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:
- Consensus node
- RPC node & client
- CLI tool
- Smart contract compiler
- NEO virtual machine
- Smart contract examples
- Oracle service
- State validation service
This branch (master) is Neo N3-compatible. For the current Legacy-compatible version please refer to the master-2.x branch and releases before 0.80.0 (0.7X.Y track).
Getting started
Installation
NeoGo is distributed as a single binary that includes all the functionality
provided (but smart contract compiler requires Go compiler to operate). You
can grab it from releases
page, use a Docker image (see
Docker Hub for various releases of
NeoGo, :latest points to the latest release) or build yourself.
Building
To build NeoGo you need Go 1.17+ and make:
make build
The resulting binary is bin/neo-go.
Building on Windows
To build NeoGo on Windows platform we recommend you to install make from MinGW
package. Then, you can build NeoGo with:
make build
The resulting binary is bin/neo-go.exe.
We also recommend you to switch the Windows Firewall off for further NeoGo node run.
Running a node
A node needs to connect to some network, either local one (usually referred to
as privnet) or public (like mainnet or testnet). Network configuration
is stored in a file and NeoGo allows you to store multiple files in one
directory (./config by default) and easily switch between them using network
flags.
To start Neo node on a private network, use:
./bin/neo-go node
Or specify a different network with an appropriate flag like this:
./bin/neo-go node --mainnet
Available network flags:
--mainnet, -m--privnet, -p--testnet, -t
To run a consensus/committee node, refer to consensus documentation.
Docker
By default, the CMD is set to run a node on privnet. So, to do this, simply run:
docker run -d --name neo-go -p 20332:20332 -p 20331:20331 nspccdev/neo-go
Which will start a node on privnet and expose node's ports 20332 (P2P
protocol) and 20331 (JSON-RPC server).
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:
$ 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.
Running a private network
Refer to consensus node documentation.
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 a private network. For details on how Go code is translated to Neo VM bytecode and what you can and can not do in a smart contract, please refer to the compiler documentation.
Refer to examples for more NEO smart contract examples written in Go.
Wallets
NeoGo differs substantially from C# implementation in its approach to wallets. NeoGo wallet is just a NEP-6 file that is used by CLI commands to sign various things. There is no database behind it, the blockchain is the database and CLI commands use RPC to query data from it. At the same time, it's not required to open a wallet on an RPC node to perform various actions (unless your node provides some service for the network like consensus or oracle nodes do).
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.
