# Zenroom crypto VM [](https://dev.zenroom.org) Zenroom is a **secure language interpreter** of both Lua and its own secure domain specific language (DSL) to execute fast cryptographic operations using elliptic curve arithmetics. The Zenroom VM is very small, has **no external dependency**, is fully deterministic and ready to run **end-to-end encryption** on any platform: desktop, embedded, mobile, cloud micro-services, web browsers. It can be embedded inside applications written in Javascript, Python3, Rust or Golang. **Zencode** is the name of the DSL executed by Zenroom: it is similar to human language and can process large data structures while operating cryptographic transformations and basic logical operations on them. [](http://www.dyne.org) ## Timeline - 2017 - Development started - 2019 - Released version 1.0.0 - 2022 - Released version 2.0.0 (long term support) This software has zero dependencies. If you chose to use it in your project be assured that we intend to support the same code to still run in 20 years from now. Version 3 development started with Quantum Resistant signatures. ## Links Continue to the [developer website](https://dev.zenroom.org/) or Read the [Zencode whitepaper](https://files.dyne.org/zenroom/Zenroom_Whitepaper.pdf) or Visit the [product website](http://zenroom.org/) for a friendly introduction to the love we put in craftsmanship. For many quick running examples visit the [ApiRoom](https://apiroom.net) online IDE powered by Zenroom. **Zenroom is licensed as AGPLv3; we are [open to grant exceptions on a commercial basis](https://forkbomb.eu).** ## Applications Many applications already include Zenroom and use the Zencode language. - [Global Passport Project](https://globalpassportproject.org) - [Keypairoom mnemonic deterministic and private keypairs](https://github.com/LedgerProject/keypairoom) - [Simple Android app to show how to use Zenroom libs](https://github.com/dyne/Zenroom-Android-app) - [Zexec safe remote execution of signed commands](https://github.com/dyne/zexec) - [Micro-service to produce ECDSA signed unix timestamps](https://github.com/dyne/zenstamp) - [Sawroom Transaction Processor for Hyperledger Sawtooth](https://github.com/dyne/sawroom) - [RedRoom Crypto module for Redis](https://github.com/dyne/redroom) - [Lotionroom Tendermint / Cosmos proof of concept with Zenroom](https://github.com/dyne/lotionroom) - [ZenSchnorr API for Schnorr signatures](https://github.com/wires/zenschnorr) - [Great Dane DNSSEC as a AV store for Zenroom](https://github.com/dyne/great-dane) - [Zen-Web-Ext Web extensions encapsulating Zenroom functionality](https://github.com/LedgerProject/zen-web-ext) - [Planetmint by the IPDB foundation](https://ipdb.io) ## Getting Started To quickly try out Zenroom using the Zencode language with some examples navigate to [ApiRoom](https://apiroom.net) and start typing into the browser. The Zenroom VM runs locally in your browser (needs WASM) and [ApiRoom](https://apiroom.net) provides various examples to show operational crypto flows. [ApiRoom](https://apiroom.net) is also an IDE (Integrated Development Environment) and by signing in with a username and password you can save your contracts and download them as a Dockerfile micro-service ready to deploy. ## Build Dependencies: makefile, cmake, zsh, gcc Optional: musl-libc, emscripten for wasm builds Use this command sequence: ``` git clone https://github.com/dyne/zenroom cd zenroom make linux ``` to create the CLI executable in `src/zenroom` ``` make linux-lib ``` to create the shared library in `src/libzenroom-x86_64.so` ``` make ``` to list more available targets ### Meson + Ninja Practical build scripts for GNU/Linux are provided using Meson + Ninja ``` make meson ``` Will produce a `zenroom` executable and a `libzenroom` shared lib in `zenroom/build`. ## License Copyright (C) 2017-2022 Dyne.org foundation Designed and written by Denis "[Jaromil](https://jaromil.dyne.org)" Roio with the help of [Puria](https://github.com/puria) Nafisi Azizi and [Andrea](https://github.com/andrea-dintino) D'Intino.
