Ethereum developer Marchhill submitted the draft EIP-8437, proposing to propagate proof wrapper data through the eth/73 protocol and introducing an optional mode that allows transactions to submit raw signatures to the aggregator without pre-generating STARK proofs.This proposal supports the direct propagation of certified packages with transactions and performs independent checks of specified programs in resource-constrained sandboxes to verify witness data. The new program does not require the development of native adapters for each signature scheme separately. Additionally, the proposal plans to limit the batch queue size, clean up expired transactions, and recheck records before formally generating proofs to support failure retries.Currently, the proposal is still in the Draft stage and has not yet been merged. The developer pointed out that VM and key binding consistency verification, cryptographic verification, and performance testing are still incomplete, and benchmarking has not yet been conducted.

Scroll announced that it received a vulnerability bounty report on November 3, indicating that there was a vulnerability in the bundle proof validator deployed on the Ethereum mainnet, and it registered a fixed validator for batch version 10 on November 10. Scroll stated that it has confirmed that the vulnerability was not exploited on the mainnet.According to the report, the vulnerability could allow old valid proofs to be accepted for new public inputs, thereby allowing the final confirmation of any state root and withdrawal root. Exploiting this vulnerability requires having a permissioned prover role or enabling the forced batch mode after 7 days without final confirmation.Scroll stated that the forced mode was never enabled, and all 748 final confirmations during the period of the vulnerability used normal proofs, with previous versions of the validator unaffected.

The public chain Sei announced that the SIP-6 proposal has been approved, and the development team Sei Labs will initiate the Autobahn consensus upgrade. This is a core part of the Sei Giga upgrade, which will change the mechanism of a single validator proposing blocks to multiple validators proposing transaction batches in parallel.This adjustment aims to enhance the network's ability to process order placements, order cancellations, and price updates. Sei's previously announced performance targets are to handle 200,000 transactions per second and achieve final confirmation in about 250 milliseconds. The announcement did not disclose the mainnet activation time.

Agave v4.5 is tentatively scheduled for widespread adoption on the mainnet on December 7, and the mainnet functionality activation is planned to begin on December 14.

On November 9, 2026, Google released an emergency stable channel update for the desktop Chrome browser, fixing nine security vulnerabilities, including a zero-day vulnerability that was already being exploited in the wild. This update raises the Chrome version on Windows and Mac platforms to 157.8103.5/.51, and to 157.8103.5 on the Linux platform, and will be gradually rolled out over the next few days to weeks. The core focus of this update is the high-risk vulnerability numbered CVE-2026-125350, which is a use-after-free issue in an XML component. Google explicitly stated in the announcement that "CVE-2026-125350 is known to be exploited in the wild," but did not disclose specific attack methods, the scale of victims, or attribution of the attack activities.The vulnerability was reported by an anonymous researcher on November 6, 2026, just three days before Google released the fix. Among the nine fixes, seven are classified as "high risk" and two as "medium risk." In addition to CVE-2026-125350, another high-risk vulnerability, CVE-2026-125346, also pertains to a use-after-free issue in an XML component, reported by Arni Hardarson of Neonix Security on October 12, 2026, but Google only marked CVE-2026-125350 as an actively exploited vulnerability. The other high-risk vulnerabilities include uninitialized resources in WebGL, improper FileSystem authorization, synthesizer buffer overflow, GPU out-of-bounds write, and V8 type confusion, most of which were discovered by Google's internal security team.Google also confirmed that the Android version of Chrome (157.8103.5) released on the same day includes the same security fixes as the desktop version, with no exceptions noted. Users on the Extended Stable channel should install the update released separately on November 9, with Windows and Mac versions being 156.8078.96, which also lists CVE-2026-125350 as a high-risk fix. The Hong Kong Government Computer Security Incident Coordination Centre (GovCERT.HK) issued a security alert on the same day, defining affected systems as versions prior to Chrome 157.8103.5, and pointed out that successful exploitation of the related vulnerabilities could lead to remote code execution, denial of service, tampering, or bypassing security restrictions. The Hong Kong Computer Security Incident Coordination Centre (HKCERT) rated the risk level of this update as "extremely high risk." Google explained in the announcement that access to vulnerability details and links may remain restricted until most users complete the update. The company recommends that users manually check and trigger the update via "Settings → About Chrome," and restart the browser after completing the update for the patch to take effect. For users still running versions prior to Chrome 157.8103.5, the current priority action is to confirm the version number and restart immediately to complete the upgrade.

