According to Crypto Briefing, Aave founder Stani Kulechov stated at the DAS London conference that DeFi lending protocols need to introduce a "circuit breaker" mechanism, as the consequences of oracle failures could take years to resolve.He pointed out that the over-reliance on immutable code systems lacks contingency plans. When oracle data deviates, the protocol may trigger liquidations based on incorrect prices, and the immutable nature can lead to irreparable failures. The circuit breaker mechanism draws from traditional markets' practice of halting trading during extreme conditions, allowing protocols to pause operations until the issue is identified.

The U.S. Central Command stated that the U.S. military continues round-the-clock operations to ensure the Strait of Hormuz remains open to commercial shipping and strictly enforces the maritime blockade against Iran.The U.S. collaborates with interagency partners to prevent the Iranian Islamic Revolutionary Guard Corps from using land routes and the Caspian Sea to transport advanced weapon systems, dual-use technologies, and illicit financial flows.

Web3 fitness protocol BRT.Fit founder and CEO Kevin Huang recently published an open letter to Yosemite founder Reed Jobs. In the letter, he proposed that in addition to developing treatment methods, establishing systematic behavior change mechanisms to help people develop long-term exercise habits is an important pathway to prevent certain cancers (such as breast cancer and colorectal cancer).Kevin Huang introduced that BRT.Fit integrates wearable devices such as Apple Watch and Oura Ring for real exercise verification, combining behavioral commitments, reward mechanisms, and community accountability to help users maintain exercise habits. He clearly stated in the letter that currently BRT.Fit has not proven to directly reduce cancer incidence, which requires rigorous long-term scientific research, but the project is committed to bridging the gap between scientific knowledge and human behavior transformation.

According to the official account of the Linyi City Media Center, the Linyi authorities have issued a risk warning, exposing two major illegal financial scams: "Global Securities Exchange" and "Savings Project" APP.Among them, the "Global Securities Exchange" project promotes high returns, enticing the public to invest in and purchase virtual currencies. Participants are advised to withdraw as soon as possible to prevent losses. The notice issued by the People's Bank of China and other departments regarding further prevention and handling of risks related to virtual currencies clearly states that virtual currencies do not have the same legal status as legal tender.

According to The Block, the Singapore Police Force stated that they successfully prevented $17.4 million in fraud losses in a joint operation with cryptocurrency exchanges.The police utilized blockchain analysis and customer data from platforms such as Coinbase and OKX to identify over 383 victims. Intelligence shared with the FBI, New South Wales Police Force, and the Canadian Anti-Fraud Centre also helped identify 32 foreign victims.

According to Jinshi reports, the South Korean Finance Minister stated that proactive measures will be taken to avoid escalating market anxiety.The South Korean Finance Minister also mentioned that regulations on borrowing and investment will be relaxed to alleviate market volatility; if volatility further intensifies, additional stabilization measures will be implemented.

Anthropic has open-sourced FlashProve, bringing the commonly used zkSNARK (zero-knowledge proof) technology from the cryptocurrency field into AI model inference.This technology was originally designed to prove the validity of blockchain transactions without disclosing transaction details. Anthropic aims to use it to solve another problem: when users pay a high price for an AI model's API, how can they know if the service provider has secretly switched to a cheaper model?FlashProve allows service providers to first generate encrypted fingerprints for the model weights and then provide mathematical proof for the inference results. Users do not need to obtain the model weights or rerun the model; they can check whether the specified output comes from the previously committed set of weights. Claude was also involved in the development and optimization of this system.Anthropic has already completed experiments on Meta's 400 billion parameter model Llama 4 Maverick. For every 1024 tokens of context processed, the generated proof is about 19 MB, and verification on a regular CPU takes about 17 seconds.However, currently, each proof can only verify one output token and cannot validate an entire response. The GPU computation time required to generate the proof is also about 70 to 95 times that of regular inference. Whether it can be used to identify API service providers that secretly switch models in the future will depend on when the cost of proof generation can be reduced.

