Python-based blockchain ledger utilising hash-based one-time merkle tree signature scheme (XMSS) instead of ECDSA. Proof-of-work block selection via the cryptonight algorithm. Late 2018 planned transition to POS with 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.

get an error with

Windows support in the current version is limited. An alternative is to use an Ubuntu VM (virtualbox), or install Ubuntu using the Linux Subsystem for Windows. Docker containers are not working well in Windows at the moment
It is possible to run a QRL node using an Ubuntu Bash shell through the Linux Subsystem for Windows. Follow these instructions to install Ubuntu using Linux Subsystem, start the Ubuntu bash shell, and then follow the previous instructions on setting up QRL on Ubuntu.
We are working on a solution to native Windows support
