# Weekly Ethereum Research Report (2026-05-11 ~ 2026-05-15)

## TL;DR

- **Bottom line**: The Svalbard Interop wrap-up and EF blog accelerated the Glamsterdam spec-freeze flow, while Hegota was formalized as the next hard-fork track with EIP-7805 FOCIL as the CL Headliner.
- **Numbers**: From 5/11~5/15, 7 protocol calls were held; on 5/13, 6 calls overlapped; and the Reth peer ratio for Besu instances rose from ~75% to ~96% over 2 weeks.
- **Action**: Operators and researchers should track together the 5/18 close of 5 Lido Snapshots, 5/20 P2P Networking #1, 5/21 ACDE #237, and the Lido Tokenholder Update Call.

## Top 3 Takeaways

1. **The official Svalbard Interop wrap-up pulled Glamsterdam specs into freeze stage within a single week, and the "Hegotá" codename formally entered as the next hard fork.** On 5/11, the ACDE #237 (5/21, 10 days ahead) agenda titled "Glam / Hegotá" exposed in advance a 90-minute call for simultaneous decisions on the two hard forks. On 5/12, the EF blog [Protocol Cluster Updates: May 2026](https://blog.ethereum.org/en/2026/05/11/protocol-update-may-26) officially bundled four decisions after a 9-day hiatus: FOCIL EIP-7805 Hegota CL Headliner confirmed + 200M Gas Limit Floor consensus + EIP-8037 `fixed cost_per_state_byte` adopted + Native AA scoping completed. The same day, [commit ffebcbc](https://github.com/ethereum/EIPs/commit/ffebcbc15d49445bbc8d59021d85484ef9d7a69c) batch-promoted the EIP-7773 Glamsterdam Meta to SFI (Scheduled for Inclusion) for 8 EL EIPs (EIP-7708 / EIP-7778 / EIP-7843 / EIP-7954 / EIP-7976 / EIP-7981 / EIP-8024 / EIP-8037). On 5/13, Glamsterdam Repricings #7 (14:00 UTC) was a spec-freeze decision call with the phrase "Final decision" stated twice, and 5 paired-spec burst commits for EIP-8037/EIP-8038 followed over the 2 hours and 47 minutes immediately before/after. This flow was a **3-day cycle** from 5/10 CFI to 5/12 SFI to 5/13 Final Decision, compressing candidate-pool concretization through the spec-freeze stage into one week. On 5/14, ACDC #178 proceeded with two agenda items, "glam + hegotá", and became the official starting point for the transition from Glamsterdam to Hegotá by reaffirming EIP-7805 (FOCIL) as the Hegotá CL Headliner and formally discussing EIP-7716 (Correlated Downtime Penalties) and EIP-8205 (Validator Pre-registration) as Hegotá CL candidates.

2. **Two governance standardization tracks and one DVT permissionless-entry acceleration track appeared simultaneously in one week.** On 5/11, the EIP-8261 "Gas Limit Schedule (`gpo`)" proposal ([eth-magicians 28494](https://ethereum-magicians.org/t/eip-8261-gas-limit-schedule/28494), bbusa) received an official EIP number on 5/13, within 24 hours. The proposal removes four mechanisms in one batch: validator "preferred gas limit" via `engine_forkchoiceUpdated`, EL `--miner.gaslimit` flag, builder bids `gas_limit`, and the EIP-1559 ±1/1024 per-block adjustment rule; it introduces the `gpo<index>` fork pattern (isomorphic to EIP-7892 BPO). As a result, it is a line that elevates the 200M Gas Limit Floor from a mere recommendation to a consensus-enforced parameter, while standardizing Curated Operator governance authority from Lido NOM governance into the ACD cycle. On 5/13, 5 Lido DAO Governance May 2026 Snapshots were proposed simultaneously ([Lido X](https://x.com/LidoFinance/status/2054519728668897658), 11:10 UTC), bundling NEST LDO automated buyback, CMv2 Node Operator Type Assessment Framework, GateSeals → CircuitBreaker permanence, Pier Two/MAVAN re-approval, and LOL Easy Track limit. The 5 votes close together at 5/18 16:00 UTC and align with the 5/21 Tokenholder Update Call result amplification, creating a **formal standardization of Curated Operator entry assessment criteria + emergency-halt mechanism permanence narrative**. The same day, [Lido Research 11559](https://research.lido.fi/t/proposal-additions-to-the-lido-ics-framework-to-streamline-the-ssv-community-nos-path-to-verification/11559) (GBeast) posted a proposal to add scoring sources to the SSV Community NO ICS framework: SSV pre-VO KYC grants +4 points to Proof of Humanity, and SSV High Signal score grants +2~5 points to Proof of Engagement. This means accelerated Lido CSM/ICS qualification for DVT operators and the first visibility of the Lido NO pool's triple-track governance structure (Curated v2 / CSM-ICS / SDVT).

