Digital identity & credentials

Verifiable credentials people hold and present themselves — proving what is needed without exposing everything else.

What are verifiable credentials?

Verifiable credentials are digitally signed claims — a qualification, a licence, an age, an employment status — that the holder stores and presents. A verifier can confirm the issuer's signature cryptographically without contacting them, and selective disclosure allows proving one fact without revealing the whole document.

Prove the claim, not the document

Today, proving you are over eighteen usually means handing over a document containing your full name, address and date of birth. The verifier learns far more than they needed, stores it, and becomes a target. Selective disclosure removes that: the holder proves the specific claim and nothing else.

This matters most where the same credential is presented repeatedly to parties who should not accumulate personal data. It is a privacy improvement first and a convenience improvement second, and it is worth framing that way with stakeholders.

Deliverables

What you receive

  • Credential schema and issuance infrastructure
  • Holder wallet or app integration
  • Verifier interface with selective disclosure support
  • Revocation registry and status checking
  • Key management and recovery procedures

Engagement shape

Twelve to twenty-four weeks. This is a standards-heavy area and we scope a pilot cohort before full rollout.

Tooling

What we typically build with

  • W3C Verifiable Credentials
  • DIDs
  • Polygon ID
  • Hyperledger Aries
  • Node.js
  • React Native

Stack decisions follow the problem. This is where we usually start, not a fixed menu.

Frequently asked

Questions we get about this

Is this compatible with Aadhaar or DigiLocker?

They solve overlapping problems in different ways, and integration depends on the specific use case and the permissions available to you. We assess interoperability during design rather than assuming it, because getting this wrong late is costly.

What if someone loses their phone?

Recovery is the hardest part of these systems and must be designed up front. Options include issuer-assisted reissuance, backup key escrow and social recovery, each with different security and usability trade-offs. Any system without a recovery answer will fail in the field.

A discovery call is a working session on your constraint, not a sales pitch.
