ME News, May 4 (UTC+8) — Federal Reserve Governor Kashkari said that an open mind is needed regarding the future of interest rate policy, and that the longer the war continues, the greater the inflationary pressure. In some cases, the Fed may need to raise interest rates, even if the war ends completely now, as it would still take several months for supply chains to recover. He is very concerned about the downside risks brought about by the war. The challenge facing the Fed is the uncertainty surrounding the path of inflation. He looks forward to cooperation following the confirmation of Warsh’s nomination and remains open-minded about some of the concerns expressed by Warsh. (Source: PANews)

AIMPACT published on May 4 that Vectorless RAG improves retrieval accuracy by removing the vector database. The PageIndex-style approach breaks with traditional retrieval logic by directly locating where the answer appears in a document instead of selecting the most similar text chunks. This enabled Mafin 2.5 to achieve 98.7% accuracy on FinanceBench through changes to the retrieval primitives, rather than a more powerful embedding model. Traditional vector RAG has limitations when handling complex nested queries and precise numerical queries, making this a difficult bottleneck to overcome.

Google Quantum AI’s latest white paper states that the number of physical qubits required to break core cryptocurrency systems has fallen to approximately 500,000, about 20 times lower than previous estimates, bringing the quantum threat into the medium-term quantifiable risk category. The attack focuses on elliptic-curve signatures and encompasses attacks on transactions in transit and assets at rest. Approximately 6.9 million bitcoins, or about 33% of the total supply, along with a large number of Ethereum accounts, have exposed public keys, creating an existing risk. Although the hardware gap remains, algorithmic optimization is ongoing. Q-Day is expected to occur between 2028 and 2035, with governance rather than technology constituting the bottleneck to migration.

The article states that Ethereum transactions can be divided into “actions” and “dependencies.” Dependencies can be processed in parallel, while the mempool and STARK proofs can reduce costs. Pure dependencies can be resolved at the mempool layer and replaced by STARKs. Scaling requires distinguishing between dynamic flexibility and static analysis, and more than 90% of transactions do not require dynamic flexibility. EIP-8141 is moving toward a universal minimal call list, while new state types, recursive STARK mempools, and keyed nonces are also under development.

Federal Reserve Governor Barr warned that stress in the private credit sector could trigger psychological contagion, thereby exacerbating the credit crunch, and emphasized that regulation of Wall Street should continue to be strengthened as risks rise. Although the direct links between banks and private credit are not currently “particularly concerning,” the overlap between insurance and private lending still warrants attention; if psychological contagion spreads through the private credit market, cracks could emerge in the corporate debt market, potentially triggering a broader credit contraction and financial stress.

AIMPACT News, May 4 (UTC+8) — Stanford University’s latest seminar explored the evolution of AI world models, focusing on the shift from traditional reconstruction methods to latent-space prediction. The seminar covered topics including an introduction to JEPA (Joint Embedding Predictive Architecture) and world models, causal JEPA, and LOWER. This information came from a retweet by the Stanford Natural Language Processing Group (Stanford NLP) on Twitter and was a seminar introduction that did not provide specific technical details or results.

ME News, May 4 (UTC+8) — "Fed whisperer" Nick Timiraos said that the Federal Reserve's autonomy, commonly referred to as its independence, stems from its institutional establishment by Congress. Congress created a committee composed of officials who serve long, staggered terms, enjoy protection from removal, and gave the institution full control over its budget (and buildings).

On May 4, SpaceX is about to launch a massive IPO, prompting large Wall Street funds to make sweeping portfolio adjustments. About a week ago, a private jet emblazoned with the SpaceX logo flew nearly 200 fund investors to Texas for a roadshow. Demand was extremely strong, with every seat filled. With the listing imminent, the market is buzzing with talk that investors are selling tech stocks to subscribe to SpaceX, potentially involving tens of billions of dollars.

According to a CoinDesk-commissioned survey of 1,000 U.S. voters, only 1% consider cryptocurrency the most important issue in the 2026 midterm elections, with the cost of living ranking first. Most voters hold negative views of crypto; 27% have invested in or used it, while another 27% may participate in the future. Some 47% believe Republicans are more crypto-friendly, compared with 14% who say the same of Democrats. However, when it comes to whom they trust to manage crypto-related matters, Democrats rank slightly higher than Republicans, while 40% say they trust neither party. Although crypto is not a core issue, around 40% of voters would be willing to vote for a candidate whose views on crypto align with their own.

ME News, May 3 (UTC+8) — SEC filings show that the New York Stock Exchange has submitted a rule change proposal to allow tokenized securities to be traded within the existing market system. The proposal is based on the DTC’s three-year pilot program and supports clearing and settlement via blockchain. Tokenized securities must have the same identifiers and shareholder rights as traditional securities and be traded on the same order book, subject to the same matching and regulatory rules. Settlement will remain T+1. The rule has taken effect, but regulators may suspend it and conduct further review within 60 days. (Source: MLion)

A U.S. court sentenced Meta-1 Coin operator Robert Dunlap to 23 years in prison for defrauding approximately 1,000 investors of more than $20 million. He claimed the token was backed by gold reserves and valuable artwork, promised high returns, and provided forged audit materials; the assets did not actually exist, the funds were used for luxury spending, and the token was never issued on-chain. The SEC filed a civil fraud case in 2020, but Dunlap was not criminally charged until 2024. The FBI said the case destroyed the wealth and trust of numerous victims.

Figure Technology Solutions CEO Cagney said the company is using blockchain to rebuild credit infrastructure by tightly integrating real-world assets, securitization, and DeFi, reducing intermediary costs and improving liquidity. Lending surpassed $1 billion in March, with approximately $2.9 billion in originations in Q1, or about $12 billion annualized. The company has launched the YLDS stablecoin and a credit vault on Solana, plans to expand into the Ethereum ecosystem, and is exploring stock tokenization and on-chain securities lending. The value of blockchain lies in rewriting the abstraction layer of finance.

A U.S. court sentenced Meta-1 Coin operator Robert Dunlap to 23 years in prison. The case involved more than $20 million, and approximately 1,000 investors were defrauded. Dunlap claimed the token was backed by gold reserves and famous paintings and promised high returns, providing falsified audit materials. In reality, the assets did not exist, the funds were used for luxury spending, and the token was never issued on-chain. The SEC filed a civil fraud lawsuit in 2020, but Dunlap was not criminally charged until 2024. The FBI said the case destroyed the wealth and trust of a large number of victims.
