Struct RootAnchorEvidence 

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

Authenticated evidence that a generation root is committed by the store’s on-chain lineage.

Its fields are PRIVATE and exposed only through accessors: the only way to obtain a value is gather, which authenticates the launcher-coin anchor, the lineage, and the committing coin against the injected chain. A value witnesses that the root is genuinely anchored.

Implementations§

Source§

impl RootAnchorEvidence

Source

pub fn store_id(&self) -> Bytes32

The store’s launcher coin id (the unforgeable identity anchor this evidence chained to).

Source

pub fn generation_root(&self) -> Bytes32

The generation root proven to be committed on-chain by the store.

Source

pub fn committing_coin(&self) -> Bytes32

The lineage coin whose DataStore state committed generation_root.

Source

pub fn lineage_tip(&self) -> Bytes32

The store singleton’s current unspent tip at gather time.

impl Evidence for RootAnchorEvidence

Source§

fn gather<S: ChainSource>( claim: &Self::Claim, chain: &S, ) -> EvidenceResult<Self>

Gathers + authenticates the on-chain anchor for claim (see the module docs for the launcher-coin invariant). Fails closed on a missing/forged launcher, an absent lineage, an unreadable chain, or a root committed by no coin in the lineage.

Source§

fn verify(&self) -> EvidenceResult<()>

Re-asserts the anchor’s internal invariant OFFLINE: the evidence names a committing coin and its identity is anchored on the launcher coin (store_id). The chain-authenticated facts were established at gather time (the value cannot be forged), so an offline re-check without the chain confirms only self-coherence.
