New Decentralized Asset-Transfer System Ensures Privacy and Compliance

/ 1 min read

🪙 New decentralized asset-transfer system ensures full privacy and regulatory compliance. Researchers have developed a decentralized asset-transfer system that guarantees complete privacy for transactions, allowing only the issuer and recipient to know the transaction details. The system operates without consensus or synchrony assumptions, making it responsive to actual network speeds. Each transaction generates a consumable coin with a non-interactive zero-knowledge proof (NIZK) to verify sufficient funds without disclosing identities or amounts. Additionally, it includes a regulatory enforcement mechanism to manage transfer limits and address restrictions while maintaining privacy. The implementation, called Paxpay, demonstrates superior performance compared to previous models that offered limited privacy or required network synchrony. This innovation balances privacy, responsiveness, regulatory enforcement, and performance effectively.
