From 134dcb44c22bdf64d4bb6a850e3c9ddf36327909 Mon Sep 17 00:00:00 2001 From: Pablo Deymonnaz Date: Fri, 7 Aug 2026 19:40:52 -0300 Subject: [PATCH 1/2] feat: embed ethrex as the execution layer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Run the execution layer in-process: ethrex is linked in as a library and driven by direct function calls. One binary, no Engine API, no JSON-RPC, no JWT. New crate crates/net/ethrex-engine wraps an ethrex Store + Blockchain and exposes the whole execution-layer surface as three methods: build_payload(timestamp, prev_randao, beacon_root, fee_recipient) execute_payload(payload, parent_beacon_block_root) set_head(head, safe, finalized) The interface is deliberately not Engine-API shaped. In-process there is no latency to hide, so a payload is built and returned in one call: no payload id, no cache to hold it between calls, no build-then-fetch two-step. Only consensus types cross the boundary; ethrex's own types stay behind it. conversion.rs maps ExecutionPayloadV3 <-> ethrex Block against ethrex-common, so the heavyweight ethrex-rpc crate (Axum server + p2p stack) is not a dependency. Consensus side: - ExecutionPayloadV3 rides in the Lean block body, so peers execute the proposer's payload in their own embedded EL; the STF checks its parent hash and slot timestamp, and StateDiff carries the projected header so reconstructed states keep the EL block-hash chain. - The slot loop builds the payload inline at interval 4 (where the next block is already assembled), executes arriving payloads before the store sees the block, executes our own block's payload, and updates the EL head at interval 0. Every path is permissive: an EL failure logs and falls back to a synthetic payload rather than stalling consensus. - The consensus genesis is seeded with the EL genesis hash, read back from the engine itself rather than configured — its absence fails silently, leaving the EL frozen at genesis while consensus looks healthy. Every ethrex crate in the workspace is pinned to one revision, including the p2p crate's ENR helpers: ethrex-crypto bundles a C SHA3 with non-namespaced symbols, so two ethrex versions multiply-define them under GNU ld. macOS ld64 tolerates it, which is why this only surfaces in the Linux release build. --el-genesis is the entire EL surface; omit it for a consensus-only node. The genesis must be Cancun: a Prague genesis requires a requests_hash that the Cancun-shaped ExecutionPayloadV3 cannot carry. scripts/inprocess-devnet/run.sh runs a self-contained N-node devnet (no lean-quickstart checkout needed) and checks the log evidence; the guide is in docs/ethrex-inprocess-integration.md. Workspace builds, clippy -D warnings clean, fmt clean, 299 tests pass. --- .gitignore | 3 + Cargo.lock | 933 ++++-------------- Cargo.toml | 14 + bin/ethlambda/Cargo.toml | 1 + bin/ethlambda/src/checkpoint_sync.rs | 1 + bin/ethlambda/src/cli.rs | 8 + bin/ethlambda/src/main.rs | 77 +- crates/blockchain/Cargo.toml | 3 + crates/blockchain/src/aggregation.rs | 1 + crates/blockchain/src/block_builder.rs | 142 ++- crates/blockchain/src/el_integration.rs | 151 +++ crates/blockchain/src/lib.rs | 57 +- crates/blockchain/src/store.rs | 17 +- .../state_transition/src/execution_payload.rs | 194 ++++ crates/blockchain/state_transition/src/lib.rs | 12 + .../state_transition/tests/stf_spectests.rs | 20 + .../blockchain/tests/forkchoice_spectests.rs | 16 + .../blockchain/tests/signature_spectests.rs | 16 + crates/common/test-fixtures/src/common.rs | 2 + crates/common/test-fixtures/src/rejection.rs | 12 + crates/common/types/src/block.rs | 15 +- crates/common/types/src/el_genesis.rs | 64 ++ crates/common/types/src/execution_payload.rs | 614 ++++++++++++ crates/common/types/src/genesis.rs | 8 +- crates/common/types/src/lib.rs | 2 + crates/common/types/src/state.rs | 10 + crates/common/types/tests/ssz_spectests.rs | 13 +- crates/common/types/tests/ssz_types.rs | 6 + crates/net/ethrex-engine/Cargo.toml | 18 + crates/net/ethrex-engine/src/conversion.rs | 172 ++++ crates/net/ethrex-engine/src/lib.rs | 178 ++++ .../ethrex-engine/tests/fixtures/genesis.json | 202 ++++ crates/net/ethrex-engine/tests/roundtrip.rs | 84 ++ crates/net/p2p/Cargo.toml | 9 +- crates/net/p2p/src/lib.rs | 48 +- crates/net/rpc/src/lib.rs | 1 + crates/storage/src/state_diff.rs | 8 + docs/SUMMARY.md | 4 + docs/ethrex-inprocess-integration.md | 318 ++++++ docs/plans/ethrex-inprocess-poc.md | 163 +++ docs/plans/scope-down-to-inprocess.md | 157 +++ scripts/inprocess-devnet/README.md | 76 ++ scripts/inprocess-devnet/run.sh | 373 +++++++ 43 files changed, 3444 insertions(+), 779 deletions(-) create mode 100644 crates/blockchain/src/el_integration.rs create mode 100644 crates/blockchain/state_transition/src/execution_payload.rs create mode 100644 crates/common/types/src/el_genesis.rs create mode 100644 crates/common/types/src/execution_payload.rs create mode 100644 crates/net/ethrex-engine/Cargo.toml create mode 100644 crates/net/ethrex-engine/src/conversion.rs create mode 100644 crates/net/ethrex-engine/src/lib.rs create mode 100644 crates/net/ethrex-engine/tests/fixtures/genesis.json create mode 100644 crates/net/ethrex-engine/tests/roundtrip.rs create mode 100644 docs/ethrex-inprocess-integration.md create mode 100644 docs/plans/ethrex-inprocess-poc.md create mode 100644 docs/plans/scope-down-to-inprocess.md create mode 100644 scripts/inprocess-devnet/README.md create mode 100755 scripts/inprocess-devnet/run.sh diff --git a/.gitignore b/.gitignore index eb1f3df5..63bb853d 100644 --- a/.gitignore +++ b/.gitignore @@ -39,3 +39,6 @@ devnet.log # mdbook build output book/ + +# Standalone in-process devnet working directory (scripts/inprocess-devnet) +.devnet-inprocess/ diff --git a/Cargo.lock b/Cargo.lock index 47daf00b..28f7867e 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2,17 +2,6 @@ # It is not intended for manual editing. version = 4 -[[package]] -name = "addchain" -version = "0.2.1" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "2e33f6a175ec6a9e0aca777567f9ff7c3deefc255660df887e7fa3585e9801d8" -dependencies = [ -

Running in-process removes the reasons that +protocol is a stateless two-step exchange, so a payload is built and returned in +one call — no payload id, no server-side cache: + +```rust +pub async fn build_payload(&self, timestamp, prev_randao, beacon_root, fee_recipient) + -> Result; +pub fn execute_payload(&self, payload: &ExecutionPayloadV3, parent_beacon_block_root: H256) + -> Result<(), EngineError>; +pub async fn set_head(&self, head: H256, safe: H256, finalized: H256) + -> Result<(), EngineError>; +``` + +Consensus types cross the boundary (`ExecutionPayloadV3`, ethlambda's `H256`); +ethrex's own types stay behind it. + +### Step 5 — Seed the consensus genesis + +**Skip this and the execution layer is silently inert.** + +The Lean genesis block must carry the EL's genesis block hash, in the state's +cached header *and* in the genesis block body (`State::from_genesis_with_el_hash` +owns that protocol). Without it the first head update names a parent ethrex has +never seen, the EL declines to build, and every proposal quietly falls back to a +synthetic payload — consensus looks healthy while the EL does nothing. + +There is no flag for the hash: the engine bootstraps from `--el-genesis`, so its +startup head *is* the EL genesis block. Build the engine before state init and +read it back out: + +```rust +let engine = EthrexEngine::from_genesis_path(path).await?; +let el_genesis_hash = engine.head_hash().await?; // ← seeds the CL genesis +let store = fetch_initial_state(&urls, &cfg, backend, Some(el_genesis_hash)).await?; +``` + +### Step 6 — Wire it into the slot loop + +ethlambda assembles the *next* slot's block one interval early, at interval 4. +Because the embedded build is synchronous with no network latency, the payload is +built right there, inline: + +```rust +// SlotInterval::EndOfSlot +if let Some(validator_id) = next_proposer { + let execution_payload = self.build_execution_payload(next_slot).await; + self.propose_block(next_slot, validator_id, execution_payload).await; +} +``` + +The four hooks, all in `crates/blockchain/src/el_integration.rs`: + +| Hook | When | +|---|---| +| `notify_execution_layer` → `set_head` | interval 0, every slot (fire-and-forget) | +| `build_execution_payload` → `build_payload` | interval 4, only when proposing next | +| execute our own block's payload | after building — nobody gossips it back to us | +| `import_gossiped_block` → `execute_payload` | on arriving blocks, before the store sees them | + +Returning `None`/failing anywhere is safe: `build_block` falls back to +`synthetic_payload`, so a node with no EL — or a failing one — still produces +valid blocks. Consensus is never stalled by the execution layer. + +### Step 7 — CLI + +One flag. `--el-genesis ` enables the embedded EL; omitting it runs +ethlambda as a consensus-only node. + +### Step 8 — Tests + +`crates/net/ethrex-engine/tests/roundtrip.rs`: + +1. **`builds_executes_and_advances_head`** — build → execute → `set_head`, and the + EL's head advances to block 1. Exercises the conversion in both directions with + the EL judging its own output. +2. **`rejects_payload_with_mismatched_beacon_root`** — replaying a payload under a + different beacon root is rejected, since the root is committed to in the block + hash. + +Test 1 is what caught the Cancun/Prague problem before any devnet ran. + +```bash +cargo test -p ethlambda-ethrex-engine +cargo clippy --workspace --all-targets -- -D warnings +``` + +## 4. Running a devnet + +`scripts/inprocess-devnet/run.sh` spins up an N-node devnet where every node +embeds its own ethrex — no separate EL containers. It is self-contained: it +generates the validator keys, consensus genesis, ENRs and node keys itself, so it +needs only `docker` and `yq`. + +```bash +./scripts/inprocess-devnet/run.sh --build # 3 nodes, 20 slots +./scripts/inprocess-devnet/run.sh --nodes 1 --slots 10 # single node +./scripts/inprocess-devnet/run.sh --trace --keep # EL trace logs, stay up +``` + +See `scripts/inprocess-devnet/README.md` for the flags and the checks it runs. + +## 5. Verifying it works + +The EL hooks log at `trace!`, so a healthy run prints nothing about payload +builds at the default INFO level. Use `--trace` (which sets +`RUST_LOG=info,ethlambda_blockchain=trace`), then: + +```bash +# 1. did the embedded EL come up? (one line per node, identical hash) +grep -h "Embedded ethrex enabled" ethlambda_*.log + +# 2. is consensus advancing and finalizing? +grep -c "Block imported" ethlambda_1.log +grep -h "Checkpoint finalized" ethlambda_1.log | tail -1 + +# 3. is the EL building and executing? (needs --trace) +grep -hc "Built execution payload" ethlambda_*.log +grep -hc "EL executed payload" ethlambda_*.log + +# 4. red flags — all must be ZERO +grep -hc "using synthetic payload\|EL rejected payload" ethlambda_*.log +``` + +The load-bearing signal is that the EL **accepted** the payloads: that is its own +verdict after executing them against its state, not an acknowledgement of +receipt. Combined with zero synthetic fallbacks it means the embedded execution +layer really did the work. + +## 6. Gotchas + +### Gotcha 1: two ethrex versions will not link + +`ethrex-crypto` bundles a C SHA3 implementation whose symbols (`SHA3_absorb`, +`SHA3_squeeze`, …) are not namespaced. Two ethrex versions means two copies, and +GNU `ld` fails with `multiple definition`. **macOS `ld64` tolerates it**, so local +dev builds and `cargo test` pass while the Linux/Docker release build fails. +Unify every ethrex crate on one rev, and de-risk by linking the real binary on the +deployment platform. + +### Gotcha 2: the EL genesis must be Cancun, not Prague + +`ExecutionPayloadV3` is the Cancun shape. A Prague genesis (`pragueTime` set) +makes ethrex require a `requests_hash` in the header that a V3 payload cannot +carry, so execution rejects every block: + +``` +Invalid Block: Invalid Header, validation failed pre-execution: Requests hash is not present +``` + +Use `cancunTime: 0` with no `pragueTime`, and drop `prague` from `blobSchedule`. +Prague support means moving to `ExecutionPayloadV4` plus a `requests_hash`. + +### Gotcha 3: silence is not failure + +The EL hooks log at `trace!