This caused a state desynchronization where components like the transaction pool would operate on a stale, more advanced block state. This could lead to errors, such as "nonce too low", when validating new transactions against the incorrect (post-reorg) state. This commit introduces the `update_latest_block_to_canonical_ancestor` method, which is now called during FCU processing.

This was insufficient for handling reorgs where the new head is an ancestor of the current head (an unwind). This discrepancy could lead to a stale in-memory state. When the state provider attempted to access account information, it would fall back to the stale database state, causing transaction validation failures such as "nonce too low" errors. This commit refactors the logic to correctly handle unwinds. It now detects when the new head number is lower than the current one and treats it as a reorg. It collects the now-invalid blocks from the in-memory state and updates the chain by removing them and loading the new canonical ancestor. This ensures the in-memory state accurately reflects the canonical chain after a reorg. --- crates/engine/tree/src/tree/mod.rs | 192 ++++++++++++++++++++++++----- 1 file changed, 162 insertions(+), 30 deletions(-) diff --git a/crates/engine/tree/src/tree/mod.rs b/crates/engine/tree/src/tree/mod.rs index de23e0bf8c0..1f44a036024 100644 --- a/crates/engine/tree/src/tree/mod.rs +++ b/crates/engine/tree/src/tree/mod.rs @@ -720,10 +720,29 @@ where let new_head_number = canonical_header.number(); let new_head_hash = canonical_header.hash(); - // Detect and log the type of chain state update + // Log the type of chain state update being performed + self.log_chain_update_type(current_head_number, new_head_number, new_head_hash); + + // Update tree state with the new canonical head + self.state.tree_state.set_canonical_head(canonical_header.num_hash()); + + // Handle the state update based on whether this is an unwind scenario + if new_head_number < current_head_number { + self.handle_chain_unwind(current_head_number, canonical_header) + } else { + self.handle_chain_advance_or_same_height(canonical_header) + } + } + + /// Logs the type of chain state update being performed. + fn log_chain_update_type( + &self, + current_head_number: u64, + new_head_number: u64, + new_head_hash: B256, + ) { match new_head_number.cmp(¤t_head_number) { std::cmp::Ordering::Less => { - // Unwind scenario: we're reverting to an earlier canonical block debug!( target: "engine::tree", current_head = current_head_number, @@ -733,7 +752,6 @@ where ); } std::cmp::Ordering::Greater => { - // Forward progress: updating to a later canonical block debug!( target: "engine::tree", previous_head = current_head_number, @@ -743,7 +761,6 @@ where ); } std::cmp::Ordering::Equal => { - // Same block number, potentially different hash (shouldn't normally happen) debug!( target: "engine::tree", head_number = new_head_number, @@ -752,38 +769,153 @@ where ); } } + } - // Update tree state - self.state.tree_state.set_canonical_head(canonical_header.num_hash()); + /// Handles chain unwind scenarios by collecting blocks to remove and performing a reorg. + fn handle_chain_unwind( + &mut self, + current_head_number: u64, + canonical_header: &SealedHeader, + ) -> ProviderResult<()> { + let new_head_number = canonical_header.number(); + let new_head_hash = canonical_header.hash(); - // CRITICAL: Load the canonical ancestor's block into memory to ensure - // state provider can access it.
