Struct CheckpointRfc 

pub struct CheckpointRfc {
    pub sequence: u64,
    pub checkpoint_id: Uuid,
    pub timestamp: u64,
    pub content_hash: [u8; 32],
    pub prev_hash: [u8; 32],

    pub chain_mac: Option<[u8; 32]>,
}

RFC-compliant checkpoint for CBOR wire format.

Separate from internal Checkpoint to allow different serialization strategies (JSON for human-readable, CBOR for wire).

Fields

sequence: u64

checkpoint_id: Uuid

timestamp: u64

content_hash: [u8; 32]

prev_hash: [u8; 32]

Zeros for the first checkpoint in a chain.

checkpoint_hash: [u8; 32]

vdf_proof: Option<VdfProofRfc>

jitter_binding: Option<JitterBinding>

chain_mac: Option<[u8; 32]>

Implementations

impl CheckpointRfc

pub fn new( sequence: u64, timestamp: u64, content_hash: [u8; 32], prev_hash: [u8; 32], ) -> Self

Create a checkpoint with a new UUID and zeroed checkpoint hash.

pub fn with_vdf(self, proof: VdfProofRfc) -> Self

Attach a VDF proof.

pub fn with_jitter(self, binding: JitterBinding) -> Self

Attach a jitter binding.

pub fn with_chain_mac(self, mac: [u8; 32]) -> Self

Attach a PUF-bound chain MAC.

pub fn compute_hash(&mut self)

Compute and set checkpoint_hash over all fields except itself.

pub fn validate(&self) -> Vec<String>

Validate all fields and return a list of errors (empty if valid).

pub fn is_valid(&self) -> bool

Return true if validate() produces no errors.
