U.S. Treasury Secretary Becerra stated that the "GENIUS Act" is a watershed moment in the U.S. financial sector, further solidifying the United States' position as a global cryptocurrency hub.He pointed out that just as President Lincoln's National Currency Act of 1863 established a national framework for banks to issue currency, the "GENIUS Act" establishes a federal framework for payment stablecoins in the digital age.Becerra noted that the Office of the Comptroller of the Currency's (OCC) final rule advances the implementation of this landmark legislation, providing a clear and pragmatic foundation for private sector innovation, competition, and the United States' leadership in the digital asset space.

According to Cointelegraph, blockchain security company CertiK stated that although Google, Apple, and Microsoft have blocked 8 affected certificates issued by the Indian digital certificate authority eMudhra, cryptocurrency trading bots and exchange applications may still be exposed to related vulnerability risks, and browser fixes may not cover software that uses independent security systems.Peiyu Wang, Senior Director of Digital Asset Security at CertiK, pointed out that attackers could exploit the compromised certificates to impersonate exchanges, wallet interfaces, and APIs, replace deposit addresses, or induce users to approve malicious transactions. However, such attacks also require intercepting or redirecting network traffic, and the compromised certificate authority keys alone cannot expose wallet private keys. Cryptocurrency service operators should update software and certificate trust stores and ensure that applications reject affected certificates.

ARK Invest's Q3 2026 DeFi report shows that stock tokenization has become the main driving force behind the rebound in on-chain trading activity for the quarter. The trading volume of tokenized stock spot DEX reached approximately $50 billion, about 9 times that of the previous quarter, with its share of total spot DEX trading volume rising from about 1% to around 9%. Overall, DEX spot trading volume increased by approximately 13% quarter-over-quarter to $571 billion, marking the first growth in nearly four quarters.Robinhood Chain achieved approximately $65 billion in DEX trading volume and $51 million in network revenue in its first quarter, with network revenue nearing the level of BNB Chain during the same period. However, ARK expects that recent adjustments to the Gas mechanism will cause the chain's revenue to decline from current levels. The total supply of stablecoins decreased by about 3% quarter-over-quarter to $309 billion, but adjusted trading volume increased by approximately 16% quarter-over-quarter to $781 billion, with the number of monthly active addresses growing by about 39% to 73 million.In the perpetual contract DEX, there is a divergence between open positions and trading volume: the value of open contracts increased by about 76% quarter-over-quarter to $24 billion, while quarterly trading volume decreased by about 16% to $1.4 trillion. Among them, Hyperliquid's open contract value is about $13 billion, accounting for approximately 53%. ARK believes this indicates fewer but larger positions held for longer durations.

According to Bloomberg, financial executives have differing opinions on whether AI has become a bubble. Ken Griffin previously warned that AI investors are almost certainly in a bubble and should prepare for setbacks, stating that significant economic transformations are often accompanied by bubbles. Recently, the market has been concerned that the time it takes for the massive upfront capital expenditures in AI to translate into profits and productivity gains may be longer than expected. Deutsche Bank CEO Christian Sewing stated that there is no reason to worry about a sharp reversal in asset prices in the short term; individual companies may face setbacks, but he does not believe the market is in a bursting bubble.Sewing distinguished between a bubble and ongoing volatility, mentioning geopolitical tensions. He stated that if the regulatory framework is appropriate, the industrial application of AI will become a century opportunity for Germany. BlackRock CEO Larry Fink advocated for accelerating the construction of AI data centers, warning that delays could threaten economic growth and exacerbate inflation due to high computing costs. He previously mentioned that AI faces a supply shortage, with demand growth exceeding expectations, and stated that the faster more data centers are built and more computing power is available, the quicker costs can be reduced.Federated Hermes Chief Investment Officer for Global Equities Steve Chiavarone said that investors worried about an AI bubble may be correct in their judgment, but it is several years too early; infrastructure still has several years of growth potential, after which the risk of overbuilding will become more pressing. The market is still differentiating which companies can secure funding and at what interest rates, which is contrary to the bubble period.Compared to the AI bubble, both Fink and Sewing view the fiscal deficit as a more pressing concern, especially as the AI industry competes with the government for investment funds. The U.S. fiscal deficit is nearing $2 trillion, and U.S. Treasury yields have risen to decades-high levels.Fink stated that the current level of capital competition is the highest he has seen in his career. Regarding the rising risk of French government bonds, Sewing said it cannot yet be called a debt crisis, but it serves as a warning for public finances, emphasizing the importance of budget discipline.

