Canada Moves to Regulate Stablecoins in New Budget (Decrypt)
The Canadian government will introduce legislation to regulate the issuance of fiat-backed stablecoins in Canada. Under this framework, issuers will be required to maintain and manage adequate asset reserves, establish clear redemption policies, and implement robust risk management systems to protect consumers. The legislation ensures privacy safeguards for Canadians’ sensitive information and includes national security provisions to strengthen trust in the system, making stablecoins safe and secure for individuals and businesses. The Bank of Canada will administer these regulations, retaining $10 million over two years and subsequently $5 million annually, with costs offset by regulated stablecoin issuers. Additionally, the Retail Payment Activities Act will be amended to allow for the regulation of payment service providers conducting payment functions with stablecoins, reinforcing oversight and consumer protection in digital payments.

Amazon Sues to Stop Perplexity From Using AI Tool to Buy Stuff (Bloomberg)
Amazon has filed a lawsuit against Perplexity AI, demanding that the startup stop allowing its AI browser agent, Comet, to make purchases for users on Amazon’s platform. Amazon alleges that Perplexity violated its terms of service and committed computer fraud by failing to disclose when the AI agent was shopping on behalf of a real person. The dispute, which follows a cease-and-desist letter, highlights the growing tension over the use of agentic AI tools to automate complex online tasks such as shopping, and raises important questions about transparency, competition, and user choice in the evolving landscape of AI-powered web interactions. Perplexity responded by accusing Amazon of using bullying tactics to limit consumer choice and defend its own advertising business, arguing that third-party agents should be allowed to operate on equal footing with human users.

Anonymous Quantum Tokens with Classical Verification (arXiv)
Some Google researchers posted a paper on arXiv on the concept of single-use quantum tokens designed for secure, unforgeable, anonymous transactions with classical verification. Leveraging the quantum no-cloning theorem, which states that it is physically impossible to make an exact copy of an unknown quantum state, the authors develop tokens that are identically minted and provide strong privacy guarantees, including the ability of users to verify whether the issuing bank is tracking them through an audit process. The scheme theoretically supports classical verification, which means that all steps to prove the quantum token’s validity require only regular (non-quantum) memory and communication. However, given current technology limitations, only the issuer can check the validity of a token, in contrast to public key schemes, where any user can efficiently verify the tokens. [Source: arXiv]

I produce a monthly digest of digital fiat currency (DFC) developments exclusively for the official sector (e.g., central banks, ministries of finance and international financial institution (e.g., the BIS, IMF, OECD, World Bank)) plus academics and firms that are active in the DFC space (commercial banks, technology providers, consultants, etc.). (DFCs include central bank digital currency (CBDC), stablecoins and tokenized deposits.) It goes out via email on the first business day of every month, and if you’re interested in being on the mailing list, please email me at john@kiffmeister.com.
