Python-based blockchain ledger utilising hash-based one-time merkle tree signature scheme (XMSS) instead of ECDSA. Proof-of-stake block selection via a signed iterative hash chain reveal scheme which is both probabilistic and random (https://github.com/theQRL/pos).
Hash-based signatures means larger transactions (6kb per tx, binary), longer keypair generation times and the need to record 'state' of transactions as each keypair can only be used once safely. Merkle tree usage enables a single address to be used for signing numerous transactions (up to 2^13 computationally easily enough). Transactions have an incremented nonce to allow wallets to know which MSS keypair to use - currently XMSS/W-OTS+ are natively supported.

You are welcome to install the alpha version and join the testnet. Be aware that work is in progress and there might be frequent breaking changes.
Ensure your apt sources are up to date and install dependencies
sudo apt update
sudo apt -y install swig3.0 python3-dev python3-pip build-essential cmake pkg-config libssl-dev libffi-dev
To get the source and start the node, use the following:
git clone https://github.com/theQRL/QRL.git
cd QRL/
sudo pip3 install -r requirements.txt

Debian has some issues in old packages, so you need to install some backports.
Debian does not have sudo
by default, if you have not installed sudo
, the use su
and later do not forget to exit
.
Do NOT run the node as root.
The following lines show [sudo]
as optional. Adjust accordingly.
echo "deb http://ftp.debian.org/debian jessie-backports main" | [sudo] tee -a /etc/apt/sources.list
[sudo] apt-get update
[sudo] apt-get -t jessie-backports install cmake swig3.0

If you dont have brew yet, we think you should :) Install brew following the instructions here: https://brew.sh/
Now install some dependencies
brew update
brew install cmake python3 swig boost
To get the source and start the node, use the following:
git clone https://github.com/theQRL/QRL.git
cd QRL/
sudo pip3 install -r requirements.txt
python3 start_qrl.py
Install dependencies
sudo apt update
sudo apt -y install swig3.0 python3-dev build-essential cmake ninja-build libboost-random-dev libssl-dev libffi-dev
sudo pip3 install -U setuptools pip
To get the source and start the node, use the following:
git clone https://github.com/theQRL/QRL.git

Windows support in the current version is limited. An alternative is to use an Ubuntu VM (virtualbox). Docker containers are not working wel in Windows at the moment
We are working on a solution to native Windows support
