Enum CheckpointStatus 

Source 
pub enum CheckpointStatus {
    Pending,
    Collecting,
    WinnerSelected {
        winner_hash: Bytes32,
        winner_score: u64,
    },

Expand description

L2 checkpoint epoch lifecycle (SPEC §2.8, CKP-003).

Variants: Three unit variants (Pending, Collecting, Failed) and two struct variants that pin the winning checkpoint hash (winner_hash) — first with off-chain winner_score, then with on-chain l1_height after L1 inclusion.

Variants§

§

Pending

Epoch has not yet started checkpoint collection.

§

Collecting

Validators are submitting checkpoint proposals for the epoch.

§

WinnerSelected

Winning checkpoint chosen off-chain / in L2 consensus; not yet L1-confirmed.

Fields

§winner_hash: Bytes32

Identity (hash) of the winning checkpoint proposal.

§winner_score: u64

Score used for comparison during winner selection (CKP-004 will define computation).

§

Finalized

Winning checkpoint confirmed on L1 at l1_height.

Fields

§winner_hash: Bytes32

Same logical winner as in Self::WinnerSelected once finalized.

§l1_height: u32

L1 block height at which inclusion was observed.

§

Failed

Epoch checkpointing failed (e.g. insufficient participation).
