Odaily Report: Ethlabs published an article on the Ethereum community forum, proposing to advance Ethereum's goal of achieving quantum resistance (Post-Quantum) and AI attack resistance (Post-AI) to 2027, under the codename "pqai27," and recommending it be designated as the highest priority for protocol development. The team believes that AI is accelerating the cracking of mathematical problems and the discovery of software vulnerabilities, while the timeline for quantum computing threats is also moving up. Ethereum needs to enhance its long-term network security by adopting cryptographic schemes with fewer security assumptions, strengthening client security, and formal verification.To advance this goal, Ethlabs recommends reassessing the upgrade scope of the subsequent hard fork Hegotá, reconsidering features that are not on the critical path for pqai27, and announcing the withdrawal of the Quick Slots resources previously sought for Hegotá to redirect them toward pqai27. The preliminary roadmap vision includes: at the Hegotá stage, implementing a quantum-resistant consensus mechanism and account signature scheme to enable Ethereum to operate in a quantum-resistant manner; subsequently, achieving full-capacity operation through signature aggregation and quantum-resistant data availability solutions. Ethlabs emphasizes that achieving "pqai-ready" by 2027 is the core goal, while reaching full capacity "pqai-scaled" is a more challenging stretch objective.

Odaily reports: Ethlabs recommends not making a decision on the Ethereum Glamsterdam upgrade until the situation is clarified. The team has been monitoring and analyzing the potential impact of EIP-8037 and EIP-8038 on deployed smart contracts for more than two weeks; the results of external audits commissioned by the Ethereum Foundation and conducted by Chain Security and Dedaub are expected to be published on November 16. Ethlabs recommends not proceeding with specification changes or scheduling the Hoodi testnet fork until the audit findings are published and a clear position is formed, and calls on application developers to run the self-check tool provided by the Foundation and disclose potential issues via glamsterdam@ethereum.org.

Odaily reports: b14g has released a post-mortem report on the security incident of October 31, 2026. It states that the attacker exploited a compatibility flaw between its staking contract and the Core network's native staking contract, initiating 99 zero-amount (0 CORE) withdrawal requests across 91 staking orders in a single transaction, resulting in the theft of approximately 97.05 million CORE. The attack did not involve any private key leak, nor did the attacker modify or deploy any new b14g contract code. BTC staked through b14g was unaffected and remains locked on the Bitcoin chain.Regarding fund recovery, approximately 68.15 million CORE (about 70.2% of the total stolen) was recovered on November 2 through a Core hard fork, and another approximately 12 million CORE has reportedly been frozen by trading platforms. As for user compensation, b14g plans to return the recovered CORE within the next 5 to 7 days in proportion to the original balances of each affected order, with the remaining losses to be repaid through 50% of future Core staking business revenue, claimable by affected users on a weekly basis.

Odaily reports: Ethereum core developers have postponed the Glamsterdam upgrade fork on the Hoodi testnet until security issues involving 8 smart contract invariants are resolved. The Ethereum Foundation stated that EIP-8037 and EIP-8038 adjust the gas accounting method for certain operations, which may affect projects that rely on fixed gas cost assumptions.Smart contract auditing firm ChainSecurity released a report on October 13, pointing out that these two proposals may break smart contracts that rely on fixed gas assumptions when external calls fail. The Glamsterdam upgrade was launched on the Sepolia testnet on October 6. (Cointelegraph)

Odaily reports: The Ethereum Foundation has announced that security firm ChainSecurity recently discovered that certain invariants relied upon by some projects may become invalid after the Glamsterdam upgrade, involving adjustments to Gas costs for certain operations and state Gas accounting methods under EIP-8037 and EIP-8038. In response, the Ethereum All Core Developers (ACD) meeting decided to postpone the hard fork process and will not launch the fork on the Hoodi testnet for now, until the relevant issues are resolved.The Ethereum Foundation added that it is currently working with multiple audit firms to conduct reviews and carrying out internal audits, but cannot cover the on-chain and off-chain code of all projects. Therefore, it calls on contract developers and auditors to check whether their projects depend on the relevant 8 invariants. A dedicated GitHub repository has been created for this purpose, providing invariant descriptions, examples, and prompts that can be used for project self-assessment, in order to evaluate the potential impact of the upgrade and potential specification adjustment proposals.

Odaily reports that Immutable has announced that Immutable Chain plans to upgrade from a custom geth fork to an OP Stack-based chain in 2027. After the upgrade, on-chain transaction speeds will be faster, and the chain will establish a closer connection to Ethereum's security; all accounts, balances, and contracts will be migrated automatically, requiring virtually no action from users.

Odaily: Binance and Polymarket have proposed implementing a hard fork on the Polygon network to recover approximately 70.49 million stolen POL tokens, valued at about $6.8 million. Of these, Polymarket-related addresses account for 23.86 million tokens, while Binance-related addresses account for 46.63 million tokens. The tokens are planned to be transferred from 5 attacker-controlled addresses to verified recovery wallets designated by the two platforms, without changing the total POL supply.Polygon block producers have already blocked transactions from the affected addresses, but this restriction is only a temporary measure and cannot return the funds to their owners. The plan requires governance approval and must first be tested on the Polygon Amoy testnet, with discussion expected on November 5. The mainnet hard fork date has not yet been determined.
