**Abstract**

The presentation aims to describe:

* why proofs of valid ciphertext formation are necessary
* main issues when wrapping FHE algorithms into zkSNARKs
* tricks used to overcome those while building Greco
* benchmarks of Greco

**About the speaker**

Enrico is a researcher at PSE. His earliest contributions were in identity-related privacy-preserving applications such as [designated verifier proof](https://github.com/enricobottazzi/designated-verifier-proof) and [zk-sbt](https://github.com/enricobottazzi/ZK-SBT). He led the creation of [summa](https://github.com/summa-dev/summa-solvency), a production-ready proof of solvency solution for custodians. Lately, his research has focused on applications powered by Secure Multi-Party Computation. His first contribution to the space is Greco.