`. At INFO a perfectly healthy run prints nothing about +payload builds — indistinguishable from an EL that never ran. The dependable +INFO-level signal is the inverse: fallback and failure paths log at `warn!`, so +silence *there* means success. For positive proof, raise the log filter (§5). + +### Gotcha 4: a stale devnet harness looks like broken code + +An out-of-date test harness can produce a cascade of failures that look like bugs +in your change — unknown CLI flags, a genesis schema mismatch, missing config +fields. Update the harness first. This is why `scripts/inprocess-devnet/run.sh` +owns its inputs end to end. + +## 7. Design decisions + +| Decision | Rationale | +|---|---| +| A direct three-method API, not an Engine-API-shaped trait | With one implementation, the payload id, the payload cache and the build-then-fetch two-step are pure overhead — they exist only because the Engine API is stateless and networked. | +| Build the payload synchronously at interval 4 | No latency to hide in-process, so there is nothing to pre-request or stash across intervals, and no stale-head bookkeeping. | +| Reimplement the payload↔block conversion | ~40 lines of field mapping versus pulling in an Axum server and the p2p stack. | +| In-memory EL store | Simplest thing that proves the integration; EL state resets on restart. Persistence is an `ethrex-storage` feature away and pairs with EL-aware checkpoint sync. | +| Execution failure drops the block, never stalls consensus | An unexecutable payload means the block is pointless to import; anything else (no EL, internal error) is permissive and logged. | +| Derive the EL genesis hash instead of configuring it | The engine is the source of truth in-process, and the failure mode of forgetting it is silent. | +| No fee-recipient config | Lean has no fee market or block rewards yet, so there is nothing to direct. Add it when that changes. | + +## 8.

Implement `ExecutionEngine`: + - `forkchoice_updated_v3(state, None)` → `apply_fork_choice`, map result → `ForkChoiceUpdatedResponse` (payload_id = None). + - `forkchoice_updated_v3(state, Some(attrs))` → `apply_fork_choice`, build `BuildPayloadArgs` from attrs, compute `id()`, `create_payload`, stash `(id → Block)` in an internal map; return the id. + - `get_payload(id)` → look up the stashed block, `build_payload`, convert result `Block` → ethlambda `ExecutionPayloadV3`. + - `new_payload(payload, pbbr)` → ethlambda `ExecutionPayloadV3` → ethrex `Block` (`into_block`), `add_block`, map `Ok`→VALID / `Err`→INVALID → `PayloadStatus`. +4. **Type-conversion module** (the bulk of the code): ethlambda ⇄ ethrex for + `ExecutionPayloadV3`, `ForkChoiceState`, `PayloadAttributesV3`, `PayloadStatus`. + Both sides mirror `execution-apis` field-for-field, so it's mechanical but must be exact. + +### Phase 2 — CLI wiring (`bin/ethlambda/src/main.rs`) +1. `build_execution_client` currently returns the JSON-RPC `EngineClient`. Add a + mode selector: `--execution-mode {external,inprocess}` (default `external` to + preserve #367 behavior), plus `--el-genesis ` for the in-process store. +2. In `inprocess` mode, construct `EthrexEngine` and return it as `Arc`. + +### Phase 3 — Devnet validation +1. Extend/adapt `scripts/engine-api-demo/` (or the devnet-runner skill) to launch + ethlambda with `--execution-mode inprocess`; no separate ethrex process. +2. Confirm slot-by-slot advancement: proposal builds a real payload, import + executes it, EL head tracks the Lean head. Capture logs as the PoC evidence. + +### Phase 4 — Tests & docs +1.

