According to The Washington Post, U.S. President Donald Trump failed to disclose his multi-million dollar stock trades involving companies like Microsoft and Amazon within the legal deadline, with delays lasting several months. He has been fined $200 as a result, according to the latest investment disclosure documents.The report noted that these trades involved several large technology and financial stocks, with disclosure information indicating that the scale of his asset operations reached "the tens of millions of dollars." The delay in related disclosures has raised concerns about whether he strictly adhered to federal financial disclosure regulations.According to the requirements of the U.S. Office of Government Ethics, federal officials must report significant financial transactions within the specified deadline, but there are issues with delays in actual enforcement and relatively light penalties.

According to Bloomberg, as crypto-native companies like Coinbase continue to lay off employees on a large scale and the industry as a whole is in a downturn, traditional financial institutions such as JPMorgan and BlackRock have recently bucked the trend by posting dozens of digital asset-related positions, becoming a major highlight in the current crypto job market.Analysts point out that having a background in Wall Street has become an important asset for crypto talent to maintain their competitive edge in employment during the industry's downturn.

According to Coinglass data, despite Bitcoin recently firmly standing above $80,000, the Coinbase Bitcoin premium index has started to turn negative. For most of April, the Coinbase Bitcoin premium index remained in positive territory.In addition, the IFP index, which reflects market participants' risk appetite and the direction of capital flows, has fallen below the 90-day moving average, indicating to some extent that Bitcoin is flowing back from derivatives exchanges to spot exchanges, suggesting a weakening of speculative interest and risk aversion, which typically corresponds to bearish/risk-averse sentiment.

According to Protos, Bitcoin Core developers recently disclosed a high-risk vulnerability numbered CVE-2024-52911, which affects versions 0.14.1 to 28.4, allowing miners to remotely crash other users' nodes and execute code by mining specially crafted blocks.The vulnerability was discovered and responsibly disclosed by developer Cory Fields in November 2024. The fix was merged in December of that year and released with version v29 in April 2025. The last vulnerable 28.x version series was discontinued on April 19, 2026.However, since upgrading Bitcoin full nodes is voluntary, it is estimated that about 43% of nodes are still running the vulnerable old version software, facing potential risks. Fortunately, the cost of implementing such an attack is extremely high—miners would need to allocate significant computational power to mine invalid blocks that do not yield block rewards—so it is likely that it has never been exploited in practice.

According to Jinshi reports, U.S. President Trump stated that despite small-scale conflicts, the stock market reached a historic high today.

According to official news, the Depository Trust & Clearing Corporation (DTCC) in the United States has announced the establishment of an industry working group to advance the tokenization process of the U.S. capital markets. Ondo has been selected for this working group and will collaborate with institutions from both traditional finance and decentralized finance, including BlackRock, Goldman Sachs, JPMorgan Chase, Franklin Templeton, Morgan Stanley, Bank of America, Citadel Securities, the New York Stock Exchange, Circle, Fireblocks, and Robinhood in the design process.DTCC holds assets exceeding $114 trillion, with an annual clearing total of $3.7 trillion. It is currently building a tokenization service aimed at bringing the core processes of the U.S. capital markets on-chain. DTCC President and CEO Frank La Salla stated, "We believe that tokenization will significantly change the way markets operate, bringing new levels of liquidity, transparency, and efficiency to investors."

The decentralized trading platform Aster announced that the sixth phase of the airdrop has been settled, with a total of 620,608.16 $ASTER distributed. Among them, 310,304.08 have been permanently destroyed, and another 310,304.08 have been transferred to the Aster Treasury contract.According to the arrangement, the 50% immediate claim window opened at 12:00 UTC on May 4 and will close at 12:00 on June 4.

According to FinanceFeeds, Alex Thorn, the research director of Galaxy Digital, stated that as advancements in quantum computing hardware accelerate, the Bitcoin community is shifting from decentralized debates to forming a preliminary consensus on quantum threats. The core direction is to gradually introduce post-quantum cryptography (PQC) through soft forks, achieving an upgrade of the address system and long-term security assurance.The report points out that the current Bitcoin signature mechanism, which uses the Elliptic Curve Digital Signature Algorithm, can theoretically be cracked by Shor's algorithm. Approximately 2 million BTC from early p2pkh addresses are at risk because their public keys have been exposed, facing the potential risk of "collecting first and decrypting later." The community tends to promote a "migration window" mechanism to guide users in transferring their assets to new quantum-resistant addresses, and after a multi-year grace period, to implement freezing or destruction of untransferred assets to prevent large-scale market impacts in extreme situations. Additionally, the consensus includes enhancing "cryptographic agility," which allows protocols to switch signature algorithms without interrupting the network.The current proposal leans towards a dual-signature mechanism that uses ECDSA and PQC (such as Dilithium) in parallel, ensuring security redundancy while facilitating a smooth transition. Analysts believe that this approach transforms the quantum threat from a "black swan event" into a manageable technological upgrade, helping to solidify Bitcoin's security foundation as a long-term store of value asset.

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.
