Have some questions about Persona Protocol?
Hopefully, you'll find the answers here! If not then please don't hesitate to reach out to us on discord - there are no stupid questions!
What makes Persona different from other “decentralized identity” projects?
Most protocols focus on storage (where data lives). We focus on computation (how data is used).
Example: While others let you “store” your medical records, Persona lets hospitals train AI models on encrypted patient data without ever decrypting it.
Tech Edge: We combine TEEs (hardware security), FHE (encrypted computation), and ZK proofs (selective disclosure) into one stack—others use just one
How do you protect privacy if AI needs my data?
Your data stays encrypted during processing. Think of it like this:
Old Way: Give Netflix your watch history → They store it → Recommend shows.
Persona Way: Netflix sends an AI model to your vault → It analyzes encrypted viewing habits → Returns recommendations without Netflix ever seeing your data. Powered by Fully Homomorphic Encryption (FHE), tested by JPMorgan for fraud detection.
Why launch now? Didn’t privacy protocols fail in 2017-2020?
Three seismic shifts:
AI Crisis: GPT-5 is hitting accuracy walls due to lack of private data.
Regulatory Teeth: GDPR fines hit $3B+; eIDAS 2.0 mandates EU digital IDs by 2025.
Tech Readiness: FHE libraries (IBM) and TEEs (Intel SGX) are now production-grade. Previous protocols were like electric cars without batteries—we have the infrastructure now.
Can I actually make money with my data?
Yes, but not by “selling” it. You license privacy-preserving insights:
Scenario 1: Earn $5/month letting brands target “dog owners in NYC” via ZK proofs (no address leaks).
Scenario 2: Get paid in crypto for contributing encrypted fitness data to medical studies. No raw data changes hands—only value derived from it.
How do you handle KYC/AML without exposing my ID?
For Users: Prove you’re “over 18 + resident of Germany” via ZK proofs from your passport scan. The app learns only “yes/no.”
For Banks: Comply with regulations using proofs instead of storing copies of IDs. Piloted with a European neobank to cut KYC costs by 40%.
What stops hackers from stealing my vault data
TEEs (Trusted Execution Environments): Data is processed in hardware-sealed black boxes (used by Microsoft Azure)
MPC (Multi-Party Computation): Your data is split into encrypted shards; no single breach reveals anything.
Zero-Trust Design: Even Persona’s team can’t access your vault.
How does this help startups compete with Big Tech?
Example: A travel startup can personalize trips using your encrypted Uber/Lyft history. No need to mine data like Google—just query the privacy-safe insights
Cost: Integration takes <1 week via our APIs, vs. years to build data pipelines.
