Due to the ChainSecurity report revealing compatibility and security issues with EIP-8037 and certain smart contracts, core developers decided last week to postpone the Hoodi testnet upgrade to Glamsterdam. The issues identified so far include: the remaining Gas during transaction execution may increase, leading to underflow in some Gas counting logic and triggering rollbacks, or causing code paths that should not be executed to be triggered, making the transaction appear successful. Additionally, some contracts may underestimate usage due to the inability to correctly calculate Gas consumption during calls.ChainSecurity previously stated that 13 real cases have been identified and they are responsibly disclosing this information to the affected projects. Toni Wahrstätter mentioned that this week they will further investigate the relevant contracts and assess subsequent solutions, which may require collaboration among application developers, core developers, auditors, and node operators. In the worst-case scenario, adjustments to the protocol specifications may be necessary. He reminded application developers and auditors to check the compatibility of contracts with EIP-8037 and EIP-8038 and to report issues in a timely manner.

Binance founder CZ tweeted that there are concerns about artificial intelligence attacking cryptocurrencies, but the encryption technology relied upon by the internet and banking systems is weaker.He pointed out that artificial intelligence can cause harm without cracking Bitcoin's cryptography, and the leaked data has fueled more phishing and social engineering attacks, reminding users to pay attention to security.

On October 22, the smart contract security company ChainSecurity announced that the Glamsterdam hard fork on the Ethereum Hoodi testnet has been postponed. Researchers stated that security impacts have been found in existing contracts and identified 13 real cases, and they are currently conducting responsible disclosure with the affected projects. The announcement requests teams to review the contracts, and the Ethereum Foundation is assessing the scope of the impact; the announcement did not name the projects, provide contract addresses, or give an alternative fork date.The related issues involve contracts that continue execution after capturing failed external calls. Under the reviewed gas changes, the failure handler may complete execution, whereas it would previously roll back due to gas exhaustion. The caller can deliberately provide insufficient gas to complete the target operation, but enough to allow the outer contract to record a permanent failure, causing operations that could have been retried to lose their recovery path.The technical disclosure reviews EIP-8037 and EIP-8038 from the version specification dated October 13, where the gas examples described are for proposed execution behavior. The state-gas reservoir will be fully passed with the call, and forwarding restrictions apply to execution gas, with gasleft() only reporting the execution balance. According to the reviewed rules, clearing storage slots that start at zero at the beginning of a transaction can replenish up to 97,920 execution gas; intermediary contracts may also credit back the accounted state-creation fees upon REVERT and return them to the caller.

Dmitry Gusakov, the engineering lead of the Ethereum liquid staking protocol Lido, warned at the developer conference ACDC #189 that the one-time builder access mechanism introduced by the Glamsterdam upgrade could interfere with the existing deposit protection logic of the staking protocol, leading to the hijacking of staking deposits. This issue involves multiple deposits sharing the same validator public key.According to Ethereum's current deposit rules, the first valid deposit determines the withdrawal credential, and staking protocols typically leverage this feature to prevent credential manipulation, such as initially depositing a small amount of ETH and then topping up the remaining funds once the expected credential appears. However, the special access mechanism introduced for builders by Glamsterdam may change the interpretation of subsequent pending deposits under the same public key during the fork transition period, putting the staking protocol at risk of a third outcome: the validator does not appear, and the deposited ETH is credited to the builder.Lido's proposed fix is to maintain the distinction between validator deposits and builder deposits during the one-time access process. However, core developers rejected this modification on the grounds of timing, mainly because the Sepolia testnet has already been activated according to existing specifications, and the Hoodi client version is also in preparation. Changing the behavior at this point could require redeploying Sepolia and conducting additional testing. The issue affects the access process during the fork transition period, rather than the ongoing deposit processing rules, but its consequences could impact deposits waiting in the queue.

According to the Ethereum Foundation's announcement on October 16, the Glamsterdam upgrade is scheduled to activate on October 26 at 17:42:48 (UTC), which is 01:42:48 on October 27 Beijing time, on the Hoodi testnet; at that time, the block Gas limit on Hoodi will also be increased to 200 million.This upgrade includes the embedded proposer and builder separation, block-level access lists, and Gas billing adjustments. The Sepolia testnet was activated on October 6, and the upgrade date for the Ethereum mainnet has not yet been determined. Node operators need to update the execution layer and consensus layer clients before the Hoodi activation.

According to Bloomberg, AI cloud infrastructure provider CoreWeave is facing a sell-off in its stock price due to its large debt load and ongoing search for new capital, which has left some investors feeling uneasy.JPMorgan stated that although CoreWeave faces debt concerns, its business fundamentals remain strong.

