The Zcash Foundation officially announced the release of Zebra version 4.4.0. This update fixes multiple consensus-level critical security vulnerabilities and strongly recommends that all node operators upgrade immediately. This includes a denial-of-service vulnerability that can cause new blocks to stop being discovered permanently, consensus divergences caused by errors in block signature operation (sigops) counting, anomalies in the processing of transparent transaction signature hashes, and risks of memory allocation amplification attacks.The Zcash Foundation stated that some of these vulnerabilities could cause Zebra nodes to accept blocks that are rejected by zcashd, leading to chain forks. If not updated in a timely manner, nodes may face risks such as interruption in block discovery, consensus forks, and resource consumption amplification, and there are currently no alternative mitigation solutions.

Robert Hackett, head of special projects at a16z Crypto, pointed out that the term "stablecoin" is gradually losing its relevance. Stablecoins were originally born during a period of high volatility in the crypto market, hence the emphasis on the characteristic of "stability."However, with technological evolution, stability has become a foundational aspect evolving into global financial infrastructure. The focus of the crypto industry has shifted from "is it stable" to "what else can be built," with stability becoming a basic threshold rather than the innovation itself.Therefore, the term "stablecoin" seems more like a patch for an old problem rather than a definition of a new financial system. In the future, the concept of stablecoins may ultimately fade into broader expressions like "digital dollar" or "on-chain assets," or even fully integrate into the underlying financial system, much like how "electric light" replaced the concept of "electric illumination."

Miles Jennings, the policy head and general counsel of a16z Crypto, and others wrote "Getting prediction market regulation right," which points out that the current push by the Commodity Futures Trading Commission (CFTC) to reform the regulatory framework for prediction markets is at a critical juncture, as prediction markets are transitioning from niche products to important infrastructure.With the integration of AI and blockchain-driven new risk management models, prediction markets can enable AI agents to automatically hedge risks, adjust on-chain event contract positions in real-time, and play a core role in risk management, information aggregation, and authenticity judgment. a16z Crypto believes that if the regulatory framework is too conservative, it will limit the development potential of prediction markets. Therefore, they have submitted a comment letter providing opinions on key issues such as the application of statutory core principles and CFTC regulations in prediction markets, and public interest considerations related to event contracts. They also proposed five regulatory recommendations for prediction markets, including: the CFTC implementing unified regulatory authority over event contracts, optimizing contract dispute resolution mechanisms, strengthening monitoring of insider trading and market manipulation, re-evaluating "special rules," and exploring clearer compliance pathways for on-chain prediction markets.

The legislative process for the structure of the U.S. cryptocurrency market is accelerating, with Congress pushing for the earliest possible review stage. However, uncertainties remain regarding ethical issues and the cryptocurrency interests related to Donald Trump, which complicate the path forward.One of the main proponents, Senator Thom Tillis, stated that he has requested Senate Banking Committee Chairman Tim Scott to arrange hearings and advance the amendment and voting process, while also hoping to release a new version of the bill text before the review. However, Tillis emphasized that he would oppose the bill's passage if it does not include clear ethical provisions. With the midterm elections approaching, related ethical issues are expected to become a key focus for the Democratic Party.

Web3 asset data platform RootData released the progress data for the 2026 Q2 TGE. From the time distribution perspective, the crypto market is entering a concentrated release period for Q2 TGE, with market risk appetite and liquidity activity rebounding in sync. Among them, MegaETH has become the core anchor point of this window period. This project focuses on "ultra-high performance real-time execution" of EVM L2. After completing a $30 million financing, it officially TGE'd on April 30 and simultaneously launched on major exchanges such as Coinbase, Upbit, and Bithumb. According to the "Upcoming Issuance" section data from RootData's market, TGE is showing characteristics of a "short-term concentrated explosion": on April 29, Gensyn completed its TGE, on the 30th, MegaETH and Real Finance TGE'd simultaneously, and on May 1, Kuvi followed closely with its launch. Avant is expected to push forward its TGE in the latter part of Q2. At the same time, Polymarket data also provided forward-looking signals: before June, it may enter a peak issuance interval. Dreamcash (64%), Arc (46%), and Oro (40%) are in the first tier and may form the core of the next liquidity competition. Overall, this round of Q2 TGE is not a confirmation signal for the market but rather the starting point for liquidity redistribution. The subsequent market strength will depend on the absorption capacity of the new supply and the degree of support from the project's fundamentals for valuation.

