According to The Block, the Sui Foundation released an incident analysis report on the recent three interruptions of the mainnet, attributing the three network outages that occurred last Thursday and Friday to two independent vulnerabilities introduced by the v1.72 version upgrade. The first interruption lasted about six and a half hours, while the second and third occurred on Friday morning and afternoon, respectively.The first two interruptions were caused by the "address balance" feature introduced in v1.72, which exposed flaws in the transaction fee deduction method. When a transaction was canceled due to insufficient funds, the network would still spend those funds, resulting in a negative balance that caused the validation node reconciliation process to crash. The foundation acknowledged that the temporary fix pushed urgently on Thursday carried known interruption risks, and the team accepted this risk to quickly restore on-chain services, which led to another network interruption on Friday morning.The third interruption was triggered by another undisclosed random state vulnerability, occurring when the validation nodes restarted to install the fix patch. Sui stated that user funds were never at risk, that both vulnerabilities have been fixed, and that a mechanism to forcibly terminate stalled epochs has been established. The foundation also mentioned that AI agents with access to its production systems significantly accelerated the diagnostic process.

According to The Block, the U.S. SEC has filed a lawsuit in the federal court in Houston, accusing Nathan Fuller, a resident of Cypress, Texas, of operating a cryptocurrency scam project involving up to $12.3 million, which used fraudulent artificial intelligence trading bots to defraud investors.Nathan Fuller told investors that his proprietary AI-based bot could automatically scan cryptocurrency trading platforms, capturing small price gaps through high-frequency arbitrage, and promised returns of 40% to 50% within 30 to 45 days. Some investors were even told they could receive guaranteed returns of over 100% within 21 days.The SEC stated that Nathan Fuller, founder and sole member of Privvy Investments LLC, raised these funds from approximately 150 investors located in nine states and two foreign countries between October 2022 and mid-2024. He also conducted business under the alias "Gateway Digital Investments."It is alleged that only about 3% of the funds were actually used for cryptocurrency trading, while Fuller personally siphoned off at least $6.2 million and paid approximately $5.5 million to early investors in a manner similar to a Ponzi scheme.

Sui stated on platform X that the mainnet has been restored and transactions are proceeding normally. During the deployment of the long-term repair plan yesterday, the end of the epoch was triggered, causing a pause. When the validating nodes restarted to deploy the new binary files, the random number initializer that runs at the beginning of each epoch could not complete because its quorum threshold was higher than the Sui consensus mechanism. After the validating nodes restarted, there was a potential vulnerability in the fault state preservation mechanism, which prevented the network from completing the transition to the next epoch. Currently, the validating nodes have implemented a fix that addresses the underlying vulnerability and the affected epoch, and network activity has resumed.

Sui stated on platform X that due to issues during the epoch change, the Sui mainnet has stopped accepting user transactions. The validator nodes are still running and creating system transactions, but currently cannot accept user transactions. The Sui core team is investigating this issue and will release updates immediately.

According to the official announcement from Sui Network, the Sui mainnet has resumed normal operation, and transaction processing and network activity have both returned to normal. The official disclosure states that the two network outages that occurred yesterday and the day before were related to an interaction issue between the "Address Balances" feature introduced in version 1.72 and the Gas billing logic. The Sui core team indicated that the fix deployed yesterday was only a temporary measure aimed at quickly restoring network operation, but this solution carried a known and low-probability risk of outage. Today, the network triggered a variant of the known issue, causing the mainnet to pause again. Currently, the validators have completed the deployment of a long-term fix, and the official claims that the known issues caused by the original vulnerability have been thoroughly resolved, with the network now operating normally. The Sui team stated that they will release a more detailed incident review report in the future, explaining the cause of the failure and the repair process.

The U.S. Commodity Futures Trading Commission (CFTC) has jointly issued staff guidance from its divisions of Market Oversight, Clearing, and Risk, addressing regulatory expectations and compliance requirements for the increasingly prevalent 24/7 trading, clearing, and settlement models, encouraging market innovation while ensuring compliance.The guidance emphasizes that regulated trading platforms, swap execution facilities, derivatives clearing organizations, and futures brokers must comply with the Commodity Exchange Act (CEA) and related regulatory rules when expanding around-the-clock trading, and must proactively assess risk management and operational arrangements.The CFTC points out that the adaptability of different asset classes to 24/7 trading varies, with derivatives related to crypto assets being more suitable for around-the-clock trading and clearing due to their digital infrastructure and global continuous trading characteristics; whereas traditional commodity derivatives like agricultural products may not be suitable for full 24/7 operation due to their regional and trading structure characteristics.CFTC staff stated that relevant institutions should ensure compliance with regulatory frameworks and risk control requirements while promoting the continuous evolution of the market to support "responsible market innovation."

