Financial Privacy in the Digital Era: A Regulatory Challenge

The US government's efforts to regulate the crypto industry have made significant progress in recent months. However, one critical area still needs attention: financial privacy. The current system is fragmented, with multiple agencies having different approaches and rules.

The Department of the Treasury, the Department of Justice, and the SEC all play a role in regulating financial privacy. But their differing views create uncertainty for businesses and consumers. For example, Treasury's 2019 guidance on non-custodial crypto services was later contradicted by the DOJ's enforcement against Tornado Cash.

Fortunately, modern cryptography offers solutions to these problems. Zero-knowledge proofs allow participants to prove compliance without revealing underlying data. This technology can enable fully private transactions on fully public blockchains.
