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

Twelve to twenty-four weeks. This is a standards-heavy area and we scope a pilot cohort before full rollout.
Stack decisions follow the problem. This is where we usually start, not a fixed menu.
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.
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.
A short note is enough. You'll hear back from the team, not a bot — usually within one working day.