3. **The week hit a peak of 7 calls plus 6 simultaneous calls on 5/13, but official notes are unpublished for all 7; meanwhile autonomous P2P topology drift and a 45-day client-release gap accumulated as infrastructure risk.** From 5/11~5/15, 7 calls were held — ACDT #079, FCR #007, PQTS #008, Repricings #007, PQI #039, L1-zkEVM #004, and ACDC #178 — but 0 official notes were published (14 cumulative unpublished / longest ACDC #176 D+57). On 5/13, there were 6 calls on a single day, with 2 simultaneous 13:00 + 14:00 calls and 2 simultaneous 15:00 calls causing heavy listener fragmentation, while ACDE was absent (next ACDE #237 is 5/21). [Stereum Labs 36-node fleet week-2 measurements](https://ethresear.ch/t/el-peer-composition-drifts-on-a-fixed-software-baseline-two-week-comparison-on-a-36-node-fleet/24857) (5/12 12:13 UTC, stefa2k) showed that, on the same EC/CC, same hardware, and same Reth release baseline, the Reth peer ratio for Besu instances autonomously accelerated from ~75% to ~96% (+21%p). Also visible were ~8x asymmetric over-representation versus Reth network share of ~12%, Reth fleet connected peer ~123 → ~69 (-44%), and tracked peer table ~7,400 → ~2,506 (-66%). This quantitatively exposed the limits of standard client-diversity metrics (node-count ratio) and aligns with the newly created 5/20 P2P Networking #1 (15:30 UTC) call as a signal that peer-link-unit entropy monitoring is needed. The EL/CL client release gap is now **45 days**, with Geth v1.17.2 CVE-26313/26314/26315 and Lighthouse v8.1.3 state root 10x regression CRITICAL still unresolved. Through 5/14, EIP upgrade status data showed 11 consecutive days of rotating drift, and the recommendation to migrate `scripts/fetch_forkcast.py` pagination remained cumulatively delayed.

### AA Track + ECDSA Authority Deactivation (Paired Spec Stabilization)

| Item | This Week's Change |
|------|-------------|
| EIP-8141 (Frame Transaction) | 5/12 [`235d505`](https://github.com/ethereum/EIPs/commit/235d5056eea9df33be7517a9c48872cd2eca2971) "Frames cleanup #11621" (lightclient) → 5/13 [`#11652`] "Support atomic batching with any frames" (Derek Chiang) -- AA UX complement by bundling multiple operations into a single transaction |
| EIP-8250 (Keyed Nonces for Frame Tx) | 5/12 [`326c463`](https://github.com/ethereum/EIPs/commit/326c46310b8f484ca68b266d173c9e4c750d3515) new registration -- 192-bit key + 64-bit seq 2D nonce / Vitalik endorsed it as a "potential first foray into new state scaling strategy" (previous-week tracking line) |
| EIP-8130 (Casper FFG simplification / presumed PQ verifier) | 5/12 [`0aa63ce`](https://github.com/ethereum/EIPs/commit/0aa63ce40eaf82dcf91d8010bb3bb56cc4a58513) "Move from to sender" + [`75eb6b4`](https://github.com/ethereum/EIPs/commit/75eb6b4c5fc44bfb23b1177d2f11d89189ea10be) "Add canonical verifier set" → 5/13 "Tighten verifier allowlist" + "Update gas and verifier validation" 2 commits -- yesterday's note hypothesis of a two-way AA headliner race is reinterpreted through the EF blog phrase "Native AA scoping", while EIP-8130 is a separate PQ verifier or Casper FFG simplification track |

