Appearance

@tamga-network/trust ​

Signed trust lists (who may issue which document, since when, and their status) behind one TrustSource interface. Verifies the list of lists, the national lists and the public anchor log; answers in three values (YES / NO / UNKNOWN). @tamga-network/trust/core is the platform-independent core (React Native too). Wallet unit attestation checks (verifyWalletAttestation, WUA/WIA) live here too.

Install ​

sh
npm install @tamga-network/trust

Usage ​

ts
import { fetchListTrustSource, verifyJws } from "@tamga-network/trust";

const { source } = await fetchListTrustSource("https://trust.tamga.network", httpGet, {
  rootFingerprints: PINNED_ROOTS, // from tamga.network/trust-anchor, fixed in your configuration
  verifyJws,
});
source.issuers();                                // registered institutions
source.relyingPartyByDnsName("example.com");      // a verifier's registration (permanent domain) and allowed fields
source.relyingParty("x509_hash:…");                // the same record, by the request's client_id (HAIP 1.0)
source.isCredentialAcceptable(issuerId, iat);    // "YES" | "NO" | "UNKNOWN" — judged on the issue date

A complete, tested version: examples/04-check-institution.
