The non-profit research organization Ethlabs stated that the EIP-8037 and EIP-8038 in the Ethereum Glamsterdam upgrade involve adjustments to Gas costs and billing mechanisms, which may affect some already deployed smart contracts. Ethlabs recommends postponing modifications to the upgrade specifications or determining the fork date for the Hoodi testnet until the results of external audits are published and the relevant impacts are clarified. The final decision will be made by the Ethereum Core Developers Meeting (ACD).The two external audits commissioned by the Ethereum Foundation from ChainSecurity and Dedaub are expected to be published before November 16. On the same day, a public Q&A will be held during the ACD testing meeting. The ACD executive meeting on November 19 is expected to discuss the audit results and may decide whether to modify the upgrade specifications.Glamsterdam aims to increase the Ethereum Gas limit per block from 60 million to 200 million. Ethlabs pointed out that adjustments to Gas costs may affect contracts and tools with hardcoded operational costs, and changes in the billing mechanism may also cause some deployed contracts to exhibit unexpected behavior. For example, after an internal call rollback, the remaining Gas returned by gasleft() may actually increase, affecting the contract's judgment on whether the call failed due to Gas exhaustion.

The Solana development team Anza posted on platform X, suggesting that Solana mainnet-beta validators urgently upgrade to version Agave 4.4.1, or they will be forked out of the network.This version applies a minimum loading data limit to the loader-v3 ProgramData account, and nodes that do not install the patch are scheduled to be forked out of the network at the 1079th epoch (around 21:30 Beijing time).

The Ethereum Foundation stated on platform X that its "Strawmap" has set a goal to achieve Lean Ethereum by 2029, and a plan has now been established to gradually advance through forks. H* will be the last fork that does not include Lean features; I* will introduce leanVM and Lean transactions; J* will add Lean proofs, data availability sampling, and PCS; by the L stage, Lean Ethereum will be completed.It is reported that Lean Ethereum is a long-term protocol restructuring vision and roadmap proposed after Ethereum enters its second decade, with the core goal of streamlining the protocol without sacrificing decentralization and security, significantly enhancing performance, addressing quantum computing threats, and restructuring the underlying technology stack.

According to Decrypt, Bitcoin developer Matt Corallo stated on the MARA Foundation TV program that he estimates there is an 80% chance that the next soft fork of the Bitcoin network will be the "Big Consensus Cleanup" (BIP-54).This proposal was introduced in 2019 and aims to fix four long-standing vulnerabilities in Bitcoin's consensus rules, including issues related to the difficulty adjustment mechanism and denial-of-service attack vectors among miners.

According to the improvement proposal (PIP) disclosed by the Polygon community forum, a member proposed to zero out approximately 70.49 million native POL (approximately 6.5 million USD at about 0.0924 USD on October 29) from the addresses on the blacklist through a hard fork of the Polygon PoS mainnet and transfer it to a designated recovery address. Among these, approximately 23.86 million are related to Polymarket, and approximately 46.63 million are related to Binance, with the total supply remaining unchanged.The proposal is scheduled to be introduced at the protocol governance meeting on November 5 at 22:30 Beijing time, with the activation block and client version to be determined.

BNB Chain announced that the BEP-706 proposal has been incorporated into the Jenner hard fork, adding a precompiled contract located at address 0x70, which allows smart contracts to read the millisecond-level timestamp of the current block.Previously, contracts could only read the second-level time through block.timestamp, making it impossible to distinguish the specific time difference when multiple blocks were produced within the same second. BEP-706 allows developers to obtain the milliseconds since the Unix epoch, which can be used to improve the accuracy of time-sensitive signed quotes, auction deadlines, and price oracle update timeliness checks.This feature is an incremental upgrade and does not affect the existing second-level return mechanism of block.timestamp.

Bitcoin dual-staking protocol b14g announced recovery progress, stating that the Core network executed a hard fork today, transferring and recovering 68,146,177.22 CORE from three addresses controlled by attackers through a one-time on-chain state adjustment, which accounts for 70.2% of the 97,045,563 affected CORE from the incident on October 31.This operation did not roll back transactions, mint new tokens, or change the total supply of CORE. The recovered tokens have not yet been allocated to affected users, and the related funds held or frozen by exchanges have not been returned. b14g stated that they are still verifying balances and formulating a distribution plan, and there is currently no official claims process.

