Privacy Pools

Privacy pools are the core settlement privacy boundary in PrivChain.

Model

A payment transitions state using:

• commitment insertion,
• nullifier spend protection,
• proof verification,
• deterministic settlement outcome.

Goals

• hide counterparties and amounts by default,
• prevent double spend with nullifiers,
• preserve verifiability for protocol correctness.

Compliance Posture

PrivChain is designed for privacy-first flows with controlled disclosure patterns where required by policy or law.

Implementation Status

Pool architecture is in active implementation and hardening. Public docs intentionally omit exploit-sensitive internals.
