# Trusted Setup

The protocol also functions with zk-SNARK, which enables zero-knowledge proofs allowing users to demonstrate possession of information without needing to reveal it. The use of this technology is based **on open-source research made by Zcash team with the help of the Ethereum community**.&#x20;



The protocol currently uses Tornado.Cash[ Trusted Setup Community](https://tornado-cash.medium.com/tornado-cash-trusted-setup-ceremony-b846e1e00be1), which was launched in May 2020 & accounts [for 1114 contributions](https://tornado-cash.medium.com/the-biggest-trusted-setup-ceremony-in-the-world-3c6ab9c8fffa). This significant number of contributors makes it impossible to compromise the protocol by faking zero-knowledge proofs.
