Class: NullifierStore

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:45

Constructors

Constructor

new NullifierStore(fmd): NullifierStore;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:50

Parameters

Parameter	Type
fmd	NullifierFeed

Returns

NullifierStore

Accessors

size

Get Signature

get size(): number;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:67

Nullifiers mirrored so far.

Returns

number

Methods

has()

has(nf): boolean;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:65

True if this nullifier was consumed on-chain as of the last sync. A stale mirror can only under-report, so this never reports a live note as spent (barring the truncation collision described at WIRE_BYTES).

Parameters

Parameter	Type
nf	bigint

Returns

boolean

---

loadState()

loadState(state): void;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:53

Parameters

Parameter	Type
state	NullifierStoreState

Returns

void

---

saveState()

saveState(): NullifierStoreState;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:54

Returns

NullifierStoreState

---

sync()

sync(opts?): Promise<NullifierSyncSummary>;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:59

Fetch chunks since the last sync, fold them into the set, then persist. Idempotent: the tail chunk is re-fetched every sync and already-mirrored entries are skipped by sequence.

Parameters

Parameter	Type
opts?	NullifierSyncOpts

Returns

Promise<NullifierSyncSummary>

---

withPersistence()

static withPersistence(fmd, persistence): Promise<NullifierStore>;

Defined in: @lelantos-org/sdk/dist/sync/nullifier-store.d.ts:52

Build a NullifierStore and restore any previously persisted state.

Parameters

Parameter	Type
fmd	NullifierFeed
persistence	NullifierPersistence

Returns

Promise<NullifierStore>
