According to Serenity, Jensen Huang is almost irreplaceable for Nvidia. Serenity stated that this is similar to how Tesla's valuation and market confidence could collapse if it lost Elon Musk.Serenity mentioned that Jensen Huang bet on CUDA before the explosion of artificial intelligence and began building the Neocloud ecosystem; he locked in key supply chain capacity years in advance and launched rack-level systems that integrated components like CPUs and networking devices. Jensen Huang also transformed the competitive threat posed by ASICs into new development opportunities by investing in companies like Marvell and MediaTek, competing with Broadcom, while incorporating these partners into Nvidia's NVLink ecosystem.Serenity also stated that Jensen Huang almost single-handedly built the financial and industrial ecosystem surrounding the current AI investment boom, growing Nvidia from a startup into a company with a market value exceeding $5 trillion, with an expected future growth rate of 70% by fiscal year 2028. Serenity indicated that even if Nvidia's actual revenue or product roadmap does not undergo substantial changes in the next two years, simply replacing Jensen Huang could have catastrophic effects on Nvidia's long-term development.

Pioneer of the cypherpunk movement and co-founder of Blockstream, Adam Back, stated on CNBC that he personally bets Bitcoin will reach $1 million by 2028.Adam Back pointed out that there is still about 95% of potential adoption space for Bitcoin that has not yet been unlocked, and large capital pools such as pensions and mutual funds have not yet allocated Bitcoin on a large scale. He believes that as institutional adoption continues to rise, the price bottom of Bitcoin will also show a long-term upward trend.

Blockstream CEO and co-founder Adam Back stated in an interview with Bitcoin Magazine that the "first wave" of Bitcoin adoption came from individual investors, the "second wave" comes from spot ETFs, while the "third wave" of large-scale capital inflows from pensions, managed funds, and model portfolios has yet to arrive. He pointed out that Swiss banks are preparing for this phase.According to the chapter arrangement of the interview, the discussion also covered the demand for quantum-secure Bitcoin custody by Swiss banks, comparisons between tokenized money market funds and stablecoins, tokenized stocks based on the Liquid network and Blockstream AMP, as well as the obstacles that institutions still face when entering the market.In addition, Adam Back discussed whether institutions should build their own custody capabilities or rely on third-party custodians, how regulation shapes the Bitcoin custody landscape, and the impact of Basel rules on the costs of institutions holding Bitcoin. Blockstream recently established an office in Lugano, Switzerland, and began offering consulting services.

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.

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.
