Institutional privacy layer · for digital assets

Private by design.
Verifiable by proof.

Qedis is a privacy layer for verifiable confidentiality across any chain. Values stay private to their owners. Networks verify commitments, proofs, conservation, range and membership — without ever seeing the underlying data.

Institutions can’t operate on a public ledger.

Balances, counterparties, and flows are commercially sensitive. Yet the alternative on offer — decrypting your data inside trusted hardware — asks you to trust an enclave, an attestation chain, and a single master secret. Qedis takes the other path: confidentiality enforced by mathematics, not by hardware you have to trust.

Trusted-hardware privacy

  • Your data is decrypted inside a validator’s enclave
  • Security rests on hardware integrity & attestation
  • One master secret can unwind everything if breached
  • Auditor access is a role grant

Qedis — verifiable confidentiality

  • Values are never decrypted — anywhere
  • Security rests on published cryptography
  • No master secret. No enclave.
  • Auditor access is a cryptographic, provable disclosure
What Qedis is

Confidentiality you can prove — not confidentiality you have to trust.

Confidential values

Amounts and balances are committed, never published. Qedis never sees, stores, or decrypts the underlying value — it stays with its owner.

Verifiable by proof

The network checks zero-knowledge proofs — range, conservation, membership — at consensus. It learns only valid or invalid, nothing more.

Non-custodial disclosure

When supervision requires it, an authorised party opens exactly what they’re entitled to — with an issued viewing key, verifiable against on-chain state.

Built for any chain

A substrate-agnostic runtime designed to sit at the consensus layer, so the same guarantees travel across ecosystems — not locked to one network.

How it works

Commit. Prove. Verify.

Three moves keep data private while keeping the network honest.

  1. 01

    Commit

    A value is sealed into a binding cryptographic commitment. It’s published; the value is not. Equal amounts look different on-chain.

  2. 02

    Prove

    The owner attaches zero-knowledge proofs — that an amount is well-formed, that a transfer conserves value, that a party is a member of an allow-list — authorised with post-quantum signatures.

  3. 03

    Verify

    The runtime verifies natively, atomically, at the consensus layer — accepting or rejecting the state change without the value ever being exposed.

Selective disclosure for audit and supervision is delivered separately and cryptographically: an authorised viewer opens only what a grant permits, and can verify it against the public commitment.

Capabilities

A confidentiality toolkit for regulated finance.

Confidential values

Hide amounts and balances while proving they’re well-formed.

Range proofs

Prove a hidden value is non-negative and in-bounds — no overflow, no “negative” amounts.

Conservation

Prove a transfer balances — value is neither created nor destroyed — in zero knowledge.

Membership

Prove an address is allow-listed (or absent from a list) without revealing identity.

Post-quantum signatures

Authorisation built on ML-DSA — a hybrid, post-quantum signature layer.

Selective disclosure

Cryptographic viewing keys for auditors and supervisors — provable, scoped, revocable.

For institutions

Designed for the people who answer to a regulator.

Data minimisation

Keep amounts and counterparties off the public ledger by default — while still proving every transaction is valid.

Supervisory access

Grant lawful, scoped visibility to auditors and supervisors through issued viewing keys — disclosure that is cryptographic and verifiable, not a trust-me access role.

Post-quantum posture

A signature and attestation layer built for the post-quantum era, with a clear migration path as standards harden.

No single point of compromise

There is no master secret whose breach unwinds confidentiality, and no enclave to trust. Privacy is a property of the mathematics.
