Litecoin disclosed in a post on platform X that a recent zero-day vulnerability had caused a DoS attack, affecting the operation of major mining pools. Mining nodes that were not updated allowed an invalid MWEB (MimbleWimble Extension Block) transaction to be executed, enabling the related tokens to be withdrawn to a third-party DEX.The Litecoin network rolled back these invalid transactions through a reorganization (reorg) of 13 blocks, confirming that they would not be included in the main chain. All valid transactions during this period were unaffected, and the vulnerability has been completely fixed, with network operations restored to normal.

According to The Block, AWS Marketplace has integrated data services such as Chainlink's Data Feeds, Data Streams, and Proof of Reserve, supporting developers in connecting AWS's computing, storage, database, and API capabilities with blockchain smart contracts.AWS stated that the Chainlink oracle infrastructure provides a secure two-way connection between AWS resources and on-chain smart contracts, making it easier for institutions to develop applications that interact with tokenized assets and smart contracts in a familiar AWS environment.

According to Bloomberg, cryptocurrency venture capital firm Blockchain Capital is simultaneously raising two new funds, with a total target size of $700 million, namely its seventh early-stage fund and its second growth fund.Insiders revealed that the firm has begun deploying some of the newly raised capital, and the entire financing round is expected to be completed within five to six months.

According to a Bloomberg report citing Jefferies, a hacker attack on small crypto projects over the weekend, involving nearly $300 million, and the subsequent $10 billion fund run at the largest decentralized lending platform (the KelpDAO and Aave incident), may weaken Wall Street's interest in blockchain technology.Andrew Moss, an analyst at Jefferies' digital asset research team, pointed out that over the past year, banks, asset management companies, and payment institutions have been developing blockchain products similar to the technology system exploited by North Korean hackers. The report suggests that while such incidents are unlikely to directly impact traditional financial markets, it warns that traditional financial institutions may pause related processes and reassess risks before further advancing blockchain business.

According to BeInCrypto, Mastercard has joined the Blockchain Security Standards Committee (BSSC) as a charter-level member, collaborating with members such as Coinbase, Fireblocks, Anchorage Digital, and BitGo to develop a security framework for blockchain networks and tokenized assets.Mastercard will also join a working group focused on security and privacy guidelines, with Claire Le Gal from the security solutions department, responsible for fraud prevention, cyber resilience, disputes, and threat intelligence, representing Mastercard on the BSSC board. The executive director of BSSC stated that Mastercard's payment experience is of significant value in establishing robust blockchain security rules. Mastercard has launched multi-token networks and crypto credential products aimed at embedding trust in blockchain and tokenized infrastructure.

The "Quantum Computing and Blockchain Independent Advisory Committee" established by Coinbase has released its first position paper. The core conclusion of this position paper is that the core infrastructure of Bitcoin is fundamentally secure. Quantum computing does not pose a substantial threat to Bitcoin mining, hash functions, and the historical records of the blockchain. The real vulnerability lies at the wallet level, and Ethereum has laid out a clear roadmap to address this issue in the near future.Previously, Coinbase announced the establishment of the Quantum Computing and Blockchain Independent Advisory Committee in January this year, with committee members including researchers from Stanford University, the University of Texas at Austin, and the Ethereum Foundation.

Bloomberg cited a report from Jefferies LLC stating that a hacker attack over the weekend that siphoned nearly $300 million from a small crypto project, along with the resulting $10 billion fund run at the largest decentralized lending platform, may slow Wall Street's interest in blockchain technology.Andrew Moss, an analyst at Jefferies' digital asset research team, pointed out that banks, asset management companies, and payment institutions have been developing blockchain products similar to the technology systems exploited by North Korean hackers over the past year.While the report believes this incident is unlikely to impact traditional financial markets, it warns that traditional financial institutions may pause and reassess the associated risks before further advancing their blockchain initiatives.

According to BBX data, yesterday Cantor Fitzgerald raised the target prices for multiple cryptocurrency concept stocks on the same day, but stock prices remained generally under pressure. The core dynamics are as follows:Cantor Fitzgerald analyst Ramsey El-Assal released a research report on April 21, maintaining an "Overweight" rating for Strategy, Inc. (NASDAQ: $MSTR), Robinhood Markets, Inc. (NASDAQ: $HOOD), and Block, Inc. (NYSE: $XYZ), and raised the target prices to $212 (from $192), $110 (from $95), and $88 (from $78), respectively. El-Assal stated that the market is viewing the Q1 earnings report as "rearview mirror data" and is shifting attention to forward-looking growth drivers such as market predictions and tokenization. Despite the collective increase in target prices, the three stocks closed down approximately 2.78%, 4%, and 2% yesterday, reflecting the dual impact of macro sentiment suppression and geopolitical uncertainty.Circle Internet Group, Inc. (NYSE: $CRCL) closed yesterday (April 21) at about $97, with a decline of approximately 4.6% on the day, corresponding to a market capitalization of about $24 billion; the stock's 52-week low was $49.90 (on February 5), and it has rebounded approximately 95% from that low; Q1 2026 earnings report is expected to be released on May 11, with consensus revenue expectations for Q2 at about $718 million.

