status-go/config

Introduction

This document describes the available options in the JSON config for status-go.

The structure of the JSON config is defined in the params/config.go file, which also contains detailed comments on meaning of each option. The NodeConfig struct defines the general configuration keys at the root of the JSON file.

If the descriptions of any options are too vague feel free to open an issue.

Example config files can be viewed in the config/cli folder.

Important Sections

The JSON config is separated into several sections. The most important ones are listed below.

NodeConfig

The root of the JSON configuration.

An example of most important settings would include:

{
    "NetworkID": 1,
    "DataDir": "/tmp/status-go-data",
    "NodeKey": "123qwe123qwe123qwe123",
    "Rendezvous": false,
    "NoDiscovery": false,
    "ListenAddr": "0.0.0.0:30303",
    "RegisterTopics": ["whispermail"]
}

If you'd want to enable JSON RPC port you'd need:

{
    "HTTPEnabled": true,
    "HTTPHost": "0.0.0.0",
    "HTTPPort": 8545,
    "APIModules": "eth,net,web3,admin"
}

In order to adjust logging settings you'd need:

{
    "LogFile": "/var/log/status-go.log",
    "LogLevel": "INFO",
    "LogMaxSize": 200,
    "LogMaxBackups": 5,
    "LogCompressRotated": true
}

Valid LogLevel settings are: ERROR, WARN, INFO, DEBUG, TRACE

WakuConfig

If you want your node to relay Waku(modified Whisper) protocol messages you'll want to include this:

{
    "WakuConfig": {
        "Enabled": true,
        "EnableMailServer": true,
        "DataDir": "/tmp/status-go-data/waku",
        "MailServerPassword": "status-offline-inbox"
    }
}

The MailServerPassword is used for symmetric encryption of history requests.

By default it will use leveldb embedded database. To use postgres instead you need to add this to your config:

{
    "DatabaseConfig": {
      "PGConfig": {
        "Enabled": true,
        "URI": "postgres://user:password@host:port?options"
      }
    }
}

NOTE: The default password used by Status App and our mailservers is status-offline-inbox.

ClusterConfig

This config manages what peers and bootstrap nodes your status-go instance connects when it starts.

{
  "ClusterConfig": {
    "Enabled": true,
    "Fleet": "eth.prod",
    "BootNodes": [
      "enode://345ert345ert@23.45.67.89:30404"
    ],
    "TrustedMailServers": [
      "enode://qwe123qwe123@98.76.54.32:30504"
    ],
    "StaticNodes": [
      "enode://123qwe123qwe@12.34.56.78:30305"
    ]
  }
}

BootNodes help the status-go instance find peers. They are more important to have than StaticNodes or TrustedMailServers, which are just statically added peers on start.
