2018-03-25 14:03:38 +00:00
This project aims to be a full port of the original C# [NEO project ](https://github.com/neo-project ).
2018-02-01 17:40:04 +00:00
A complete toolkit for the NEO blockchain, including:
2019-08-21 16:30:21 +00:00
- Consensus node (WIP)
2019-08-21 17:31:48 +00:00
- [RPC node & client ](https://github.com/nspcc-dev/neo-go/tree/master/pkg/rpc/README.md )
2019-08-21 16:30:21 +00:00
- [RPC client ](https://github.com/nspcc-dev/neo-go/blob/master/pkg/rpc/README.md )
2019-09-02 13:43:44 +00:00
- [CLI tool ](https://github.com/nspcc-dev/neo-go/blob/master/cli/README.md )
2019-08-21 16:30:21 +00:00
- [Smart contract compiler ](https://github.com/nspcc-dev/neo-go/blob/master/pkg/vm/compiler/README.md )

# Getting started
2018-01-31 11:51:02 +00:00
2018-03-25 14:03:38 +00:00
## Installation
2018-01-31 11:51:02 +00:00
2019-09-10 17:30:54 +00:00
Go: 1.12+
2019-08-26 13:58:24 +00:00
2018-03-25 14:03:38 +00:00
Install dependencies.
2018-01-28 18:37:03 +00:00
2019-08-26 13:58:24 +00:00
`neo-go` uses [GoModules ](https://github.com/golang/go/wiki/Modules ) as dependency manager:
2018-02-01 17:40:04 +00:00
2018-02-01 18:06:17 +00:00
```
make deps
```

## How to setup a node
2018-04-16 08:41:23 +00:00
### 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
2018-02-01 18:06:17 +00:00
Build the **neo-go** CLI:
```
make build
```
2018-02-01 17:40:04 +00:00
2018-03-25 14:03:38 +00:00
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.
2018-01-28 18:37:03 +00:00
2018-02-01 17:40:04 +00:00
```
2018-03-03 07:16:05 +00:00
make run
2018-02-01 17:40:04 +00:00
```
2018-01-28 18:37:03 +00:00
2018-03-03 07:16:05 +00:00
To run the binary directly:
2018-02-01 17:40:04 +00:00
```
2019-09-02 13:43:44 +00:00
./bin/neo-go node
2018-02-01 17:40:04 +00:00
```
2018-02-01 08:00:42 +00:00
2018-03-25 14:03:38 +00:00
By default the node will run on the `private network` , to change his:
2018-02-01 08:00:42 +00:00
2018-02-01 17:40:04 +00:00
```
2018-03-25 14:03:38 +00:00
./bin/neo-go node --mainnet
2018-02-01 17:40:04 +00:00
```
2018-02-01 08:00:42 +00:00
2018-03-25 14:03:38 +00:00
Available network flags:
- `--mainnet, -m`
- `--privnet, -p`
- `--testnet, -t`
