Țările de Jos arestează presupusul Tornado Cash Dev Days după sancțiunile SUA

Agenția olandeză de infracțiuni financiare FIOD a arestat miercuri un dezvoltator de 29 de ani la Amsterdam, pentru presupusă implicare în spălarea banilor prin intermediul mixerului criptografic Tornado Cash.

FIOD said a team began probing Tornado Cash in June. The investigation is led by the Public Prosecutor’s office.

„Nu sunt excluse mai multe arestări”, a spus Serviciul de Informații și Investigații Fiscale într-un declaraţie, adăugând că bărbatul suspect a fost adus în fața unui judecător.

Earlier this week, the US Treasury consacrat Tornado Cash addresses over allegations it laundered $7 billion worth of digital assets since it launched in 2019. That figure matches the total value of funds sent through Tornado Cash since its launch in February last year, per a Dune Analytics tablou de bord.

The platform’s web interface quickly went dark after major Ethereum node provider Infura pulled the plug, with its website is now offline. Code repository GitHub also shut down Tornado Cash’s account. Tornado Cash’s native token, TORN, has collapsed 40% since the sanctions were revealed, per CoinGecko.

“The online service [Tornado Cash] makes it possible to conceal the origin or destination of cryptocurrencies,” FIOD said. “The (criminal) origin of the cryptocurrencies is often not or hardly checked by such mixing services. Users of a mixing service mostly do this to increase their anonymity.”

Circle enforces Tornado Cash sanctions, leaving DeFi exposed

Tornado Cash’s protocol and its user interface are open source, meaning that anyone can contribute to its code. The Ethereum-powered project pitches itself as privacy-preserving, allowing users to commingle cryptocurrency inside smart contracts.

Once digital assets are withdrawn from Tornado Cash — depending on how long they spent in the mixing pool — their financial provenance should be too murky for onlookers to track, the idea goes.

Benign use cases for Tornado Cash exist. Following the US sanctions, Ethereum co-founder Vitalik Buterin, who was born in Russia, tweeter he’d used the to donate privately to pro-Ukraine outfits.

US authorities, alongside blockchain analytics units such as Chainalysis, believe the protocol a favorite among North Korean hacker unit Lazarus Group, which has allegedly used it to wash troves of crypto stolen in various hacking incidents, such as the Axie Infinite and Harmony Atacurile.

But enforcing the US’ Tornado Cash sanctions may prove challenging. In an apparent act of defiance, one anonymous user recently trimis small amounts of ether via the protocol to celebrities with known blockchain addresses, including Shaquille O’Neal and Jimmy Fallon.

Banning the wallets and open source repositories might send a signal, but doesn’t eliminate the capability, according to Travis Hoyt, NetSPI’s chief technology officer. He believes more bullet-proof solutions could emerge.

“The sanctions also highlight that the extent to which this can be enforced is limited by the reach of US law, and with the global and decentralized nature of the cryptocurrency space, there may still be plenty of additional avenues for criminals to pursue their goals that are out of reach,” Hoyt said.

DeFi apps, in step with Web2 companies such as GitHub, have been reviewing their exposure to Tornado Cash sanctions, particularly in relation to centralized stablecoins such as Circle’s USD coin (USDC).

Most of the freshly-banned addresses were USDC contracts linked to Tornado Cash. Circle obeyed the sanctions almost immediately by blacklisting more than 35 Ethereum addresses, freezing $70,000 in USDC.

The Treasury’s move has also opened the door for further protocols getting sanctioned, conform to MakerDAO co-founder Rune Christensen, who alongside several MakerDAO delegates, floated diversifying treasury funds backing its stablecoin DAI away from USDC altogether.

Crypto researcher and MakerDAO figure Mika Honkasalo told Blockworks earlier this week that the concern extends beyond MakerDAO. Any DeFi protocol with exposure to USDC, such as automated money market Aave, is technically vulnerable to the same treatment.
