The U.S. Department of the Treasury has imposed financial sanctions on eight Canadian currency service companies, stating that these companies have business dealings with sanctioned Iranian entities. The Treasury Department's statement indicated that the aforementioned companies facilitate the exchange of Iranian rials and other currencies and digital assets, enabling them to conduct international transactions. The related sanctions will isolate these companies from the U.S. dollar financial system.The U.S. Treasury stated that these businesses handle transactions for sanctioned Iranian digital asset exchanges and digital asset addresses associated with the Iranian Islamic Revolutionary Guard Corps. Treasury Secretary Scott Bessent stated that Canada cannot become a haven for illegal financial practitioners providing sanction evasion services to the Iranian regime and its proxies, and the Treasury will pursue and cut off financial channels for the Iranian regime globally. This action was coordinated with Canada's financial intelligence agency FINTRAC, as some sanctioned entities have attempted to evade scrutiny by changing their names and addresses.On the same day, the U.S. "Rewards for Justice" program offered a reward of up to $20 million and possible relocation arrangements for information regarding Iran's nuclear program, including its facilities, equipment, and personnel. The statement noted that Iran has not complied with the International Atomic Energy Agency's safeguards oversight, resulting in the agency losing "knowledge continuity" regarding Iran's production of enriched uranium and centrifuge components.

OpenAI Chief Financial Officer Sarah Friar stated in an interview with CNBC on Friday that the company will not change its AI infrastructure investment plans due to the results of the U.S. midterm elections. It will continue to collaborate with major hyperscale cloud service providers and meet AI customer demands through financing. She believes that the election results will not significantly change the company's business, but with increased attention on data centers, OpenAI will continue to strengthen communication and build trust with local communities.In this midterm election, out of 41 local data center-related votes in 10 states, only one did not support measures to limit construction or oppose support for development. Voters are mainly concerned that data centers will drive up electricity costs, harm the environment, and impact employment. Friar stated that OpenAI secretly submitted its listing application to the U.S. Securities and Exchange Commission in June and is considering going public in 2027, while negotiating a new round of financing with a pre-investment valuation of $1.25 trillion. She emphasized that the demand for AI is real and continues to grow.

According to Bloomberg, Wall Street's reaction to the U.S. midterm elections shifted from positive to negative in about 24 hours. The sell-off on Thursday spread from retail investors to hedge funds, long-only asset management firms, and quantitative strategies, causing a loss of approximately $3.7 trillion in market value for U.S. stocks in a single day, with the Nasdaq 100 index recording its largest drop since March 2020. Initially, the stock market rose after the elections due to the reduction of event risk and a decline in oil prices, but investors later reassessed the risks of Democratic scrutiny on data center expansion.In the first half hour after the market opened on Thursday, retail investors were the first to sell for profit, followed by hedge funds and long-only firms. Data from Vanda Research shows that the net selling scale of retail investors on that day was second only to two days during the pandemic shock in March 2020. Its strategist Viraj Patel pointed out that while retail and systematic investors were actively selling, institutional buyers chose to step back. The decline subsequently triggered mechanical selling, with Nomura strategist Charlie McElligott estimating that based on the negative gamma exposure during Thursday's trading, for every 1% drop in the market, options market makers would generate an additional selling pressure of about $7 billion.Volatility control funds estimated that they needed to reduce their holdings by about $61 billion in stocks based on market changes at the time, with about $25 billion in sales still being executed on Wednesday. The rebalancing of leveraged ETFs is expected to bring about an additional $47 billion in stock sales. Vanda estimated that commodity trading advisors sold about $13 billion in S&P 500 and Nasdaq futures. Goldman Sachs' prime brokerage trading desk estimated that fundamental long-short funds lost about 1.3% on Thursday, while technology-themed funds fell over 4%. The basket of stocks in storage, optical networks, data centers, and AI semiconductors dropped by 12% to 15% that day, and the VIX index rose from 16.6 points at the opening to nearly 28 points at the close.

According to multiple security researchers and KOLs, the iOS exploit toolkit DarkSword poses a serious threat to cryptocurrency users. This exploit takes advantage of an underlying flaw in iOS 18, allowing users to simply open infected websites through Safari, enabling malicious code to run in the background of the phone without the need to connect a wallet or perform any signature authorization. Attackers can use this to steal passwords, photos, files, as well as private keys and mnemonic phrases from cryptocurrency wallets.At least 18 malicious websites have been identified, resulting in victims losing up to 5.57 million dollars, involving more than 20 wallets. Zhao Changpeng commented on this, urging users to update their iOS systems, especially if they haven't updated for a while. He stated that no wallet software can update your operating system for you, and self-custody means self-responsibility.

