The Ethereum institutional privacy technology company EthSystems has officially launched and received strategic funding support from ecosystem backers such as Bitmine, Sharplink Gaming, Joe Lubin, and SNZ Holding.EthSystems focuses on developing privacy technologies for banks, asset management companies, and other regulated entities, enabling institutions to execute financial transactions on the Ethereum network at scale while protecting sensitive information such as transaction details and client identities.The company was founded by the core team of the Institutional Privacy Task Force (IPTF) of the Ethereum Foundation. The team has previously conducted a year-long open-source research and development publicly on the EthSystems website and has established partnerships with several central banks, regulatory agencies, large banks, and asset management institutions. EthSystems stated that while institutions have begun exploring stablecoins, tokenized assets, and Ethereum-based settlement solutions, large-scale adoption still faces privacy and compliance challenges.Financial institutions need more than just access to blockchain networks; they require a complete infrastructure that meets business confidentiality protection, regulatory requirements, and compatibility with existing financial systems. The goal is to create a "selective disclosure" privacy architecture that allows transaction participants to view only the information they are authorized to access, while retaining the core advantages of Ethereum's decentralization, security, and openness, and complementing two other organizations: Ethlabs, which focuses on the research and development of Ethereum's core protocol and infrastructure; Ethereum Institutional, responsible for institutional collaboration, education, market research, and ecosystem coordination; and EthSystems, which focuses on application layer technology, transforming institutional needs into practical privacy protocols and financial systems.

According to Bitcoin.com, the European Parliament passed the resolution to advance the digital euro with 416 votes in favor, 169 against, and 22 abstentions, entering a critical phase of negotiations with member states. This currency was first proposed in 2023, aiming to maintain European monetary sovereignty and provide citizens with digital cash.Negotiation representative Fernando Navarrete Rojas emphasized that the digital euro will "complement rather than replace cash," and will provide free basic accounts and holding limits to protect the financial system. The European Central Bank has previously established partnerships with major European payment standard providers, using it as a tool to counter the growing influence of private currencies such as stablecoins. European Central Bank Executive Board member Piero Cipollone stated that the digital euro will "reduce Europe's dependence on external providers."

Ethereum co-founder Vitalik Buterin published the proposal "The Extremely Lean Chain," demonstrating how to radically compress the state requirements of the Ethereum consensus chain in the context of the "Lean" upgrade. This plan shifts responsibility to validators, who manage and periodically prove their state through ZK proofs, thereby eliminating the processing burden for each epoch and potentially supporting millions of validators.The core mechanisms include: removing the validator public keys from the on-chain state, storing only the deposit tree index; canceling real-time reward and penalty processing, with validators generating daily STARK proofs of their participation and updating balances; completely re-randomizing validator identities daily, achieving strong anonymity through ZK-STARK, with withdrawal addresses exposed only at the time of withdrawal and not publicly linked to deposits or on-chain activities. Vitalik stated that based on upgrades such as single-slot finality and quantum-resistant signature aggregation, the state requirement per validator could be compressed from approximately 180 bytes to 6 bytes. The daily proof cost for a single validator requires processing about 5400 Merkle branches, which can be completed within 1 hour on ordinary hardware, and the on-chain burden can be reduced through aggregated proofs. Additionally, this design can achieve a "virtually free" single secret leader election function, with 1 day as the conservative cycle length and 1 hour as the lower limit.

According to Jinshi reports, Federal Reserve's Williams stated that if the Middle East war can be resolved quickly, it will help reduce inflationary pressures.

StarkWare launches the STRK20 privacy token standard, allowing users to hide on-chain balances and transaction details while maintaining compliance checks and regulatory disclosure mechanisms.

CZ Zhao shared his interview video on platform X, discussing the potential impact of quantum computing on the Bitcoin encryption system, including the threat to Satoshi Nakamoto's Bitcoin holdings. If future quantum attacks lead to the old encryption system being compromised, the community may face three options.The first is to "do nothing," allowing the relevant assets to be naturally transferred by attackers and create selling pressure, but ultimately it may lead to a redistribution back to the community;The second is to freeze or restrict relevant addresses and envision returning assets under verifiable identities, but he believes this path has technical and credibility issues after the encryption is compromised;The third is an intermediate solution such as "slowing down or delaying transfers," but it also has execution complexities.CZ also proposed a compromise idea: to set a time window through community governance, such as 6 to 12 months. If the funds in relevant early addresses have not moved, they would be locked through a network fork or protocol upgrade, permanently removing them from circulation, thus avoiding future concentrated theft by attackers that could create market selling pressure. He emphasized that such decisions should be determined by community voting and believes there is currently no perfect answer, but "not taking any action may become the worst outcome in the future," so mechanisms should be designed in advance to address potential quantum risks.

