StoreOwnershipProof

dig_identity::pairing

Struct StoreOwnershipProof 

Source 
pub struct StoreOwnershipProof {
    pub singleton: IdentitySingleton,
    pub store: StoreRecord,
}
Expand description

A convenience bundle of the (singleton, store) records the pairing predicate runs over.

NOT a self-authenticating, trustless proof. StoreOwnershipProof::verify re-runs the section 7 predicate – it confirms the discovery link (store.description == did:chia:<launcher_id>) AND the authority link (store.launcher_coin.parent_coin_info is a member of singleton.lineage) – but that decision is SOUND ONLY RELATIVE TO a singleton.lineage the verifier has INDEPENDENTLY resolved on-chain (WU3) as did.launcher_id’s authentic singleton lineage.

Both singleton.did and singleton.lineage are independent, caller-supplied fields with NO internal binding: nothing here checks that lineage is the DID’s real singleton lineage. A producer may therefore supply ANY lineage – e.g. their own singleton’s – so a store they launched themselves passes verify() against a victim’s DID. Consuming this bundle from an UNTRUSTED producer is a spoofing trap: verify() == true means only “these two records satisfy the predicate”, not “this store is chain-authenticated as the DID’s profile”.

The trustworthy portable proof – one whose lineage is chain-bound to the DID – is WU3’s job. Use this type only when YOU have resolved singleton.lineage on-chain yourself.

Fields§

§singleton: IdentitySingleton

The identity singleton the store claims to belong to. lineage MUST be the verifier’s own on-chain-resolved singleton lineage for did (WU3) – it is NOT authenticated by Self::verify.

§store: StoreRecord

The candidate profile store record.

Implementations§

Source§

impl StoreOwnershipProof

Source

pub fn new(singleton: IdentitySingleton, store: StoreRecord) -> Self

Bundles a (singleton, store) pair. Does NOT authenticate singleton.lineage – see the type doc: the caller MUST have resolved lineage on-chain (WU3) before trusting Self::verify.

Source

pub fn outcome(&self) -> PairingOutcome

Re-evaluates both pairing links, reporting each independently (for diagnostics).

Source

pub fn verify(&self) -> bool

Re-runs the section 7 pairing predicate over the bundled records (BOTH links).

Returns true iff discovery AND authority hold – but ONLY sound when singleton.lineage was verifier-resolved on-chain as the DID’s authentic singleton lineage (see the type doc). A true from an untrusted producer does NOT prove chain ownership.
