A former Twister Money developer claims to be constructing a brand new crypto mixing service that goals to unravel a “important flaw” of the sanctioned crypto mixer — which he hopes will persuade U.S. regulators to rethink its place on privateness mixers.
The code of a brand new Ethereum-based mixer, “Privateness Swimming pools,” was launched on GitHub on Mar. 5 by its creator, Ameen Soleimani.
In a 22-part Twitter thread, Soleimani defined that the “important flaw” with Tornado Cash is that customers can not show that they’re not related to North Korea’s Lazarus Group or any felony enterprise for that matter.
1/ We fastened @tornadocash
v0 of https://t.co/Nt4b2Tgx1D is stay on @optimismFND
take a look at out the demo, however please notice:
– that is experimental code
– it has not been audited
– the trusted setup is untrusted

With Privateness Swimming pools, nonetheless, Soleimani explained that depositors and withdrawers may choose out of an anonymity set that accommodates an deal with related to stolen or laundered funds.
This function of Privateness Swimming pools is executed with zero-knowledge (ZK) proofs, which means that the privacy of the user is preserved:
“Now, customers have the choice to assist regulators isolate illicit funds, with out revealing their total transaction historical past […] With privateness swimming pools, simply because somebody deposits into the identical good contract as you, it doesn’t suggest they’ll additionally power you into sharing an anonymity set with them. It is your alternative.”
Soleimani supplied an indication of how Privateness Swimming pools is used:

The developer hopes the answer will empower “the neighborhood to defend in opposition to hackers abusing the anonymity units of trustworthy customers with out requiring blanket regulation or sacrificing on crypto beliefs.”
Whereas Privateness Swimming pools is already stay on Optimism, Soleimani famous that the primary model of the privateness protocol remains to be in its “experimental” stage as a result of the code isn’t full and has not been audited, however he’s “fairly near having this prepared.”
To see the protocol progress additional, Soleimani needs on-chain forensics platforms like Chainlaysis and TRM Labs to conduct tracebacks on deposits in order that customers of the privateness software don’t need to manually create their very own subset exclusion lists.
In making the case for on-chain privateness protocols, Soleimani cited what he described as an “wonderful” report by the Federal Reserve Financial institution of St. Louis in Missouri which examined the trade-offs between on-chain privateness and regulation:
“Their report proposes to realize efficient regulation by having Twister Money customers present receipts to an middleman, thus revealing their total transaction historical past to the middleman, however nonetheless having the ability to have privateness with respect to different public blockchain customers.”
The developer hopes this may help “begin a dialog” with U.S. regulators on how on-chain privateness could be preserved while limiting felony exercise by means of using ZK proofs.
Associated: On-chain privacy is key to the wider mass adoption of crypto
Soleimani’s try to create a crypto-friendly on-chain privateness answer comes after the U.S. Workplace of Overseas Asset Management (OFAC) sanctioned ETH and USDC addresses linked to Tornado Cash on Aug. 8 in response to a number of alleged thefts by North Korea’s Lazarus Group, who have been claimed to have routinely used the privateness mixer to protect its anonymity.
Shortly after the sanction on Aug. 10, Alexey Pertsev, the creator of Twister Money was arrested by authorities in the Netherlands and is at the moment going through a collection of cash laundering fees. He stays behind bars and his subsequent listening to will happen in late April.
