BNB Chain announced that BEP-706 has been incorporated into the Jenner hard fork upgrade, which will provide millisecond-level block timestamps to smart contracts through the deployment of a new precompiled contract at address 0x70. Previously, contracts could only read time accurate to the second via block.timestamp, and even if multiple blocks were generated within the same second, their time differences could not be distinguished.After the upgrade, developers can read timestamps in milliseconds through the new interface, while the return value of the existing block.timestamp and the second-level timing logic remain unchanged. This feature can be used in scenarios that require sub-second precision, such as quote settlements with a validity period of only a few hundred milliseconds, auction deadlines, and price oracle data update timeliness checks. The computation cost of the new precompiled contract is 20 Gas, and the call will also incur corresponding call and memory costs. BNB Chain reminds developers to pay attention to the consistency of units between seconds and milliseconds, and to check whether the call is successful and whether it returns the expected 32-byte data during integration.

Blockchain analysis company Chainalysis stated that it has confirmed that certain customer information, including the names, usernames, password hashes, and valid tokens of all Chainalysis users, was exposed to a malicious actor during this security incident. During the investigation, access to Reactor and Data Solutions was cut off by the officials. There is currently no evidence that any investigative data was accessed or that Chainalysis's attribution data was tampered with.It is reported that the officials implemented additional proactive monitoring systems to detect abnormal activities. After abnormal activities were discovered today, the KYT (User Interface and API) and other address screening products and login pages were taken offline. Customers whose KYT accounts appear to have been accessed without authorization are being directly notified.Chainalysis plans to restore access to KYT and address screening starting tomorrow. Customers can send trusted IP addresses to support@chainalysis.com or contact the Chainalysis customer team to be whitelisted. Subsequently, Chainalysis will authorize users to reset passwords and rotate API keys for transaction logging.

Immutable Chain plans to migrate to OP Stack in mid-2027, reducing block time from 2 seconds to 1 second.

Blockaid detected that the bridged token DAI.e on the Avalanche chain deviated from its pegged price, with the price in the active decentralized trading pool rising to about 1.1 USD.

According to the security agency Blockaid, the Ethereum execution client Reth and its derivative client op-reth have a state root calculation error that affects several EVM blockchains, including multiple OP Stack chains. Unfixed nodes may experience synchronization stalls or return incorrect state proofs (eth_getProof). This issue is classified as a client correctness defect and is not a known attack event; no financial losses have been detected so far.Reth merged the fix code on November 3, with the fixed versions including reth v2.10.0, op-reth v2.8.1, and Base node-reth v1.5.3. As a precaution, the cross-chain interoperability protocol LayerZero has suspended the off-chain infrastructure of some affected chains, resulting in delays for related cross-chain messages, but no messages will be lost; some protocols have also suspended deposits or cross-chain routing. Blockaid recommends that relevant node operators and RPC service providers upgrade as soon as possible.

Real estate tokenization platform GromaCorp announced the launch of GromaCoin (GRO) on Uniswap v4, which is the first permissioned asset on Uniswap's automated market maker. GRO is paired with USDC, allowing verified investors to buy, sell, issue, and redeem on-chain at net asset value. GRO is an ERC-3643 security token issued on the Base network, with KYC and investor qualification rules embedded at the token level to prevent transfers to unapproved wallets.Each GRO represents a fractional ownership in the Groma Real Estate Trust, which is a regulated real estate investment trust (REIT) in the United States, focusing on multi-family residential properties, with assets primarily located in the Greater Boston and Providence areas. The trust's total asset value is nearly $95 million, with each GromaCoin having a net asset value of $1.07, and the portfolio includes over 125 to 150 income-generating properties, paying dividends quarterly, with a current yield of approximately 3.74%.Uniswap launched the Permissioned Pools framework on July 23, 2026, allowing asset issuers to operate managed whitelists and conduct compliance checks on-chain, with unverified wallets unable to participate in trading. GromaCoin is the first asset to adopt this framework and is currently only available to accredited investors. Groma has also partnered with Birch Hill and Morpho to allow holders to borrow USDC using GRO as collateral, with an initial supply cap of $5 million for this lending setup.

The platform will gradually process requests once the relevant systems are restored and will announce the service recovery time separately.

According to Cointelegraph, VeChain co-founder and CEO Sunny Lu recently stated in Cointelegraph's Chain Reaction program that autonomous AI agents operating around the clock require a "new accountability system" to establish public trust, and that "the perfect solution is blockchain."He made this statement while introducing the AI agent platform VeWorld.ai built on the VeChain blockchain. According to his vision, AI agents will have digital "passports" and operate within a "decentralized reputation system" that tracks the reputation of agents and their creators, while smart contracts can help settle transactions between agents or between agents and people. VeChain has previously advanced blockchain applications through supply chain tracking, including food traceability projects.Lu believes that AI agents can also help individuals convert their expertise into businesses or services, expanding software development opportunities to non-developer groups. He likened this opportunity to mobile app stores, which allow individual developers to distribute and monetize their creations, while agent-building tools can open this market to people beyond programming skills, including those with professional experience, local knowledge, or hobbies.He himself has undertaken several initiatives, including creating an educational agent for his daughter, an agent to support his mother's daily routine and rehabilitation, and a virtual employee to manage procurement, inventory, sales, and operations for a shop owned by an acquaintance in Milan.Meanwhile, other industry participants have pointed out the risks of relying on agent service providers. Animoca Brands Chairman Yat Siu stated in an October interview with Cointelegraph that while crypto traders can have AI agents work around the clock, he warned users that they might build trading strategies around services they cannot control.

According to GCSA monitoring, the Global Cybersecurity Alliance (GCSA) has released three independent technical investigation reports, disclosing several recent security risks related to digital assets. Attackers impersonated security@ku.com to lure users into downloading remote control programs. GCSA found that the relevant domain names had not previously configured DMARC; after notification, KuCoin has completed rectification and enabled DMARC isolation policies.After the original MCP toolkit referenced in Bitkub's official documentation was taken down, a third party re-registered the npm package name. The installation method without a fixed version and the risk of plaintext keys may lead to credential leakage; there is currently no actual evidence of theft, and Bitkub has not yet responded to the notification.The TranchePool treasury within the Avalanche ecosystem was attacked due to a cross-day settlement logic flaw, where attackers utilized flash loans and repeated withdrawals to transfer approximately 1.0134 million USDC within 202 seconds. This incident is categorized as a vulnerability in the upper application, and the underlying network was not affected. GCSA stated that it has reported the clues to the relevant platforms and published the original analysis and evidence for industry reference.
