By storing information which is accessible to all participants in the network. I also enables to add information by all participants, but not to erase or change it.
-
Normal database is centralized and therefore there is a risk of tampering with it and doesn’t have the same level of trust.
-
It enables tracking of origin of items. It helps organizing tasks and to communicate in complex organizations. I also stores information about items, which is accessible and easily reviewable by all participants.

Blockchain is a decentralised data base where every transaction can be traced.
-
Because databases are governed this one isn’t. No transaction can be removed or erased.
-
Because you can see every detail of all invoices in real time and it’s open to the public.

1 If you put some kind of data on blockchain that information remain in blockchain forever. Nobody can modify or erase and everybody can read that information. What
happen in Blockchain stays in Blockchain 
2 You have to trust that database and the people who create it, they can erase or modify it.
3 The blockchain Technology help businesses to improve the quality of services or products by implementing Provenance, help them by more productive and efficient, and gain more trust from customers

- transparency and immediate verifiability of transactions, many layers of redundancy in verification public.
- because most are controlled by someone and it is ‘take my word for it’ kind of thing. Many of these other databases are private and cloaked.
- A lot of energy can be saved in trying to audit systems in order to trust transactions. With a proven provenance system like blockchain, these efforts are automatic with trust built in… If a supplier says they included a certain amount of material in a product, this can instantly be seen.

Homework on Provenance - Questions
- How does blockchain enable digital provenance?
- Why doesn’t a normal database bring the same provenance?
- Why is digital provenance such a great benefit to many businesses?
Answers
-
By acting as a Digital Stone, it allows all transactions to be recorded (date, place, time)
and is irremovable from the blockchain giving it complete track-ability. -
Physical fiat relies on trust of the spender to report the transaction and digital fiat is
limited as it has to be manually audited and verified by a person- This consumes a large
amount of time and effort , this process is vulnerable to mistakes and manipulation. -
It allows for trustless business deals and transaction, giving business confidence and
transparency. This should lead to higher quality processes.
Don’t trust… Verify!

- How does blockchain enable digital provenance?It allows for real time auditing through a public ledger (can be encypted) A trustless system removes trust from transactions as proof is verified within the ledger (blockchain)
- Why doesn’t a normal database bring the same provenance?Data within a normal ralational database can be changed, deleted or lost through hardware malfunction. Data on the blockchain cannot be changed, lost or deleted and is always verifiable.
- Why is digital provenance such a great benefit to many businesses?
Digital provenance can offer real time auditing, track or trace where goods or services have originated

How does blockchain enable digital provenance?
By being immutable and easily verifiable.
Why doesn’t a normal database bring the same provenance?
Normal databases are editable and most often centralized. They are also inefficient and one would probably need several relational databases to enable some level of digital provenance which would basically add to these problems exponentially.
Why is digital provenance such a great benefit to many businesses?
Highly efficient, cost effective, reliable and eliminates the need for “blind” trust as data can simply be verified by anyone at any time.
(hope I did well there, but please someone correct this n00B!)

Due to its inherent tracking and tracing technology which is also decentralized, blockchain and be a great source of auditing and real time transaction history.
-
A normal database is not a public ledger and therefore is not open to the same open information as provided by a public ledger.
-
Easy quick access to historical data with no middle man required in regards to blockchain.

Correct. In blockchain we don’t rust, we verify.

- By creating a digital system that removes the need for human based trust
- Because a human can alter any entry at will thereby corrupting the database.
- If we no longer need to rely on the insincerity of other humans a system can be infinitely more efficient & secure for the benefit of all.

- Every transaction in blockchain is visible or public to the members, and you can’t modify the existing records, but only add new transaction, and blockchain data is stored in decentralized.
- A normal database is stored in a centralized way and people is able to modify the record in the database.
- It provides transaction trust in a trustless digital world.

How does blockchain enable digital provenance?
A: Blockchain enables provenance through de-centralization and majority node verification. By requiring 51% agreement from nodes on the chain to confirm the ledger, provenance is preserved and protected on the blockchain.
Why doesn’t a normal database bring the same provenance?
A: A conventional database requires “trust” in the entities that produce the data. The conventional database is unable to provide provenance due to the potential of people, organizations, and government entities to alter, delete, and/or falsify data.
Why is digital provenance such a great benefit to many businesses?
A: Provenance provides a benefit due to the “trust-less” nature of the data within the blockchain. This allows business to verify and use the data within their supply and distribution chains with confidence of truth and accuracy.

Welcome to the academy Jovana. Great answers, keep it up.
Correct. It can either be removed or edited. In a normal database there is no immutability.
In bitcoin, transactions are hashed. Hash and encryption are 2 different things. However don’t worry too much about it now. You will learn all about mining and hashing later on in the course. Either way great answers. Keep up the good work.
The key point is that a normal database is usually centralized, meaning it is in full control of 1 or a few people. He/They could use their powers in order to change or remove the history of their database. This system requires human trust. In blockchain we don’t trust, we verify.
- Businesses with true good quality have now an asset / prove against other businesses that just pretend / fake. Everybody knows the picture of a cow standing on a meadow on milk package and everybody know that milk comes from factory. Almost all marketing nowadays is just fake pictures for consumers to feel good. Businesses that really deliver good quality with real claims (of cows on meadows) can now easily prove the quality. Therefore, in future it might be positive again for companies to deliver quality, not to produce in poor countries and fake relabel.
I see what you did there. Nice.
