Most systems today use a normal database.
š Think of it like this:
One owner controls the data
Changes can be made quietly
You must trust the authority
Now compare that with blockchain.
š Blockchain works differently:
Data is shared across many computers
Every change is visible and recorded
No single person controls it
Simple comparison:
Normal database ā control-based
Blockchain ā proof-based
In a database, trust comes first.
In blockchain, verification comes first.
Thatās why blockchain is harder to manipulate and easier to verify.
š Tomorrow: How blockchain stays secure.
Point to Ponder:
If data affects our lives, should it belong to one owner or many?
