: Sui announced on the X platform that its mainnet has resumed normal operations, and transaction flow has stabilized. The official confirmed that both network outages yesterday and today were caused by an interaction issue between the Address Balances feature introduced in version 1.72 and the Gas billing logic. The fix deployed yesterday was a temporary measure aimed at quickly restoring network functionality, but it had a known issue with a "low probability of triggering an outage." Today, a variant of that issue was triggered on the mainnet, causing the network to pause again.Currently, validators have completed the deployment of a long-term fix. The official stated that the known issue has been thoroughly resolved, and network activity has fully recovered. The Sui team said a more detailed post-mortem report will be released subsequently.
Michael Saylor posted on platform X, stating that CFTC guidelines are driving the development of the Bitcoin capital market, including 24/7 trading, BTC collateral, perpetual futures, options, and regulated access. This will benefit BTC holders, power the MSTR engine, and support the development of STRC as Bitcoin-backed digital credit.
According to Forbes, Western Union will launch its stablecoin USDPT on the Solana blockchain in May 2026. Issued by Anchorage Digital Bank, USDPT will be accompanied by a digital asset network designed to connect crypto wallets and exchanges. Analysts note that this move represents Western Union’s deliberate disruption of its core profit model: traditionally, the company relies heavily on foreign exchange spreads in cross-border remittances, but near-instant settlement via stablecoins will render such spreads transparent and unsustainable. At the same time, Western Union must still bear substantial fixed costs associated with its extensive offline agent network—a burden absent from crypto-native remittance firms from day one. The company’s Q1 financial report already reflects mounting pressure, with net income halved year-on-year to $65 million.
private equity giants Apollo Global Management and Blackstone Group are bringing in more investors for a debt financing deal worth approximately $36 billion to help Anthropic build its artificial intelligence infrastructure.According to insiders, this debt financing will be used to purchase Google's custom TPU (Tensor Processing Unit) chips, which will then be leased by Anthropic. Broadcom, which assisted Google in developing the chip, will provide guarantees for the majority of this deal. This move is expected to become one of the largest private credit transactions in history and potentially the biggest debt financing deal for chips to date. The plan aims to leverage Broadcom's credit standing to provide computing power support for Anthropic.
Odaily News, the U.S. Commodity Futures Trading Commission (CFTC) Market Participants Division today issued an interpretive opinion and a "No-Action Letter" in response to an application from Coinbase Financial Markets, allowing it to offer trading services for certain digital commodity derivatives through its affiliated offshore trading platform, Deribit. CFTC staff confirmed that, based on the framework approved for Kalshi's BTCPERP contract on May 29, 2026, relevant crypto perpetual contracts can be classified as "foreign futures" as defined under Regulation 30.1.Simultaneously, under the fulfillment of specific conditions, the CFTC's Market Participants Division stated it does not recommend enforcement action against Coinbase Financial Markets. This allows Coinbase to transfer customer-held digital commodities and stablecoins, used as margin, to its affiliated offshore broker-dealer to support trading positions in foreign futures and options, even if the relevant offshore broker-dealer has the right to rehypothecate these assets.Analysts believe this statement further clarifies the classification path for crypto perpetual contracts within the U.S. regulatory framework and provides institutional space for compliant entities to access derivatives trading through offshore liquidity markets.
the U.S. Commodity Futures Trading Commission (CFTC) announced today that it has issued an approval order to KalshiEX, LLC, a designated contract market (DCM), allowing it to list the perpetual contract BTCPERP, which references the spot price of Bitcoin, for trading as a futures product. The contract was submitted for review on May 29, 2026, pursuant to CFTC Regulation 40.3.The CFTC reviewed the BTCPERP contract under Section 5c(c)(4) of the Commodity Exchange Act (CEA) and relevant regulations, confirming that it complies with the CEA and CFTC rules, including core principles applicable to DCMs. The approval order requires Kalshi to strictly adhere to the CEA and all relevant CFTC regulations when listing and maintaining the contract.The CFTC also noted that the perpetual contract structure is not suitable for all asset classes and encouraged market participants to voluntarily submit applications for perpetual contract approval under the 40.3 rulemaking for uncovered assets to ensure compliance and robust market development.
Coinbase has announced it has become the first and currently the only Futures Commission Merchant (FCM) regulated by the U.S. Commodity Futures Trading Commission (CFTC), providing U.S. clients with access to the global crypto derivatives market, including crypto perpetual contracts and options. Previously, U.S. institutions could only trade crypto products derived from domestic futures exchanges, lacking access to global markets.Previously, U.S. clients were unable to participate in such global markets through compliant channels and had to establish offshore entities to access liquidity, resulting in increased counterparty risk and duplicated infrastructure costs. Through a single CFTC-regulated FCM, Coinbase Financial Markets is opening compliant access to global crypto options and perpetual contracts for U.S. institutional clients, including connectivity to platforms like Deribit, whose Bitcoin options open interest exceeds $31 billion, accounting for the vast majority of the global options market.Institutional clients can begin onboarding immediately. Deribit options are now available via Coinbase Financial Markets, with perpetual contracts and additional collateral types to be rolled out gradually. Broader access for retail clients is also in the pipeline.This move means that U.S. clients can finally participate in the world's largest and most liquid crypto derivatives market through a single, regulated channel, providing institutional investors with a more complete and compliant trading environment while reducing cross-border operations and complexity.
Binance has posted a teaser on X platform, announcing that it will reveal a new product on June 1.