### Infrastructure / RPC / Other

- EIP-7594 PeerDAS Cell-level deltas + EIP-8070 eth/72 Sparse blobpool + Ethp2p updates -- the three sessions in the newly created 5/20 P2P Networking #1 (15:30 UTC) call ([eth-magicians 28500](https://ethereum-magicians.org/t/p2p-networking-1-may-20-2026/28500)) are a signal that the specialized P2P layer track is becoming independent
- **RPC Standards #26** (5/18 15:00 UTC) newly registered ([eth-magicians 28522](https://ethereum-magicians.org/t/rpc-standards-26-may-18-2026-15-00-utc/28522)) -- (a) `eth_simulateV1` error handling relaxation, (b) `debug_getRawTransaction` standardization (PR #791), (c) uncle count method removal (`eth_getUncleCountByBlockHash` / `eth_getUncleCountByBlockNumber`, **Breaking Change preview**), (d) EIP-7910 agenda

- **BondRoute "Application-Layer Execution Bonds"** -- new ethereum-magicians discussion on 5/11 / bond + slashing-based solver guarantee mechanism / critique of trust boundaries in existing MEV defenses (private mempool / relay / solver)

---

## 2. EIP Status Changes (Monday vs Friday)

> **Data Integrity Warning (LEVEL 3+ accumulated for 12 days)**: From 5/4~5/14, forkcast snapshots maintained a 246-item quota for 11 consecutive days while 1~4 EIPs rotated in/out daily (rotating snapshot drift). The EIP-5920 PAY opcode toggled 6 times over 11 days (average 1.8-day cycle). Hypothesis: the forkcast repo `src/data/eips` directory has more than 246 files, and a single GitHub `/contents` API call is truncated to the first ≈246, returning a different EIP set each day. Migration of `scripts/fetch_forkcast.py` to pagination (`per_page=100` + `page` loop) or the Trees API (`/git/trees/{sha}?recursive=1`) has been delayed by 5 days. Forkcast citations in this section trust only results cross-verified across four sources: ACD call notes + GitHub commits + ethereum-magicians discussions + EF blog. **Mainnet Final facts are unchanged** (EIP-2537 / EIP-2935 Pectra Included + EIP-4844 Dencun Included remain).

### 5/11 → 5/15 forkcast Snapshot Toggle (Single-File Diff)

| Hard Fork / Stage | Added | Removed |
|---------------|------|------|
| Pectra Included | -- | EIP-6110 |
| Glamsterdam Declined | -- | EIP-6404 / EIP-6466 |
| Glamsterdam Considered | -- (1 maintained: EIP-2780) | -- |
| Fusaka Declined | -- (5 maintained: 5 EOF items) | -- |
| Dencun Included | -- (1 maintained: EIP-4844) | -- |

> The single-date diff looks small, but the daily toggle pattern was violent (5/11 EIP-4750/6110/6404/6466 returned + 6206 disappeared → 5/12 6110 disappeared again + 5920 appeared on both sides → 5/13 5450+5920 disappeared simultaneously + EOF 5 items → narrowed to 4 items → 5/14 5920/6466 both returned + 3-item window re-expanded). **Looking only at diffs between the two ends of each week captures less than 1/10 of the truncate-window deviation**. It must be read together with the daily toggle matrix (see daily briefing section) to be coherent.

### Trustworthy Changes (Calls / Commits / EF Blog 4-way Cross-verification)

---

## 3. Validator / Infrastructure Key Issues

### 5 Lido May 2026 Snapshots Proposed Simultaneously (5/13 11:10 UTC) -- Peak Governance Standardization Day

- **5 votes proposed in batch** ([Lido X main thread](https://x.com/LidoFinance/status/2054519728668897658)): (1) [NEST: Automated LDO Buyback and Liquidity Provisioning](https://x.com/LidoFinance/status/2054519731063779421) (Lido protocol revenue → automated LDO buyback + liquidity provisioning), (2) [Adopt the Node Operator Type Assessment Framework for CMv2](https://x.com/LidoFinance/status/2054519735270650038) (formal standardization of Curated Operator entry assessment criteria by DAO approval of the NO classification system for formal CMv2 entry), (3) [Transition from GateSeals to CircuitBreaker](https://x.com/LidoFinance/status/2054519739536322901) (temporary emergency halt renewed annually → institutional operational-risk simplification narrative through permanent contract standardization), (4) [Pier Two Participation in Curated Module and SDVT](https://x.com/LidoFinance/status/2054519743768338824) (MAVAN, formerly Pier Two, re-approved for Curated + SDVT), (5) [Increase Easy Track Transfer Limits for LOL to Align with EGG](https://x.com/LidoFinance/status/2054519747899777265).
- **May governance 7-day window**: 5/13 (proposal) → 5/18 16:00 UTC (batch close) → 5/21 14:00 UTC (alignment with Tokenholder Update Call result amplification). Core for Curated Operators: if (2) CMv2 NO Type Assessment Framework passes on 5/18, entry-material v2 drafting ETA 5/18~5/21 + integrate the (3) GateSeals → CircuitBreaker permanence narrative into entry materials.