The French Ministry of Finance, the Financial Markets Authority (AMF), the French Central Bank, and the Prudential Supervision and Resolution Authority (ACPR) jointly proposed amendments to the EU's Markets in Crypto-Assets Regulation (MiCA), requiring cryptocurrency platforms to take responsibility for customer losses when they actively provide access to DeFi protocols without reviewing the protocols or ignoring known security risks.The French side proposed that platforms review relevant protocols before providing DeFi access and continuously monitor for vulnerabilities and suspicious activities, while also supporting the certification of protocols and smart contracts. These requirements will apply comprehensively to significant Crypto Asset Service Providers (CASP), with smaller platforms subject to proportionately adjusted obligations. France also proposed transferring the regulatory authority of significant CASPs from national regulators to the European Securities and Markets Authority (ESMA) and lowering the current EU daily active user threshold of 15 million. Additionally, France suggested re-examining the category of Asset-Referenced Tokens (ART) and adjusting the Electronic Money Token (EMT) framework to cover multi-currency stablecoins.

The core feature of the NU7 upgrade is to reduce the time interval between Zcash blocks from 75 seconds to 25 seconds. This change means that the time required to wait for three transaction confirmations will be shortened from nearly four minutes to about 75 seconds. This upgrade has been running on Zcash's test network and is awaiting final integration into the node software.In addition to improving speed, NU7 will also bring two important adjustments: first, 60% of the fees collected from each block will be removed from circulation, and these tokens will begin to be returned to miners around February 2031. Second, Zcash's original Sprout privacy system will be completely shut down, so all funds still held in that system must be transferred out before the upgrade is activated; otherwise, they will become unusable.

Ripple's brokerage business Ripple Prime (formerly Hidden Road) announced that institutional clients can now trade swap contracts linked to over 100 stocks, commodities, and foreign exchange markets around the clock, using the USD stablecoin RLUSD issued by Ripple as collateral. These swap contracts track perpetual futures listed on the cryptocurrency derivatives exchange Hyperliquid by Trade.xyz, which have no expiration date and can be traded 24/7, allowing funds to build positions in assets like gold while traditional markets are closed. Ripple announced on October 15 that trading company Virtu is already using this service.HSBC's head of digital asset research, Daragh Maher, stated in a report sent to clients on Monday that this launch is "evolution rather than revolution." He wrote that it is a rapidly growing market but still far smaller than the traditional financial markets it tracks, and the product's appeal will be stronger only when the market has sufficient depth, allowing investors to express views and adjust risks while traditional markets are closed. HSBC expects early activity to focus on market makers, proprietary traders, and hedge funds seeking basis trading, rather than institutions looking for strategic hedging.The risks of weekend trading have already become apparent. Last Saturday, approximately $52 million in leveraged chip stock positions were forcibly liquidated within 10 minutes, with the sell-off spreading from Binance to Hyperliquid, while the underlying stocks were not trading, and the contracts lacked new stock market prices for reference. HSBC stated that Ripple's success depends on whether the service is cheaper, simpler, and can better utilize client collateral compared to existing brokers. The new swap business is offered under Ripple Prime's British Virgin Islands license, with plans to expand to more jurisdictions in the future.

Solana's largest network upgrade since 2020, Alpenglow, officially launched on Wednesday. This upgrade moves validator voting from on-chain to off-chain, packaging votes into certificates that can lock transactions within one to two rounds, aiming to reduce the final confirmation time for transactions from about 6 seconds to approximately 150 milliseconds, speeding it up by about 40 times. If this goal is achieved on the mainnet, Solana's transaction settlement speed will be faster than the blink of an eye, bringing it closer to the trading and payment experience of centralized exchanges.Currently, a 6-second confirmation time means that prices may change before the transaction is locked, causing exchanges and payment applications to wait before considering deposits as complete. In comparison, Ethereum takes about 13 minutes to achieve full final confirmation. At the same time, validator costs are expected to decrease by about 60%: currently, validators spend about 2 SOL daily on voting fees, which doubled after Solana recently reduced block time to about 200 milliseconds; Alpenglow eliminates voting fees, replacing them with a fixed validator entry fee of 0.8 SOL per epoch (approximately 24 hours).The upgrade launch process was not smooth. The testnet has been cleared and restarted from scratch six times since its launch in early May, with one migration failing across the entire network and having to be rolled back. According to an article published by Galaxy Digital, one of about 100 validator operators on the testnet, a subsequent migration was successfully completed, clearing the way for Wednesday's launch. Since these events occurred on a network built specifically for testing, there was no risk to real funds. The upgrade was scheduled to switch at the start of epoch 1064 on Wednesday, with actual changes occurring at slot 459,653,000 after a transition of 5,000 slots.
