Primary Node
Verifier. API-dark. No public HTTP surface. Performs ingestion, ZK proof verification, and holds authoritative payment state. Unreachable from agent runtimes or external apps.
How Pakana works
Pakana is a split-architecture private payments infrastructure on Stellar. Verification happens on one side. Public access happens on the other. They do not share a surface.
The split: Primary and Satellite
Satellite
Read-only replica. Public HTTPS surface. Exposes replicated ledger state for dashboards, agent integrations, and developer APIs. Cannot modify state.
One-way replication (read-only)
Stellar Ledger
On-chain BN254/Poseidon proof verification. Protocol 25 primitives. Permanently auditable without Pakana cooperation.
A private payment, step by step
- A client or agent prepares a private-payment action. Stealth address derivation happens client-side.
- Proof generation runs off-chain — including browser-prover paths. No payment detail touches a Pakana server before verification.
- The Primary verifier receives and verifies the proof. Authoritative state is updated. No public API is exposed at this layer.
- Replicated state is available through the Satellite for dashboards, app integrations, and agent runtimes.
Protocol 25 verification primitives
- BN254 elliptic curve
- The curve used for Groth16 proof generation and verification. Supported natively in Stellar Protocol 25 host functions.
- Poseidon hash function
- ZK-friendly hash used in the payment circuit. Runs efficiently inside the BN254 constraint system.
- Groth16 proof system
- The proving system used for private-payment verification. Proofs are compact and fast to verify on-chain.
No custody. No pooled funds.
Pakana does not hold, pool, or have discretionary access to user funds at any layer. The verification workflow is designed so that proof, state, and payment settlement flow through protocol-layer mechanisms, not through a centralized operator account.
