The United States should lead the development of central bank digital currencies (CBDCs) away from being “surveillance coins” and toward being “freedom coins,” says the former chair of the Commodity Futures Trading Commission.

In a March 13 op-ed in The Hill, Christopher Giancarlo said that the U.S. “must influence” CBDC development toward protecting “democratic values like freedom of speech and the right to privacy,” leveraging current technology used by some cryptocurrency protocols.

Nicknamed “Crypto Dad” for his pro-crypto outlook, Giancarlo is co-founder of the Digital Dollar Project, which focuses on researching the implications of a U.S. CBDC. He elaborated on his concerns about privacy in a March 1 report for policy think tank the American Enterprise Institute that he co-authored with API fellow Jim Harper. 

He said the U.S. must advocate for a “freedom coin” — a CBDC that guarantees a high level of privacy.

Giancarlo and Harper argued in the paper that CBDCs offer an opportunity “to reassess contemporary financial surveillance activities” and could possibly enhance constitutional protections.

To achieve this, a CBDC could take advantage of crypto technology, such as “zero-knowledge proofs, homomorphic encryption, and multiparty computation, that enable parties to prove an encrypted proposition is true without revealing the underlying information," they said.

These technologies would make “intelligent enforcement” of crime prevention possible, the authors argued.

First, the U.S. would have to reexamine current financial surveillance policies. The authors took issue specifically with one recent document published by the administration of U.S. President Joe Biden:

“The White House Office of Science and Technology Policy’s (OSTP) recent Technical Evaluation for a U.S. Central Bank Digital Currency System shows that financial surveillance in the West is more like China’s than many would like to admit.”

The OSTP paper showed an “unwillingness to evolve beyond today’s constitutionally suspect financial surveillance system,” they said.

Giancarlo and Harper pointed to the OSTP’s proposed Anti-Money Laundering (AML) and Know Your Customer (KYC) measures as problematic, saying they allowed too much surveillance without probable cause.

If a CBDC's privacy is not guaranteed, there is a risk of it being used as it is in China, they argued.

There, the e-yuan “will allow the Chinese government to link political conformity to individual prosperity and relegate political dissenters to poverty” by making all transactions visible to the People’s Bank of China, they opined.

The authors’ thoughts have much in common with concerns expressed by U.S. Senator Tom Emmer, a vocal opponent of a U.S. CBDC who introduced the CBDC Anti-Surveillance Act in 2022.

Emmer has expressed concern over a CBDC that “tracks transaction level data down to the individual user” and can be programmed “to choke out politically unpopular activity.” Emmer is also co-chair of the U.S. Congressional Blockchain Caucus.
