Go Node and SDK for the Neo blockchain.
Overview
NeoGo is a complete platform for distributed application development built on top of and compatible with the Neo project. This includes, but not limited to (see documentation for more details):
- Consensus node
- RPC node & client
- CLI tool
- Smart contract compiler
- Neo virtual machine
- Smart contract examples
- Oracle service
- State validation service
The protocol implemented here is Neo N3-compatible, however you can also find an implementation of the Neo Legacy protocol in 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
Building NeoGo requires Go 1.18+ and make:
make
The resulting binary is bin/neo-go. Notice that using some random revision
from the master branch is not recommended (it can have any number of
incompatibilities and bugs depending on the development stage), please use
tagged released versions.
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
The resulting binary is bin/neo-go.exe.
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.
If you're running a node on Windows, please turn off or configure Windows Firewall appropriately (allowing inbound connections to the P2P port).
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 NeoGo smart contract development workshop that shows some simple contracts that can be compiled/deployed/run using NeoGo 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 wallet is just a NEP-6 file that is used by CLI commands to sign various things. CLI commands are not a direct part of the node, but rather a part of the NeoGo binary, their implementations use RPC to query data from the blockchain and perform any required actions. It's not required to open a wallet on an RPC node (unless your node provides some service for the network like consensus or oracle nodes do).
Monitoring
NeoGo provides Prometheus and Pprof services that can be enabled in the node in order to provide additional monitoring and debugging data.
Configuring any of the two services is easy, add the following section (Pprof
instead of Prometheus if you need that) to the respective config/protocol.*.yml:
Prometheus:
Enabled: true
Addresses:
- ":2112"
where you can switch on/off and define port. Prometheus is enabled and Pprof is disabled by default.