Jefferies, a Wall Street investment bank, pointed out that the approximately $293 million attack incident on Kelp DAO exposed critical infrastructure risks, which may prompt traditional financial institutions to reassess the pace of blockchain and tokenization advancement.Jefferies believes that the attackers triggered market sell-offs and liquidity strains by minting uncollateralized tokens and engaging in cross-platform lending. This incident is thought to be related to the Lazarus Group and also highlights the single point of failure issues in the verification mechanisms of cross-chain bridges. As institutions accelerate the tokenization of assets (such as funds, bonds, and deposits), the associated risks may cause some banks and asset management institutions to delay deployment and prioritize examining system security. Especially in scenarios that rely on cross-chain infrastructure, security vulnerabilities could lead to market fragmentation, undermining the practical utility of tokenized assets.Despite short-term confidence being shaken, Jefferies still emphasizes that the long-term trend remains unchanged. Under the backdrop of regulatory advancements and continuous improvements in infrastructure, applications such as stablecoins still have growth potential. However, the industry as a whole is still in the early stages of development and requires time to enhance system robustness.

ChainCatcher reported live that Li Baiwei, Partner at HashKey Tokenisation, John Cahill, Chief Operating Officer of Galaxy Digital Asia, Abdelhamid Bizid, Managing Director of BlackRock, and Min Lin, Managing Director and Head of Global Business Development at Ondo Finance, attended the HK Web3 Feastival roundtable to share insights on "From Wall Street to Blockchain: The Practical Logic and Future Landscape of Global RWA Issuance."The attendees generally agreed that the core value of RWA and asset tokenization is no longer just an innovative narrative at the conceptual level, but a realistic path for upgrading financial market infrastructure. John Cahill stated that blockchain is essentially a superior "underlying pipeline" for financial markets, and in the long run, the ultimate goal of financial markets will be "tokenization of everything"; what truly needs attention is not whether tokenization will happen, but whether market participants have already begun preparing for this endgame.Abdelhamid Bizid pointed out that from the perspective of traditional asset management institutions, the current tokenized products primarily serve clients who do not wish to move funds out of the on-chain ecosystem but want to achieve stable returns and compliant asset allocation tools. BlackRock has seen a clear demand for on-chain yield products and will continue to launch more new products. However, he also emphasized that the real bottleneck in the industry at this stage is not technology, but rather institutional adoption, demand validation, liquidity depth, regulatory clarity, and non-technical barriers such as costs and taxation.Min Lin, drawing from Ondo's practice, stated that the key to tokenized stocks is not just moving U.S. stocks onto the blockchain, but transforming stocks that are originally static in brokerage accounts into programmable financial instruments that can serve as collateral, margin, and lending assets in DeFi, further unlocking capital efficiency. He mentioned that the main demand currently observed by Ondo still comes from retail and crypto-native funds in regions like Asia, Southeast Asia, and Latin America, which find it difficult to directly access the U.S. stock market. This indicates that tokenized stocks at this stage are more like "global asset access tools" rather than mainstream trading venues for institutional funds.

The Japan Securities Clearing Corporation (JSCC), a clearing institution under the Japan Exchange Group, has partnered with Mizuho Bank, Nomura Securities, and Digital Asset to launch a proof-of-concept trial aimed at exploring the use of blockchain technology for collateral management of Japanese Government Bonds (JGBs).According to a joint statement released on Monday, the trial will integrate existing systems from multiple institutions through the Canton Network to test the on-chain transfer and management of JGBs. This initiative aims to assess the feasibility of achieving real-time collateral trading while ensuring compliance with relevant financial instruments and trading laws. The trial will also investigate cross-border use cases involving clearinghouses, institutional investors, and other market participants.JSCC stated that this trial is part of a broader initiative under the Financial Services Agency's "Payment Innovation Project." As overseas markets like the United States make progress in testing similar infrastructures, advancing JGBs collateral management has become an "urgent priority." Previously, the Depository Trust & Clearing Corporation (DTCC) in the U.S. launched a pilot to tokenize U.S. Treasury securities, and South Korea is also conducting related tests.

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 reports live that Lily Liu, President of the Solana Foundation, delivered a keynote speech at the 2026 Hong Kong Web3 Carnival. She pointed out from a macroeconomic perspective that global production, users, and resources are distributed globally, but capital formation is not; only 20 stock exchanges in 14 countries account for 94% of the global market value of approximately $145 trillion, with two-thirds concentrated in the United States. This means that about 180 countries have almost no access to capital markets, and their economies can only rely on debt rather than equity financing, failing to provide ownership pathways for their citizens.She proposed the vision of an "Internet Capital Market," where any asset from anywhere can raise capital from anyone globally, priced in dollars and settled on an open track. Stablecoins are the key infrastructure for this vision, enabling any country to participate in the global financial system, while Solana provides the underlying settlement and execution layers. She also contrasted "Universal Basic Ownership" (UBO) with the widely discussed "Universal Basic Income" (UBI) in the AI era, arguing that blockchain allows anyone with a mobile phone to hold a part of their country's economy, representing basic property rights in the digital age without resorting to placing everyone in a welfare system.
