X16 ACQUIRED ZAKAPI Zero-Knowledge Identity & Verifiable Data Platform
Zero-Knowledge Identity & Verifiable Data Platform: know the answer, verify the computation, and never see the data.
Zakapi is a zero-knowledge identity, credential, and verifiable data platform built for high-trust environments. Verify identity, eligibility, and compliance without exposing raw personal data or underlying database records.
IDENTITY
ELIGIBILITY
COMPLIANCE
Trusted by governments, regulated enterprises, fintech platforms, telecom operators, and digital services to deliver privacy-first identity and verifiable data infrastructure.
Share Proofs, Not Data
Zakapi replaces document exchange and raw data access with cryptographic proofs. Services ask precise questions and receive verified answers backed by zero-knowledge proofs — without exposing unnecessary personal data, documents, or database records.

VALUE PROPOSITION
Zakapi returns the answer plus a non-interactive zero-knowledge proof that the answer is correct. The verifier gets certainty. The user keeps privacy. The underlying records stay where they belong.

Share Proofs, Not Data
Zakapi transforms identity and compliance workflows from document exchange into proof-based verification. Instead of over-collecting personal information, services ask precise questions such as:
  • Is this person over 18?
  • Has this customer passed KYC in the last 12 months?
  • Is this license valid and not revoked?
  • Is this user eligible for a service, benefit, or transaction?
  • Was this policy query executed correctly on the committed dataset?
  • Is this person a registered voter in the correct district?
  • Is this passport valid and unexpired?
  • Is this SIM registration compliant with local regulations?
  • Is this patient’s insurance coverage currently active?
  • Is this professional credential authentic and in good standing?
  • Is this user authorized to work in this country until the stated date?
  • Is this account holder not on a sanctions or watch list?
Why Current Identity Systems Break
Today’s identity and compliance systems rely on document uploads, duplicated data, and opaque backend checks. This creates massive data exposure, slow onboarding, high operational costs, and weak auditability.
Organizations are forced to choose between privacy, compliance, and user experience.
Zakapi removes that trade-off by replacing data sharing with proof-based verification.
Why Zakapi
Privacy by Design
Only the required answer is shared. No raw data leaves the user or issuer systems.

Stronger Security
No centralized PII honeypots. Reduced breach surface and insider risk.

Compliance by Default
GDPR, KVKK, eIDAS aligned through cryptographic enforcement.

Open Standards
Built on W3C VC, DIDs, OIDC. No vendor lock-in.

Future-Proof Infrastructure
Zero-knowledge proofs, verifiable SQL, modular architecture.

Better User Experience
Reusable credentials. Instant verification. No document uploads.
How Zakapi Works
1. Issuers
Governments, banks, and institutions issue credentials or anchor trusted datasets.
2. Holders
Users store credentials in a secure wallet and control what they share.
3. Verifiers
Services request proof of identity, eligibility, or policy outcomes.
4. Proof Generation
Zakapi generates a non-interactive zero-knowledge proof.
5. Verification
The verifier checks the proof without accessing raw data.

TECH
Verifiable SQL + Zero-Knowledge Identity

Zakapi combines identity infrastructure with a Halo2-based, SQL-aware zero-knowledge proof engine. It proves both user attributes and database-backed policy outcomes without revealing underlying records.
Features:
Committed Data
Proofs tied to cryptographic database commitments.
SQL Circuits
Policies expressed as filters, joins, aggregations, and predicates.
Non-Interactive Proofs
Offline verifiable, tamper-proof, replayable.
Open Identity Layer
W3C credentials, DIDs, OIDC flows.
PoneglyphDB uniquely supports both zero-knowledge proofs and arbitrary SQL queries, unlike other systems which only support one or neither, making it the only fully verifiable and flexible solution.

FAQ
  • What is Zakapi?
    Zakapi is a zero-knowledge identity, credential, and verifiable data platform that enables organizations to verify identity, eligibility, and compliance without accessing or storing raw personal data. It replaces document-based verification with cryptographic proofs that guarantee correctness while preserving privacy.
  • How is Zakapi different from traditional identity verification systems?
    Traditional systems rely on document uploads, data duplication, and opaque backend checks. Zakapi replaces this with reusable credentials and non-interactive zero-knowledge proofs, allowing services to verify facts without seeing underlying data, reducing friction, cost, and risk.
  • What does “Compliance by Default” mean?
    Compliance by Default means Zakapi enforces regulatory principles like data minimization, purpose limitation, and auditability at the protocol level. Systems can only request specific proof-based outputs (e.g., “over 18” or “KYC valid”), ensuring they cannot over-collect or misuse personal data. This aligns with frameworks such as GDPR, KVKK, eIDAS, and NIST 800-63.
  • What is a zero-knowledge proof in Zakapi?
    A zero-knowledge proof allows one party to prove that a statement is true without revealing the underlying data. In Zakapi, this means proving identity attributes, compliance status, or policy outcomes without exposing sensitive personal or database information.
  • Can Zakapi verify database-backed policies (like KYC or AML)?
    Yes. Zakapi uses committed datasets and SQL-aware zero-knowledge circuits to prove that a policy (e.g., KYC passed, not on sanctions list) was correctly evaluated against trusted data, without revealing the records themselves.
  • What is verifiable SQL and why does it matter?
    Verifiable SQL means that queries such as filters, joins, and aggregations can be proven cryptographically. Zakapi ensures that decisions (like approvals or eligibility checks) are not just results, but provably correct computations over authenticated datasets.
  • Does Zakapi store personal data?
    No. Zakapi minimizes or eliminates the need to store personal data. Credentials remain in user-controlled wallets or with trusted issuers. Verifiers receive only proofs and minimal outputs, reducing data liability and breach risk.
  • How does Zakapi improve onboarding and conversion rates?
    Zakapi enables instant verification using reusable credentials and proofs. Users no longer need to upload documents or wait for manual reviews, reducing onboarding time from days to seconds and significantly improving conversion rates.
  • Is Zakapi compatible with existing identity standards?
    Yes. Zakapi is built on open standards including W3C Verifiable Credentials, Decentralized Identifiers (DIDs), and OIDC-based flows. This ensures interoperability across systems, ecosystems, and jurisdictions.
  • What industries can use Zakapi?
    Zakapi is designed for high-trust environments including governments, banking and fintech, telecom, healthcare, education, insurance, and online platforms that require strong identity verification and regulatory compliance.
  • How does Zakapi handle audits and regulatory reporting?
    Zakapi generates cryptographic proof logs that can be independently verified. Instead of exposing sensitive data during audits, organizations can provide mathematical evidence that policies were correctly applied.
  • Is Zakapi secure?
    Yes. Zakapi uses advanced cryptography, non-interactive zero-knowledge proofs, and strong encryption standards. It reduces attack surfaces by avoiding centralized storage of sensitive data and ensures integrity through verifiable computation.
  • What is the Zakapi Wallet?
    The Zakapi Wallet is a secure, non-custodial identity wallet that stores credentials and generates proofs on demand. It gives users full control over their identity data and what they share.
  • How do developers integrate Zakapi?
    Developers can integrate Zakapi using APIs, SDKs, and widgets. They define policies, and Zakapi handles proof generation and verification.