According to Cointelegraph, plaintiff Noah Doe and two limited liability companies from Wyoming filed a lawsuit in New York, USA, on May 1, seeking a court ruling on their ownership of 39,069 dormant Bitcoin addresses, citing New York State's lost property law, claiming that the relevant addresses' holdings constitute legally "abandoned property."The addresses involved include those starting with "12c6D" associated with Satoshi Nakamoto and those starting with "1Feex" linked to the Mt. Gox hack. According to estimates by Timechain Index founder, the listed addresses hold approximately 3.7 million BTC, valued at around $28.5 billion.However, Noveleader, chief research analyst at investment research firm Castle Labs, pointed out that even if the court rules in favor of the plaintiffs, it would only be symbolic, as the Bitcoin network itself does not have a mechanism for reallocating funds without private keys. Additionally, the plaintiffs sent legal notices to P2PKH format addresses, while the involved BTC is actually stored in P2PK scripts. The analyst believes this move is "structurally flawed," which could render the abandonment notice procedure itself invalid.

The Sui mainnet officially launched the protocol-level stablecoin zero Gas transfer feature on May 20, supporting 7 types of assets including USDC, allowing users to complete transfers for free without holding SUI.In addition, the Premium Exchange incubated by NAVI Protocol is expected to officially go live on May 26 with its new system. These two developments optimize the trading experience from both the underlying protocol and application layer, further lowering the user entry threshold and promoting the development of the Sui ecosystem.

According to official news, Sui has announced the launch of the "Gas-Free Stablecoin Transfer" feature, allowing users and businesses to conduct peer-to-peer stablecoin transfers on the network without paying Gas fees or needing to hold additional SUI token balances. This means that the transaction fee for stablecoin transfers on the Sui network has officially dropped to $0. This feature is supported by Fireblocks and has been gradually rolled out on the Sui mainnet. This upgrade supports various stablecoins, including USDsui, SuiUSDe, AUSD, FDUSD, USDB, USDC, and USDY.Adeniyi Abiodun, co-founder of Sui and CPO of Mysten Labs, stated that stablecoins are becoming the core infrastructure of global finance, but users still need to manage Gas tokens separately, which increases complexity. The Gas-Free Transfer feature will remove this barrier, making on-chain payments simpler, more predictable, and easier to adopt.This feature is based on the new account balance system Address Balances launched simultaneously by Sui, which simplifies the on-chain storage and transfer process of funds while maintaining high performance and scalability. Since August 2025, the total amount of stablecoin transfers on the Sui network has exceeded $1 trillion. The official statement indicates that this upgrade will further promote Sui as the core stablecoin infrastructure for enterprise payments, fintech, and AI Agent automated payment scenarios.

Documents from the U.S. Department of Justice show that Trump has reached an unusual settlement agreement with the federal government, terminating a $10 billion lawsuit filed by him and his businesses against the Internal Revenue Service (IRS), and further expanding the relevant terms.The agreement states that the IRS will be "permanently prohibited" from investigating or continuing existing audits related to tax returns previously submitted by Trump, his businesses, and family members. The Department of Justice stated that this restriction only applies to the scope of existing audits.Meanwhile, the U.S. government has agreed to establish a "Deweaponization Fund" of up to $1.8 billion to compensate individuals or groups claiming to have been improperly treated during government investigations. This arrangement has been criticized by some Democratic lawmakers as a "disguised transfer of benefits," and has also raised questions within the Republican Party.Former IRS Commissioner pointed out that there has never been a precedent showing that the tax agency would permanently waive its right to review the historical filings of specific individuals or businesses, emphasizing that tax enforcement principles should remain consistent for all taxpayers. The Senate indicated that there are still many unresolved issues with this agreement, which is expected to continue to spark political controversy and regulatory discussions.

According to Hong Kong's East Network, a 34-year-old man from the mainland traveled to Hong Kong with a two-way permit. During his time there, he reportedly lost about 500,000 yuan on a cryptocurrency platform and, feeling frustrated, expressed suicidal tendencies on social media and planned to go to Hong Kong.Law enforcement agencies launched an investigation after receiving relevant information and intercepted the man at around 12:30 PM on May 14 at a fast-food restaurant on Admiralty Road. A lighter and suspected gasoline were found on him. The police arrested him on suspicion of "possessing any item with the intent to destroy or damage property" and he is currently being detained for investigation.Reports indicate that no one was injured in the incident, and there was no need for evacuation at the scene. The man is said to have complained multiple times to the relevant platform about his investment losses but did not receive a satisfactory response.
