Go Node and SDK for the NEO blockchain.
Overview
This project aims to be a full port of the original C# Neo project. A complete toolkit for the NEO blockchain, including:
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 and releases before 0.80.0 (0.7X.Y track). Releases starting from 0.90.0 contain Neo 3 code (0.90.0 being compatible with Neo 3 preview2).
Getting started
Installation
Go: 1.13+
Install dependencies.
neo-go
uses GoModules 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:
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
Running
Quick start a NEO node on the private network. This requires the 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
Importing mainnet/testnet dump files
If you want to jump-start your mainnet or testnet node with chain archives provided by NGD follow these instructions (when they'd be available for 3.0 networks):
$ wget .../chain.acc.zip # chain dump file
$ unzip chain.acc.zip
$ ./bin/neo-go db restore -m -i chain.acc # for testnet use '-t' flag instead of '-m'
The process differs from the C# node in that block importing is a separate mode, after it ends the node can be started normally.
Smart contract development
Please refer to neo-go smart contract development workshop that shows some simple contracts that can be compiled/deployed/run using neo-go compiler, SDK and private network. For details on how Go code is translated to Neo VM bytecode and what you can and can not do in smart contract please refer to the compiler documentation.
Developer notes
Nodes have such features as Prometheus and 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.
