# Overview
|
|
|
|
> This project is currently in **alpha** and under active development.
|
|
|
|
## Project Goals
|
|
|
|
Full port of the original C# [NEO project](https://github.com/neo-project).
|
|
A complete toolkit for the NEO blockchain, including:
|
|
|
|
- Full consensus node
|
|
- Full RPC node
|
|
- RPC client
|
|
- CLI tool
|
|
- Smart contract compiler
|
|
|
|
## Current State
|
|
|
|
The project will exist out of the following packages:

# Getting Started
|
|
|
|
## Node
|
|
|
|
Install dependencies, this requires [dep](https://github.com/golang/dep):
|
|
|
|
```
|
|
make deps
|
|
```
|
|
|
|
Build the **neo-go** CLI:
|
|
|
|
```
|
|
make build
|
|
```
|
|
|
|
Currently, there is a minimal subset of the NEO protocol implemented.
|
|
To start experimenting make sure you a have a private net running on your machine.
|
|
If you dont, take a look at [docker-privnet-with-gas](https://hub.docker.com/r/metachris/neo-privnet-with-gas/).
|
|
|
|
Start a NEO node:
|
|
|
|
```
|
|
make run
|
|
```
|
|
|
|
You can add multiple seeds if you want:
|
|
|
|
```
|
|
make run -e SEEDS="127.0.0.1:20333,127.0.01:20334"
|
|
```
|
|
|
|
By default the server will currently run on port 3000, for testing purposes.
|
|
You can change that by setting the tcp flag:
|
|
|
|
```
|
|
make run -e PORT="1337"
|
|
```
|
|
|
|
To run the binary directly:
|
|
|
|
```
|
|
./bin/neo-go node -seed 127.0.0.1:20333 -tcp 1337
|
|
```
|
|
|
|
## RPC
|
|
|
|
If you want your node to also serve JSON-RPC, you can do that by setting the following flag:
|
|
|
|
```
|
|
./bin/neo-go node -rpc 4000
|
|
```
|
|
|
|
In this case the server will accept and respond JSON-RPC on port 4000.
|
|
Keep in mind that currently there is only a small subset of the JSON-RPC implemented.
|
|
Feel free to make a PR with more functionality.

|
## Smart Contracts
|
|
> In depth documentation about the neo-go compiler and smart contract examples can be found inside the [compiler package](https://github.com/CityOfZion/neo-go/tree/master/pkg/vm/compiler).
|
|
|
|
### Compile a smart contract
|
|
|
|
```
|
|
./bin/neo-go contract compile -i mycontract.go
|
|
```
|
|
|
|
By default the filename will be the name of your .go file with the .avm extension, the file will be located in the same directory where you called the command from. If you want another location for your compiled contract:
|
|
|
|
```
|
|
./bin/neo-go contract compile -i mycontract.go --out /Users/foo/bar/contract.avm
|
|
```
|
|
|
|
### Debugging your smart contract
|
|
You can dump the opcodes generated by the compiler with the following command:
|
|
|
|
```
|
|
./bin/neo-go contract opdump -i mycontract.go
|
|
```
|
|
|
|
This will result in something like this:
|
|
|
|
```
|
|
INDEX OPCODE DESC
|
|
0 0x52 OpPush2
|
|
1 0xc5 OpNewArray
|
|
2 0x6b OpToAltStack
|
|
3 0x 0 OpPush0
|
|
4 0x6c OpFromAltStack
|
|
5 0x76 OpDup
|
|
6 0x6b OpToAltStack
|
|
7 0x 0 OpPush0
|
|
8 0x52 OpPush2
|
|
9 0x7a OpRoll
|
|
10 0xc4 OpSetItem
|
|
```
