MIMic blockchain server

Implementation of RTBF-Blockchain server with 3 kinds of transactions
This class should be called RTBF-Blockchain

what we mean by editable is that we can edit, delete the data inside the block

we should implement 3 classes inside the blockchain these classes is for the transaction

First we will user the regular hash function SHA256 to generate immutable data that can't be deleted we will save payment data inside these transactions.

Second we will implement Editable Transaction :// The hash id for this is based on MAP-ABCH that will give us the key to edit
These transaction will have the hash idea that can be edit : Edit means we can make two transaction having the same hash ID
So when we want to edit we will create another transaction say T' that will replace the transaction saved T

Third is the RTBF transaction: what we mean by RTBF is Right To Be Forgotten which will allow these transaction to be deleted. After delete we should show the previous transaction numbers and the current transaction numbers which will be n-1