Bull Bitcoin, a Bitcoin-exclusive exchange, announced a deep integration with Payjoin, claiming to be the world's first Bitcoin exchange to offer Payjoin as a deposit and withdrawal option, introducing two new concepts: "default Payjoin" and "Payjoin transaction." Founded in 2013 by Francis Pouliot in Canada, Bull Bitcoin is the longest-operating Bitcoin-exclusive exchange globally, with its non-custodial platform allowing users in Canada, Europe, and Latin America to buy Bitcoin directly into their wallets or sell Bitcoin to bank accounts. The company also developed the free and open-source Bitcoin self-custody wallet BULL Wallet, which has been self-funded since its inception.Payjoin is an on-chain privacy protocol for Bitcoin that breaks the fundamental assumptions made by on-chain analysis companies about user behavior, such as the assumption that one of the unspent transaction outputs (UTXO) generated by a transaction is change returned to the sender. The protocol adds a layer of off-chain coordination that obscures user intent by making the amounts sent and returned ambiguous, thus protecting on-chain privacy without requiring a hard or soft fork of the Bitcoin consensus. When BULL Wallet users buy and sell Bitcoin on-chain through the built-in exchange, transactions will default to using Payjoin, helping buyers passively aggregate UTXOs in their wallets, reducing future Bitcoin miner fees while shrinking the Bitcoin UTXO set size and alleviating fee pressure for all users.Payjoin transactions are used to protect users from malicious actors attempting to glean their financial habits through on-chain analysis. Since Bitcoin transaction amounts are public, outsiders may infer personal salaries or investment strategies, and as a non-custodial exchange, Bull Bitcoin leaves an on-chain trace for every transaction. In December 2024, BULL Wallet became the world's first wallet to integrate the Payjoin V2 protocol, a project advanced in collaboration with Dan Gould and the Payjoin Dev Kit team, with all related wallet and exchange software being completely free and open-source. Users only need to download BULL Wallet, create a Bull Bitcoin exchange account, and log in through the BULL mobile app, with the rest of the process being automated.

The Financial Action Task Force (FATF) released a new report titled "Combating the Full Chain of Illegal Fund Flows Related to Scam Hubs," calling on countries to take globally coordinated action to dismantle scam parks and their criminal networks.The report points out that criminals use channels such as cash, virtual assets, and instant payment platforms to launder money, and leverage AI, deep forgery, and automation technologies to scale up their operations. Among these, virtual assets have become the core channel for money laundering; in some cases, scam hubs even have dedicated over-the-counter trading counters for handling virtual asset exchanges and domestic fund transfers.In one case, blockchain analysis revealed that the total amount of funds sent in by victims exceeded $100 million, ultimately flowing into a cluster of virtual asset wallets associated with a particular scam hub.To address this, the FATF proposed six core principles, including focusing on a broader criminal ecosystem, end-to-end disruption of illegal fund flows, enhancing interdepartmental information sharing and cooperation, rapid cross-border action (especially within 24-72 hours after an incident), a victim-centered approach, and continuously adapting to changes in criminal methods.

According to Bloomberg, the Binance hacking incident is prompting the cryptocurrency industry to re-examine its long-held decentralized philosophy, as well as the transaction review, settlement delays, and fund intervention mechanisms in the traditional financial system.As the cryptocurrency industry seeks to enter the mainstream financial market in the United States, some institutional investors are beginning to reconsider Wall Street's financial risk control mechanisms. In traditional finance, banks, payment networks, and clearing institutions can review suspicious transactions during the fund transfer process and can suspend fund flows under certain circumstances.Third Eye CEO Tian Zeng stated that he hopes the settlement time can be shortened from the traditional financial T+1 day to T+1 hour, by appropriately extending the settlement time and increasing review steps, thereby reducing hackers' ability to quickly transfer funds.FalconX Co-Head of Markets Joshua Lim pointed out that as more institutions enter the cryptocurrency market, the client structure is changing, and some institutions are no longer willing to fully accept the risks associated with irreversible transactions. As the cryptocurrency industry further integrates with traditional finance, how to balance transaction efficiency, decentralization, and fund security will become a problem that the industry must face.
