go-dvote

This repository contains a set of libraries and tools for the Vocdoni decentralized backend infrastructure, as described in the documentation.

A good summary of the whole Vocdoni architecture can be found in the blog post technical overview v1.

Vocdoni

Vocdoni is a universally verifiable, censorship-resistant, and anonymous self sovereign governance system, designed with the scalability and ease-of-use to support either small/private and big/national elections.

Our main aim is a trustless voting system, where anyone can speak their voice and where everything can be audited. We are engineering building blocks for a permissionless, private and censorship resistant democracy.

We intend the algorithms, systems, and software that we build to be a useful contribution toward making violence in these cryptonetworks impossible by protecting users privacy with cryptography. In particular, our aim is to provide the necessary tooling for the political will of network participants to translate outwardly into real political capital, without sacrificing privacy.

dvotenode

The dvotenode is the main tool of go-dvote, it contains all the required features for making the decentralized Vocdoni backend possible.

Currently dvotenode can operate in three modes:

gateway mode provides an entry point to the P2P networks for the clients (APP or Web), it uses most of the components from go-dvote. Detailed information can be found here
miner mode provides a block validation node (full node) of the Vochain (Tendermint based blockchain for voting). Detailed information can be found here
oracle mode provides a bridge between Ethereum and the Vochain

One of the design primitives of go-dvote is to run everything as a single daemon in order to have complete control over the components and avoid local RPC or IPC connections. So unlike other projects, go-dvote uses go-ethereum, go-ipfs and tendermint as GoLang libraries.

In addition, go-dvote is currently pure GoLang code, so generating a static and reproducible binary that works on most of the Linux hosts (and probably MacOS) without any dependence is possible.

For running dvotenode in gateway mode, 8GB of ram is recommended (4GB works but it is risky).

Status

Compile and run

Compile from source in a golang environment (Go>1.17 required):

git clone https://go.vocdoni.io/dvote.git
cd go-dvote
go build ./cmd/dvotenode
./dvotenode --help

Docker

You can run go-dvote as a standalone container with a docker script (configuration options can be changed in file dockerfiles/dvotenode/env):

dockerfiles/gateway/dockerlaunch.sh

All data will be stored in the shared volume run.

Docker compose

Standalone components can be built and run as the examples:

Gateway (default)

cd dockerfiles/dvotenode
docker-compose build
docker-compose up -d

Miner

cd dockerfiles/dvotenode
docker-compose build
docker-compose -f docker-compose.miner.yml up -d

The test suite is an all-in-one compose file to bootstrap a minimal testing testing environment. To do a voting process test, follow the examples mentioned in the included README:

cd dockerfiles/testsuite
cat README.md
