Party FHE using phantom-zone, which you can find here.
This repo uses code from a number of different projects:
/circuits: Boolify to write a hiring 2PC circuit in Bristol format/jigg: JIGG for JavaScript native Garbled Circuit generation & evaluation/laconic: research-we-kzg, the original paper implementation of KZG Witness Encryption
