Zenroom

Zenroom

Crypto VM for database and blockchain

Zenroom is a tiny and portable virtual machine that integrates in any application to authenticate and restrict access to data and execute human-readable smart contracts.

Make cryptography easy

Clearly separate the workflow of programmers, cryptographers and privacy analysts: facilitate reviews, updates and distributed architecture design.

Features

Perform Elliptic Curve Pairing as well public/private asymmetric key cryptography, much faster than RSA

Attribute based credentials (ABC) and zero knowledge proof (ZKP)  based on Coconut.

Executes smart contracts in Lua or in Zencode, a plain English-like Domain Specific Language.

Deterministic execution of smart contracts on any database or blockchain. Grants integrity across all platforms.

Tiny library or executable (1MB), low memory usage (down to 64KB), with no external dependencies. Language bindings: Js, Py, Go …

Runs on any platform, including Linux, Windows, Mac, Android, iOS, WebAssembly (in browser) and integrated Cortex chips.