### SSV Community NO ICS Framework Additional Scoring Proposal (5/13 14:06 UTC) -- DVT Permissionless-Entry Acceleration Track

- [Lido Research 11559](https://research.lido.fi/t/proposal-additions-to-the-lido-ics-framework-to-streamline-the-ssv-community-nos-path-to-verification/11559) (GBeast). Original quote: "Add a new score source: SSV pre-VO KYC to Proof of Humanity category [4 points] / Add a new score source: SSV High Signal score to Proof of Engagement [2 - 5 points]".
- Across the three stages ICS (Identified Community Staker) / VO (Verified Operator) / CSM (Community Staking Module), SSV community NOs obtain ICS eligibility faster through their own KYC bonus and operational reliability bonus. This leads to **Lido NO pool decentralization + lower dependence on permissioning + improved DVT operator ROI**.
- **First visibility of the Lido NO pool's triple-track governance structure**: (a) Curated Module v2 (permissioned + Type Assessment Framework standardization), (b) CSM-ICS (permissionless score accumulation + DVT acceleration), (c) SDVT (permissioned DVT) = new NO entrants can choose the track that matches their infrastructure/organizational structure.

### Existing A41 / SSV DVT Tracks + Remaining EarnETH Incident

- **Previous week's 5/7 A41 ~7,000 validator Exit case study** (Lido X 7-tweet campaign) entered full amplification stage this week = Curated Operator wind-down SOP 4.4x reduction (Organic 78 ETH → Scheduled/Batched 17.64 ETH) standardization material is now available for cumulative use in the weekly narrative.
- **SSV Network Anchor client Lido mainnet recommendation** (previous week 5/4) naturally aligns with this week's SSV Community NO ICS framework proposal = SSV track expands bidirectionally through **Curated Module + Simple DVT Module mainnet recommendation + permissionless CSM track acceleration**.
- **EarnETH Vault withdrawal halt, day 22 (as of 5/14, D+7 static)** -- freeze started 4/22 / "in the near future" (5/7 Lido X) ETA static at D+7 / entering the limit as the second week of May close (5/16) approaches / 5/15 (Fri) Lido content-cycle next-announcement candidate window + possible EarnETH ETA alignment (not disclosed at the time of this report).
- **Lido Tokenholder Update Call (5/21 14:00 UTC)** pre-announced at [Lido Research 11551](https://research.lido.fi/t/lido-tokenholder-update-call-may-21/11551) / lineup @_vshapovalov + @zuzu_eeka + @IsdrsP (Chief of Staking). It conflicts with ACDE #237 (90 minutes) in the same 14:00 UTC time slot, so monitoring the presentation order is key.
- **Credora @bvicentes stETH resilience amplification** (5/13 15:52 UTC) distributed via a Lido X Poolside Institutional full video the analysis that "stETH has superior resilience versus recent DeFi exploit waves through 1:1 algorithmic minting + industry-leading timelock protection." It pushed the institutional narrative and governance narrative simultaneously.