At the 2026 RISC-V China Summit, Chief Scientist Meng Jianyi of Alibaba Damo Academy stated: So far, the Xuantie chips have steadily shipped over 6 billion units. Xuantie is a series of RISC-V processors launched by Alibaba Damo Academy.At the conference, Alibaba Damo Academy also released the first automotive-grade enhanced E908A chip. Meng Jianyi cited a prediction from Omida, stating that by 2030, the annual shipment volume of global RISC-V processors will grow by nearly 30% each year, and by 2030, the global market share of processor shipments will reach approximately 25%.

Binance founder CZ posted on X that spreading FUD to smear competitors for a fee would damage the credibility of one's own exchange. He stated that it is worth pondering whether users are willing to entrust their crypto assets to companies that engage in unethical business practices.CZ also mentioned that such behavior would undermine users' trust in the relevant exchanges and could indirectly provide promotional effects for the smeared competitors, even though this method may be distasteful.

Crypto analyst Ali posted that the 10-minute cycle chart of Ethereum seems to be forming an "Adam and Eve bottom" pattern. The key resistance level currently being watched in the market is the neckline around 2520 USD. If ETH can consistently close above this level, it may confirm a bullish breakout and further open up upward space, with the target area focusing on 2640 USD.

The next phase upgrade of Ethereum, Glamsterdam, was activated on the Sepolia testnet on October 6, completing block finality during the switch without any critical failures. This upgrade consists of the consensus layer Gloas and the execution layer Amsterdam, incorporating a total of 18 EIPs, designed with a gas limit of approximately 200 million, which is about 3.3 times the current mainnet limit of 60 million. The upgrade will not automatically raise the limit but will allow for larger blocks to be produced safely, with validators deciding whether to increase it.Key changes include EIP-7732, which embeds the separation of proposers and builders in the protocol, extending the time for most validators to check transactions from about 4 seconds to about 9 seconds; EIP-7928 requires blocks to include the touched state and updated values, facilitating client data prefetching and parallel validation; EIP-7954 raises the contract code limit from 24 KiB to 64 KiB; EIP-8037 increases the cost of creating new storage slots from 20,000 gas to 97,920 gas, while regular ETH transfers remain at 21,000 gas.The gas limit for the first relevant block on Sepolia was 60 million, reaching 200 million about 11 hours later and maintaining that level. Ethereum Foundation researcher Toni Wahrstätter stated that the speed at which various clients handle gas units has improved compared to before the upgrade, with Geth's execution time for a 40 million gas block reduced from about 115 milliseconds to about 30 milliseconds. The Hoodi testnet is tentatively scheduled for deployment on October 27, with the mainnet target set for the fourth quarter of 2026;

According to CoinDesk, the Ethereum Glamsterdam upgrade was activated on the Sepolia testnet this Tuesday, increasing the block Gas limit from about 60 million to nearly 200 million, more than tripling the increase.A review of over 25 consecutive test blocks showed that the actual Gas usage was around 52 million to 92 million, accounting for only 26% to 46% of the available limit, with no instances of full capacity. The upgrade also adjusted the Gas consumption method for specific tasks and the costs of storing data, requiring developers to retest applications involving specific Gas cost assumptions. The next public testnet, Hoodi, is tentatively scheduled to launch on October 27, and the activation date for the Ethereum mainnet has yet to be determined.

The U.S. Attorney's Office for the Central District of California stated that a 26-year-old man, Adam Iza, who calls himself the "Godfather," has been sentenced to 78 months in prison and must pay $23.4 million in restitution. He pleaded guilty in January 2025 to charges of conspiracy to violate rights, wire fraud, and tax evasion, and has been in custody since September 2024. This sentence will run concurrently with the 15-year sentence he received last month for an attempted Bitcoin robbery, which will not increase his actual time served.From August 2021 to April 2022, Iza hired off-duty Los Angeles County police officers as private security and admitted to conspiring with them to obtain law enforcement confidential records and personal data of individuals he had disputes with, obtaining court-authorized search warrants to track these individuals, and having the officers intimidate and threaten them. The Department of Justice stated that five former officers have been convicted for working for him, including 42-year-old Eric Chase Saavedra, who set up a security company providing these officers, and was sentenced to 21 months; 45-year-old Michael David Coberg, who assisted in extorting rivals and arranged false drug arrests, is serving a 63-month sentence. The prosecution wrote in the sentencing memorandum that wealthy individuals cannot buy "search warrants, arrests, badges, or guns" for private disputes.In another fraud case, since December 2020, Iza gained access to a Meta Business Manager account and its associated credit line, reselling it to advertising companies, with Meta clients being charged for ads they never purchased. After discovering this, Meta refunded the clients and absorbed the losses.

