QRL Node Requirements

In order to run a QRL node, the computer must meet some basic requirements. This doc will cover these minimum requirements and give some known working examples.

The main QRL node software is developed in python, though it relies on some code that is not yet ported to Windows. For now the QRL node will need to be ran from a Linux/Unix system.

Hardware Requirements

These are the basic hardware requirements to run a QRL Node.


An AES-NI enabled processor is required for cryptographic functions of the system. AES provides XXXXX while AVX2 is used by the keccak library for hashing functions.

Compatibility Check

Using the grep command, run the following from a UNIX shell to validate if your processor supports AES-NI and avx2

grep -m1 -o -E 'avx|aes' /proc/cpuinfo

Alternatively, read the file manually or use lscpu

lscpu |grep -E  'aes|avx'

The prompt will show compatible support if available.

HDD Storage

Enough storage is required for the current () and future chain growth. The node software will sync each block from the genesis block on June 2018 till current block height as agreed across the network.

Reliable Network Connection

The node will send information and request information from other nodes in the network periodically. This is critical to the functionality of the node. Each node must keep up to date with each other in consensus to the current blockheight.

Externally Reachable Node

Advanced configuration is required for the node to validate blocks and share block information via the p2p network. Additional ports need to be reachable and a static IP address is preferred

Modern 64 bit Processor

A newer processor is required as listed above to support AES-NI.

Software Requirements

  • Python 3.6 or later
