Ethereum developers set Glamsterdam for Sepolia on Oct. 6, but bugs leave timeline uncertain

Ethereum developers confirmed during the ACDC #186 call that the Glamsterdam upgrade is scheduled to activate on the Sepolia testnet at 13:53 UTC on Oct. 6, according to Christine D. Kim. The date, however, is not fully locked in. The latest private test network, Glamsterdam-Devnet-9, has not yet reached stability, and developers identified a serious consensus-layer flaw that could halt block production across the network. On the execution side, EIP-8037 also has a bug that still needs to be fixed. A Devnet-10 release is planned in the coming weeks, and if that environment remains unstable, the Sepolia activation could be delayed. The activation schedules for the Hoodi testnet and Ethereum mainnet have not been determined. As a result, the goal of launching the upgrade on mainnet before the end of the year remains uncertain.

BNB Chain Sets Lorentz Hard Fork Mainnet Activation Schedule, Targets 20% Gas Cost Reduction

BNB Chain developers have announced the mainnet activation schedule for the Lorentz hard fork, set to execute at block height 42,100,000. The upgrade includes BEP-341, which changes transaction priority and aims to reduce gas costs by approximately 20%. Validators and node operators must update their software before the trigger height. The optimization is crucial for retail, DeFi, and other fee-sensitive activities on the network. This hard fork represents ongoing infrastructure improvements with competitive implications.

XRP posts 37% gain in August, its best month since the SEC settlement

XRP rose 37% in August, marking its strongest monthly performance since the settlement with the U.S. Securities and Exchange Commission, according to Techub News, citing Crypto.news. The report said the move was driven mainly by record ETF inflows, which have become the market’s main pricing factor for now. Techub added that current price action reflects momentum from those inflows rather than the impact of an upcoming mainnet upgrade scheduled for Sept. 11. The upgrade is expected to strengthen Vaults, automated market maker (AMM) functions, and lending protocols to support institutional use. In other words, the report says ETF-driven demand has taken center stage, while the technical upgrade has not yet been fully priced in by the market. No additional price targets or volume figures were disclosed in the source material.

TRON opens vote on Proposal No. 107 to expand TVM compatibility with Ethereum upgrades

TRON super representatives have launched voting on Mainnet Committee Proposal No. 107, with the ballot scheduled to close at 14:00 Singapore time on Aug. 28. The proposal would enable a set of features in GreatVoyage-v4.8.2 aimed at improving the TRON Virtual Machine’s compatibility with Ethereum’s Prague and Osaka upgrades. The planned changes include support for historical block hash queries, the addition of the CLZ instruction, a secp256r1 precompiled contract for Passkey verification, and lower energy consumption for MODEXP. If approved, the proposal would move TVM closer to Ethereum’s latest upgrade set and improve support for smart contract development and cross-ecosystem adaptation. The vote is being conducted through TRON’s super representative governance process.

BNB Chain says Pasteur hard fork is now live on BSC mainnet

BNB Chain said in a post on X that the Pasteur hard fork has gone live on the BSC mainnet today. The upgrade includes three proposals covering bridge security, validator governance rules and execution efficiency. According to the announcement, BEP-682 fixes a flaw in the cross-chain bridge verification process that allowed validator signatures to be counted more than once. BEP-695 defines authority and slashing rules after validator key rotation, closing a loophole that previously allowed governance voting blacklist restrictions to be bypassed. BEP-675 lets block builders submit blocks that have already been executed, with the aim of reducing repeated computation by validators. BNB Chain also shared testnet figures for the upgrade. It said throughput increased to 2324 TPS from 1237 TPS, while block production speed and gas fees remained unchanged.

BNB Chain to activate Pasteur hard fork on Aug. 25

BNB Chain is set to activate the Pasteur hard fork on its mainnet at 02:30 UTC on Aug. 25, according to Techub News. The upgrade introduces three proposals under BEP-673: stronger bridge verification, secure validator key rotation, and higher block capacity. Pasteur had already gone live on the testnet on July 21. One of the included changes, BEP-675, is expected to raise block throughput from 1,237 TPS to 2,324 TPS. U.Today said the move is aligned with BNB Chain’s roadmap for the second half of 2026, which targets another doubling of mainnet throughput and broader long-term performance improvements.

Solana to activate first mainnet slot-time reduction, cutting interval to 350 ms

Solana is preparing to activate its first mainnet upgrade to shorten slot time, according to Brennan Watt, a core Solana developer and CEO of Anza. The change is expected to reduce block production time from about 400 milliseconds to 350 milliseconds, with formal effect beginning at Epoch 1020. Watt said developers should watch for transition issues because some SDK constants, including DEFAULT_MS_PER_SLOT, have not yet been updated to reflect the new setting. An official release with the revised values will be published after the feature is activated. He also said the rollout uses a delayed activation model: the feature enters a pending state in Epoch E, activates in Epoch E+1, and only becomes fully effective in Epoch E+2. Applications that rely on SDK constants matching actual mainnet slot timing may need extra compatibility logic during the transition, such as switching behavior at epoch slot boundaries. Over the longer term, Watt said Solana plans to move these network parameters on-chain so clients can query them directly. He added that most nodes are expected to hit the target of a two-slot delay in most cases, and related limits are set to be loosened further in Anza v4.3.

Solana to Cut Slot Time to 350 Milliseconds at Epoch 1020

Solana core developer and Anza CEO Brennan Watt said the network is activating its first slot-time reduction on mainnet, with block production time expected to move from about 400 milliseconds to 350 milliseconds. The change is set to take effect at Epoch 1020. Watt warned developers about a transition period, saying some SDK constants, including DEFAULT_MS_PER_SLOT, have not yet been updated. He said the team will publish a version with the new values after activation and advised applications that rely on SDK timing constants to add fallback logic during the transition. Watt also said Solana plans to move these network parameters on-chain in the long run, so clients can query them directly. For now, the team needs to complete this upgrade first. He said the process resembles Solana’s early days of "difficult but fast iteration," and added that most nodes are expected to hit a two-slot delay target in most cases. Those limits will be relaxed further in Anza v4.3.
