# Overview
|
|
|
|
NeoGo is a complete platform for distributed application development built on
|
|
top of and compatible with the [Neo project](https://github.com/neo-project).
|
|
This includes, but not limited to (see documentation for more details):
|
|
|
|
- [Consensus node](docs/consensus.md)
|
|
- [RPC node & client](docs/rpc.md)
|
|
- [CLI tool](docs/cli.md)
|
|
- [Smart contract compiler](docs/compiler.md)
|
|
- [Neo virtual machine](docs/vm.md)
|
|
- [Smart contract examples](examples/README.md)
|
|
- [Oracle service](docs/oracle.md)
|
|
- [State validation service](docs/stateroots.md)
|
|
|
|
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](https://github.com/nspcc-dev/neo-go/tree/master-2.x) 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](https://github.com/nspcc-dev/neo-go/releases), use a Docker image (see
|
|
[Docker Hub](https://hub.docker.com/r/nspccdev/neo-go) for various releases of
|
|
NeoGo, `:latest` points to the latest release) or build yourself.
|
|
|
|
### Building
|
|
|
|
Building NeoGo requires Go 1.17+ 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](https://osdn.net/projects/mingw/). 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](docs/consensus.md).
|
|
|
|
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:
|
|
|
|
```bash
|
|
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](https://sync.ngd.network/), 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](docs/consensus.md).
|
|
|
|
## Smart contract development
|
|
|
|
Please refer to [NeoGo smart contract development
|
|
workshop](https://github.com/nspcc-dev/neo-go-sc-wrkshp) 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](docs/compiler.md).
|
|
|
|
Refer to [examples](examples/README.md) for more Neo smart contract examples
|
|
written in Go.
|
|
|
|
## Wallets
|
|
|
|
NeoGo wallet is just a
|
|
[NEP-6](https://github.com/neo-project/proposals/blob/68398d28b6932b8dd2b377d5d51bca7b0442f532/nep-6.mediawiki)
|
|
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](https://prometheus.io/docs/guides/go-application) and
|
|
[Pprof](https://golang.org/pkg/net/http/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.
