# FAQ

Frequently asked questions about ZK-Provenance.

## General

**Q: What is ZK-Provenance?** A: ZK-Provenance is a decentralized document verification protocol. It lets you prove a document is authentic without revealing its contents, using Zero-Knowledge proofs on Solana.

**Q: Is it live?** A: Yes! ZK-Provenance is live on Solana Devnet at [zkprovenance.app](https://zkprovenance.app). Mainnet is planned for Q4 2026.

**Q: Is it free to use?** A: Free tier includes 10 proofs/month. Pro plan (0.5 SOL/month) offers unlimited proofs.

**Q: Do I need to create an account?** A: No. Your Solana wallet is your identity — no email or password needed.

## Privacy & Security

**Q: Does ZK-Provenance see my data?** A: No. Your data is hashed locally in your browser using Poseidon-128. The original data never leaves your device.

**Q: Can someone reverse-engineer my data from the proof?** A: No. The Poseidon hash is one-way — mathematically impossible to reverse. The ZK proof reveals nothing about the original data.

**Q: Is the trusted setup secure?** A: Yes. We use the Powers of Tau ceremony by Hermez Network — a public ceremony with thousands of participants. If even one participant was honest, the setup is secure.

**Q: Can someone fake a proof?** A: No. Groth16 proofs are computationally sound — a dishonest prover cannot generate a valid proof without knowing the actual data.

## Technical

**Q: What file types are supported?** A: PDF, CSV, and JSON files are supported. Text input is also available.

**Q: How long does proof generation take?** A: Approximately 1,500–3,000ms (1.5–3 seconds) in the browser.

**Q: What is the proof size?** A: 288 bytes — regardless of the document size.

**Q: What wallet do I need?** A: Phantom or Solflare wallets are supported. Set to Devnet network.

**Q: How much SOL do I need?** A: \~0.002 SOL per attestation for transaction fees. Get free devnet SOL at [faucet.solana.com](https://faucet.solana.com).

## Compliance

**Q: Does a ZK-Provenance proof legally prove HIPAA compliance?** A: Currently, ZK proofs are not legally recognized as primary compliance evidence in most jurisdictions. A ZK-Provenance attestation proves document authenticity and timestamp — it serves as a strong supplementary evidence layer. Legal recognition is evolving rapidly with EU eIDAS 2.0 framework.

**Q: Which compliance frameworks are supported?** A: GDPR, HIPAA, SOC2, ISO27001, and CCPA.

**Q: Can I prove compliance for multiple frameworks at once?** A: Yes. The "Full Suite" policy applies all 5 frameworks simultaneously in a single proof.

## Token

**Q: What is the $\[TICKER] token?** A: $\[TICKER] is ZK-Provenance's utility token — used for verifier staking, governance, and protocol access. Token ticker is TBD.

**Q: When is the token launching?** A: Token launch is planned for Q3 2026 on Pump.fun as a 100% fair launch.

**Q: Will there be a presale or whitelist?** A: No. 100% fair launch — no presale, no whitelist, no VC allocation.

## Support

**Q: Where can I get help?** A: Email us at <hello@zkprovenance.io> or reach out on Twitter [@ZkProvenance](https://x.com/ZkProvenance).

**Q: How do I report a bug?** A: Email <hello@zkprovenance.io> with details. Bug bounty program coming Q3 2026.
