what's OpenCash System?
OpenCash System is a blockchain-based protocol designed as a next-generation digital cash infrastructure. It prioritizes privacy by default for transactions, mimicking the anonymity of physical cash, while incorporating mechanisms for compliance when required by users or regulators. The system features the Ocash Retail Mainnet Alpha, enabling users to launch the Ocash app for private payments that can selectively reveal details for regulatory needs. It integrates cryptographic tools to balance user sovereignty with interoperability in crypto ecosystems.
