It is intended to serve as a reference implementation of privacy pools for Stellar. The code has not yet been audited and should not be used in production environments with real assets as of now. The security hardening work is planned. Expect breaking changes and necessity to clear your local storage for the demo app/cli until the first stable release. A privacy-preserving payment system for the Stellar network using zero-knowledge proofs. This implementation enables users to deposit, transfer, and withdraw tokens while maintaining transaction privacy through Groth16 proofs. The system incorporates Association Set Provider (ASPs) as a control mechanism to provide illicit activity safeguards through association sets. ASPs maintain membership and non-membership Merkle trees that allow proving whether specific deposits are part of approved or blocked sets, enabling pool operators to enforce administrative controls without compromising user privacy. Features - Private Payments : Deposit, transfer, and withdraw tokens without revealing transaction amounts or sender/receiver relationships - Zero-Knowledge Proofs : Groth16 (over BN254) proofs generated via Circom circuits. - Administrative Controls : ASP-based membership and non-membership proofs for illicit activity safeguards - Browser-Based Proving : Client-side proof generation using WebAssembly - Stellar Integration : Built on Soroban smart contr","default_branch":null,"files":null,"tree":[],"storefront":"/r/NethermindEth","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/NethermindEth/stellar-private-payments/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
