# EthSnarks
[](https://gitter.im/ethsnarks?utm_source=share-link&utm_medium=link&utm_campaign=share-link)
Zero-Knowledge proofs are coming to Ethereum and Dapps in 2019!
EthSnarks is a collection of zkSNARK circuits and supporting libraries to use them with Ethereum smart contracts, it aims to help solve one of the biggest problems facing zkSNARKS on Ethereum - cross-platform on desktop, mobile and in-browser, cheap enough to run on-chain, and with algorithms that significantly reduces the time it takes to run the prover.
The notable advantages of using EthSnarks are:
* Reduced cost, 500k gas with 1 input, using [Groth16](https://eprint.iacr.org/2016/260.pdf).
* Prove zkSNARKs in-browser, with WebAssembly and Emscripten
* Linux, Mac and Windows builds
* Solidity, Python and C++ support in one place
* A growing library of gadgets and algorithms
EthSnarks is participating in the Ethereum Foundation's grants program, development will continue full-time and we will be working with companies and developers to help overcome the common challenges and hurdles that we all face. Get in-touch for more information.
**WARNING: EthSnarks is beta quality software, improvements and fixes are made frequently, and documentation doesn't yet exist**
## Examples
* [Miximus - a self-service coin mixer and anonymous transfer method for Ethereum](https://github.com/HarryR/ethsnarks-miximus)
* [Hopper: an Open-Source Mixer for Mobile-friendly private transfers on Ethereum](https://github.com/argentlabs/hopper)
* [Example implementations of ethsnarks](https://github.com/LayerXcom/ethsnarks-examples)
* [An example of a zero-knowledge-proof of a SHA256 pre-image for Ethereum](https://github.com/Ethsnarks/ethsnarks-hashpreimage)
## Building
[](https://travis-ci.org/HarryR/ethsnarks) [](https://ci.appveyor.com/project/harryr/ethsnarks/branch/master)
### Unix Flavours (Linux, OSX, Ubuntu, CentOS etc.)
The following dependencies are required to build Ethsnarks:
* cmake
* g++ or clang++
* gmp
* npm / nvm
Check-out the source-code using:
```bash
git clone git@github.com:HarryR/ethsnarks.git && cd ethsnarks
```
After checking-out the repository you need to install the necessary dependencies, the `Makefile` includes pre-determined rules for different platforms, you need to run this as `root` or an administrator user (i.e. for Brew on OSX):
* `make fedora-dependencies` (CentOS, Fedora, RHEL etc. requires `dnf`)
* `make ubuntu-dependencies` (Ubuntu, Debian etc. requires `apt-get`)
* `make mac-dependencies` (OSX, requires [Homebrew](https://brew.sh/))
Then install the Python dependencies, via Pip, into the local user directory:
* `make python-dependencies`
Then build and test the project:
* `git submodule update --init --recursive`
* `make`
### Windows (64-bit)
Install MSYS2 from https://www.msys2.org/ then open the MSYS2 Shell and run:
```bash
pacman --noconfirm -S make gmp gmp-devel gcc git cmake
git clone git@github.com:HarryR/ethsnarks.git
cd ethsnarks
git submodule update --init --recursive
cmake -E make_directory build
cmake -E chdir build cmake -DCMAKE_BUILD_TYPE=Debug ..
cmake --build build
```
Building under 32-bit MinGW32, MSYS (not MSYS2) and Microsoft Visual Studio may be supported in future depending upon demand, but currently it's probably broken...
### WASM / Browser
WebAssembly, WASM and JavaScript builds are partially supported via [ethsnarks-emscripten](https://github.com/harryr/ethsnarks-emscripten) and [ethsnarks-cheerp](https://github.com/Ethsnarks/ethsnarks-cheerp). The build process is similar, but using the Emscripten and Cheerp toolchains.
# Requests and Contributions
This project aims to help create an ecosystem where a small number of well tested but simple zkSNARK circuits can be easily integrated into your project without having to do all of the work up-front.
If you have any ideas for new components, please [Open an issue](https://github.com/HarryR/ethsnarks/issues/new), or submit a pull request.
# Gadgets
We are surely increasing the range of gadgets, supporting libraries, available documentation and examples; at the moment the best way to find out how to use something is to dig into the code or ask questions via a [new issue](https://github.com/HarryR/ethsnarks/issues/new?labels=question,help%20wanted)
The following gadgets are available
* 1-of-N
* [2-bit lookup table](src/gadgets/lookup_2bit.cpp)
* [3-bit lookup table](src/gadgets/lookup_3bit.cpp)
* [MiMC](https://eprint.iacr.org/2016/492) hash and cipher
* [Poseidon](https://eprint.iacr.org/2019/458.pdf) hash function
* [Miyaguchi-Preneel one-way function](https://en.wikipedia.org/wiki/One-way_compression_function)
* Merkle tree
* SHA256 (Ethereum compatible, full round)
* [Shamir's Secret Sharing Scheme](https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing)
* 'Baby JubJub' twisted Edwards curve
* EdDSA
* Pedersen hash
