Python Script Editing / Blockchain

Hi,

I'm looking for some help ASAP with a Python Script I have as I need to adapt and enhance it.

This script emulates a blockchain, based on "money" transactions and holds it within the terminal only.

I need help to add a few features into this script.

Change the use of the "blockchain" to editing/updating Medical Records, rather than sending money

Create a set of predefined user names that can add and receive to the blockchain e.g. It asks for sender name, and if the name entered is not on a predefined list of users then it will not add data to the blockchain.

Print and save the transactions of the block to an external file, with the hashes. Preferable this would print to a .CSV or JSON file. This would essentially act as a ledger.
