EIP-8025 Execution Proof Service //! -//! This service handles execution proof requests, signing and resigning workflows. +//! This service requests execution proofs, signs local completions, and submits them. //! -//! Three concurrent tasks: -//! 1. **Beacon event monitor**: subscribes to beacon node SSE for new blocks and -//! validated-proof events — requests proofs and resigns validated proofs. -//! 2. **Proof engine event monitor**: subscribes to proof engine SSE for proof -//! completion/failure events — fetches completed proofs, signs them, and -//! submits to the beacon node. -//! 3. **Reactive HTTP handler**: receives proofs from proof engine callbacks. +//! A single background task monitors beacon-node block events and proof-engine +//! completion/failure events. New blocks trigger proof requests; completed proofs +//! are fetched, signed, and submitted to the beacon node. use beacon_node_fallback::BeaconNodeFallback; -use bls::PublicKey; -use eth2::types::{BlockId, EventKind, EventTopic, SseExecutionProofValidated}; +use eth2::types::{BlockId, EventKind, EventTopic}; use execution_layer::NewPayloadRequest; use execution_layer::eip8025::types::ProofTypes; use execution_layer::eip8025::{HttpProofEngine, ProofEvent}; @@ -25,7 +20,7 @@ use std::time::{Duration, Instant}; use task_executor::TaskExecutor; use tracing::{debug, error, info, warn}; use types::execution::eip8025::{ProofAttributes, ProofData, PublicInput}; -use types::{Epoch, EthSpec, ExecutionProof, Hash256}; +use types::{EthSpec, ExecutionProof, Hash256}; use validator_store::{DoppelgangerStatus, ValidatorStore}; /// Discard tracking entries older than this. @@ -50,7 +45,6 @@ struct Inner { validator_store: Arc, beacon_nodes: Arc>, proof_engine: Arc, - slot_clock: T, executor: TaskExecutor, proof_types: Vec, /// Outstanding proof requests keyed by `new_payload_request_root`. @@ -63,7 +57,7 @@ impl ProofService, beacon_nodes: Arc>, proof_engine: Arc, - slot_clock: T, + _slot_clock: T, executor: TaskExecutor, proof_types: ProofTypes, ) -> Self { @@ -74,7 +68,6 @@ impl ProofService ProofService) -> Result<(), String> { let inner = self.inner.clone(); self.inner.executor.spawn( - async move { inner.monitor_events_task().await }, + async move { inner.monitor_task().await }, "proof_service_monitor", ); - let inner = self.inner.clone(); - self.inner.executor.spawn( - async move { inner.monitor_proof_engine_events_task().await }, - "proof_service_proof_engine_monitor", - ); - - info!("Proof service started - monitoring beacon events and proof engine events"); + info!("Proof service started - monitoring beacon and proof engine events"); Ok(()) } - - /// Public method called by HTTP API when proof engine callbacks with unsigned proof - /// - /// This is the reactive endpoint that receives proofs from the proof engine - /// and signs them with validator keys before submitting to beacon nodes. - pub async fn handle_proof_request( - &self, - pubkey: PublicKey, - execution_proof: ExecutionProof, - epoch: Option, - ) -> Result<(), String> { - self.inner - .sign_and_submit_proof(pubkey, execution_proof, epoch) - .await - } } impl Inner { - // ─── Beacon node event monitoring (existing) ──────────────────────── + // ─── Event monitoring ─────────────────────────────────────────────── - /// Subscribe to both `Block` and `ExecutionProofValidated` events via a single SSE stream. + /// Subscribe to `Block` events via SSE. async fn subscribe_to_events( &self, ) -> Result< @@ -127,26 +99,39 @@ impl Inner { String, > { self.beacon_nodes - .first_success(|node| async move { - node.get_events::(&[EventTopic::Block, EventTopic::ExecutionProofValidated]) - .await - }) + .first_success( + |node| async move { node.get_events::(&[EventTopic::Block]).await }, + ) .await .map_err(|e| format!("All beacon nodes failed to provide event stream: {}", e)) } - /// Monitor block and validated-proof events over a single SSE connection. - async fn monitor_events_task(self: Arc) { + /// Monitor beacon-node block events and proof-engine events over SSE. + async fn monitor_task(self: Arc) { info!("Starting proof service event monitoring via SSE"); loop { - match self.subscribe_to_events().await { - Ok(mut stream) => { - info!("Successfully subscribed to block and execution proof events"); + let mut beacon_stream = match self.subscribe_to_events().await { + Ok(stream) => { + info!("Successfully subscribed to block events"); + stream + } + Err(e) => { + error!(error = %e, "Failed to subscribe to block events, retrying..."); + tokio::time::sleep(Duration::from_secs(2)).await; + continue; + } + }; + let mut proof_stream = self.proof_engine.subscribe_proof_events(None); + let mut cleanup_interval = tokio::time::interval(PROOF_REQUEST_STALE_TIMEOUT); + cleanup_interval.set_missed_tick_behavior(tokio::time::MissedTickBehavior::Delay); + cleanup_interval.tick().await; - while let Some(event_result) = stream.next().await { + loop { + tokio::select!
