This is a full guide to setting up a Ledgerium node on a fresh Linux machine. The blockchain ecosystem is a combination of multiple technologies that come together. It is overwhelming to know that so much has been achieved in a short span. The tech stacks range from (not limited to this list) Docker, NodeJS, GoLang, Yarn, Solidity and supporting Web3.js. Let's start with hardware first.
Minimum Hardware Specifications
  • Operating System: Ubuntu 18.04.2 LTS 64-bit
  • Processor: Intel Core i7 / E3 (4 cores or more)
  • RAM: 8 GB or higher
  • Disk space: 512GB
  • Network Quota: ~100 GB data transfer per month (up + down)


Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.


Docker is a software bundle that uses operating-system-level virtualisation to develop and deliver software in packages called containers. A Docker container is a lightweight, standalone executable package of software code, runtime, system tools, system libraries and settings which enables applications to runs quickly and reliably from one computing environment to another.
The software that hosts the containers is called Docker Engine. Above prerequisites will be installed once you use our one-click setup as explained in next page.