Binance founder Zhao Changpeng stated in an interview, "After the attack incident, Binance quickly stepped up to clarify that user funds were not affected and user assets are safe. Although this is just a very simple statement, it effectively prevented panic from spreading further and avoided a chain reaction.Everyone understands that this incident will not have further spillover effects. Unlike previous cases where some platforms or lending protocols went bankrupt, ultimately causing users to bear losses, this time users will not be forced to bear related losses. This is fundamentally different from some past events, which often triggered second and third rounds of chain reactions. I believe that, first, this statement calmed everyone down. Secondly, Binance's ability to make such a commitment based on its own credibility also made users willing to believe this statement. After all, many fund flows and transaction records on the blockchain are public and transparent.However, this situation is different; users understand that Binance has sufficient financial strength to bear related losses. Binance has the SAFU (Secure Asset Fund for Users), a futures insurance fund, as well as very strong capital strength and a solid balance sheet. It is this ability to respond quickly, take responsibility proactively, and ensure that all users are protected and all losses are compensated that has gradually restored calm to the market.One interesting point: on the day of the incident, the decline in the cryptocurrency market was actually smaller than that of the tech stock market, a situation that is almost unprecedented. Typically, when the stock market declines, the crypto market often experiences a larger drop, as investors looking to hold cash tend to sell off crypto assets. But this time, even with such a severe hacking attack on the crypto industry, the market decline was smaller. I believe this indicates that investors overall remained quite calm, and it reflects the solid trust in the platform that has been gradually built over the years. I feel very proud of this."

According to South Korean media "The Pioneer Economy," the Financial Services Commission of South Korea urgently convened representatives from trading platforms such as Upbit, Bithumb, and Coinone on the morning of November 2 to hold a security inspection meeting. The focus was on checking each platform's preparedness for large-scale hacker attacks and the user asset protection systems.This meeting was scheduled ahead of a security inspection meeting for the entire financial industry on November 5, aimed at understanding the response measures of the South Korean cryptocurrency industry in light of the recent large-scale asset theft incident involving Binance. The meeting will also discuss proposals to increase the proportion of user assets stored in cold wallets.According to South Korea's current "Virtual Asset User Protection Act," trading platforms must store at least 80% of users' virtual assets in cold wallets that are isolated from the internet. Reports indicate that Upbit's cold wallet storage ratio exceeds 99%, Bithumb is around 94%, Coinone is about 85%, while Digital X and Gopax are just above 80%.

The commander of the United States Central Command stated that strong blockade measures have successfully prevented Iran from exporting any oil.

The founder of the cryptocurrency trading platform Gate, Han Lin, published an article sharing thoughts on fund security, proposing the Vault solution. The core principle is to prevent any party from having the ability to unilaterally access the funds. The private key is split into three shards through MPC, held respectively by the user’s device, Gate, and a disaster recovery party. The complete private key will not appear in any single location.Han Lin stated that since 2026, there have been over 600 security incidents, resulting in losses exceeding 8 billion dollars. In September alone, the losses amounted to 768 million dollars, and October is not yet over, with monthly losses already exceeding 6 billion dollars. More than 60% of the losses in the first half of the year were due to private key breaches and phishing, while code vulnerabilities accounted for just over 10%. In October, a hardware implant attack targeting distribution channels caused users to lose nearly 100 million dollars.The solution sets a 48-hour delay for Vault withdrawals, during which users can freeze their accounts at any time. If a user’s device is lost or the backup password is forgotten, Gate and a third party can assist in recovery after the user completes identity verification. If Gate services are unavailable, users can use device shards combined with third-party shards to recover assets through open-source tools. Han Lin expressed that the platform is willing to open up this architectural idea and the real user scenarios encountered for discussion among peers.

Binance stated that its security team successfully identified and prevented multiple cyberattacks related to North Korea in the past week, without causing damage to the company's systems or loss of assets. Binance pointed out that North Korean hacker groups have recently been continuously conducting social engineering attack activities named Contagious Interview.This activity uses scenarios such as fake job interviews, code testing, and software installation to lure targets into running malicious programs. Binance reminds users to avoid installing unauthorized software or executing code from unknown sources and stated that it will continue to strengthen security monitoring, threat identification, and internal security management.

According to CoinDesk, Ethereum developers have fixed a vulnerability in the Glamsterdam upgrade that could allow operators to withdraw ETH intended for new validators from the staking service. The fix changed the handling rules for validator deposits and was merged on Monday, after developers had rejected the modification a week earlier.Researcher avsetsin discovered that if an operator first registers as a builder with a specific public key, and the staking service subsequently deposits ETH using the same key to activate the validator, the draft rules would credit both deposits to the builder. Avsetsin stated that this is a conditional code discovery and not a confirmed real-time exploit; existing checks can prevent the attack, and there are currently no reports of losses. The new rules treat deposits as sorted by withdrawal receipts, ensuring that validator deposits still belong to the validators.Glamsterdam has been running on the Sepolia testnet, but the launch on the Hoodi testnet has been delayed, with a new date to be determined before the mainnet launch.

