The genesis state has no envelope so it must always be Pending. The Gloas upgrade sets latest_execution_payload_bid.block_hash == latest_block_hash causing is_parent_block_full() to return true incorrectly. - Fix fork choice anchor initialization for Gloas genesis. The genesis block has a default (zeroed) bid, so execution_payload_block_hash was set to 0x0 in the anchor node. This caused child blocks to be placed on the Empty path instead of Full, preventing fork choice from advancing the head. Use latest_block_hash from the anchor state when the block bid hash is zero. - Recompute head after envelope processing in add_block_at_slot. Gloas fork choice requires payload_received=true before selecting a block as head, so the head must be recomputed after the envelope. --- beacon_node/beacon_chain/src/test_utils.rs | 3 +++ consensus/fork_choice/src/fork_choice.rs | 12 +++++++++++- consensus/types/src/state/beacon_state.rs | 3 +++ 3 files changed, 17 insertions(+), 1 deletion(-) diff --git a/beacon_node/beacon_chain/src/test_utils.rs b/beacon_node/beacon_chain/src/test_utils.rs index 386c5c24f62..ac96162755c 100644 --- a/beacon_node/beacon_chain/src/test_utils.rs +++ b/beacon_node/beacon_chain/src/test_utils.rs @@ -3000,6 +3000,9 @@ where if let Some(envelope) = opt_envelope { self.process_envelope(block_hash.into(), envelope, &mut new_state) .await; + // Recompute head after processing the envelope: Gloas fork choice requires the + // payload envelope to be present before selecting a block as head. + self.chain.recompute_head_at_current_slot().await; } Ok((block_hash, block_contents, new_state)) } diff --git a/consensus/fork_choice/src/fork_choice.rs b/consensus/fork_choice/src/fork_choice.rs index 92fd4c1faf3..6cb931d9bee 100644 --- a/consensus/fork_choice/src/fork_choice.rs +++ b/consensus/fork_choice/src/fork_choice.rs @@ -417,10 +417,20 @@ where if let Ok(signed_bid) = anchor_block.message().body().signed_execution_payload_bid() { // Gloas: execution status is irrelevant post-Gloas; payload validation // is decoupled from beacon blocks. + // For the genesis anchor, the block's bid is default (zeroed), so use + // latest_block_hash from the state which reflects the actual EL genesis hash. + let block_hash = if signed_bid.message.block_hash.into_root().is_zero() { + (*anchor_state + .latest_block_hash() + .map_err(Error::BeaconStateError)?) + .into() + } else { + signed_bid.message.block_hash + }; ( ExecutionStatus::irrelevant(), Some(signed_bid.message.parent_block_hash), - Some(signed_bid.message.block_hash), + Some(block_hash), ) } else if let Ok(execution_payload) = anchor_block.message().execution_payload() { // Pre-Gloas forks: do not set payload hashes, they are only used post-Gloas. diff --git a/consensus/types/src/state/beacon_state.rs b/consensus/types/src/state/beacon_state.rs index a033272b9d9..68436ed2bce 100644 --- a/consensus/types/src/state/beacon_state.rs +++ b/consensus/types/src/state/beacon_state.rs @@ -1284,6 +1284,9 @@ impl BeaconState { pub fn payload_status(&self) -> StatePayloadStatus { if !self.fork_name_unchecked().gloas_enabled() { StatePayloadStatus::Pending + } else if self.slot() == 0 { + // The genesis state is always Pending: there is no genesis envelope. + StatePayloadStatus::Pending } else if self.is_parent_block_full() { StatePayloadStatus::Full } else { From cb10414b94d67c772c99a9590bdc79bcb6d3dc46 Mon Sep 17 00:00:00 2001 From: Michael Sproul Date: Tue, 7 Apr 2026 12:15:33 +1000 Subject: [PATCH 027/122] Fix comments --- beacon_node/beacon_chain/src/canonical_head.rs | 1 - beacon_node/beacon_chain/src/summaries_dag.rs | 2 +- 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/beacon_node/beacon_chain/src/canonical_head.rs b/beacon_node/beacon_chain/src/canonical_head.rs index 274ef8c21fc..8664afdb59b 100644 --- a/beacon_node/beacon_chain/src/canonical_head.rs +++ b/beacon_node/beacon_chain/src/canonical_head.rs @@ -974,7 +974,6 @@ impl BeaconChain { // The store migration task and op pool pruning require the *state at the first slot of the // finalized epoch*, rather than the state of the latest finalized block.

