Ameen Soleimani, co-founder of SpankChain and Reflex Labs, has recently hinted at a potential comeback for the Ethereum transaction mixer, Tornado Cash.

Soleimani’s tweet hinted at the involvement of Moloch DAO, which provides grants for Ethereum project development.

“I sincerely hope no one thought we were finished,” Soleimani said in his tweet.

Transaction mixing protocols, such as Tornado Cash, use various techniques to obfuscate the origin of cryptocurrency, which has attracted scrutiny from regulators.

Last year, the US Office of Foreign Assets Control accused Tornado Cash of enabling money laundering by North Korea-linked hacking group Lazarus.

Tornado Cash developer Alexey Pertsev was arrested last summer by Dutch authorities. Pertsev remains detained until a hearing scheduled for this April.

Despite its controversial history, the revival of Tornado Cash has gained attention from the crypto community, with many eager to see what improvements or changes will be made to the protocol.

With the involvement of Moloch DAO, it remains to be seen what new developments and innovations will be introduced.
