Action Items & Next Steps
Fusaka
- Move forward with EIP-7907 with the following PRs:
- Include 7907 in devnet-3 and stress test implementations
- Decide on requiring
eth_config(EIP-7910: eth_config JSON-RPC Method) before devnet-3 on Monday’s ACDT call - Remove
maxBlobsPerTxfrom EIP-7892 and hard a constant limit of 6 blobs/txn in EIP-7594- @FLCL to open a PR
- Increase the modExp gas cost with this PR: Update EIP-7883: Triple price by marcindsobczak · Pull Request #9969 · ethereum/EIPs · GitHub
- Tim to reach out to Matter Labs, Coinbase and Eigen to gauge impact
- Set the EIP-7918
BLOB_BASE_COSTto2**13(Update EIP-7918: finalize BLOB_BASE_COST by fradamt · Pull Request #9979 · ethereum/EIPs · GitHub) - Double the gas cost of the EIP-7951 precompile (Update EIP-7951: update gas costs for R1 verification by MariusVanDerWijden · Pull Request #9978 · ethereum/EIPs · GitHub)
Glamsterdam
- EL Headliner EIP reviews will happen on the July 31st and August 14 ACDEs
- Previously CFI’d EIPs for Glamsterdam will be moved to PFI (Update EIP-7773: Move previously CFI'd Glamsterdam EIPs to PFI by timbeiko · Pull Request #9970 · ethereum/EIPs · GitHub)
- Non headliner EIP proposals for Glamsterdam should open a PR to be PFI’d. PFI deadline will be confirmed in the next 1-2 ACDEs.
History Expiry
- All EL clients to enable pre-merge history pruning by default in their next stable release
- Teams should review the EraE draft and comment in #history-expiry
Summary
1. devnet‑2
- Finalization stalled (~56 % participation): fork‑ID mis‑calculation in Besu, 4‑byte IDs mishandled by Nethermind; EL/CL Nimbus unable to sync.
- Agreed on a standardised Genesis‑config RPC so devnets catch divergent parameters before launch; no client objects, all to estimate effort by Monday’s testing call.
- Devnet‑2 will remain up only as a bug‑hunt sandbox; Devnet‑3 becomes the “happy‑path” network.
2. EIP‑7907 (Meter contract size & raise limit)
- New limit 48 kB (2× current), down from the early “10×” proposal; code‑size index optional, NOT in consensus.
- Inclusion gate: three PRs (clarification, patch removing code‑size warming, large‑contract fix).
- Stress‑test methodology: spammer tx + large‑block replay in Devnet‑3; pull the EIP if DOS issues surface.
3. Blobs‑per‑Transaction Debate
- Status‑quo complexity (6 → 12 jump inside BPO schedule) deemed pointless.
- Decision: hard cap = 6 in PeerDAS; no BPO knob. Simple, less brittle, matches current L2 behaviour (Base averages <1.5 blobs/tx).
- Base‑fee update fraction remains in BPOs – valuable future lever; removal would create awkward special‑cases when tuning throughput.
4. Precompile Re‑Pricing
- ModExp (EIP‑7883): triple cost; beats worst‑case at 100 M gas limit. Consensus that performance‑first outlook outweighs small fee hike for a handful of power users (Matter Labs, EigenDA, Coinbase wallets).
- secp256r1 / r1 curve (EIP‑7951): 2× bump to keep parity with EC ADD/MUL. No opposition.
- Clients still free to pursue GMP / gnark acceleration, but gas schedule will assume “slow” path.
5. History Expiry Roadmap
- EraE → single EL‑centric archival format (headers, bodies, receipts in columnar chunks + optional Merkle proofs). Supersedes Era‑1, avoids consensus‑layer cruft.
- Once Era‑E spec is frozen and files generated, clients may prune history up to Cancun; rolling expiry research continues in parallel.
6. Glamsterdam Scheduling
- Headliner proposal window closed (20 Jun). EL headliner reviews on July 31 & August 14 ACDEs.
- forkcast.org launched – comparative matrix of every headliner & stakeholder impact; authors invited to update their rows.
