How it fits together + +A Lean Ethereum node is two layers: **consensus** (ethlambda — ordering, fork +choice, attestations) and **execution** (ethrex — running transactions, +computing state). They interact every slot. + +``` +┌──────────────────────────────────────────┐ +│ ethlambda process │ +│ consensus layer │ +│ │ direct function calls │ +│ ethrex, embedded │ +│ (ethrex-blockchain / -storage / -common)│ +└──────────────────────────────────────────┘ +``` + +Three things cross the boundary, and that is the entire execution-layer surface: + +| Operation | When | ethrex call | +|---|---|---| +| `build_payload` | interval 4, when this node proposes next | `create_payload` + `Blockchain::build_payload` | +| `execute_payload` | on every block that arrives, and on our own | `Blockchain::add_block` | +| `set_head` | once per slot, at interval 0 | `apply_fork_choice` | + +The payload itself travels **inside the Lean block**: the proposer embeds an +`ExecutionPayloadV3` in the block body, and every peer executes it in its own +embedded ethrex. That is why the execution-payload schema lives in the consensus +types and the state transition, not in the engine crate. + +## 2. Prerequisites + +- Rust per `rust-toolchain.toml`. +- Docker, for the node image used by the devnet. +- A **Cancun** execution-layer genesis JSON (see [gotcha 2](#gotcha-2-the-el-genesis-must-be-cancun-not-prague)). +- An ethrex checkout is handy for reading APIs, but is not a build requirement — + ethrex is consumed as a pinned git dependency. + +## 3. Step-by-step + +### Step 1 — Depend on ethrex + +Three crates, pinned to one revision in `[workspace.dependencies]`: + +```toml +ethrex-common = { git = "https://github.com/lambdaclass/ethrex", rev = "…" } +ethrex-storage = { git = "https://github.com/lambdaclass/ethrex", rev = "…" } +ethrex-blockchain = { git = "https://github.com/lambdaclass/ethrex", rev = "…" } +``` + +> **Every ethrex crate in the workspace must share that revision.** `ethrex-crypto` +> bundles a C SHA3 whose symbols are not namespaced, so two ethrex versions in the +> graph produce `multiple definition of 'SHA3_absorb'` at link time under GNU `ld`. +> Audit for *pre-existing* ethrex dependencies — ours were hiding in the p2p crate +> for ENR parsing. See [gotcha 1](#gotcha-1-two-ethrex-versions-will-not-link). + +> **Do not depend on `ethrex-rpc`.** It has a ready-made payload↔block conversion, +> but unconditionally pulls in a full Axum server *and* `ethrex-p2p`, with no +> feature to slim it down. Step 3 reimplements the ~40-line mapping instead. + +Verify one ethrex in the graph, and let plain `cargo build` reconcile the +lockfile (`cargo update` can drag transitive crates past the pinned toolchain): + +```bash +grep -A2 'name = "ethrex-crypto"' Cargo.lock | grep -E 'version|rev=' | sort -u +``` + +### Step 2 — Bootstrap the engine + +`crates/net/ethrex-engine` wraps an ethrex `Store` + `Blockchain`: + +```rust +pub async fn from_genesis(genesis: Genesis) -> Result { + let mut store = Store::new("", EngineType::InMemory)?; + store.add_initial_state(genesis).await?; // async + let blockchain = Arc::new(Blockchain::default_with_store(store.clone())); + // … +} +``` + +The ethrex APIs used, all public library calls: + +| Purpose | API | Shape | +|---|---|---| +| Store | `Store::new(path, EngineType::InMemory)` | sync | +| Seed genesis | `store.add_initial_state(genesis)` | **async** | +| Engine | `Blockchain::default_with_store(store)` | sync | +| Head hash / number | `store.get_latest_canonical_block_hash()`, `get_latest_block_number()` | async | +| Payload skeleton | `create_payload(&args, &store, extra_data)` | 3 args → `Block` | +| Fill the payload | `blockchain.build_payload(block)` | **sync**, by value | +| Execute + persist | `blockchain.add_block(block)` | sync, by value | +| Fork choice | `apply_fork_choice(&store, head, safe, finalized)` | **async**, 3×H256 | + +### Step 3 — Convert payload ⇄ block + +`conversion.rs` maps between ethlambda's `ExecutionPayloadV3` and ethrex's +`Block`, mirroring ethrex-rpc's own `into_block`/`from_block` but against +`ethrex-common`. Most fields copy across; these do not: + +| Field | Handling | +|---|---| +| transactions | opaque SSZ bytes ⇄ typed txs via `Transaction::decode_canonical` / `encode_canonical_to_vec` | +| transactions_root, withdrawals_root | not in the payload — recompute with `compute_*_root(.., &NativeCrypto)` | +| base_fee_per_gas | `[u8; 32]` big-endian ⇄ ethrex `Option` (low 8 bytes) | +| logs_bloom | `[u8; 256]` ⇄ `Bloom` | +| fee_recipient | `[u8; 20]` ⇄ `Address` → header `coinbase` | +| ommers / difficulty / nonce | constants: `*DEFAULT_OMMERS_HASH`, empty, 0, 0 (post-merge) | +| parent_beacon_block_root | supplied by the caller — the Lean block's `parent_root` | +| requests_hash & friends | `None` — V3 predates them (gotcha 2) | + +### Step 4 — The engine API + +Deliberately *not* Engine-API shaped. 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.

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.

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.