According to Jin Shi reports, Brian Jacobsen, chief economist at Annex Wealth Management in Menomonee Falls, Wisconsin, stated that it is not surprising to see divisions within the Federal Reserve, but the divisions being so apparent is surprising. He mentioned that if Powell's last meeting was like this, imagine how loud the opposing voices would be under Waller's leadership. Hawkish traces can be seen everywhere in the wording regarding high inflation, and some Federal Reserve officials believe that raising interest rates might solve the inflation problem, even if it means paying a price in the labor market.

The gaming public chain Ronin announced that it will migrate to Ethereum Layer 2 on May 12, during which there will be an approximately 10-hour downtime for on-chain operations. Normal operations will resume after the migration is completed, and its underlying architecture will be built on the OP Stack, with EigenDA integrated as the data availability layer.It is recommended that users unstake RON before the migration date, or the system will automatically unstake for users after the migration is completed. The core goal of this migration is to allow Ronin to leverage Ethereum's security, data availability, and finality capabilities, while injecting mature on-chain gaming infrastructure into the Ethereum ecosystem. As the underlying network for well-known on-chain games like Axie Infinity and Pixels, this move is seen as an important milestone in its ecological development.After the migration is completed, the annual inflation rate of RON will be reduced from over 20% to below 1%, and the treasury will gain continuous income from staking, Sequencer net revenue, and Marketplace fees (which will increase from 0.5% to 1.25%).

Web3 security company CertiK released the report "2026 Digital Asset Regulatory Status," systematically outlining global regulatory trends. The report indicates that by 2026, the regulatory frameworks in major jurisdictions will have basically been established, and the industry is entering a phase of full compliance. The report shows that anti-money laundering enforcement has replaced the definition of securities attributes as the primary regulatory risk, with global anti-money laundering-related fines exceeding $900 million in the first half of 2025, and transaction monitoring capabilities becoming a core compliance requirement.At the same time, smart contract security audits are evolving from industry best practices to entry requirements, becoming essential for license approval and token listings. Additionally, global stablecoin regulatory frameworks are becoming more consistent, generally establishing principles such as full reserves and licensed issuance; however, differences in cross-jurisdictional regulation still pose compliance challenges. The report points out that with regulatory convergence and strengthened enforcement, the industry has entered the "strong compliance era." CertiK states that the core issue facing enterprises is shifting from "Are we compliant?" to "Can we quickly build and implement compliance capabilities?" Licensing in multiple regions, investments in anti-money laundering, and ongoing security audits are becoming the foundational thresholds for institutional development.

According to CoinDesk, Strategy co-founder Michael Saylor stated "Winter's over" when Bitcoin was around $78,000. Analyst Mati Greenspan pointed out that the previous "flash crash" was more of a correction in a bull market, and he believes the bottom for Bitcoin has been reached, with the next phase of growth driven by "national-level adoption," including central banks incorporating BTC into reserves alongside gold.The report mentioned that the U.S. government currently holds about 300,000 BTC and is discussing the establishment of a strategic Bitcoin reserve; El Salvador continues to purchase daily, and Bitcoin has also been included in asset allocations by the UK government and some state-level pension funds in the U.S.

According to China News Weekly, a 19-year-old female college student from Guangdong was recently invited to Thailand to participate in the Water Splashing Festival. After landing, she was controlled and is suspected to have been sold to a Myanmar telecom fraud park near the Three Pagodas area on the Thailand-Myanmar border.Her family stated that the other party claimed to have purchased her for 29,000 U and then demanded a ransom of 30,000 U, equivalent

Vitalik Buterin posted on the X platform, stating that there is a significant risk associated with a single data source in light of the recent incident where weather sensors at Paris airport were interfered with, affecting the outcomes of prediction markets.He pointed out that for such data-driven prediction markets, at least the median of three independent data sources should be used as a reference to reduce the possibility of manipulation.