Hong Kong Exchanges and Clearing Limited (HKEX) and the Hong Kong Monetary Authority (HKMA) today announced the launch of a joint pilot project to explore new digital payment solutions for trading during after-hours sessions in the derivatives market. This pilot project aims to optimize Hong Kong's capital markets and meet the growing demand for after-hours trading sessions. HKEX and HKMA are studying the introduction of "digital Hong Kong dollar"—a wholesale central bank digital currency (CBDC) operating on a 24/7 model—for the payment of pre-paid margins during after-hours trading sessions, to enhance the risk management capabilities of the derivatives market outside of banking hours while maintaining existing operational processes.

Circle plans to release the Arc Privacy confidential smart contract engine, aimed at addressing the barriers to institutional adoption caused by the current blockchain's default complete transparency through "Opt-in Privacy." Arc Privacy will allow users and developers to selectively mask sensitive information in transactions and smart contracts based on actual needs, rather than forcing all data to be public. At the same time, it retains the authorized access required for compliance, auditing, and governance, achieving a balance between privacy and auditability.The engine supports the EVM environment and emphasizes composability, allowing developers to build multi-step private application processes in the Ethereum environment. The article lists several real business scenarios, including confidential salary payments, treasury fund transfers, tokenized asset management, confidential perpetual contract trading, and privacy lending.

According to Jinshi reports, Federal Reserve's Schmid stated that inflation remains too high, and this has been a struggle lasting five years, with the Federal Reserve still working to find solutions.

According to Bloomberg, European Central Bank Executive Board member Isabel Schnabel stated that stablecoins pose multiple risks to financial stability and monetary policy, and the best response from the European Central Bank is to ensure that public money continues to serve as the anchor of the system.She pointed out that while private monetary innovations like stablecoins can bring "significant benefits," they may also increase the risk of runs on the financial system, weaken the transmission effects of interest rate decisions, and reinforce the international dominance of the dollar. Schnabel emphasized that the European Central Bank's strategy relies on the digital euro as a retail central bank digital currency and tokenized central bank money as wholesale CBDC.She noted that many advantages of stablecoins stem from their underlying technology rather than the characteristics of the instruments themselves. The day before Schnabel's remarks, Federal Reserve Governor Waller stated that the global spread of stablecoins could expand the influence of U.S. central bank policies and questioned CBDCs, calling them "a stupid thing."

According to official news, the Resolv Foundation has released a complete recovery framework following the protocol security incident. Previously, on March 22, 2026, the protocol was attacked due to a security vulnerability, resulting in the illegal minting of USR tokens entering the market. The protocol subsequently suspended operations and entered recovery mode. Resolv stated that USR was designed as a "premium layer" stable asset backed by collateral, while RLP served as an "insurance layer" to absorb losses. According to the recovery plan, USR/wstUSR held before the attack will be exchanged for USDC at a 1:1 ratio, while USR purchased after the attack will be processed at a 1:0.5 USDC ratio; RLP holders will recover approximately 60%+, with part of the compensation distributed in the form of RESOLV tokens. The official compensation application window is open for three months.At the same time, Resolv announced the launch of a new business line called "Vault Street," managed by the Resolv Foundation, focusing on the distribution and structured yield products of tokenized real-world assets (RWA). The first product, primeUSD, has entered the private testing phase, open to professional institutional investors, allowing users to participate in leveraged U.S. Treasury yield strategies through stablecoins. Resolv stated that this product combines structured financing experience from traditional finance with on-chain DeFi infrastructure, aiming to build an institutional-level RWA yield distribution platform. In addition, the functionality of the RESOLV token remains unchanged, with staking and unstaking functions restored, and reward distribution resumed on May 26. Resolv emphasized that it will continue to promote the expansion of Vault Street products, upgrade security architecture, and build on-chain infrastructure for institutional-level assets, stating that "the phase from protocol launch to security incident has ended, and Vault Street will open a new chapter for Resolv."

