StoreUpdateAuthority

dig_identity::authority

Struct StoreUpdateAuthority 

Source 
pub struct StoreUpdateAuthority {
    pub owner_puzzle_hash: Bytes32,
    pub delegations: Vec<WriterDelegation>,
    pub current_height: u32,
}
Expand description

The store singleton’s CURRENT on-chain update authority — everything needed to DECIDE whether a caller may advance the store root, as resolved from chain by a higher-level chain source.

Fields§

§owner_puzzle_hash: Bytes32

The store singleton’s current owner puzzle hash. A caller whose puzzle hash equals this holds full update authority.

§delegations: Vec<WriterDelegation>

The CHIP-0035 delegations currently recorded on the store (any kind; validity is decided by Self::authorizes, not by the source).

§current_height: u32

The current chain height, used to evaluate delegation expiry.

Implementations§

Source§

impl StoreUpdateAuthority

Source

pub fn authorizes(&self, caller_puzzle_hash: Bytes32) -> bool

Whether caller_puzzle_hash is authorized to advance (update) this store’s root.

True iff the caller is the current owner OR holds a currently-valid write-granting delegation. Fails closed: an unknown caller, a revoked or expired delegation, or an oracle-only delegation all return false.

§Misuse boundary (MUST read)

This is a pre-flight predicate over chain facts the CALLER has already authenticated. It MUST NOT be evaluated over data supplied by the party being authorized: whoever controls owner_puzzle_hash or delegations controls the answer outright. Resolve those fields from chain (see crate::resolve’s trust model) before calling.

A true here is NOT proof of on-chain authority — only the chain, accepting the spend, is that. Use this to decide whether an update is worth ATTEMPTING (and to fail fast when it is plainly not), never as the sole authorization for an action with consequences.
