A complete toolkit for the NEO blockchain, including: - Consensus node (WIP) - [RPC node & client](https://github.com/nspcc-dev/neo-go/tree/master/pkg/rpc/README.md) - [RPC client](https://github.com/nspcc-dev/neo-go/blob/master/pkg/rpc/README.md) - [CLI tool](https://github.com/nspcc-dev/neo-go/blob/master/cli/README.md) - [Smart contract compiler](https://github.com/nspcc-dev/neo-go/blob/master/pkg/vm/compiler/README.md) - [NEO virtual machine](https://github.com/nspcc-dev/neo-go/blob/master/pkg/vm/README.md) # Getting started ## Installation Go: 1.11+ 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` # Contributing Feel free to contribute to this project after reading the [contributing guidelines](https://github.com/nspcc-dev/neo-go/blob/master/CONTRIBUTING.md).