The cryptocurrency trading platform HTX released the "USDD In-Depth Research Report," which points out that the decentralized stablecoin USDD has completed a key transformation into an over-collateralized stablecoin, and its overall maturity has entered the same competitive range as DAI. Relying on the advantages of the TRON ecosystem and multi-chain native deployment, USDD is gradually becoming a new generation of decentralized stablecoin infrastructure that combines stability and yield capability.The report provides a comprehensive and in-depth analysis of USDD from multiple dimensions, including core competitive advantages, yield ecosystem panorama, security system, and competitive landscape, and highly affirms its construction of a sustainable yield ecosystem and differentiated advantages.

According to CertiK senior blockchain investigator Natalie Newson, real-time deepfakes, phishing, supply chain attacks, and cross-chain vulnerabilities will be the main sources of crypto hacking attacks.To date, the industry has lost over $600 million due to hacking attacks, including the $293 million vulnerability incident at Kelp DAO and the $280 million theft incident at Drift Protocol, both of which are related to North Korean hacker groups. Newson warned that the accelerated development of AI will make attack methods more complex, including more realistic deepfakes, autonomous attack agents, and "agent AI" that can automatically scan for vulnerabilities in smart contracts, but AI can also serve as a defense tool. CertiK advises investors to verify the authenticity of URLs and use cold wallets to store assets to reduce risk.

ChainCatcher reported live that Justin Sun, the founder of TRON, shared a keynote speech titled "From TRON to B.AI: Infrastructure as the Game-Changer in the AI Era" at this year's 2026 Hong Kong Web3 Carnival.He introduced that TRON currently supports about 86.4 billion USDT, with other stablecoins bringing the total close to 90 billion dollars, and the global account number has reached 376 million, making it one of the largest stablecoin settlement networks in the world. He emphasized that the most important aspects of financial services are stability and security, rather than being cheap.He pointed out that the existing payment systems are not compatible with AI, as bank accounts require human identity for opening, and each payment needs manual authorization, which cannot support high-frequency decision-making by AI. B.AI is building the underlying financial infrastructure for AI agents, allowing each AI to operate without becoming human, managing keys and on-chain wallets through cryptography to complete payments, and can anonymously call the world's most

ChainCatcher reported live that Adeniyi Abiodun, co-founder and Chief Product Officer of Mysten Labs, delivered a keynote speech at the 2026 Hong Kong Web3 Carnival. He stated that the core team members come from Facebook and were responsible for launching the global payment network Libra, aiming to make fund transfers as simple as sending messages. He announced that Sui will be the first high-speed public blockchain to achieve zero transaction fees for transfers across the network, regardless of the transfer amount ranging from $0.0005 to $1 billion, covering all stablecoins such as USDC, USDT, and Sui Dollar.In terms of privacy, Sui will provide bank-grade on-chain privacy, utilizing advanced cryptography to ensure that transaction history and balances are not visible to third parties, while fully compliant with regulatory requirements. Regarding yields, he introduced the Sui Dollar launched in collaboration with Stripe, which generates approximately 3.5% returns that will be directly reinvested into the network ecosystem and users, rather than flowing to intermediaries.He also announced the launch of the Bitcoin DeFi protocol Hashi aimed at institutions, allowing sovereign wealth funds, hedge funds, and ETF holders to deploy Bitcoin into DeFi for yields without triggering taxable events, supported by legal opinions from top U.S. law firm Fenwick & West. Additionally, Sui's on-chain deep order book DeepBook supports large transactions with extremely low slippage for instant on-chain exchanges between assets such as BTC, gold, USD, and EUR.In the AI agent economy, he pointed out that Stripe estimates a need for processing capacity of 1 billion transactions per second in the future, while Sui employs a horizontally scalable architecture similar to that of Google Search and Facebook infrastructure, capable of scaling on demand to millions or even tens of millions of TPS. The full-stack atomic composability provided by Sui is its core differentiated advantage, allowing agents to execute multiple cross-application transactions simultaneously and settle them in one go, which cannot be achieved on AWS, Google, or any existing Web3 platform. He also announced a partnership with RedotPay, enabling users to spend Sui Dollars at over 130 million merchants worldwide and positioning Sui as an alternative to SWIFT.
