Lisk Core

License: Apache 2.0 GitHub tag (latest by date) GitHub repo size DeepScan grade GitHub issues GitHub closed issues

Lisk is a next-generation crypto-currency and decentralized application platform, written entirely in JavaScript. The official documentation about the whole ecosystem can be found in https://lisk.com/docs.

Lisk Core is the program that implements the Lisk Protocol. In other words, Lisk Core is what every machine needs to set-up to run a node that allows for participation in the network.

This document details how to install Lisk Core from source and from npm registry, but there are two other ways to participate in the network: binaries and Docker images. If you have satisfied the requirements from the Pre-Installation section, you can jump directly to the next section Installation Steps.

Command Topics

Managing Lisk Node

To start a Lisk Core node as a background process, we recommend using a process management tool, such as PM2.

Example using PM2

npm i -g pm2
pm2 start "lisk-core start" --name lisk-mainnet
pm2 status
pm2 logs lisk-mainnet

For a more advanced options refer to PM2 documentation.

Configuring Lisk Node

lisk-core start supports flag and environment variable options to configure a node.

Also, custom configuration through JSON file is available through the --config, -c flag.

Example

With custom config file ./custom-config.json below

{
  "network": {
    "port": 5000,
  },
  "transactionPool": {
    "maxTransactions": 8096,
    "maxTransactionsPerAccount": 1024,

  "forging": {

    }],
  },
  "plugins": {
    "httpApi": {
      "port": 7000,

  },
}

Running a command will overwrite the default config and use the specified options.

lisk-core start -n devnet -c ./custom-config.json

For a more detailed understanding of configuration read this online documentation.

Tests

Automated tests

All automated tests will run with the below command.

npm test

Running a local development node

In order to run a node for a local test, in a root folder of lisk-core, run below command.

./bin/run start -n devnet --data-path ./devnet-data --port 3333 --api-ws --enable-http-api-plugin --http-api-plugin-port 3334 --enable-forger-plugin

This command will start a lisk-core node using data path ./devnet-data with HTTPAPI and Forger Plugins. Data on the node can be obtained by commands like

./bin/run node:info --data-path ./devnet-data
./bin/run block:get 3 --data-path ./devnet-data
