So quickly, before we get lost in the blockchain rabbit hole, what is the difference between a regular database and the blockchain?
Blockchain:
Collects info together in groups.
These groups are “blocks”.
Each block holds a set of information
Each block has “storage capacity”. When these are filled, then the block is closed
Once the block is closed, it’s linked to the previously filled blocks
This forms a chain of data, the blockchain
Database:
Data is stored in “tables” not blocks
This data then makes an irreversible timeline of data
This means unlike blocks, new data cannot become a part of the timeline
Blocks are given timestamps when added to the chain, a database is not like this
