The cryptographic security vulnerability of the Indian certificate authority eMudhra affects the Ethereum clients Teku and Besu. Researchers found that the private keys of 8 intermediate certificate authorities under eMudhra could potentially be deduced due to insufficient randomness, allowing attackers to forge certificates and trick unpatched software into trusting malicious services.Teku has released version 26.1.3, and Besu has released version 26.1.2, both of which have removed trust in the relevant certificates from their Docker images. If an attacker performs a man-in-the-middle attack, they could trick some validators into sending block fee rewards to the attacker's address; the risk may be higher under specific configurations using external signers. The Teku team stated that the default configuration of the Ethereum mainnet Teku node is not affected, and no action is required, with no reports of the vulnerability being exploited so far.For operators running Teku or Besu directly on the host without using Docker, simply updating the client may not be sufficient; they also need to manually update Java and its trusted certificate list. Operators still using the no longer maintained Java 26 will need to migrate to Java 25.

Glassnode's latest report indicates that Bitcoin has fallen back below the range of $84,000 to $85,000, a range that has blocked price increases four times this year. The inflow of funds into the U.S. spot Bitcoin ETF has significantly cooled, with a net inflow of only about $67 million in the past two weeks; the major buy orders on Binance's spot order book have also shifted down to the range of $78,000 to $79,000, with a scale of about $42 million.Meanwhile, Bitcoin's one-month realized volatility has dropped to about 25%, returning to the levels seen in the summer of 2023; since August, the realized losses triggered by each round of decline have continued to narrow, indicating that selling pressure has eased.Glassnode believes that Bitcoin is currently in a range-bound state with weak demand and limited selling pressure, as the market is focusing on the Federal Reserve's interest rate decision. If the daily close re-establishes above $85,000, it may serve as an initial signal for further rebounds; if it falls below the average cost of active investors around $77,900, attention should be paid to the cost support for short-term holders near $75,800.

Bitget, in collaboration with Reality and Keyring, has released a research report exploring the synergy mechanisms of tokenized stocks, perpetual contracts, and decentralized lending, and evaluating the potential returns and risks of related strategies through simulation calculations. The report points out that the application of tokenized stocks is extending from traditional stock trading to more scenarios such as collateralized lending, asset management, and systematic investment strategies.The research is based on Reality's rToken, combined with stock perpetual contract hedging and on-chain lending mechanisms, to explore stock basis yield strategies. Historical simulation data shows that from December 15, 2025, to October 19, 2026, the annualized net return of the strategy index is approximately 7% and 4% for in-sample and out-of-sample, respectively, with a gross funding cost rate premium of about 11% to 14%. The report also notes that financing costs, transaction execution fees, market liquidity, and risk management are key factors affecting the actual returns of the strategy.It is reported that Bitget and Keyring plan to jointly develop a stock basis index and build an on-chain lending market based on Reality's rToken. Among them, Reality provides exposure to tokenized stock assets, while Keyring is responsible for developing the index methodology and constructing the related lending market. The index aims to capture funding rate and basis yield opportunities by combining rToken holdings with corresponding stock perpetual contract hedging positions, providing new strategic pathways for the application of tokenized stocks in on-chain financial scenarios.
