• EIP-8430 discussion thread
• EIP-8298 records code hashes in the BAL
• EF post-quantum hash-based signature challenge
• ethrex v28 ready for Glamsterdam
• Glamsterdam risk and governance debate

EIP-8430 (the AA transaction type split out of 8130) opened its discussion thread, explaining the split: the transaction type is useful on its own and can ship first. EIP-8298 submitted a revision (merged October 2) so `SETCODEFROM` records only the code hash in the BAL and rejects sources created in the same transaction, preventing one 9,300 gas call from adding up to 24 KiB to the BAL. The EF launched an open challenge to design stateless hash-based signatures for post-quantum Ethereum and prove them secure in Lean.

• AA transaction type split out of EIP-8130
• ERC-8421 frame transaction alternative mempools
• EIP-8141 bounds producer re-execution
• EIP-7906 assertion inputs
• FOCIL Profile 2

chunter-cb of the Base team split EIP-8130's transaction type into its own EIP (later EIP-8430). It has no Keystore dependency and works for today's secp256k1 EOAs, supporting phased call batching, gas sponsorship, 2D nonces and in-band EIP-7702-style code delegation; EIP-8130 keeps only the Keystore. EIP-8141 merged a revision bounding how much work block producers spend re-executing unapproving validation prefixes, and switched to EIP-7976 for the calldata floor. forshtat opened a discussion thread for ERC-8421 alternative mempools, calling it conceptually close to MATCHA.

• Chainlink CCIP 2.0 first to ship FCR
• ACDT #98
• 200M gas safe on execution time
• Daisugi v0.2 supports frame transactions
• EIP-8429 escalating gas for repeated calls

Chainlink CCIP 2.0 became the first bridge to put the Fast Confirmation Rule (FCR) into production, so transfers originating from Ethereum can move much faster than finality with clear security guarantees; Derek Chiang put it at 30 times faster. At ACDT #98, the 200M gas limit was deemed safe on execution time, and FCR will use a new confirmed block tag. Daisugi v0.2 added frame transaction support, so SPHINCS-signed transactions can run as native frames.

• Vitalik's "The cryptographic world computer"
• Lean consensus
• 8-second slots and 2 to 3 minute finality
• EIP-8425 draft submitted
• quick slots in Hegotá

Vitalik published "The cryptographic world computer", an attempt to concisely express the true meaning of the forks planned after Hegotá: Ethereum is no longer just a blockchain but a hybrid. barnabemonnot argued that if faster slots ship in Hegotá, 8-second slots and 2 to 3 minute finality could arrive by early 2028. EIP-8425 quantum freeze and account recovery was submitted as a draft EIP.

• PeerDAS running smoothly for nearly a year
• snap v2 sync
• EIP-7928 block-level access lists
• half-day node sync
• ERC-8427 portable spend grants

Saturday's discussion centered on the cost of running nodes. Vitalik noted you can now sync an Ethereum node in half a day, and with aggressive settings it takes under half a terabyte of disk; he also called PeerDAS running for nearly a year with basically no problems an underappreciated triumph of client developers. nero_eth described Glamsterdam's snap v2, which uses block-level access lists, essentially state diffs, to replace the traditional healing phase, making sync faster and simpler.

• quick slots merged into consensus specs
• formally verified decoupled consensus
• frames-devnet-0
• EIP-8425 quantum freeze and account recovery
• Ethereum's TCB

Two "faster Ethereum" milestones: barnabemonnot announced that quick slots (EIP-8198) was merged as a feature spec into the Ethereum consensus specs, and fradamt released a formally verified proposal for a decoupled consensus protocol in I*, targeting 4 to 8 times faster finality. ethPandaOps launched the Hegotá frames-devnet-0. Magicians began discussing EIP-8425, which would freeze and recover accounts that have not migrated to post-quantum schemes.

• ACDE #246
• EIP-8250 and EIP-8272 CFI
• EIP-7906 transaction assertions
• repricing EIP-8131 and EIP-8279
• Daisugi post-quantum testnet

ACDE #246 moved 10 EIPs to Considered for Inclusion (CFI) in Hegotá, including three companions to frame transactions: keyed nonces (EIP-8250), recent roots (EIP-8272) and transaction assertions via a state diff opcode (EIP-7906), plus refund removal (EIP-3298) and the repricings EIP-8131 and EIP-8279; EIP-8304 was declined, and EIP-8372 and EIP-8368 wait for 30 days of Glamsterdam mainnet data. asanso launched Daisugi v0.1, a post-quantum testnet using SPHINCS hash-based signatures.
