Prove credentials without revealing them. Pay zero fees for preserving privacy.

Horizen adaptation of zk-attest — replaces Hedera HCS/HTS with ZEN token staking and ZenKinetic privacy gate integration.
- Issuer signs a credential commitment (same as zk-attest)
- User generates a ZK proof (same circuit)
- ZenKinetic gate scores the proof's negentropy — privacy-preserving = 0% fee
- ZEN staking grants access — Basic tier (100 ZEN) for attestations
- Attestation settles on Horizen Base L3 as a confidential NFT
use horizen_attest::{AttestationSession, AttestationKind};
let session = AttestationSession::new(AttestationKind::Age, 18, 0.95, 100.0);
let result = session.evaluate();
println!("Gate: {:?}", result.gate_decision); // Allow
println!("Fee: {} bps", result.fee_bps); // 0
println!("Negentropy: {:.1} bits", result.negentropy_bits);
println!("Access: {}", result.access_granted); // true| Kind | Base Confidence | Use Case |
|---|---|---|
| Age | 100 | Government ID-backed age |

This is the Horizen-native adaptation of zk-attest. The ZK circuit and proof generation are the same; the chain integration changes from Hedera HCS/HTS to Horizen Base L3 with ZEN staking and ZenKinetic privacy gating.
horizen-attest brings zero-knowledge attestations to Horizen Base L3. This is the Horizen-native adaptation of zk-attest — an existing, working project migrating to Horizen infrastructure. The ZK circuit stays the same; the chain integration changes from Hedera HCS/HTS to Horizen Base L3 with ZEN staking and ZenKinetic privacy gating.
