Digital Identity on PYRAX
Government digital identity underpins access to every public service, yet most national ID and login schemes centralize citizen data in honeypot databases that leak and over-share. PYRAX enables self-sovereign identity where citizens hold their own credentials and prove attributes - over 18, a resident, a licensed professional - through zero-knowledge selective disclosure, revealing a single fact instead of an entire dossier.

What's broken today
How PYRAX transforms it
Concrete network elements mapped to this business.
Self-sovereign identity + ZK selective disclosure
Citizens hold credentials in their own wallet and prove a single claim - over 18, a citizen, resident of a district - with a zero-knowledge proof that reveals nothing else, ending the over-sharing of full ID documents.
Shielded-by-default privacy with viewing keys
Personal attributes stay encrypted on-chain and private to the citizen, while an issuing agency or auditor uses a scoped viewing key for lawful, read-only verification instead of holding a plaintext copy.
eth_getProof tamper-proof registries
Credential issuance, revocation, and status live in a verifiable registry any relying party can check cryptographically against chain state - no calling back to a central authority's database.
Multi-VM smart contracts (EVM / WASM / Cairo)
Issuance rules, expiry, revocation lists, and cross-agency trust frameworks are encoded as deterministic contracts, with Cairo proving ZK attribute checks natively.
BLS proof-of-stake finality
Credential issuance and revocation take effect with instant, irreversible finality, so a revoked or updated identity is immediately authoritative everywhere it is checked.
Buildathon: dApp ideas
Ship-ready concepts for digital identity on PYRAX.
SovereignID
01Citizen-held national identity wallet that issues ZK proofs of attributes without ever exposing the underlying documents.
AgeProof
02Selective-disclosure age gate that proves a citizen is over 18 or over 65 for services without revealing birthdate or name.
ResidentKey
03Proof-of-residency credential for district services and voting eligibility, verifiable without disclosing the full address.
RevokeList
04Tamper-proof credential-revocation registry that relying parties verify via eth_getProof rather than a central call.
CrossAgency
05Interoperability layer letting a credential issued by one agency be trusted and reused across others through a shared trust framework.
ConsentLog
06Citizen-controlled access log where every identity check is recorded and the holder can see and revoke who queried them.
GuardianRecover
07Social-recovery contract that lets trusted guardians restore a lost identity wallet without any central custodian.
ProProof
08Professional-license attestation (doctor, engineer, notary) provable via ZK to employers and the public without a lookup portal.
