Introduction to BaseID

BaseID is an open-source digital identity infrastructure built in Rust. It provides everything needed to issue, hold, present, and verify digital credentials across multiple formats and protocols. 35 crates, 1003 tests, all passing.

What BaseID Provides

Section titled “What BaseID Provides”
  • Credential Formats: W3C Verifiable Credentials (JWT-VC + Data Integrity), ISO 18013-5 mDL, SD-JWT VC, BBS+ unlinkable credentials, Hyperledger AnonCreds
  • Protocols: OID4VCI 1.0 (issuance), OID4VP 1.0 (presentation), SIOPv2 (authentication), DIDComm v2 (messaging), HAIP 1.0 (high assurance)
  • DID Methods: did:key, did:web, did:jwk, did:peer (numalgo 0/2/3/4), did:webvh
  • Privacy: BBS+ selective disclosure, ZK predicates, cryptographic accumulator revocation, credential delegation
  • Compliance: PCTF (58 tests), eIDAS 2.0, HAIP 1.0, MOSIP, cross-framework assurance mapping
  • SDKs: Python, Go, Web (WASM), Android (Kotlin/UniFFI), iOS (Swift/UniFFI), React Native
  • Applications: Reference wallet (web, browser extension, mobile), issuer portal, verifier portal, interactive playground
  • Server: HTTP API with 40+ endpoints (OID4VCI, OID4VP, DIDComm, admin REST)

Who is it for?

Section titled “Who is it for?”
  • Government agencies building digital identity programs (PCTF-aligned, bilingual EN/FR)
  • Enterprises implementing credential-based verification (Python/Go server SDKs)
  • Developers building identity wallets, issuers, or verifiers (Rust + WASM + mobile)
  • Standards bodies evaluating credential format implementations

Standards Compliance

Section titled “Standards Compliance”

BaseID implements international standards including:

  • PCTF (Canada) — full compliance with all 5 components (58 tests), bilingual policy engine
  • eIDAS 2.0 (EU) — PID data model, QEAA, LoA mapping (14 tests)
  • HAIP 1.0 — High Assurance Interoperability Profile with algorithm/format constraints (12 tests)
  • MOSIP — offline QR verification for low-connectivity environments (16 tests)

Cross-framework assurance level mapping (PCTF Level 1-3 ↔ eIDAS ↔ NIST 800-63 ↔ TDIF) is built-in.

Project Structure

Section titled “Project Structure”

The project is organized as a Rust workspace with the following layers:

  1. Foundation — shared types, cryptographic primitives (Ed25519, P-256, P-384), bilingual errors
  2. Identity — DID methods (did:key, did:web, did:peer, did:webvh) and resolution
  3. Credentials — format-specific implementations (JWT-VC, Data Integrity, SD-JWT, mDL, BBS+, AnonCreds)
  4. Privacy — BBS+ signatures, delegation chains, cryptographic revocation
  5. Protocols — OID4VCI, OID4VP, SIOPv2, DIDComm v2, ISO 18013-7
  6. Transport — HTTP client (reqwest), DIDComm delivery, BLE, NFC
  7. Components — wallet-core, issuer-core, verifier-core, encrypted storage, PCTF compliance
  8. Compliance — HAIP, eIDAS, MOSIP, PCTF, trust graphs, identity proofs
