Researchers Use Zero-Knowledge to Address Privacy, AML Concerns in Stablecoins

Researchers from German crypto blockchain-based payments fintech etonec and other organizations have proposed using zero-knowledge proofs to ensure regulatory compliance and privacy in stablecoins. They have created a design that allows fiat-based stablecoins to be used like cash, within limits.

The researchers’ design allows a number of limits, such as transaction limits, balance limits, and turnover limits and enables Anti-Money Laundering (AML) and Countering the Financing of Terrorism (CFT) compliance with the use of zero-knowledge proofs, particularly zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge). Below the preset limits, transactions would be invisible to third parties.

New Stablecoin Bill Introduced in US Senate to Regulate Dollar-Pegged Digital Assets

Senators Cynthia Lummis and Kirsten Gillibrand have proposed a new bill that aims to establish definitions for dollar-pegged digital assets and their issuers. The bill mandates that payment stablecoin issuers meet reserve and operational requirements, including creating subsidiaries specifically for issuing stablecoins. Additionally, stablecoin issuers must deal in dollar-backed tokens and ensure their tokens are fully backed by reserve assets. The proposed legislation seeks to define how stablecoins will operate in the US and would prohibit algorithmic stablecoins. There are ongoing discussions about attaching stablecoin legislation to a must-pass bill reauthorizing the Federal Aviation Administration, and Senator Sherrod Brown has indicated that specific safeguards must be included for the legislation to move forward.