Keeps an abstraction +with one implementor and a payload-id cache that exists only because the Engine +API is stateless.* + +**Option B — collapse to a direct in-process API. (recommended)** Drop the trait +and the wire types. `EthrexEngine` exposes what the actor actually needs: + +```rust +impl EthrexEngine { + /// Build the payload for `slot` on top of the current head. + pub async fn build_payload(&self, slot, timestamp, fee_recipient, beacon_root) + -> Result; + /// Execute and import a payload; Ok(()) means the EL accepted it. + pub async fn execute_payload(&self, payload: &ExecutionPayloadV3, parent_root: H256) + -> Result<(), EngineError>; + /// Point the EL at head / safe / finalized. + pub async fn set_head(&self, head: H256, safe: H256, finalized: H256) + -> Result<(), EngineError>; +} +``` + +*This deletes `PayloadId`, the `Mutex>` payload +cache, the `ForkChoiceUpdatedResponse`/`PayloadStatus` round-trip, and the whole +build-then-fetch two-step — all of which exist only because the Engine API is a +stateless request/response protocol. The actor holds +`Option>` instead of `Option>`.* +*Cost: if an external mode returns, the abstraction has to be reintroduced — but +#367 already has it, so it would come back with that PR.* + +### D2 — Does `--execution-mode` survive? + +With one mode, the flag is redundant. Proposal: **remove it**; the EL is enabled +by passing `--el-genesis ` and disabled by omitting it. One flag, no +invalid combinations. +*(Alternative: keep `--execution-mode inprocess` as the explicit opt-in. Say the +word if you prefer an explicit switch.)* + +### D3 — Branch strategy + +**Option A — removal commits on the current branch (recommended).** Add commits +that delete the Engine-API code. The **diff against main**, which is what +reviewers read, ends up exactly right. History shows add-then-remove, which a +squash-merge flattens. + +**Option B — fresh branch off main, re-apply only the in-process work.** Clean +history and clean diff, at the cost of redoing the merge with a fast-moving main +(14 commits in the last two hours) and losing this branch's commit trail. + +### D4 — Keep the mock-EL test seam? + +`ExecutionEngine` also let tests substitute a mock EL. Under Option B there is no +trait to mock. The `ethrex-engine` integration tests already drive a real embedded +ethrex, which is arguably better coverage. Flagging it so the loss is deliberate. + +## 4. Execution steps (assumes D1=B, D2=remove, D3=A) + +1. **Move the payload types out of the doomed crate.** `ExecutionPayloadV3` and + friends already live in `ethlambda-types`; confirm nothing else in + `ethrex-client` is load-bearing. +2. **Rewrite `EthrexEngine`'s public API** to the three methods above; delete the + payload-id cache and the `ExecutionEngine` impl. Update + `crates/net/ethrex-engine/tests/roundtrip.rs` to the new API. +3. **Rewrite `el_integration.rs`** against the new API: `build_execution_payload` + becomes one call; `validate_payload_with_el` calls `execute_payload`; + `notify_execution_layer` calls `set_head`. Keep the permissive posture — an EL + error logs and never stalls consensus. +4. **Change the actor's field** to `Option>` (`lib.rs`, + `BlockChainConfig`). +5. **Strip the CLI**: delete the four external flags and `ExecutionMode`; keep + `--el-genesis`; `build_inprocess_engine` becomes the only constructor. +6. **Delete** `crates/net/ethrex-client/` entirely, its workspace member entry and + dependency lines, plus `reqwest`/`jsonwebtoken` if nothing else uses them. +7. **Delete** `scripts/engine-api-demo/` and the two #367 plan docs. +8. **Update the docs** — `docs/ethrex-inprocess-integration.md` currently frames + everything as "second implementation of the trait"; rewrite sections 1, 2, 4 + and the design-decisions table around the direct API.

