Recent MPC research from Cursive and PSE enables a new concept called "digital pheromones": the ability to produce lightweight, privacy-preserving signals that people can use to coordinate safely and efficiently. The primary result we will cover is Trinity, a new 2PC scheme with nearly ideal UX/DevX, built on the trio of PLONK, Garbled Circuits, and KZG Witness Encryption. We will do a live demo with attendees and explore what a future filled with digital pheromones will enable!
