# 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](docs/consensus.md)
|
|
- [RPC node & client](docs/rpc.md)
|
|
- [CLI tool](docs/cli.md)
|
|
- [Smart contract compiler](docs/compiler.md)
|
|
- [NEO virtual machine](docs/vm.md)
|
|
|
|
This branch (**master**) is under active development now (read: won't work
|
|
out of the box) and aims to be compatible with Neo 3. For the current stable
|
|
version compatible with Neo 2 please refer to the [**master-2.x**
|
|
branch](https://github.com/nspcc-dev/neo-go/tree/master-2.x) and releases
|
|
before 0.80.0 (**0.7X.Y** track). Releases starting from 0.90.0 will contain
|
|
Neo 3 code.
|

# Getting started
|
|
|
|
## Installation
|
|
|
|
Go: 1.12+
|
|
|
|
Install dependencies.
|
|
|
|
`neo-go` uses [GoModules](https://github.com/golang/go/wiki/Modules) as dependency manager:
|
|
|
|
```
|
|
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
|
|
```
|
|
|
|
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`
|
|
|
|
#Developer notes
|
|
Nodes have such features as [Prometheus](https://prometheus.io/docs/guides/go-application) and
|
|
[Pprof](https://golang.org/pkg/net/http/pprof/) in order to have additional information about them for debugging.
|
|
|
|
How to configure Prometheus or Pprof:
|
|
In `config/protocol.*.yml` there is
|
|
```
|
|
Prometheus:
|
|
Enabled: true
|
|
Port: 2112
|
|
```
|
|
where you can switch on/off and define port. Prometheus is enabled and Pprof is disabled by default.