A consensus-only control run on the same image finalized normally, isolating the fault to the integration. The state transition requires payload.parent_hash == state.latest_execution_payload_header.block_hash which is the parent the consensus chain expects. build_payload instead derived it from store.get_latest_canonical_block_hash(), the node's *own* EL head. Each node runs an independent in-memory execution layer, so those two drift apart, and a proposer's payload then named a parent no peer agreed with — every node's STF rejected the block. It failed silently from the proposer's side: no EL rejection, no warning, the block just never stuck. The Engine-API path did not have this bug, because its build-mode forkchoiceUpdated pointed the EL at el_hash_at(store.head()) before building. Collapsing that two-step into a single call dropped the step that chose the parent. build_payload now takes parent_el_hash explicitly and re-points the EL at that block before building; el_integration passes el_hash_at(head_root). safe and finalized are left unset in that fork-choice call, since pinning them would forbid a later build on an earlier block. Regression test builds_on_the_requested_parent_not_the_el_head advances the EL two blocks, then builds on block 1 and asserts the payload names that parent; it fails against the previous code. Unit tests could not have caught this — it needs more than one execution layer to appear. Verified: 3 nodes, 36 slots, finalized at slot 40 with all nodes on the same finalized root and 43 payloads executed each; zero parent_hash mismatches, zero synthetic fallbacks, zero panics. Matches the consensus-only control (slot 41). --- crates/blockchain/src/el_integration.rs | 7 + crates/net/ethrex-engine/src/lib.rs | 29 ++- crates/net/ethrex-engine/tests/roundtrip.rs | 58 ++++++ docs/plans/scope-down-review.md | 195 ++++++++++++++++++++ scripts/inprocess-devnet/run.sh | 17 +- 5 files changed, 293 insertions(+), 13 deletions(-) create mode 100644 docs/plans/scope-down-review.md diff --git a/crates/blockchain/src/el_integration.rs b/crates/blockchain/src/el_integration.rs index e70302e1..1f2ab0aa 100644 --- a/crates/blockchain/src/el_integration.rs +++ b/crates/blockchain/src/el_integration.rs @@ -85,8 +85,15 @@ impl BlockChainServer { let engine = self.execution_engine.as_ref()?; let head_root = self.store.head().unwrap_or_default(); let genesis_time = self.store.config().genesis_time; + // Build on the EL block the *consensus* chain expects to be extended — + // the head block's own payload hash — not whatever this node's EL happens + // to have as its head.

Decisions to scrutinise + +Each is reversible; the cost of reversing is noted. + +**1. Direct API instead of the `ExecutionEngine` trait.** (your D1=B) +`build_payload` / `execute_payload` / `set_head`. This deleted `PayloadId`, the +`Mutex>` payload cache, and the build-then-fetch two-step — +all artefacts of the Engine API being stateless and networked. +*Reversing:* reintroduce the trait, which #367 already contains. + +**2. No fee-recipient configuration.** ← *the one I am least sure about* +#367 read `suggested_fee_recipient` from `validator-config.yaml`; main has no such +plumbing. Rather than re-add config parsing for something the integration does not +need, the EL is handed the zero address with a comment. Lean has no fee market or +block rewards, so nothing is being directed anywhere. +*Reversing:* ~20 lines — a config field, a hex parser, and one more `BlockChainConfig` field. + +**3. The EL genesis hash is derived, not configured.** +The engine bootstraps from `--el-genesis`, so its startup head *is* the EL genesis +block; `main.rs` reads it back and seeds the consensus anchor. The external path +needed a flag because the EL was a separate process. +*Why it matters:* forgetting this seed fails **silently** — consensus looks healthy +while the EL sits frozen at genesis and every proposal falls back to a synthetic +payload. Worth confirming you find the derivation trustworthy. + +**4. `execute_payload` is synchronous.** +`Blockchain::add_block` is a sync ethrex call, so the gossip-import path no longer +awaits. Simpler, but it does mean EL execution happens on the actor thread. +*Consider:* whether block execution time on the actor is acceptable, or whether it +should move off-thread later. + +**5. Single ethrex revision across the workspace.