Tornado Cash, an Ethereum-based mixer that uses zero-knowledge evidence, completed his trust installation ceremony, taking a key step towards becoming “totally trustless”.

The non-custodial service uses zk-SNARK technology and third-party relays to mask the association between a sender address and a recipient address, allowing users to withdraw funds anonymously.

Systems that use zk-SNARKs require trust setup, an elaborate process that relies on multi-party computation to generate a critical pair of cryptographic keys. Trusted configurations are vulnerable to manipulation, but an attacker would have to compromise every participant in order to undermine the system’s confidentiality guarantees. So in theory, the larger the number of participants, the more secure the process.

The most famous trust setup ceremonies in the crypto space so far have been Zcash. In October 2016, Zcash generated its very first set of “public parameters” via a ceremony attended by six participants. Then, in 2018, he hosted another ceremony as part of his Sapling upgrade. This involved 87 participants. The Tornado Cash team said its configuration had a total of 1,114 “contributions”, making it “by far the largest” to date.

Tornado Cash has been operational since August of last year. In previous versions, the participants in the trusted configuration were only the members of the project.

In March, The Block Research reported that it had already seen $ 4.4 million in deposits.

Now that the trust setup is complete, the developer team plans to “make sure everything is working as expected” before adding some final touches to the system “so that no one can ever change it,” according to an article by blog.
