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.
Works with All curves
Zenroom supports signatures and pairing with most elliptic curves, see the full list here. The curves SECP256K1 (bitcoin, ethereum), BLS381 (ethereum 2.0), ED25519 (Cardano) are all built in by default and can be used together.
Specs
Deterministic execution end-to-end: in-browser, in-memory or distributed to a blockchain. Grants integrity across different platforms.
Tiny library or executable (1MB), low memory usage (600KB~2MB). No external dependencies. Has bindings for most languages.
Written in C (ANSI C99), Zenroom runs on Linux, Windows, Mac, Android, iOS, WebAssembly, integrated Cortex chips and supports Seccomp, see downloads.