Zcash community member ValarDragon posted on the official community forum, proposing a series of plans to be included in the NU8 network upgrade, and suggested setting the upgrade target for the end of January 2027. The main content includes the launch of the Tachyon shielded pool, expanding transaction formats, increasing the maximum block size from 2MB to 8MB, and adding support for post-quantum cryptography transparent transaction opcodes.Other proposals also include: adjusting the NSM redistribution date to be closer to the time of Zcash's seventh halving; determining a date at the protocol level for Sapling to stop accepting new deposits while continuing to support transactions and withdrawals; and eliminating the need to update the Consensus Branch ID with each network upgrade to reduce wallet compatibility issues. ValarDragon stated that with the combination of Tachyon and larger block capacity, a shielded transaction processing capability of approximately 200 TPS is expected. In addition, the post-quantum transparent transaction feature will introduce schemes based on SPHINCS with 128-bit and 192-bit security levels. The above content currently belongs to the upgrade ideas proposed by community members, and specific implementation still depends on development progress and subsequent NU8 discussions and voting.

According to a report by Investing.com, Citigroup has downgraded its rating on U.S. stocks, global tech stocks, and European tech stocks from "overweight" to "neutral," citing that investor positions may further decline, while upgrading European stocks (excluding the UK) to "overweight."Citigroup stated that market sentiment around AI has significantly weakened, partly due to the midterm election results raising questions about the long-term trajectory of AI spending; the Nasdaq position may shift from neutral to net short, needing to drop about 5% before it truly turns negative.Citigroup remains optimistic about AI in the medium term but will wait for positions to clear and AI sentiment to stabilize before restoring the overweight rating.

According to CoinDesk, the privacy public chain Midnight has upgraded its mainnet to Ledger 9, adding support for privacy asset transfers, introducing inter-contract call execution features, and new cryptographic standards such as Keccak-256 and ECDSA.

According to Bloomberg reporter Mark Gurman, Apple's new CEO John Ternus recently spoke with software chief Craig Federighi, requesting to accelerate AI development and no longer be satisfied with merely patching Siri's existing features. Apple's next goal is to transform Siri into a truly proactive agent.Currently, Siri can understand screen content, read user-authorized emails and messages, and perform some operations across applications, but it essentially still listens to one command and executes one action. Apple hopes it can remember tasks assigned by users over the long term, like ChatGPT Dots and Meta Muse, proactively check for changes, determine what to do next, and continue to push forward in the background.Devices like the iPhone, Mac, and Apple Watch carry a large amount of personal information, and Apple also controls the operating system and application calling interfaces. Earlier this year, Apple announced that the number of active devices worldwide has exceeded 2.5 billion, but not all devices support the new version of Siri. Gurman stated that Apple could launch a version closer to a personal agent as early as 2027; if issues regarding autonomous planning, background execution, and permission security are resolved, Siri has the opportunity to become the personal agent entry point on iPhone and Mac.

Despite the panic in the market caused by stricter regulations on data centers after the Democratic Party gained control of Congress, Goldman Sachs has raised its forecast for U.S. data center construction spending, increasing the 2026 expectation from $67 billion to $80 billion, and from $87 billion in 2027 to $100 billion, while also predicting for the first time that it will reach $125 billion in 2028.Goldman Sachs pointed out that there are currently about 86 GW of data center projects under construction in the U.S., with approximately $900 billion in high-confidence projects awaiting construction, indicating that the overall construction cycle remains resilient. The demand and backlog orders from hyperscale cloud service providers such as Microsoft, Amazon, and Google have not shown significant cooling, with H100 computing power rental prices rising 26% year-on-year and GB200 rental prices increasing by 50% since the beginning of the year.In response to the data center moratorium proposed by Texas Governor-elect Gina Hinojosa, Goldman Sachs believes that its impact is more about delaying project delivery rather than directly canceling construction plans, but it may lead to increased financing costs, reduced tax incentives, and some clients canceling contracts. Goldman Sachs also warned that the overall growth prospects of the industry need to be distinguished from the survival capabilities of individual developers, as highly leveraged data center developers may face severe financial pressure due to project delays and rising financing costs, with some companies potentially unable to last until their projects go into production.
