Circle CEO responds to U.S. Treasury's ban on Tornado: Tensions between privacy and security
The rapid growth of open-source, self-running protocols is challenging policymakers around the world.

Yesterday, the U.S. Department of the Treasury requested sanctions on ETH addresses associated with Tornado Cash. As a U.S. financial institution regulated under the Bank Secrecy Act (BSA), Circle, together with our partner Coinbase, restricted USDC fund flows to and from these sanctioned addresses.
It is likely that nearly all regulated virtual asset service providers have also taken steps to block customer transactions with these addresses, as failure to do so could result in accusations of deliberately evading U.S. sanctions compliance obligations—potentially carrying penalties of up to 30 years in prison.
This regulatory intervention marks a significant threshold in internet history and in the history of decentralized blockchain finance: a major government forcing parties to completely block or restrict the operation of open-source software on the internet.
It raises critical questions about privacy, security, and the future of public, internet-based digital currencies. On policy matters, we’ve long acknowledged the tension between privacy and security—but yesterday, this was no longer an abstract concept.
In short, this is a pivotal moment. The crypto industry must intensify its focus on major policy issues related to financial privacy.
Cryptocurrencies and blockchain infrastructure promise an open internet of value exchange, challenging decades-old regulatory frameworks—including market structure, payment systems, custody and settlement, risk management, and of course, fundamental issues of privacy and security.
To date, policy efforts have largely focused on market regulation and stablecoins, while globally expanding anti-money laundering (AML) and counter-terrorism financing (CFT) controls on digital asset operators and intermediaries.
However, the rapid growth of open-source, self-executing protocols is challenging policymakers worldwide. If we don’t act now, the result will be even more aggressive enforcement actions by governments.
In the coming days, Circle will call on leaders across the crypto industry, associations, and protocol developers to come together to help advance legal frameworks and policies that protect user privacy and security, while developing financial integrity rules tailored to open-source protocols.
This is a crucial pillar in the fight to protect the future of DeFi and public, internet-based digital currencies. This isn’t about any single organization, nor does it represent one organization—it’s about everything we’ve collectively built and stand for, and the future we believe in.