Starknet posted on platform X stating that account abstraction allows for changing the verification logic while keeping the address, balance, and history unchanged, thus switching to a post-quantum signature scheme without modifying the protocol.Starknet stated that as an Ethereum L2, its settlement, data publishing, and cross-chain bridges still rely on Ethereum and elliptic curve cryptography; researching an independent L1 would allow it to set its own cryptographic schemes and migration timelines. The independent L1 is still a research direction, STRK remains the native token, and there are currently no plans to issue new tokens. Any decision to migrate to L1 must go through a binding governance vote.

BNB Chain announced on platform X that the Jenner hard fork upgrade has been launched on the BSC testnet. The upgrade includes Payment Lane, which reserves 5% of the block gas for eligible payments by default; provides millisecond-level block timestamps for smart contracts; and introduces a new compliance asset standard CAS20.Payment Lane and CAS20 will only be fully enabled after governance, with more details to be announced later.

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.

The BNB Chain development team announced that the BNB Smart Chain testnet will undergo the Jenner hard fork upgrade on October 28. Validators, node operators, block builders, and application developers need to start preparing for the upgrade.The Jenner upgrade includes the Payment Lane feature, which defaults to reserving 5% of block Gas for eligible payments.

According to official news from IoTeX, the Zanzibar hard fork has been activated on the IoTeX mainnet (block height 53,533,081). According to IIP-59, voter rewards will be calculated and distributed on-chain during each reward cycle, eliminating off-chain services and intermediaries, allowing anyone to directly verify each payment on-chain. The first on-chain distribution will take place the following day.This upgrade also strengthens consensus by checking the proof of holding representative keys, preparing for subsequent BLS signature aggregation. Node operators need to upgrade to iotex-core v2.5.1 without the need to modify configurations or resynchronize.

Sui co-founder and Chief Product Officer Adeniyi Abiodun wrote in a review: Several years ago, when the team began to build an L1, the venture capital firms and institutions they contacted suggested that they fork EVM to avoid the difficulties of self-development and to quickly launch another version of a similar product before continuing to advance.Abiodun stated that the team rejected this suggestion because they had a clear judgment on the direction of industry development and believed that replicating a flawed design was not advisable. Therefore, Sui was built from scratch, taking on the corresponding risks and time costs. He mentioned that the current trend aligns with the team's initial judgment, and among the batch of application scenarios people hope to build today, Sui is the only viable option, making the next few years very interesting.

According to the official announcement, Binance is expected to suspend the token deposit and withdrawal services for Filecoin (FIL) on October 19, 2026, at 19:59 (UTC+8) to support its network upgrade and hard fork.The project team will carry out the network upgrade and hard fork at block height 6,470,279 (expected on October 19, 2026, at 20:59 UTC+8).

According to The Defiant, the token holders of the DeFi protocol Balancer have voted to approve the protocol liquidation plan while rejecting the proposal to launch an official fork chain.According to this liquidation arrangement, the paused liquidity pools will switch to a withdrawal-only mode starting October 30. BAL holders will need to wait until the end of May 2027, at which point they can exchange their tokens for the protocol treasury assets.

Ethereum co-founder Vitalik Buterin released the plan for "The Computer of the Crypto World," stating that the Hegota fork scheduled for next year may be Ethereum's last "regular" fork, with subsequent upgrades introducing recursive STARK, automated formal verification, optimized consensus, and quantum security capabilities.He indicated that Ethereum will transition from a blockchain to a hybrid architecture that integrates modern cryptography. This roadmap aims to shorten transaction finality to 8 to 32 seconds, significantly reduced from the current approximately 200 seconds with 12 confirmations, and will adjust verification, consensus, and block construction mechanisms through PeerDAS, SNARK, and FOCIL.

According to the official announcement from Binance, Binance will suspend deposits and withdrawals of tokens on the Base network starting from September 30, 2026, at 17:00 (UTC) to support the network upgrade and hard fork. The hard fork is expected to take place on the same day at 18:00 (UTC).During this period, trading functions will not be affected, and Binance will handle all technical matters. Deposits and withdrawals will automatically resume once the network stabilizes, without the need for further announcements.

Balancer's official X account stated: The Balancer official fork proposal led by MAXYZ has been launched on the forum, and liquidity, contributors, partners, and intellectual property may be transferred to the new protocol.This proposal is independent of the liquidation proposal. The discussion is currently open, and a Snapshot vote is expected to take place over the weekend.

Uniswap founder Hayden Adams stated on the X platform that the original domain holder of Uniswap.com had asked for a seven-figure sum, but the team refused to pay. SBF subsequently purchased the domain for a seven-figure amount and pointed it to a fork project. Due to the malicious use of the domain, the legal team ultimately acquired the domain for free.
