AETHER / Services / Identity
§ 01 — BIOMETRIC IDENTITY

Prove who you are without revealing anything.

A zero-knowledge biometric layer bound to a sovereign DID. KYC once, then reuse it across supported jurisdictions. Built for institutions that have to clear compliance without adding friction at onboarding.

The core primitive

AETHER Identity is the trust anchor for every transaction on the network. Each account is bound to a decentralized identifier (DID) that holds verifiable credentials issued by accredited KYC providers, banks and government registries. The raw documents stay with the issuer.

A counterparty that needs to confirm one fact about a user (age, jurisdiction, sanctions status, accredited investor status) requests a zero-knowledge proof. The proof confirms that fact without disclosing the data behind it, and a fresh biometric challenge binds it, so nobody can replay it.

What it replaces

How it works

STEP 01

Enrol

The user enrols at any accredited issuer. The issuer seals the biometric template inside an HSM-backed enclave; raw biometrics never leave the device.

STEP 02

Bind

AETHER creates a DID, binds it to the sealed template, then issues verifiable credentials against it: KYC tier, jurisdiction, sanctions clear.

STEP 03

Prove

On each transaction the user signs a fresh challenge biometrically. The rail delivers a ZK proof of the required attribute to the counterparty.

What you get

Compliance posture
FATF Travel Rule, MiCA Title II, eIDAS 2.0 wallet-ready, FIDO2 / WebAuthn at the transport layer. Attested on every transaction, never point-in-time.
Privacy guarantee
Selective disclosure via BBS+ signatures. Counterparties learn the answer and nothing else. Audit trails store proofs instead of personal information.
Recovery
Threshold-based social recovery using MPC. No single party, AETHER included, can resurrect a lost identity alone.
Onboarding time
Median issuer flow: under 4 minutes for retail tiers. Institutional onboarding integrates with existing CDD providers via standard webhooks.
