Ethereum sets Glamsterdam Sepolia test for Oct. 6 as developers warn fake builders could stall the chain

Ethereum core developers have scheduled the first public test of the Glamsterdam upgrade on the Sepolia testnet for Oct. 6, with the Hoodi testnet tentatively set to follow on Oct. 27. Alongside the timeline, developers flagged a specific weakness tied to the economics of free testnets: an attacker using multiple fake identities and free Sepolia ETH could repeatedly win block auctions with outsized bids and then fail to deliver the required payload data. That could interrupt block production and make it harder to tell whether problems seen during testing come from the upgrade itself or from malicious interference. According to comments made during Thursday’s core developer call, consensus-layer developer Potuz said someone could spin up large numbers of builders, rotate identities, submit extremely high bids, and provide no payload at all. Developers stressed that such an attack would not put Ethereum mainnet funds or transactions at risk, because the issue is specific to Sepolia’s free and easily sybiled environment. The concern is operational rather than financial: stalled tests, missing payloads, and a compressed release window could slow infrastructure validation and leave the upgrade further away from mainnet readiness.

Ethereum’s EIP-8198 aims to make block times adjustable before shortening them

Ethlabs is making the case for EIP-8198, or Quick Slots, as a way to speed up Ethereum without trading away censorship resistance, decentralization, or credible neutrality. The proposal would first remove the hard-coded 12-second block assumption from clients and specifications, then let the network shorten slot times in measured steps, starting with a move from 12 seconds to 10 seconds. Supporters interviewed by Ethlabs — including DeFi founders, infrastructure builders, and researchers — argue that fresher state updates could improve DEX execution, tighten quotes, reduce risk for arbitrageurs and market makers, and make tokenized assets and cross-rollup interactions work better on Ethereum’s base layer. They also say faster slots could strengthen censorship resistance, especially when paired with FOCIL, by increasing how often censored transactions get another chance to be included. At the same time, the proposal’s backers stress that none of this is worth doing if it raises barriers for geographically distributed validators or pushes staking and block production toward better-connected data centers. Work is now focused on turning the specification into running client code, testing transition paths, auditing downstream systems that assume 12-second timing, and checking compatibility with future consensus changes such as decoupled consensus.

XRP Ledger Batch V1.1 expected to go live after Sept. 29

Ripple said asset managers and other commercial projects are preparing to use the XRP Ledger Batch V1.1 upgrade as the amendment moves closer to activation. The update would allow as many as eight transactions to be bundled into a single operation, with all of them either succeeding together or being canceled together, a design meant to prevent partial execution. According to the update, the amendment has received support from 30 of 35 tracked validators. If support stays above 80% over the next 14 days, the upgrade is expected to activate after 14:06:41 UTC on Sept. 29. The timeline puts the proposal into its final countdown phase, with activation dependent on validator backing holding at the required level through the full period.

Ethereum Sets Glamsterdam Test Dates, Warns Fake Builders Could Jam Sepolia

Ethereum developers have set Oct. 6 for the public Sepolia test of the network’s upcoming Glamsterdam upgrade, but the date was confirmed alongside a blunt warning: attackers using free test ether and disposable builder identities could repeatedly win block auctions and then refuse to deliver transaction payloads. Developers said the issue would not put mainnet funds at risk because the attack targets Sepolia, where test ether carries no meaningful cost. The bigger concern is that missing payloads could freeze traffic on the test network and distort the infrastructure testing needed before the upgrade can move closer to mainnet. The warning was raised during Thursday’s core developer call, where consensus developer Potuz said an attacker could spin up large numbers of builders, rotate identities, bid aggressively and then fail to produce payloads. Glamsterdam is designed to let Ethereum fit more activity into each block while keeping verification manageable, with changes aimed at supporting a block gas limit of about 200 million. Client teams now have until Sept. 29 to ship Sepolia-ready software, leaving only seven days before the fork instead of the usual 14-day review window. A Hoodi public test is tentatively planned for Oct. 27, while a mainnet activation date has not been set.

Ethereum Targets End-2029 for Quantum-Safe Upgrade, Flags Key EIPs for Hegotá Fork

Ethereum has set a December 2029 target for making Layer 1 quantum-safe across the execution, consensus, and data layers, according to a priority list for the Hegotá upgrade released by the Ethereum Foundation’s protocol team and reported by The Block. Two proposals were placed in the top-tier “must ship” category. On the consensus side, FOCIL (EIP-7805) was marked as essential because it would require inclusion of public mempool transactions, a change aimed at improving censorship resistance. On the execution side, Frame Transactions (EIP-8141) received the same priority. The proposal would split a transaction into programmable “frames” covering validation, gas payment, and execution, laying groundwork for native account abstraction, custom signatures, and gas sponsorship while improving readiness for a post-quantum environment. The protocol team also said that starting with the “Glamsterdam” fork in the fourth quarter of 2026, subsequent forks would need to be completed at an average pace of about 7.2 months to reach a minimum viable post-quantum security milestone before the roughly 2030 “Q-day.”

TAO Surges 13% in 24 Hours as Bittensor Rolls Out Protocol Upgrades

Bittensor's TAO jumped 13.48% to $267.39 according to HTX, following the introduction of Root Reborn protocol adjustments that enhance staking and capital allocation in its subnet ecosystem. The project also expanded to Robinhood Chain via Chainlink CCIP.

Anza moves to remove floating-point math from Solana core protocol to reduce consensus split risk

Anza said it is removing floating-point operations from the Solana core protocol in stages, a change aimed at preventing consensus divergence caused by inconsistent rounding across environments. The first upgrade, SIMD-0391, has already been activated on mainnet beta at epoch 1026. It replaces floating-point operations with fixed-point arithmetic in the Stake Program and in validator client warmup and cooldown logic. A second proposal, SIMD-0607, has been submitted and is now under review. That change targets the runtime itself and would remove floating-point operations from the code paths used to calculate inflation rewards and rent. According to Anza, floating-point behavior can vary across hardware, validator clients, and compilers, which may lead to different rounding outcomes. Those differences can in turn create consensus divergence and pose risks to network liveness. The company said standardizing on fixed-point arithmetic is intended to eliminate that class of risk, and that additional floating-point paths will be addressed later.

Christine D. Kim says Bitcoin Core v32 is feature-frozen, with release expected in October

Bitcoin Core v32 reached feature freeze on Aug. 20, according to Protocol Watch founder Christine D. Kim, with developers now focused on bug fixes and smaller optimizations ahead of a planned release in October this year. The update includes several performance and operational changes inside the software rather than any change to Bitcoin’s network rules. Kim said the release can raise block validation speed by as much as 3x through parallel processing across multiple CPU cores. It also adds a global transaction queue and rate limiting, changes aimed at improving node stability during sudden spikes in transaction activity. Another addition is a fee estimation mechanism based on mempool conditions, which is intended to reduce fee overestimation. She also said the v32 update does not include changes to protocol rules at the Bitcoin network layer. The current development stage centers on fixing bugs and making limited refinements before the formal launch.
