1. Blockchain allows digital provenence by keeping an open ledger. You can only add data to the blockchain not remove or change it.

2. Normal database is centralized and closed to the public. You have to trust that data isn’t being changed or modified.

3. Beacause you can verify and track the transaction/product.

[lsd777]

a) Blockchain enables the network of many computers around the world that authenticate the transparency of the transaction and confirms it accordingly.
b) data can not be removed from the ledger only added.
c) blockchain is decentralized network which cannot be regulated by single person or institution, so in fact this merit gives a lowest chance of fraud or forgery.

2. Because information can be rectified or deleted from normal database in owner’s favor. Consequently only a decentralise system can guarantee a transparency and prove of provenance

3. digital provenance “kills” TRUST and uplifts VERIFICATION as digital stone for future and existing business builders.

1. How does blockchain enable digital provenance?
2. Why doesn’t a normal database bring the same provenance?
3. Why is digital provenance such a great benefit to many businesses?

1.Digital provenance is enabled by mathematical and scientific proof and every transaction being added in the blockchain
2.A normal database does not track transactions and is based in trust
3.Through digital provenance you can track everything, nothing can be erased and it happens in real time

1. Blockchain enables digital provenance by providing a history, story, or ‘ledger’ to verify where a product or currency comes from. Therefore you have a complete understanding of a products key information.

2. A normal database isnt verified by a decentralized network, and therefore is susceptible to corruption. Also there is a risk for lack of transparency.

3. Digital Provenance can allow consumers to see where their products are coming from, and thus instill a sense of confidence in the business. I believe this increases any and all business: Customer Confidence…just one small example

1. Digital blockchain makes it easy to transact and in trustless environment.
2. Normal database is not efficient and needs transparencies to do transactions.
3. Digital provenance eliminates trust because is in real time in a highly verified transactions.

[AustinBurks]

1. How does blockchain enable digital provenance?
   A. It is a trustless public network that provides immutable information, allowing anyone to track and verify each transaction.
2. Why doesn’t a normal database bring the same provenance?
   A. They can be manipulated. You have to trust that the information is accurate.
3. Why is digital provenance such a great benefit to many businesses?
   A.It allows businesses to verify information

[Conner]

The stone or ledger does not allow you to take anything off or away from the original post. This enables a constant audit trail.

A norma data base allows reversals of transactions or deletions. Block chain does not.

Trusting supply chains makes everyone in the chain liable and vulnerable to the others who must trust that they are telling the whole truth about their piece of the chain. In food, that could be a contaminant.

1:How does blockchain enable digital provenance?
Blockchain enables digital provenance through a trustless public ledger. It is like a digital stone where information can only be added to the blockchain but never removed. All transactions are totally transparent for everyone to see.

2:Why doesn’t a normal database bring the same provenance?
Traditional databases are run by centralised institutions which gives all the trust to a human being, thus allowing temptation for corruption and possible fraud of data. Consumers hand over personal responsibility of their private information- blockchain offers more transparency.

Why is digital provenance such a great benefit to many businesses?
Businesses can benefit from using provenance from the track and trace system all transactions can be audited in real-time. This applies not only to the financial sector but to the food and clothing industries. Consumers can now see for example exactly what ingredients are in their food purchases. Clothing can be accurately traced to its source allowing the consumer to see if the product was made effically.

[CryptoPac]

Blockchain is a public ledger and recorded information added are set on stone and cannot be erased. wich provide trusted or the right word verified provenance.
2.
Becouse a normal database cannot provide provenance, information can be changed and/or manipulated, were in blockchain the information put in cannot be changed, removed and transparent and can be watched in real-time!
3.
I think its revolutionary, and it will change everything we structure our life upon by time. From food, clothes, industries, politics. Poor countrys or countrys behind in tech or resources will have great benefits from blockchain cuz i think decentralization is the key for human success in life!

[Alex.A]

1. How does blockchain enable digital provenance?
   By having the transaction layer and account layer coupled together. The transactions can be examined by anyone because they are immutable and hosted by all nodes in the network. So there is no way to alter the transactions that took place after the fact, therefore the blockchain history can be audited with confidence that it’s in correct state.

2. Why doesn’t a normal database bring the same provenance?
   Because records in the database can be manipulated or corrupted after being created. (mutable)

3. Why is digital provenance such a great benefit to many businesses?
   Because it can provide visibility on where ingredients originated or on the fact that business was done ethically. It ensures truth by having it mathematically verifiable, as opposed to having to trust third parties.