### EL Peer Composition Drift Week-2 Measurement -- Quantitative Exposure of Client Diversity Metric Limits

- [Stereum Labs 36-node fleet analysis](https://ethresear.ch/t/el-peer-composition-drifts-on-a-fixed-software-baseline-two-week-comparison-on-a-36-node-fleet/24857) (5/12 12:13 UTC, stefa2k). On the same EC/CC + same hardware + same Reth release baseline: (a) **Besu node Reth peer concentration ~75% → ~96%** (+21%p / week 2), (b) ~96% versus Reth network share of ~12% = **~8x asymmetric over-representation**, (c) Reth fleet connected peer ~123 → ~69 (-44%), (d) Reth fleet tracked peer table ~7,400 → ~2,506 (-66%).
- **Implication**: standard client diversity metrics (node-count ratio / clientdiversity.org) only partially reflect actual P2P topology safety, so peer-link-unit entropy measurement is needed. Besu operator P2P isolation risk arises at 96% Reth peer concentration. If a Reth client bug occurs, the Besu fleet could also be affected, partly neutralizing the original purpose of client diversity.
- It potentially aligns with the 5/20 P2P Networking #1 call agenda (Cell-level deltas + Sparse blobpool + Ethp2p), and could become a core follow-up discussion call.

### Continuing Client / Infrastructure Risks

- **EL/CL client release gap at day 45**: Geth v1.17.2 (CVE-26313/26314/26315 RPC + `debug_executionWitness` state corruption) + Lighthouse v8.1.3 (state root 10x regression + P2P security) **CRITICAL advisories unresolved for 45 days**. 5/5 Nethermind v1.37.2 (Breaking eth/66/67 drop) + 4/30 Reth v2.2.0 (Discv5 enabled by default) major changes remain cumulatively static.
- **200M Gas Limit Floor consensus + ePBS multi-client verification complete** means a ~3.3~5.6x increase versus current ~36M~60M. Curated Operators should set a 6~12 month ETA for CPU/RAM/NVMe SSD/network upgrades. If EIP-8261 (`gpo` fork pattern) activates, gas-limit decision authority is standardized from NOM governance into the ACD cycle.

| 5/13 (Wed) 15:00 UTC | L1-zkEVM Breakout | **#004** | EIP-8025 Prysm implementation update + 7 project presentations + zkVM input deserialization | Notes unpublished |
| 5/14 (Thu) 14:00 UTC | **ACDC — All Core Devs Consensus** | **#178** | **glam** + **hegotá** 2-item agenda / EIP-7805 FOCIL Hegotá CL Headliner reaffirmed / EIP-7716 / EIP-8205 candidate discussion | Notes unpublished |

**Note**: 4 calls on a single date, 5/13 (Wed), with 2 simultaneous starts at 14:00 UTC and 2 simultaneous starts at 15:00 UTC = peak listener fragmentation. **ACDE call absent** (next ACDE #237 is 5/21).

### Key Decision Summary

1. **ACDC #178 is the official starting point of the Glamsterdam → Hegotá transition.** The agenda structure itself was split into two items ("glam" + "hegotá"), and EIP-7805 FOCIL was effectively reaffirmed as the Hegotá CL headliner. EIP-7716 (Correlated Downtime Penalties, inclusion after PoC) + EIP-8205 (Validator Pre-registration, development in progress) Hegotá CL candidates were also discussed in earnest, resolving the 27-day ACDC non-registration critical path.

2. **ACDT #079 is the Glamsterdam devnet-1 + bal-devnet-7 confirmation stage.** It covered the Interop event (4/24~30) result summary, discussion of including EIP-8246 (Remove SELFDESTRUCT Burn) in the next devnet (follow-up to favorable ACDE #236 response), EIP-7928 BAL-devnet-7 v7.1.0, reflecting EIP-8037 PR #11616/#11611, REST SSZ EngineAPI Nethermind 5-10x performance improvement, and the proposal for the CL to determine the local gas limit (execution-apis #796). The EIP-8070 vs EIP-8136 dependency remains unresolved.

3. **Repricings #7 is the decision call for EIP-8037 spec freeze.** The agenda stated the phrase "Final decision" twice. The key items were a bal-devnet-7 (v7.1.0)-based single cost parameter, direct benchmarking of EIP-2780 TX_BASE_COST, and whether to include EIP-8038 in the devnet. Official notes are unpublished, but a 5-commit burst in the 13:39~16:26 UTC window (2 for 8037 + 2 for 8038 + 1 for 7851) is an alignment signal for the presumed merge of PR #11616 + #11611 and the spec-freeze result.