According to CoinDesk, Ethereum developers released version 7.2.1 of the Prysm client on Monday evening, embedding a 200 million Gas limit to complete deployment ahead of the Sepolia testnet testing for the Glamsterdam upgrade on Tuesday.Glamsterdam is the next major upgrade for Ethereum, which will first be activated on the Sepolia testnet, where developers rehearse changes using tokens with no actual value. Part of Tuesday's testing involves raising the Gas limit on Sepolia from approximately 60 million to 200 million.Gas is the unit that measures how much computational workload a single block can accommodate on Ethereum. A higher limit means the network can handle more transactions and more complex activities simultaneously, but it also places higher demands on the computers running Ethereum. Prysm is the client software used by Ethereum validators, and its previous version had completed before this setting was added to the Sepolia configuration. Therefore, validators running the old version will still produce blocks with a 60 million Gas limit unless they manually modify the parameters, which undermines the effectiveness of this capacity test.Validators running the latest version will automatically start proposing blocks with a 200 million Gas limit when Glamsterdam activates on Sepolia at 13:53:36 UTC on October 6. Ethereum has been gradually increasing block capacity to test how far it can go before running validators becomes too demanding or expensive. The 200 million setting is only applicable to Sepolia, and Glamsterdam has not yet been activated on the Ethereum mainnet.

According to The Defiant, Ostium has announced the previous loss compensation arrangements and will officially open the compensation channel this Wednesday, with a total of 3,666 damaged wallets included in the disposal scope.According to the plan, 3,321 addresses with losses not exceeding $1,000 can receive full reimbursement, meaning that this group of small-scale victims can recover all their losses.The remaining 345 wallets collectively bear at least 86% of the total loss of approximately $23.8 million. These 345 addresses with significant losses can choose one of two arrangements: either receive a one-time payment of $1,000 directly or file a proportional claim for the portion of their assets that has not yet been recovered.

According to Politico, citing three informed sources, the U.S. Commodity Futures Trading Commission (CFTC) is investigating former Illinois Republican Congressman Adam Kinzinger, related to his trading on the prediction market platform Kalshi. The relevant trades occurred between December 2024 and January 2025, completed through a Kalshi account associated with Kinzinger. He confirmed to the media that he had placed bets on contracts regarding whether he would receive a presidential pardon, while also betting on another contract about whether Biden would issue preemptive pardons before leaving office.In the final moments before Biden left office in January 2025, he issued preemptive pardons to Kinzinger and other members of the House Select Committee investigating the Capitol riot. Screenshots provided by Kinzinger show that he made a profit of $823 from approximately 25 trades, most of which were losses. He denied any wrongdoing, stating that he had been out of office for two years at the time of the bets, was neither a congressman nor a candidate, and had "no insider information." He also stated that he had read Kalshi's rules in advance and understood that they prohibit users from trading contracts directly related to their own interests. Kalshi prohibits users from betting on contracts in which they are direct participants, and the CFTC also prohibits the use of significant non-public information in its regulated markets.Kalshi had previously handled similar cases, suspending three congressional candidates in April for betting on their own campaigns, and freezing former Congressman George Santos's account, which was referred to the CFTC and the Department of Justice, leading to a lifetime ban at the end of August.

The Ethereum Foundation announced that the Ethereum network upgrade Glamsterdam will be activated on the Sepolia testnet on October 6 at 21:53:36 Beijing time, corresponding to epoch 353024 and slot 11296768. The activation date for Hoodi and the mainnet has not yet been determined.Glamsterdam combines the execution layer Amsterdam upgrade and the consensus layer Gloas upgrade. Key changes include the embedded proposer-builder separation and block-level access lists to enhance L1 throughput, as well as adjustments to gas billing to better reflect the costs of execution and state growth. Node operators must update their execution layer and consensus layer clients before activation. Contracts relying on fixed gas assumptions may need to be modified.

AMC CEO Adam Aron posted on the X platform again naming Robinhood CEO Vlad Tenev and Chief Legal Officer Dan Gallagher. He stated that Robinhood had previously expressed support for the U.S. Securities and Exchange Commission (SEC) regarding the tokenization of U.S. stocks, believing that tokenized stocks should have voting rights and that companies should have the option to opt-out.Adam Aron also pointed out that it would be very "hypocritical" if Robinhood did not apply the same principles in its overseas operations, and he urged them not to go against the SEC's stance, "do not openly disrespect and provoke the SEC."
