kandi X-RAY | QRL Summary
Python-based blockchain ledger utilizing hash-based one-time merkle tree signature scheme (XMSS) instead of ECDSA. Proof-of-work block selection via the cryptonight algorithm. Future transition to POS with signed iterative hash chain reveal scheme which is both probabilistic and random (Hash-based signatures means larger transactions (3kb 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). Currently XMSS/W-OTS+ are natively supported with extensible support for further cryptographic schemes inbuilt.

I developp on colab and i save my code to create my own module qrl.py on drive but in my qrl.y i use !pip install deplacy and import numpy.
if i try to import the module i have the error following

Install QRL
You can use QRL like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