The venture capital firm a16z published comments from co-founder Marc Andreessen on X regarding open-source AI. Marc Andreessen: If the only way for children to learn AI is to work at one or two companies, it would be hard for parents to accept.He also stated that in an open-source world, every child can understand how the relevant technology works. Without open-source, AI will inevitably be concentrated in one or two companies, or even directly in the hands of the government.Marc Andreessen also used the analogy of "government sushi," asking people to imagine "government AI," and stated that open-source is a safeguard to ensure this scenario does not become a reality in the future.

According to Cointelegraph, Coinbase's European policy director Katie Harries wrote that the proposed cryptocurrency asset regulatory rules by the UK's Financial Conduct Authority (FCA) may require regulated platforms to execute customer orders only on trading venues authorized by the FCA, thereby restricting users' access to decentralized finance (DeFi) protocols through compliant platforms.Since decentralized protocols typically do not have entities that can apply for regulatory authorization, the relevant rules may lead to regulated platforms being unable to provide DeFi access services, effectively creating a ban. The related cryptocurrency regulatory system is expected to be implemented starting October 25, 2027.

The Zakura team, which operates the Zcash network, released a technical article stating that they plan to allocate a unique viewing key for each ZEC exchange completed through NEAR Intents, in order to block future quantum computers from exploiting public refund addresses to piece together user payment histories. NEAR Intents supports cross-chain token exchanges, and when users exchange the privacy coin ZEC for USDC, the service will publish a Zcash address for the user on the NEAR public blockchain, which will be used to return any unused ZEC.The Zcash address contains a public key generated by the wallet's viewing key, which cannot be reverse-engineered by ordinary computers, but large quantum computers running Shor's algorithm could theoretically deduce the key from the address. Zcash wallets can generate multiple seemingly unrelated addresses, but they typically share the same viewing key. Once an attacker cracks it, they can associate all payments received by the account and read the amounts and notes. Zakura's solution allocates a unique viewing key for each exchange, while the spending key remains in the user's main account. Even if the future refund address is compromised, the attacker would only be able to see payments related to that specific exchange.This design also addresses a practical issue: wallets conducting hundreds of exchanges would generate hundreds of keys, requiring each key to scan the entire Zcash chain during backup recovery. Zakura's solution is a privately queryable database that uses private information retrieval technology, so when the wallet inquires about the refund destination, the database will not know the address being queried. Zakura claims that wallets built on its open-source library (including Vizor) will be able to add this feature in the coming weeks, and hardware wallets will follow after firmware support, ahead of the January quantum-resistant payment target set by Zcash developers this month.

Coinbase co-founder and CEO Brian Armstrong stated: The company has fine-tuned the open-source weight model Qwen3.5-9B using internal proprietary data, which performs better than cutting-edge models in the specific task of fraud prevention, while also being more cost-effective and faster.Armstrong mentioned: Cutting-edge models are excellent general models, but companies will increasingly use specialized models for narrower tasks, which can operate independently or collaborate with teams. He believes this pattern will become more prevalent within the company.He also noted that Coinbase is making it easier for employees to fine-tune models internally and providing relevant skills in internal tools, with example instructions for fine-tuning Qwen for payment risk audits. He anticipates that some backend services may be completely replaced by this new architecture.

The Chairman of the U.S. Commodity Futures Trading Commission (CFTC), Mike Selig, stated that the proposed regulatory framework for crypto assets by the CFTC will establish a federal-level regulatory system to protect exchange customers from risks such as fraud, market manipulation, and theft of customer funds, preventing a repeat of the FTX collapse.Mike Selig pointed out that the CFTC is working to introduce a market-based regulatory mechanism for crypto exchanges; he stated that critics opposing relevant measures and supporting the status quo may objectively benefit fraudsters, manipulators, and those misappropriating customer funds, and warned that the lack of appropriate regulation could leave opportunities for the next figure similar to Sam Bankman-Fried.
