Galaxy Research published an analysis stating that over the past three weeks, the Bitcoin network has seen approximately 40 inscriptions composed of random letters each day, which appear to be encrypted text but are not actually cryptographic information. The related address had previously written the U.S. Constitution into the Bitcoin network in May.The research found that after analyzing 562 texts, the frequency of the 26 English letters is almost evenly distributed, which is significantly different from the characteristics of normal English and substitution ciphers; metrics such as word length distribution and frequency of repeated words also indicate that these texts are likely generated by a random letter generator.Galaxy Research refers to the operator as the "Babel Scribe," believing it is more like testing a data publishing tool on the Bitcoin mainnet rather than attempting to convey hidden information. The structure of on-chain transactions, the continuous use of change addresses, and the regularity of publication times all exhibit characteristics of automated scripts. Related activities also include testing texts, random words in different languages, binary data, and the subsequent writing of the U.S. Declaration of Independence.It is estimated that the project has transferred approximately 3.33 million satoshis in total, of which about 24% was used to pay miner fees, while the remaining funds are still held in the related address. Researchers suggest that there is no need to interpret these garbled texts as hidden information.

The Office of the Comptroller of the Currency (OCC) has finalized the implementation rules for the GENIUS Act, applicable to licensed stablecoin issuers, foreign issuers under OCC jurisdiction, and certain custodial activities of regulated entities, covering reserve support, redemption, and risk management. Treasury Secretary Scott Bessent described the legislation as a "watershed moment for the U.S. financial industry," comparing it to the National Currency Act of 1863.The final rules do not include provisions for the Bank Secrecy Act, anti-money laundering, and OFAC sanctions, which will be addressed through subsequent rules coordinated with the Treasury Department. The GENIUS Act was signed into law in July 2025, and regulators failed to establish rules by the deadline of July 18, 2026; the Federal Reserve proposed two related rules in September 2026. Both the GENIUS Act and the OCC final rules are set to take effect on January 18, 2027, and the OCC has not yet announced the timeline for accepting issuer applications and exemption requests.

According to a report by The Block, Coinbase released a report titled "The Always-On Dollar" indicating that in the third quarter of 2026, the average hourly transfer amount of organic stablecoin transactions exceeded $400 million. Over the past 12 months, as of July 31, approximately 73% of filtered stablecoin transfer volume occurred outside of U.S. banking hours, highlighting the demand for 24/7 stablecoin payments.The report shows that the adjusted quarterly transfer volume of stablecoins has grown to four times its original amount since the beginning of 2023, reaching $891 billion in the third quarter of 2026. At the current growth rate, this figure is expected to reach $1.5 trillion by the end of 2027. The report also noted that using USDC to remit $200 through the Base network can save about 86% in fees compared to traditional payment channels. Furthermore, if 80% of global international transactions shift to stablecoin payment networks, the global annual GDP could increase by an additional $155 billion.Looking ahead, the report believes that stablecoins are likely to become an important payment infrastructure for the AI agent economy. McKinsey estimates that by 2030, between $3 trillion to $5 trillion in B2C commercial transactions will be facilitated by AI agents, with stablecoins supporting small transactions such as payment task fees between agents, purchasing API calls, and on-demand access to data and computing power.

They are cooperating with law enforcement agencies, cryptographic forensic experts, and investors to investigate, and have not yet disclosed the amount of losses or details of the attack.On-chain analyst Specter stated that they observed a certain wallet transferring approximately 35,700 ZEC (worth about $41 million at the time) from a privacy pool, which was then transferred to the Bitcoin and Ethereum networks via NEAR Intents and multiple addresses. Their tracking suggests that the related addresses are associated with the ILITY cross-chain bridge and claim that approximately 4.1 million ILY tokens flowed out of that bridge. Due to the privacy features of Zcash, it has not yet been confirmed whether this ZEC belongs to stolen funds or its exact relationship with the ILITY incident.

The Office of the Comptroller of the Currency (OCC) released a report on de-banking on Wednesday, pointing out that some banks had established "public and non-public policies" to restrict services to multiple industries, including oil and gas, tobacco, firearms, and digital assets. This report was issued based on an executive order signed by President Trump in August 2025, aimed at preventing what it calls "illegal de-banking" practices.The OCC stated that many institutions also imposed restrictions on digital asset businesses, involving issuers, exchanges, or management agencies, often citing financial crime considerations as justification. However, this 47-page report did not provide specific de-banking cases related to digital asset activities. The OCC noted that based on a review of nine large banks, it "could not fully quantify the overall scale of de-banking or alleged de-banking activities," with the agency's head, Jonathan Gould, primarily discussing claims of de-banking related to coal and firearms.Gould stated that these decisions were not based on financial risk; banks cited concerns about negative news, public protests, and the potential reputational consequences of supporting related industries. In November 2024, more than 30 executives from the technology and cryptocurrency industries claimed they were denied banking services, informally referring to it as "Operation Chokepoint 2." Trump's executive order in 2025 came after industry-related calls, following allegations that the Biden administration might influence financial institutions to cut off certain services to cryptocurrency companies.
