Zcash founder Zooko Wilcox tweeted: “Two of the largest privacy services on top of Ethereum have been shut down: OFAC-sanctioned Tornado Cash and its creator Aztec’s Aztec Connect. Zcash can’t be shut down. I.e. won’t be shut down by ‘Electronic Token Company’ or anyone.”
EthHub co-founder sassal.eth refuted the above remarks, saying: “I really don’t want an industry leader like Zooko to say this kind of crap, and since he banned replying to this tweet, I have to correct this mistake here information.
Tornado Cash was never “closed”, it is still running today, and a majority of validators are still proposing blocks containing Tornado Cash transactions.
Aztec Connect was shut down because the Aztec team wanted to focus on their new product. They made it clear that it wasn’t shutting down due to regulatory pressure. Also, Zcash can be sanctioned in the same way that Tornado Cash is sanctioned (which of course doesn’t mean it will be “shut down”). “