4. **Cumulative 14 unpublished official notes** (D+1 ~ D+57) -- ACDC #176 (D+57) / ACDE #233 (D+50) / ACDE #234 (D+36) / ACDC #177 (D+29) / ACDE #235 (D+22) / PQI #038 (D+9) / ACDE #236 (D+8) / ACDT #079 (D+4) / FCR #007 (D+3) / PQTS #008 (D+2) / Repricings #007 (D+2) / PQI #039 (D+2) / L1-zkEVM #004 (D+2) / ACDC #178 (D+1). **The key monitoring point is whether the official-note publication delay is resolved in batch during the 5/18 (ACDT #080) or 5/21 (ACDE #237) window**.

## 5. This Week's Recommended Topic Status + Priority Drafting Target Selection

### Daily Recommendations (Topic Recommender)

| Date | Recommendation 1 | Recommendation 2 | Score |
|------|-------|-------|------|
| 5/11 | **'Hegotá' new codename + ACDE #237 90-minute agenda** -- simultaneous decision call for two hard forks + deviation from city-name convention | **CFI in the Meta EIP body vs forkcast Considered** -- Glamsterdam governance-alignment structure through the EIP-7773 → EIP-8246 CFI case + The Purge SELFDESTRUCT cleanup track | 0.902 / 0.898 |
| 5/13 | **EIP-8261 (Gas Limit Schedule) 24h promotion** -- simultaneous removal of 4 tracks: validator preferred gas limit + EIP-1559 ±1/1024 + EL `--miner.gaslimit` + builder bids `gas_limit` | **36-node fleet 2-week P2P drift measurement** -- Besu→Reth ~75% → ~96% + blind spot in standard client-diversity metrics + peer-link entropy monitoring paradigm | 0.87 / 0.86 |
| 5/14 | **Lido May 2026 Snapshot 5 D-4** -- CMv2 NO Type Assessment Framework + GateSeals→CircuitBreaker + Pier Two/MAVAN re-approval + 5/18~5/21 7-day governance-peak window | **SSV Community NO ICS framework additional scoring** -- DVT operator ROI equation + first visibility of Lido NO pool triple-track (Curated v2 / CSM-ICS / SDVT) governance structure | **0.92 / 0.91** |

### Priority Drafting Targets (Top 3)

1. **[5/14 Recommendation 1, score 0.92] Lido May 2026 Snapshot 5 D-4 -- CMv2 NO Type Assessment Framework Standardization + GateSeals → CircuitBreaker Permanence** -- category: issue, length 4,500~5,500 characters.
   - **Reason**: (i) secures a solo insight window 4 days before the deadline in the concentrated 7-day governance window from 5/13 proposal → 5/18 16:00 UTC batch close → 5/21 14:00 UTC Tokenholder Call (0 external media analyses), (ii) if the CMv2 NO Type Assessment Framework passes, formal standardization of Curated Operator entry assessment criteria and entry-material v2 drafting ETA 5/18~5/21, (iii) GateSeals → CircuitBreaker permanence lets the institutional operational-risk simplification narrative be integrated into the package of 4 external attestations (StakingRewards A+ + Credora A+ + Bluechip A+ + Cantina Web3SOC) + 3 custody providers (BitGo + Fireblocks + Copper).
   - **Differentiation**: 0 Korean materials + 0 standalone English analyses after the 5/13 proposal + integrated narrative analysis of the May governance burst.

2. **[5/14 Recommendation 2, score 0.91] SSV Community NO ICS Framework Additional Scoring -- DVT Operator ROI Equation + First Visibility of Lido NO Pool Triple-Track Governance Structure** -- category: article, length 5,000~6,000 characters.
   - **Reason**: A solo insight window opened because there were 0 external responses/comments as of 2 days after GBeast posted Lido Research 11559 on 5/13 14:06 UTC. Formal listing of the accelerated Lido CSM/ICS entry track for DVT (SSV) operators is the first case where DVT infrastructure investment directly converts into Lido entry bonus points. Visualization of the Lido NO pool triple-track structure (Curated v2 / CSM-ICS / SDVT) is absent in both Korean and English.
   - **Differentiation**: Can be structured as a series with Recommendation 1 (Recommendation 1 is governance standardization, Recommendation 2 is the DVT permissionless-entry track; together they form the Lido NO pool triple structure).

