Homework on Provenance - Answers
How does blockchain enable digital provenance?
Transactional activity is recorded forever in the blockchain. The example of the imutibility of a viking runestone is a good one. Activity is recorded in the blockchain, can be added to but not subtracted from. It is held within the distributed ledger among so many nodes verifying and confirming the accuracy. It is trustless.
Why doesn’t a normal database bring the same provenance?
Our traditional databases are owned by someone, a person, corporation or government entity. These entities are subject to corruption as are the data contained within and can be compromised intentionally or inadvertently. Auditing is necessary to ensure accuracy, trust is necessary and is sometimes not deserved.
Why is digital provenance such a great benefit to many businesses?
It calls truth to the table and this should be the biggest benefit. The supply chain of a produced item
is traced to the source. This should be a good thing in substantiating production and in giving
transparency to the public.
