neo-go
Go Node and SDK for the NEO blockchain.
# Overview
This project aims to be a full port of the original C# [NEO project](https://github.com/neo-project).
A complete toolkit for the NEO blockchain, including:
- consensus node
- [RPC node & client](https://github.com/CityOfZion/neo-go/tree/master/pkg/rpc/README.md)
- RPC client
- CLI tool
- Smart contract compiler
- NEO virtual machine
# Getting started
## Installation
Install dependencies.
`neo-go` uses [dep](https://github.com/golang/dep) as its dependency manager. After installing `deps` you can run:
```
make deps
```
## How to setup a node
### Docker
Each tagged build is built to docker hub and the `:latest` tag pointing at the latest tagged build.
By default the `CMD` is set to run a node on `testnet`, so to do this simply run:
```bash
docker run -d --name neo-go -p 20332:20332 -p 20333:20333 cityofzion/neo-go
```
Which will start a node on `testnet` and expose the nodes port `20333` and `20332` for the `JSON-RPC` server.
### Building
Build the **neo-go** CLI:
```
make build
```
Quick start a NEO node on the private network. This requires the [neo-privatenet](https://hub.docker.com/r/cityofzion/neo-privatenet/) Docker image running on your machine.
```
make run
```
To run the binary directly:
```
./bin/neo-go node -seed 127.0.0.1:20333,127.0.0.1:20334
```
By default the node will run on the `private network`, to change his:
```
./bin/neo-go node --mainnet
```
Available network flags:
- `--mainnet, -m`
- `--privnet, -p`
- `--testnet, -t`
If you want in-depth customization for your node, there are `yaml` config files for each `network` available in the `config` directory. Those files are automaticly loaded, corresponding the provided `netmode` flag.

## Writing smart contracts in Go
Golang's development is been moved to a separate repository which you can find here [neo-storm](https://github.com/CityOfZion/neo-storm)
