Nethermind's Stellar Private Payments (SPP) brings zero-knowledge privacy to Stellar using Protocol X-Ray, enabling compliant private transactions through Association State Providers (ASPs) for enterprises and users.
This live stream explores Stellar Private Payments (SPP) by Nethermind, an open-source proof of concept that implements zero-knowledge verified private transactions on Stellar. Built on Protocol X-Ray, SPP enables privacy-preserving payments while maintaining compliance through Association State Providers (ASPs) that manage approved and sanctioned users. The speaker explains how private payments work through commitments, merkle trees, and zero-knowledge proofs, covering use cases like private payroll, confidential DEX trading, remittances, institutional treasury management, and CBDCs. SPP differentiates itself from similar projects like Tornado Cash and Railgun by prioritizing compliance-first design, combining ZCash's cryptographic model with Stellar's fast and inexpensive payment rails plus Soroban smart contracts.