According to Bloomberg, the rulings on controversial contracts on Polymarket are being dominated by a small number of UMA holders. Bloomberg's statistics show that among over 6,400 addresses that participated in Polymarket's controversial ruling votes over the past three years, only 9 large wallets contributed about half of the UMA voting power and sided with the winning side in almost all disputes.In April 2026, about 230 contracts with a total trading volume exceeding $1 billion entered the controversial ruling process, accounting for less than 1% of all contracts on Polymarket, but the frequency of disputes increased with the trading scale. Some traders criticized that this mechanism effectively grants anonymous whales "fact-determining power" driven by economic interests, while Polymarket and Risk Labs, responsible for UMA, had originally promised to improve the relevant processes, which has now been shelved.

Digital asset market infrastructure provider Prometheum recently launched Digital Brokerage Solutions, offering agency clearing, custody, and trading services for broker-dealers and registered investment advisors (RIA), enabling them to provide cryptocurrency assets and tokenized securities directly to clients through traditional brokerage accounts.Co-founder and co-CEO Aaron Kaplan stated that hundreds of billions of dollars in tokenized securities have been issued on-chain, but there is a lack of distribution channels to reach mainstream investors. He believes that the crypto industry has solved the tokenization issue but has not yet addressed the distribution problem, and that broker-dealer and RIA channels are key to achieving scalable reach to investors.

Enterprise blockchain infrastructure Antier Solutions announced the completion of a $3 million financing round, led by GVFL. The new funds will be used to support the construction of secure transactions, verifiable workflows, and institutional-grade blockchain infrastructure, expand deployments in the government and financial institutions (BFSI) sector, and grow business in the United States, Middle East, and Asia-Pacific markets.

According to Jinshi reports, Federal Reserve official Daly stated that the current monetary policy is "slightly tight." He pointed out that if the conflict between the United States and Iran is resolved, it will create downward pressure on inflation.

DeFi United announced a technical repair plan for the Kelp DAO rsETH cross-chain bridge vulnerability on Tuesday. Previously, attackers exploited a vulnerability in the LayerZero-driven Unichain to Ethereum bridge, releasing 116,500 rsETH by spoofing inbound packets, of which approximately 107,000 are currently still distributed as collateral across seven associated addresses in Aave and Compound.DeFi United stated that it has secured enough ETH commitments to restore the support for rsETH, which will be converted into rsETH in batches and injected into the bridge lock contract. LayerZero Labs pledged over 10,000 ETH on Tuesday to support the repair efforts. Regarding the liquidation of the attackers' positions, the alliance will execute controlled liquidations through Aave and Compound governance proposals, expecting to recover approximately 13,000 and 16,776 ETH, respectively.During the repair period, WETH and rsETH reserves on multiple chains will remain frozen. DeFi United also cautioned about execution risks, including governance approval progress, potential interference from attackers, and new security measures pending validation in the production environment.

Paul Frambot, co-founder and CEO of Morpho, tweeted that he has been in intensive contact with several large institutions over the past week to understand the current DeFi situation. The main conclusions are twofold:The interest of institutions in DeFi will not disappear, as the fund distributors will not leave. The massive assets under management (AUM), payment, and lending businesses are migrating en masse to on-chain, and fintech companies hope to fully go on-chain, leaving institutions with no choice.Nevertheless, institutions have completely lost trust in the liquidity pool model. They want to have control over the code, risk management, and compliance, allowing them to flexibly choose the necessary parts while accessing a globally compatible liquidity network.Paul Frambot believes that the commitment to open financial systems will not fail, as it will create tremendous value for all participants.

Solana's official article on the potential impact of quantum computing on blockchain reiterates that the quantum threat is still years away, but the Solana ecosystem has already conducted thorough research and technical preparations in advance.The independent verification client development teams Anza and Firedancer (which together represent a large portion of the network's staking share) have unanimously concluded after independent research that a compact signature scheme suitable for high-throughput blockchains is needed, and they have jointly selected the Falcon scheme. Both parties have published their initial implementation code on GitHub.In addition, the Solana Winternitz Vault developed by Blueshift has been operational in the ecosystem for over two years, providing a direct quantum-resistant path. Earlier this year, Google Quantum AI listed this Vault as a leading example of forward-looking post-quantum work in its white paper.Solana's current quantum roadmap includes ongoing quantum research and evaluation of Falcon and alternative solutions; adopting post-quantum solutions for new wallets when quantum becomes a credible threat; and migrating existing wallets to the selected solution. The official statement indicates that the migration work is manageable and can be completed quickly when the time comes, with network performance expected to remain largely unaffected.