3. **[5/11 Recommendation 1, score 0.902] 'Hegotá' New Codename + ACDE #237 (5/21, D-6) 90-minute Agenda** -- category: issue, length 4,500~5,500 characters.
   - **Reason**: The codename's **position (next hard fork) was formally confirmed** by the 5/12 EF blog phrase "Hegotá foundational work" and the 5/14 ACDC #178 "hegotá" agenda entry. The 5/21 ACDE #237 D-6 point maximizes advance-coordinate value and enables a follow-up comment note publication plan before/after the decision call. Deviation from city-name convention + AA track unification decision + Glamsterdam CFI/Considered candidate batch-decision scenario.
   - **Differentiation**: 0 Korean analyses + evaluation of the effect of AA track unification on Lido validators (key management and delegation structure).

> **Series Continuity Recommendation**: Build a serial series with Recommendation 1 (governance standardization) + Recommendation 2 (DVT permissionless-entry track), and explicitly link it to the 5/9 Lido EEA Treasury 5-way due-diligence package narrative to secure series continuity. The 5/18 Snapshot result + 5/21 Tokenholder Call result naturally align as v2 update windows for these recommended articles.

| 5/26 (Tue) | FCR — Fast Confirmation Rule | **#008** (estimated) | Client / Spec / Research / Testing updates |

### Devnet / Spec Milestones

- **Whether Glamsterdam devnet-1 launches immediately after 5/18 ACDT #080** -- bal-devnet-7 v7.1.0 + EIP-8037 Final Decision result reflected
- **bal-devnet-7 → bal-devnet-8 transition** -- whether EIP-8038 is included in the devnet + EIP-2780 TX_BASE_COST benchmarking result
- **Whether PQ Devnet-5 proceeds** -- PQI #039 (5/13) result undisclosed / awaiting conclusion on 3SF mini vs Goldfish

### Governance / Operations

- **5/18 16:00 UTC batch close of 5 Lido Snapshots** -- CMv2 NO Type Assessment Framework + GateSeals → CircuitBreaker + Pier Two/MAVAN re-approval + NEST LDO buyback + LOL Easy Track limit. If passed, entry-material v2 drafting ETA 5/18~5/21.
- **5/19 ERC-4337 possible Final point** -- Last Call 14-day window ends (previous week 5/5 → 5/19). Monitor PR #1640 merge timing.
- **5/21 14:00 UTC ACDE #237 + Lido Tokenholder Update Call simultaneous progress** -- same-time-slot conflict. Lido lineup @_vshapovalov + @zuzu_eeka + @IsdrsP (Chief of Staking) / four scenarios for "what's next" phrasing = (a) next institutional ETH treasury case, (b) new Curated Operator vacancy/rotation, (c) V3 stVaults progress, (d) NOM governance change.
- **EarnETH Vault freeze release ETA** -- "in the near future" D+8 (as of 5/15) / presumed limit for ETA disclosure before entering week 4 (5/19).

### Official Note Publication Delay Batch Resolution Monitoring

ACDC #176 (D+57) / ACDE #233 (D+50) / ACDE #234 (D+36) / ACDC #177 (D+29) / ACDE #235 (D+22) / PQI #038 (D+9) / ACDE #236 (D+8) / ACDT #079 (D+4) / FCR #007 (D+3) / PQTS #008 (D+2) / Repricings #007 (D+2) / PQI #039 (D+2) / L1-zkEVM #004 (D+2) / ACDC #178 (D+1) -- **possibility of batch publication immediately after the 5/18~5/21 call window**. Immediately read the full text of the Repricings #007 EIP-8037 Final Decision result + ACDC #178 Hegotá scoping consensus.

### Technical Risk Monitoring

- **Client release gap day 45 → entering the 50-day range** -- nodes with unresolved Geth v1.17.2 + Lighthouse v8.1.3 CRITICAL advisories need immediate patching or external RPC deactivation. After ACDT #080 (5/18), monitor GitHub Releases for EL/CL releases supporting Glamsterdam devnet-1 (EIP-8037/EIP-7928 BAL/EIP-8246 implementation tags).
- **EIP upgrade status (forkcast) data integrity LEVEL 3+ accumulated for 12 days** -- migration of `scripts/fetch_forkcast.py` to pagination or Trees API is delayed by 5 days / directly count actual file count in forkcast repo src/data/eips directory (hypothesis 300~500).
- **EL peer composition drift monitoring** -- Besu operators should immediately check `admin_peers` or metrics SOP / take peer-diversity measures if Reth peer ratio is 80%+. Monitoring the 5/20 P2P Networking #1 result is key.
