Pronunciation
[ahy-den-ti-tee klayms pahyp-lin]
Analogy
Like a water treatment plant where raw water is collected, filtered, treated, and delivered to consumers.
Definition
An end‑to‑end process for issuing, verifying, transforming, and revoking identity claims—from data collection through on‑chain anchoring and consumption by relying parties.
Key Points Intro
Claims pipelines ensure trustable identity data flows from issuers to verifiers.
Key Points
Issuance: Trusted authority creates signed claims.
Verification: Checks signature and revocation status.
Transformation: Maps claims to required schemas.
Anchoring: Records claim hashes on‑chain for audit.
Example
A university issues a verifiable degree credential; a job portal verifies on‑chain anchor and maps fields to its applicant schema.
Technical Deep Dive
Pipeline uses W3C VC data model. Issuer signs claim JSON‑LD with JSON‑LD proof. Anchor service batches claim hashes into Merkle tree, writes root in a smart contract. Verifier fetches proof and root, runs `verifyMerkleProof()` and signature check.
Security Warning
Weak key management at issuer disrupts entire pipeline; use HSM for signing.
Caveat
Latency between issuance and anchoring can delay verification.
