• EIP-8037 formally listed as CFI for Glamsterdam
• the post-quantum transaction signature breakout launches
• EIP-7778 keeps user gas accounting unchanged
• the Associated Accounts ERC merged
• Optimism's custom gas token matches native rollups

nixorokish listed EIP-8037, the state creation gas increase, as CFI in the Glamsterdam meta EIP, merged. The post-quantum transaction signature (PQTS) breakout posted its kickoff agenda, first meeting February 4. yperbasis clarified EIP-7778 leaves user gas accounting unchanged, submitted and merged. stevieraykatz's Associated Accounts ERC merged.

• Vitalik proposes native DVT staking
• worst case block size and calldata repricing for Glamsterdam
• Checkpoint #8 published
• EIP-7773 updates CFI and DFI per ACDE #228
• the temporary contract storage EIP merged

VitalikButerin proposed native DVT: the staking key is secret shared across a few nodes with threshold signatures, staying safe from slashing as long as more than two thirds of nodes work. Nero_eth analyzed worst case block size and calldata repricing for Glamsterdam. nixorokish published the Checkpoint #8 core dev recap on the Ethereum blog. EIP-7773 was updated per ACDE #228 and merged, listing EIP-7954 as CFI.

• ACDT #66 finalizes Glamsterdam CFI scope including EIP-8037
• bal-devnet-2 adds four non headliner EIPs
• gas should reflect proving cost in the zkEVM era
• a committee based FOCIL EIP
• EIP-7778 adds a gas_spent receipt field

ACDT #66: bal-devnet-2 targets late January and adds the SLOTNUM and SWAPN family opcodes, ETH transfer logs and refund free block gas accounting; Glamsterdam CFI scope was finalized, including the EIP-8037 state creation gas increase, with app developer feedback needed on dynamic costs. ladislaus0x explained how gas will reflect proving cost in the zkEVM era to prevent DoS.

• Protocol simplicity as a key to trustlessness
• separating authorization from execution
• L1 TPS above all validiums and optimiums combined
• several EIPs flagged stagnant

A quiet Sunday. VitalikButerin stressed protocol simplicity as an underrated part of trustlessness, the walkaway test and self sovereignty. A Magicians post framed authorization as a missing layer of state beneath execution. donnoh_eth noted Ethereum L1 consistently does more TPS than all validiums and optimiums combined.

• Explicit message lanes for post-quantum and hybrid signatures
• Vitalik on taking back self sovereignty and trustlessness in 2026
• a blob gas market that rewards timing games
• EIP-7778 adds a gas_spent receipt field
• a signed HTTP requests ERC

A Magicians post described a new semantic failure as AA and post-quantum or hybrid signatures coexist: one signature can be replayed or reinterpreted across ERC-1271, ERC-7913 and AA verification surfaces, so it proposes explicit message lanes. VitalikButerin listed what taking back self sovereignty and trustlessness means in 2026, including easier local full nodes thanks to ZK-EVM and BAL. potuz_eth said the blob gas market makes timing games rational.

• Migration strategies for EOAs under the quantum threat
• EIP-8105 universal enshrined encrypted mempool proposed as a Hegotá headliner
• preconfirmations plus based rollups for synchronous composability
• the Ethereum privacy livestream The Apparatus
• EIP-8024 switches to push postfix encoding

Marco López and coauthors published a paper on how EOA authorization, transactions and signature flows would migrate, and what breaks, once a quantum computer can break secp256k1. jannikluhn proposed EIP-8105, the universal enshrined encrypted mempool, as a Hegotá headliner: transactions stay encrypted until inclusion, blocking frontrunning and sandwiching. VitalikButerin wrote on combining preconfirmations with based rollups for synchronous composability.

• ACDE #228 lists EIP-7954 as CFI and declines seven EIPs
• EIP-8037 left to the next ACDT
• trust minimized transaction simulation with state proofs
• a batch priority fees EIP merged
• a transaction gas limit cap RPC method merged

ACDE #228: EIP-7954, raising the contract size limit to 32KiB, is CFI; the EIP-8037 state creation gas increase goes to the next ACDT; seven EIPs including EIP-7793 conditional transactions, EIP-5920 PAY and the EIP-8051 ML-DSA precompile were declined. Sednaoui proposed verifying transaction simulation with MPT proofs and multi node consensus so wallets need not blindly trust RPCs. etan-status's batch priority fees and EIP-7799 fee payment log merged.
