Expand description

Minimum data needed to identify and verify an epoch checkpoint.

Binds network_id to the other fields to prevent cross-network replay.

Spec ref: SPEC §7.4 / VER-004.

Fields§

§network_id: Bytes32

Network identifier (prevents cross-network replay).

§epoch: u64

Epoch number this checkpoint summarizes.

§block_root: Bytes32

Ordered Merkle root over epoch block hashes (VER-001).

§state_root: Bytes32

Post-epoch L2 state root.

§withdrawals_root: Bytes32

Order-independent Merkle set root over epoch withdrawals (VER-003).

§checkpoint_hash: Bytes32

Hash of the underlying dig_block::Checkpoint struct.
