Homework on provenance :
01 : How does blockchain enable digital provenance?
By being a a public distributed ledger, whereby many individually keep track of every data exchange.
“Only data can be added to the blockchain but not removed”. By checking the ledger in a decentralised way.
The majority will always be truthful because of incentives. And therefore one cannot add false data to the blockchain. This data / transaction would be rejected by the majority of other nodes.
02 : Why doesn’t a normal database bring the same provenance?
Because a normal database is controlled by a central party. And that party can add and redact data from its database at will. Therefore you need to trust the administrator of said database.
With Blockchain on the other hand you do not need to trust a single central party. Instead the collective decides the truth.
03 : Why is digital provenance such a great benefit to many businesses?
Because being able to trace each addition to the ledger provides for a very good transparency. Being open and public, everyone can check what is happening.
Real time auditing can be a very useful application in various industry’s.
