Requirements

Generally, a new Linux operation system is required to run an Elastos node.

User Requirements

This guide is mainly intended for the user who:

Feels comfortable with Linux or similar POSIX shell environment
Has the budget to access a cloud computing service: Amazon EC2, Google Cloud Compute Engine, Microsoft Azure VM
or has space to place a real server

If you are a CRC supernode or install all the components of the Elastos blockchain:

CPU: 2 cores or more
RAM: 32 GB or more
HDD: 200 GB or more
- A solid-state drive (SSD) is a plus but not a must. A hard drive (HDD) should be OK.
- Disk usage will always increase because blockchains are growing. You should monitor your disk to ensure it is big enough to hold all the programs.

A single chain may require fewer resources. For example, you only install the mainchain as a verification node.

If you are a BPoS supernode or have only ELA nodes installed:

OS: Ubuntu 20.04 LTS 64 Bit (Intel x86_64) or newer
- Use Ubuntu because the Elastos blockchain developers use macOS and Ubuntu to develop and test. But it is your freedom of choice of other distributions.
- LTS is better because LTS has a longer product life than the non-LTS version. (See Ubuntu Releases)
- The script prefers a freshly installed OS because it reduces conflicts with the old setup. It is time-consuming to debug such conflicts and do the related support work.

The following ports need to be publicly accessible from anywhere (0.0.0.0/0). For a cloud server, please modify the inbound rules.

If you do not need all the chains, please find a required subset by the chain name.