** +`crates/net/p2p` was pinned to an older ethrex for ENR parsing; it now follows the +workspace revision, which required porting `parse_enrs` to v15's typed +`NodeRecord`. This touches a crate unrelated to the feature. +*Why it is not optional:* `ethrex-crypto` bundles a C SHA3 with non-namespaced +symbols, so two ethrex versions multiply-define them under GNU `ld`. macOS `ld64` +tolerates it — it only fails in the Linux release build. + +**6. In-memory EL store.** EL state resets on restart. Fine for a PoC; persistence +is an `ethrex-storage` feature away and pairs with EL-aware checkpoint sync. + +**7. Mock-EL test seam dropped.** (your D4) No trait means nothing to mock; the +engine tests drive a real embedded ethrex instead. + +## 5. Consensus-path changes to check carefully + +These touch the tick loop, so they deserve more attention than the rest: + +- **Interval 4** — `build_execution_payload` runs inline, immediately before the + block is assembled. Failure returns `None` and `build_block` falls back to + `synthetic_payload`. +- **Interval 0** — `notify_execution_layer` updates the EL head, spawned + fire-and-forget. +- **Gossip import** — `import_gossiped_block` executes the payload *before* the + store sees the block. A rejection drops the block; anything else proceeds. +- **Own block** — after building, we execute our own payload, because nobody + gossips it back to us and the EL head would otherwise never advance. + +The invariant throughout: **the execution layer never stalls consensus.** Only an +explicit rejection of a received payload drops a block; every other failure logs +and continues. + +## 6. Verification status + +| Check | Status | +|---|---| +| `cargo build --workspace` | ✅ clean | +| `cargo clippy --workspace --all-targets -- -D warnings` | ✅ clean | +| `cargo fmt --all --check` | ✅ clean | +| Tests (blockchain, state-transition, engine, bin, p2p) | ✅ **299 passed, 0 failed** | +| Engine roundtrip + beacon-root rejection tests | ✅ pass | +| 3-node devnet **with** the embedded EL | ✅ finalized at slot 40 | +| 3-node devnet **without** the EL (control) | ✅ finalized at slot 41 | + +The EL-enabled run matches the consensus-only control, so the execution layer +costs nothing in liveness. All three nodes agreed on the same finalized root, and +each executed exactly 43 payloads — lockstep. + +### 6.1 Bug found by the devnet and fixed: `parent_hash mismatch` + +Worth reading, because it is the one real defect the scope-down introduced and no +unit test could have caught it — it only appears with **multiple independent +execution layers**. + +**Symptom.** With the EL enabled the chain never finalized: 22 `parent_hash +mismatch` errors, peer imports halved (13 vs 30), no aggregation coverage, no +finality. Silent from the proposer's side — zero EL rejections, zero warnings. +The block simply did not stick anywhere. + +**Cause.** The state transition requires + +``` +payload.parent_hash == state.latest_execution_payload_header.block_hash +``` + +— the parent the *consensus chain* expects. `build_payload` instead derived the +parent from `store.get_latest_canonical_block_hash()`, this node's *own* EL head. +With three independent ELs those drift apart, so a proposer's payload named the +wrong parent and every node's STF rejected the block. + +#367 did not have this bug: its build-mode `forkchoiceUpdated` pointed the EL at +`el_hash_at(store.head())` before building. Collapsing that two-step into one call +dropped the step that set the parent. + +**Fix.** `build_payload` takes `parent_el_hash` explicitly; `el_integration` passes +`el_hash_at(head_root)` — the consensus head's payload hash — and the engine +re-points the EL at that block before building. safe/finalized are deliberately +left unset there: pinning them would forbid a later build on an earlier block. + +**Regression test.** `builds_on_the_requested_parent_not_the_el_head` advances the +EL two blocks, then asks for a payload extending block 1 and asserts the payload +names *that* parent. It fails against the old code. + +**Method note.** The first hypothesis — that `import_gossiped_block` was dropping +blocks on EL rejection — was wrong, and the logs disproved it (zero rejections) +before any code was changed. + +## 7. Open questions for you + +1. **Publishing.** Force-push this onto `feat/ethrex-inprocess-poc` (keeps PR #530 + and its discussion) or push `feat/ethrex-inprocess` as a new PR and close #530? + Force-push rewrites the remote branch, so it needs your say-so. +2. **Decision 2** — fee-recipient config: leave dropped, or restore it? +3. **Decision 4** — EL execution on the actor thread: acceptable for now? +4.
