Prove more.Reveal less.

Verify trusted state, prove eligibility privately, then unlock an on-chain action. A testnet demonstration on Robinhood Testnet.

Verify the factProve it privatelyUnlock on-chain

The exact value stays on your device. Only a proof that it met the rule is checked on-chain.

01 — The idea

Verifiable facts should not require public data.

Most on-chain checks work by publishing the fact itself. That makes the fact easy to trust and impossible to keep private. Private data has the opposite problem: no one else can rely on it.

This protocol pairs the two. A trusted issuer seals a fact in an attestation. You then prove that the sealed fact meets a rule, without showing the fact. The rule is enforced by a smart contract, so anyone can inspect that it was applied.

What a verifier sees about the same fact. An illustration, not real data.

02 — How it works

From a trusted fact to a verified action.

Four steps. The path crosses the privacy boundary three times, and the value never does.

Private: stays on your devicePublic: on the selected testnet

  1. On your device

    Trusted state

    A trusted issuer vouches for a fact about your wallet. You receive the private details and they stay with you.

    Public

    • Your wallet address

    Private

    • The value and a random salt
    • Known to you and the issuer only

  2. On-chain

    Attestation

    The issuer registers a sealed fingerprint of the fact, called a commitment. The value itself is never published.

    Public

    • The commitment
    • The wallet it is bound to
    • Expiry and revocation status

    Private

    • The value
    • The salt

  3. On your device

    Private proof

    Your device proves that the sealed fact meets the policy and matches the on-chain commitment, without sending the value anywhere.

    Public

    • The policy and its threshold
    • The proof itself

    Private

    • The value
    • The salt

  4. On-chain

    Verified execution

    A contract checks the sender, the commitment, the policy and the proof in one transaction, then unlocks the action: a governance vote, or a loan in the Lending V2 market.

    Public

    • The proof and public inputs
    • Your wallet address
    • The access result and transaction

    Private

    • The value stays unpublished

03 — The trust layer

Trust is verified. Privacy is preserved.

DOJANG establishes project-defined eligibility. BOJAGI proves that eligibility without exposing the private value. DAO governance and Lending put both to work.

The trust layer

01Credential layer · public

DOJANGCredential Access

Credentials that contracts can check.

A project credential links one wallet to an eligibility record on-chain, with a policy, an expiry and a way to revoke it. Contracts read it before they allow an action.

  • Policy 4 · DAO access
  • Policy 3 · Lending

Use caseA project issues a credential to a member wallet, and any contract can confirm it before the member acts.

Open DOJANG

02Proof layer · private

BOJAGIPrivate Eligibility Proof

Prove it. Keep the value private.

Your browser proves that the private value behind a credential meets a rule. Only the proof goes on-chain; the value and its salt never leave your device.

  • Policy 3 · Lending proof
  • Zero-knowledge

Use caseShow that you meet a lending requirement without publishing the number behind it.

Open BOJAGI

03Governance layer · public

DAOCredential-Gated Governance

Governance for credential holders.

Holders of an active project credential propose and vote on-chain. Each eligible wallet counts once per proposal, and every vote is public.

  • Policy 4 · Voting
  • Public votes

Use casePropose a change to the DAO's own credential-validity rule, then let eligible holders vote on it.

04 — Lending

Borrow with a proof, not a disclosure.

Lending V2 supports supply, collateral, borrow, repay and withdraw on Robinhood Testnet. The protected actions require a valid project-issued policy-3 credential and a genuine zero-knowledge proof, checked again by the contract.

Test tokens and synthetic test prices. A credential-gated demonstration of lending, not an exchange: there is no spot or derivatives trading. Credentials are issued by this project, not by GIWA, Dojang or Upbit.

05 — Roadmap

Live on testnet. Production still ahead.

The protocol is deployed and running on Robinhood Testnet (chain 46630). The full public wallet journeys are still being confirmed, and production readiness is future development.

  1. Phase 01Completed

    Protocol foundation

    • Project credential registry: commitments, policies, expiry and revocation
    • A Noir eligibility circuit, proofs made in the browser and a generated Solidity verifier
    • DAO governance and Lending V2 contracts, tested locally with genuine proofs

  2. Phase 02Completed

    Robinhood Testnet deployment

    • Ten project contracts deployed and read back from chain 46630
    • Synthetic test prices set and controlled demo tokens minted
    • Two policy-4 DAO credentials issued

  3. Phase 03Live on Testnet

    Live testnet demo

    • Contract status and explorer links read live from the network
    • DAO and Lending screens connected to the deployed contracts
    • Demo tokens and test prices in place for the first journeys

  4. Phase 04In Progress

    Public testnet journeys

    • A DAO proposal, vote, finalization and execution from real wallets, with receipts
    • Policy-3 credential issuance, then supply, borrow and repay with a genuine proof
    • Contract source published and verified on the explorer

  5. Phase 05Future Development

    Production readiness

    • An independent security audit and review
    • Production-grade price oracle infrastructure
    • A mainnet launch decision, only once the work above is complete