According to CoinDesk, the U.S. Commodity Futures Trading Commission (CFTC) approved, for the first time on May 29 local time, a regulated exchange to list and trade Bitcoin perpetual futures contracts (“Perps”), marking the first such case in U.S. regulatory history. CFTC Chair Mike Selig characterized this move as a “significant milestone,” stating that perpetual contracts serve as foundational risk-management and price-discovery tools in global crypto-asset markets, and that the CFTC will provide an actionable regulatory framework for such contracts while restricting excessive leverage and systemic risk. Previously, perpetual contract trading had long migrated to non-U.S. jurisdictions due to the absence of regulatory oversight. The CFTC has not yet disclosed the names of the first batch of approved exchanges, and this policy has not yet been elevated to the level of formal regulation—meaning it remains subject to potential reversal in the future.
the U.S. Commodity Futures Trading Commission (CFTC) departments, including Market Oversight, Clearing and Risk, jointly issued staff guidance outlining regulatory expectations and compliance requirements for the growing 24/7 trading, clearing, and settlement model in the markets, encouraging market innovation while ensuring compliance.The guidance emphasizes that regulated trading platforms, swap execution facilities, derivatives clearing organizations, and futures commission merchants must comply with the Commodity Exchange Act (CEA) and relevant regulatory rules when expanding to 24/7 trading, and must proactively assess risk management and operational arrangements.The CFTC noted that different asset classes have varying suitability for 24/7 trading. Derivatives related to crypto assets, due to their digital infrastructure and global continuous trading characteristics, are more suitable for around-the-clock trading and clearing. In contrast, traditional commodity derivatives such as agricultural products, due to their regional and trading structure characteristics, may not be fully suited for 24/7 operations.CFTC staff stated that relevant institutions should ensure they meet the regulatory framework and risk control requirements while promoting continuous market evolution, in order to support "responsible market innovation."
: The Zcash Foundation has released version 4.5.0 of its node client, Zebra. This update includes multiple security fixes, addressing a critical consensus vulnerability and several high-severity Denial of Service (DoS) issues. All node operators are strongly urged to upgrade immediately.Key fixes in this release include a sigop counting error in P2SH script parsing (which could cause a consensus fork with zcashd), a logic flaw in NU5 block validation caching, a crash risk related to transparent address balance overflow, along with multiple crash and resource exhaustion vulnerabilities in RPC interfaces and mempool processing. The Foundation stated that some vulnerabilities could be exploited by malicious nodes, leading to node stalls, restart loops, or even permanent stoppage.Additionally, this version adds support for ZIP-213 (enabling shielded coinbase outputs to Sapling) and optimizes network performance and security boundaries. This includes limiting resource allocation during the pre-handshake phase, fixing risks related to multi-threaded queue abuse, and enhancing the misbehavior scoring mechanism.The Zcash Foundation stated that this update addresses over 80 security reports from the ZCG Vulnerability Disclosure Program (spanning April to May 2026), covering multiple layers including consensus security, memory management, RPC processing, and the P2P network attack surface. Officials emphasized that there is no alternative to this upgrade; upgrading is the only way to ensure nodes do not experience a chain split and remain secure.
Polymarket has stated the CLOB API is currently under maintenance, affecting trading functionality. The project team has identified the CLOB issue impacting trades and will restart the CLOB at 21:10 today to deploy the fix. During this period, there may be a brief window where order matching is temporarily unavailable or only limit orders are possible. Other services, including the website, Markets API, Polygon RPC, user authentication, and Sports API, will continue to operate normally.
the Polymarket development team stated, "The trading function is currently experiencing an anomaly. The team has identified the root cause and is deploying a fix. Real-time status updates can be viewed on the official status page."

Odaily Odaily News: Curated Exchange was officially launched on May 29, 2026. The project was initiated by open-source developers and research scholars. Its underlying theory is based on the academic paper "Decentralized Market Formation" published on SSRN in May this year. The core proposition is to establish a more effective mechanism for discovering, screening, and selecting long-tail assets through a low-cost multi-exchange parallel structure.Any individual, community, or institution can deploy a dedicated vertical trading portal with zero barriers, screen assets, and earn fees. All Venues share the same underlying liquidity. Different from the centralized coin-listing decisions of CEXs and the non-screening mechanism of AMMs, DMF replaces capital access with cognitive access—Curators act as asset gatekeepers based on professional judgment rather than capital scale, ensuring that high-quality long-tail assets are systematically discovered through Curators with reputational constraints.Curated positions itself as a neutral infrastructure provider, avoiding commercial competition with ecosystem participants, and will fully open-source its code in the future. The testnet will be officially launched in June 2026.
Sui officially announced a network outage on its mainnet due to a vulnerability in the Gas billing logic of version 1.72, temporarily halting all transactions and on-chain activities.

Bloomberg Senior ETF Analyst Eric Balchunas posted on X platform, pointing out that Bitcoin's volatility and correlation are increasingly approaching the level of gold. This trend has been significantly underestimated during the current market adjustment and may be a positive signal amid recent market turbulence. Based on the 60-day historical volatility comparison data of IBIT and the gold ETF (GLD) since their launch, Bitcoin's volatility structure is gradually converging with gold, indicating that its asset characteristics may be changing.Eric Balchunas added that despite the volatile market environment, the BlackRock Bitcoin Spot ETF (IBIT) has continued to outperform U.S. stocks since the escalation of the Iran conflict and has achieved more than double the excess returns compared to the S&P 500 ETF (SPY) since the approval of BlackRock's ETFs.
