Struct EngineSyncState

Source 
pub struct EngineSyncState { /* private fields */ }
Expand description

The synchronization state of the execution layer across different safety levels.

Tracks block progression through various stages of verification and finalization, from initial unsafe blocks received via P2P to fully finalized blocks derived from finalized L1 data. Each level represents increasing confidence in the block’s validity.

§Safety Levels

The state tracks blocks at different safety levels, listed from least to most safe:

  1. Unsafe - Most recent blocks from P2P network (unverified)
  2. Cross-unsafe - Unsafe blocks with cross-layer verification
  3. Local-safe - Derived from L1 data, completed span-batch
  4. Safe - Cross-verified with safe L1 dependencies
  5. Finalized - Derived from finalized L1 data only

See the OP Stack specifications for detailed safety definitions.

Implementations§

Source§

impl EngineSyncState

Source

pub const fn unsafe_head(&self) -> L2BlockInfo

Returns the current unsafe head.

Source

pub const fn cross_unsafe_head(&self) -> L2BlockInfo

Returns the current cross-verified unsafe head.

Source

pub const fn local_safe_head(&self) -> L2BlockInfo

Returns the current local safe head.

Source

pub const fn safe_head(&self) -> L2BlockInfo

Returns the current safe head.

Source

pub const fn finalized_head(&self) -> L2BlockInfo

Returns the current finalized head.

Source

pub const fn create_forkchoice_state(&self) -> ForkchoiceState

Creates a ForkchoiceState

  • head_block = unsafe_head
  • safe_block = safe_head
  • finalized_block = finalized_head

If the block info is not yet available, the default values are used.

Source

pub fn apply_update(self, sync_state_update: EngineSyncStateUpdate) -> Self

Applies the update to the provided sync state, using the current state values if the update is not specified. Returns the new sync state.
