Aleo released the privacy stablecoin white paper "Stablecoin Privacy," stating that the privacy layer is the key infrastructure missing for blockchain payment rails to be adopted by mainstream institutions. Aleo indicated that as the GENIUS Act provides opportunities for the widespread adoption of stablecoins, the issue of permanently public transaction information on public blockchains may still hinder institutions from using stablecoins in scenarios such as payroll, fund management, and vendor payments.Aleo claims that existing solutions do not adequately meet the needs of institutions in terms of privacy protection and risk management. The white paper proposes a permissionless private stablecoin architecture based on Aleo, which introduces programmable risk mitigation mechanisms while protecting transaction privacy through zero-knowledge technology and programmable smart contracts, allowing institutions to conduct private transactions without sacrificing compliance and risk control.It is reported that the team members behind this white paper have long been dedicated to research at the intersection of cryptography, policy, and financial systems. Aleo's Global Policy Director Yaya J. Fanusie, member of the Crypto Innovation Council and former Global Financial Crimes Compliance Officer at Coinbase Valerie-Leila Jaber, and cryptographer and Johns Hopkins University Computer Science Professor Matthew Green possess rare practical experience in private payments, financial regulation, and zero-knowledge cryptography.

According to a report titled "Stablecoins: Waiting for Regulation" released by the UK House of Lords Financial Services Regulatory Committee, the global market capitalization of stablecoins has exceeded $310 billion, but the UK pound stablecoin market is still in its infancy, and the construction of the regulatory framework is clearly lagging behind the United States (GENIUS Act) and the European Union (MiCAR).The report criticizes several aspects of the current regulatory proposals from the UK Financial Conduct Authority (FCA) and the Bank of England, focusing on:• The Bank of England's requirement for systemic stablecoin issuers to deposit at least 40% of reserve assets in non-interest-bearing central bank deposits, which the industry believes will severely harm issuers' profitability and the international competitiveness of the UK market;• The proposed holding limits (individual £20,000, corporate £10 million) are considered extremely difficult to implement and may stifle the development of the pound stablecoin market;• The T+1 redemption requirement will impose a significant operational burden on issuers;• The Prudential Regulation Authority (PRA) restrictions on deposit-taking institutions issuing stablecoins under independent brands are deemed overly stringent.The report also acknowledges the liquidity support loan mechanism proposed by the Bank of England, considering it an innovative regulatory measure that surpasses other major jurisdictions. The committee calls on regulatory agencies to strictly adhere to the established timeline, ensuring that the complete regulatory framework comes into effect as scheduled on October 25, 2027, and recommends adopting a principle-based, technology-neutral regulatory approach to achieve a reasonable balance between financial stability and market innovation.

According to crypto journalist Eleanor Terrett, the final text of the compromise on Section 702 of the Foreign Intelligence Surveillance Act (FISA), proposed by Senate Intelligence Committee Chairman Tom Cotton, includes a Federal Reserve CBDC ban that was originally part of the housing bill. This text is expected to ultimately become law. Notably, the termination date of the ban has been moved up from December 31, 2030, to June 12, 2029.

According to The Block, U.S. Senators Bernie Sanders and Elizabeth Warren, along with Representative Robert Scott, sent a letter to the Department of Labor requesting the withdrawal of a proposed rule that would allow 401(k) retirement plans to include alternative assets such as cryptocurrencies. The lawmakers stated in the letter that the proposed rule would create a so-called safe harbor for fiduciaries offering alternative investments, which would strip retirement savers of long-standing investor protections and encourage the use of riskier, more complex, and expensive investments.The Department of Labor announced the proposed rule in March, providing guidance steps for 401(k) plan managers to include alternative assets (including private equity, real estate, and digital assets) in their portfolios. Lawmakers expressed concerns about the volatility of digital assets and cited a Federal Bureau of Investigation report indicating that crypto-related fraud losses could exceed a record $11 billion in 2025. They also pointed out the Trump family's conflicts of interest in the crypto space, stating that the Department of Labor's proposed rule could enhance the president's interests at the expense of ordinary workers and retirees.

According to The Defiant, Ethereum researchers Thomas Coratger, Justin Drake, and others released a proposal on June 1 at the Ethereum research forum, planning to establish a dedicated XMSS public key registry as the first concrete protocol upgrade for Ethereum's migration to post-quantum cryptography.This registry allows approximately 1 million validators to pre-register quantum-safe XMSS keys before the full switch to the BLS signature system, serving as an important "preheating phase" to reduce the impact of the subsequent switch on network stability. This proposal has been included in the Ethereum Foundation's protocol team's Strawmap roadmap, marking the first protocol fork on that roadmap.

Vitalik Buterin once again proposed the concept of "synthetic stable assets," stating that the object of stability anchoring does not necessarily have to be the US dollar. He indicated that the core demand of users for stablecoins is price stability for future expenditures, but if the crypto ecosystem is built on US dollar-backed stablecoins, it is difficult to claim true decentralization.

The Liberal Democratic Party's Blockchain Promotion Parliamentary Alliance in Japan submitted a policy proposal to Finance Minister Katsuyuki Kitayama, calling for the clear inclusion of blockchain and Web3 in the national strategy. The proposal covers multiple areas including tax reform, cryptocurrency ETFs, leveraged trading regulation, responses to unregistered operators, cryptocurrency strategy, and trade logistics. Among them, the proposal suggests further research on the choice mechanism for "declaration separation taxation" and "withholding separation taxation" for crypto assets, and explores the tax treatment methods for exchanges and inheritance of crypto assets.In terms of derivatives regulation, the proposal believes that the current 2x leverage limit for individual cryptocurrency trading is too low and suggests gradually increasing the leverage level in conjunction with margin management systems. At the same time, the proposal also calls for a clear positioning of the cryptocurrency ETF system and strengthening law enforcement cooperation with overseas regulatory agencies. Katsuyuki Kitayama stated that he will actively promote the construction of related systems, including facilitating the implementation of cryptocurrency ETFs and researching a new tax system to be implemented in January 2028.

According to Bloomberg, the White House is reviewing early proposals from the U.S. SEC and CFTC regarding the re-examination of swaps and security swap reporting requirements, which are currently in the pre-rule stage. The two regulatory agencies plan to solicit public opinions before formally drafting regulatory details. The current reporting rules for swaps and security swaps in the U.S. are not unified, and some existing compliance exemption policies will expire in 2029.The International Swaps and Derivatives Association and the Securities Industry and Financial Markets Association jointly sent a letter last month urging regulators to unify the data reporting standards for the two types of products, while ICE Trade Vault LLC made a similar request. The CFTC stated that this work is being carried out jointly by the two agencies, and the SEC chairman has arranged for personnel to establish a unified reporting system during the industry conference in March. The new regulations will require two rounds of agency voting and public consultation before implementation.

According to CNN, officials stated that after meeting with advisors on Friday, Trump made modifications to the proposed agreement with Iran, which will extend the negotiation process by another week. The specific modifications requested by Trump are unclear, but officials indicated that the president insists on including tougher language regarding Iran's nuclear commitments and guarantees for the reopening of the Strait of Hormuz. There are also concerns about the economic relief measures that the agreement might provide to Iran.Additionally, Trump previously stated that the U.S. would take over and destroy Iran's stockpile of highly enriched uranium, and he mentioned that the agreement does not involve any exchange of funds. However, the Iranian side stated that the current negotiations do not involve details of the nuclear program and insists that any agreement must include arrangements related to funding. It remains unclear how these differences will be resolved as both sides continue to bargain over the wording of the agreement.
