Crypto smart-contract executor
Zenroom is a tiny secure execution environment that integrates in any platform and application, even on a chip or a web page. It can authenticate, authorize access and execute human-readable smart contracts for blockchains, databases and much more. It helps to develop cryptography keeping it simple, understandable and maintainable.
