Reallu useful article but one question.
How is data stored in a block exactly. For example if we consider a medical health record system, do many health records are stored in one block or one medical record is only stored in one block. If there can be many records in one block, does one record (transaction) has a unique key or hash.
And if we need to update one record how can it happen?
