# Python Blockchain: immutable decentralised data storage A public blockchain and GUI allowing users to store and share information that can't be tampered with or repudiated. The architecture is based on the [IBM Blockchain](https://www.ibm.com/blockchain), however Proof of Work (PoW) is used as a consensus algorithm instead of IBM SE. The PoW structure is adapted from Kansal (2018) with SHA256 as the cryptographic hash function. This software is licensed under the MIT software license (see LICENSE file).

In no event will the author of this software be liable to any party for any damages whatsoever, even if it had been advised of the possibility of damage. ## Requirements - Python 3 ## Install ``` pip3 install flask requests ``` ## Run Open two terminal windows and navigate to the project folder in both. Start the node in one window: ``` python3 node.py ``` Run the GUI in the other window: ``` python3 gui.py ``` You can now view and interact with the blockchain at [http://localhost:5000](http://localhost:5000). Blockchain difficulty can be adjusted in `settings.py` (a higher number means a more expensive computation). For larger-scale implementations, please modify the confirm() function to split transactions appropriately and security audit the code.
