Product Information

Description

GNU Taler provides a comprehensive Free Software framework for secure digital transactions, enabling privacy-preserving online payments through cryptographic protocols. It allows users to make purchases without revealing their identity to merchants, while ensuring tax compliance through selective disclosure mechanisms. The system employs blind signatures and zero-knowledge proofs to separate payment authorization from transaction details, preventing financial surveillance and profiling. Key functionalities include anonymous age verification for regulated purchases, sealed-bid auctions where bids remain confidential until selection, and peer-to-peer payment capabilities that maintain user privacy. This infrastructure supports various use cases from e-commerce and digital services to government disbursements, offering both consumer protection and merchant convenience through its open-source architecture.