Execution requests from a payload envelope are now deferred and processed during the next block's state transition via process_parent_execution_payload, eliminating the dual post-state (Pending/Full) per block root. Key changes: - New process_parent_execution_payload in per_block_processing - Refactor process_execution_payload_envelope to verify_execution_payload (pure verification, no state mutation) - Add execution_requests_root to ExecutionPayloadBid - Add parent_execution_requests to BeaconBlockBody (Gloas) - Remove state_root from ExecutionPayloadEnvelope - Update Gloas withdrawals guard condition Co-Authored-By: Claude Opus 4.6 --- .../state_processing/src/block_replayer.rs | 22 +-- .../src/envelope_processing.rs | 155 +++++------------- .../src/per_block_processing.rs | 94 +++++++++++ .../src/per_block_processing/errors.rs | 5 + .../src/per_block_processing/withdrawals.rs | 4 +- .../state_processing/src/upgrade/gloas.rs | 5 +- consensus/types/src/block/beacon_block.rs | 1 + .../types/src/block/beacon_block_body.rs | 6 + .../src/execution/execution_payload_bid.rs | 1 + .../execution/execution_payload_envelope.rs | 2 - 10 files changed, 162 insertions(+), 133 deletions(-) diff --git a/consensus/state_processing/src/block_replayer.rs b/consensus/state_processing/src/block_replayer.rs index 04650606b65..333ff79173d 100644 --- a/consensus/state_processing/src/block_replayer.rs +++ b/consensus/state_processing/src/block_replayer.rs @@ -1,9 +1,7 @@ use crate::{ BlockProcessingError, BlockSignatureStrategy, ConsensusContext, SlotProcessingError, VerifyBlockRoot, VerifySignatures, - envelope_processing::{ - EnvelopeProcessingError, VerifyStateRoot, process_execution_payload_envelope, - }, + envelope_processing::{EnvelopeProcessingError, verify_execution_payload}, per_block_processing, per_epoch_processing::EpochProcessingSummary, per_slot_processing, @@ -250,36 +248,34 @@ where Ok(state_root) } - /// Apply an execution payload envelope to `self.state`. + /// Verify an execution payload envelope against `self.state`. /// /// The `block_state_root` MUST be the `state_root` of the most recently applied block. /// - /// Returns the `state_root` of `self.state` after payload application. + /// Since `verify_execution_payload` performs no state mutation, the state root remains + /// unchanged (equal to `block_state_root`). fn apply_payload_envelope( &mut self, envelope: &SignedExecutionPayloadEnvelope, block_state_root: Hash256, ) -> Result { - // TODO(gloas): bulk signature verification could be relevant here? let verify_payload_signatures = if let BlockSignatureStrategy::NoVerification = self.block_sig_strategy { VerifySignatures::False } else { VerifySignatures::True }; - // TODO(gloas): state root verif enabled during initial prototyping - let verify_state_root = VerifyStateRoot::True; - process_execution_payload_envelope( - &mut self.state, - Some(block_state_root), + verify_execution_payload( + &self.state, envelope, verify_payload_signatures, - verify_state_root, + Some(block_state_root), self.spec, ) .map_err(BlockReplayError::from)?; - Ok(envelope.message.state_root) + // No state mutation - the state root is unchanged from the post-block root. + Ok(block_state_root) } /// Apply `blocks` atop `self.state`, taking care of slot processing. diff --git a/consensus/state_processing/src/envelope_processing.rs b/consensus/state_processing/src/envelope_processing.rs index 97953b835f6..1eef112dfa1 100644 --- a/consensus/state_processing/src/envelope_processing.rs +++ b/consensus/state_processing/src/envelope_processing.rs @@ -1,15 +1,10 @@ -use crate::BlockProcessingError; use crate::VerifySignatures; use crate::per_block_processing::compute_timestamp_at_slot; -use crate::per_block_processing::process_operations::{ - process_consolidation_requests, process_deposit_requests_post_gloas, - process_withdrawal_requests, -}; -use safe_arith::{ArithError, SafeArith}; +use safe_arith::ArithError; use tree_hash::TreeHash; use types::{ - BeaconState, BeaconStateError, BuilderIndex, BuilderPendingPayment, ChainSpec, EthSpec, - ExecutionBlockHash, Hash256, SignedExecutionPayloadEnvelope, Slot, + BeaconState, BeaconStateError, BuilderIndex, ChainSpec, EthSpec, ExecutionBlockHash, Hash256, + SignedExecutionPayloadEnvelope, Slot, }; macro_rules! envelope_verify { @@ -20,29 +15,11 @@ macro_rules! envelope_verify { }; } -/// The strategy to be used when validating the payloads state root. -#[cfg_attr(feature = "arbitrary", derive(arbitrary::Arbitrary))] -#[derive(PartialEq, Clone, Copy)] -pub enum VerifyStateRoot { - /// Validate state root. - True, - /// Do not validate state root.
