A former Twister Money developer claims to be constructing a brand new crypto mixing service that goals to resolve a “crucial 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 “crucial flaw” with Twister Money is that customers can’t show that they’re not related to North Korea’s Lazarus Group or any legal enterprise for that matter.

check out the demo, however please observe:
– that is experimental code

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

The developer hopes the answer will empower “the neighborhood to defend towards hackers abusing the anonymity units of sincere 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 device don’t must manually create their very own subset exclusion lists.
In making the case for on-chain privateness protocols, Soleimani cited what he described as an “glorious” 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 complete transaction historical past to the middleman, however nonetheless with the ability to have privateness with respect to different public blockchain customers.”
The developer hopes this will help “begin a dialog” with U.S. regulators on how on-chain privateness could be preserved while limiting legal exercise by means of using ZK proofs.
Associated: On-chain privateness is essential to the broader mass adoption of crypto
Soleimani’s try to create a crypto-friendly on-chain privateness resolution comes after the U.S. Workplace of Overseas Asset Management (OFAC) sanctioned ETH and USDC addresses linked to Twister Money on Aug. 8 in response to a number of alleged thefts by North Korea’s Lazarus Group, who had 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 within the Netherlands and is at the moment dealing with a collection of cash laundering costs. He stays behind bars and his subsequent listening to will happen in late April.
