Verifiable credential infrastructure
Credentials that prove themselves.
Infrastructure for issuers to sign, batch, and anchor credentials on Ethereum L2. W3C Verifiable Credentials 2.0 + Blockcerts v3 + Open Badges 3.0, by design, from day one. Recruiters, employers, and AI agents can confirm a credential's authenticity without trusting us — or anyone.
Built on open standards
Anchored on
- Ethereum L2 (Base — OP Stack)· Coinbase's open-source L2 built on Optimism's OP Stack
Privacy by architecture
- GDPR-aware schema split· On-chain pseudonymous IDs; off-chain PII under tenant-scoped RLS
How it works
Three steps, one trust anchor
Every credential issued through LearnCoin is signed, batched, anchored, and independently verifiable. The verifier never needs to trust us — the signed document and the on-chain anchor speak for themselves.
Issuers sign
Your platform calls POST /v1/batches with a list of credentials. LearnCoin signs each in OB 3.0 + Blockcerts v3 format using a per-tenant key held in HSM-protected GCP KMS.
LearnCoin anchors
Credentials are Merkle-batched and the root is written to Ethereum L2 (Base — OP Stack) as a single transaction. Per-credential anchoring cost is effectively zero at scale.
Anyone verifies
Each credential gets a shareable verify URL. Recruiters, HR systems, and AI agents follow the URL, read the signed document, and confirm the on-chain anchor — no LearnCoin API call required.
Built for issuers
Schools, employers, training platforms
Any organization that issues credentials can use LearnCoin as their cryptographic backbone. Your brand stays in front of the recipient — LearnCoin is invisible infrastructure. Your certificate design, your domain, your relationship.
- Multi-tenant issuance API with per-tenant signing keys.
- GDPR-aware schema — pseudonymous on-chain, PII in erasable off-chain storage.
- Magic-link claim flow + shareable public verify pages.
- Webhooks for batch anchoring, revocation, and claim events.