[Gerel]

1. How does blockchain enable digital provenance?
   Through its public ledgers.
2. Why doesn’t a normal database bring the same provenance?
   It can be modified.
3. Why is digital provenance such a great benefit to many businesses?
   It provides transparency and enables businesses and consumers to verify the services and products they’re receiving.

1. How does blockchain enable digital provenance? blockchain can be used to store data that can-not be altered and when you are using blockchain as data storage it can be used in order to trace the origin or learn much more about the product im about to use/buy/eat etc…

2. Why doesn’t a normal database bring the same provenance? a normal database can be manipulated and changed at any given moment, which leads to distrust, you cant verify that the data you are reading is the actual data of the product or it was manipulated in order to meet some requirements or any other possible reason.

3. Why is digital provenance such a great benefit to many businesses? its great to many businesses because it can be used to review the quality of the product and the claims the business claim on the packaging/website/any other possible option, and when something like that happens, businesses will automatically upgrade their products quality, because the customer sees everything.

1-By definition provenance is a history of ownership, blockchain provides this by being a digital open source that any one can look at.
2-Normally on most standard databases information can be removed. Meaning if any dishonesty does take place it may not be caught.
3-Knowing the facts of the products your using/purchasing without the ability of a manufacture changing them over time ensures your final product remains the same.

[veracious]

1. How does blockchain enable digital provenance?
   Blockchain is a database/public ledger that keeps track of all financial transactions and is only for adding not deleting transactions. All is seen on the network as copies are the same.

2. Why doesn’t a normal database bring the same provenance?
   A normal database one is able to make changes by deleting, amending or adding

3. Why is digital provenance such a great benefit to many businesses?
   External auditors are not needed to verify transactions as the public ledger makes auditing easy

[btcjoa]

1. Verifikation of all transactions
2. All transactions are not store
3. Trustlessness

[Kennethbarnesjr]

1. How does blockchain enable digital provenance?

A: Blockchain is a public ledger meaning everyone can see every transaction, and since it is ran by a decentralized network of computers, all information is stored locally. This allows the ability to always add information and never delete information. Which gives people the ability to go back and trace/verify everything.

2. Why doesn’t a normal database bring the same provenance?

A: It doesn’t because a normal database is centralized and all of the information and data is not public. Whatever information is public can be altered or deleted making it an unreliable ledger, and very hard to trace or verify any information/data.

3. Why is digital provenance such a great benefit too many businesses?

A: It allows businesses to have complete transparency with suppliers and manufactures; which creates better relationships with consumers as well.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?
   Blockchain is an immutable data ledger that enables businesses to easily collate their data, along with open data, and also verify key information. Ex: Is this food gluten-free? The blockchain holds the most important information and allows anyone to check its validity.
2. Why doesn’t a normal database bring the same provenance?
   A normal database does not have provenance because the entries are not immutable and could be changed by the owner of the database. It is also not as reliable because the database access may be interrupted if it is a centralized database or distributed database.
3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance is a great benefit to many businesses because they do not have to rely on third parties to audit or access records or transactions - all the data is available in the blockchain.

[kristene]

1. How does blockchain enable digital provenance?
   The blockchain is a trusted database, or digital stone, that stores and verifies transactions. Blockchain is trusted because it is a decentralized system where multiple computer nodes verify each transaction so no mistakes can be made. transactions can only be added. They can never be removed or changed. The transactions are also public for anyone to see.

2. Why doesn’t a normal database bring the same provenance?
   A normal database is centralized. It stores information that can be altered or removed. Transactions are not verified and mistakes can be made.

3.Why is digital provenance such a great benefit to many businesses? It makes auditing more efficient and takes less time. Blockchain technology stores and verifies product information more accurately

[KLove1982]

Glad to be getting back into the course!

1. By being to track things in a transparent concrete way.
   2)In a normal database you have to trust someone elses source information.
2. Because it is trustless and verifiable.

[Monjurul_Alam]

Answer 1

In the blockchain, every transaction is recorded permanently and can not be removed which allows anyone to track back and enables digital provenance.

Answer 2:

In a normal database, recorded information can be changed and removed. So, questions can be raised regarding its validity.

Answer 3:
In blockchain technology, everything can be tracked and audited So it proves the transperency of a business and gains more trust from their customer.
