Homework on Provenance - Questions

[nmd55]

1. Blockchain allows us to trace financial transactions. It can put together the accounting layer with the transactional layer. There are other user cases outside of crypto.Blockchain is a public ledger and does not have central authority or government that can control it.

2. There is a lot of trust in normal databases.Block chain is trustless.

3. It will allow businesses to be more efficient and for audits to automatically take place periodically.

1. no one can add fake translation to the system, so it is always the original translation
2. because a database can be easily modified and no one can track of it , it can be track but again there are ways to add fake translation in it .
3. because it will avoid cheating

[CharlieMo]

1. By keeping a permanent ledger of the origin and trail of all transactions.

2. A normal database is centralized and has no way of tracking transactions in real time.

3.Improves efficiency of auditing, as well as providing a transparent and trustless relationship in their supply chain

[vlad_bodrov98]

1. Blockchain allows to track the provenance of a transaction. Every transaction is written on the blockchain and cannot be removed. All entries are stored in a chronological order in the database and cannot be removed once
2. In the normal database, transactions can be removed or erased. If the database crashes , the data stored there could be lost. The central authority could also manipulate data in the normal database.
3. Digital provenance would be a great benefit to many businesses because it would allow customers to trust the business. Customers would be able to see if the products are high quality or bad quality. Customers would also be able to verify ingredients that the company say that they use are actually the ingredients they do use.

What is to stop a supplier from entering incorrect information from the beginning? And follow up is with all the copies of basically false info does that legitimize false or incorrect information?

You can’t enter a wrong transaction on Bitcoin which is its purpose and works great. The problem with supply chains is being solved by other projects, one of them being OriginTrail. I encourage you you check them out and ask them how they solve this problem.

1. Blockchain enable digital provenance through permanent record of data which is unremovable (impossible to delete) and impossible to copy. This record is public so everyone can see it

2. Normal database is not public, can be manipulated, copied, elements can be deleted

3. It brings trust, transparency and reliability

[JAM999]

1. Allows real time auditing . Transactions and accounts can happen at the same time in the same space.
   open knowledge, public ledger.

2)not transparent- not accessible to everyone , data can be altered.
3)instant, traceability, transparent.

1. How does blockchain enable digital provenance?
   IT does enable the digital provenance by assuring the immutability of the data inserted into the blockchain.
   2.Why doesn’t a normal database bring the same provenance?
   Cause in most cases it can be modified, so anyone can change the data and brake the traceability.
   In case you use an only lecture database (does it exists?) you couldnt verify the transactions, cause the only thing you could do is to trust the information that somebody with the ability to modify the database gives you.
   3.Why is digital provenance such a great benefit to many businesses?
2. Why is digital provenance such a great benefit to many businesses?
   It ensures traceability, which can be used with goods, financial, raw materials, etc…

1. Because everyone can see all transactions that ever been made. You can never delete information and transactions, only add.
2. Because a normal database is not decentralized and its not transparent.
3. Because you´re able to track everything and that you can trace it in real time.

[vero]

1. How does blockchain enable digital provenance?
   By keeping track of every transaction, which means that the blockchain is keeping track of every single change made to the original data and when the change was made (without deleting any of the previous changes), so people can be certain of the legitimacy of the changes.

2. Why doesn’t a normal database bring the same provenance?
   Because in normal databases, usually new data replaces old data and records of all changes are not necessarily kept. Normal databases are centralised and can be modified by an authority, who may or may not chose to keep a record of the change to the database.

3. Why is digital provenance such a great benefit to many businesses?
   Because it enhances security. Information or data loss is very unlikely and the legitimacy of everything can be verified (all the components of a product, or all the ingredients in food, etc.)

[hrvoje]

1. Through putting together the transaction layer and the accounting layer, it is possible to track everything in real time.

2. It takes much longer and can be corrupted by people.

3. Digital provenance doesn´t need any trust to be involved and it´s a lot faster.

[cypher]

1. How does blockchain enable digital provenance?
   every transaction is written in the blockchain

2. Why doesn’t a normal database bring the same provenance?
   in blockchain, you can only add information

3. Why is digital provenance such a great benefit to many businesses?
   to remove trust with and being a public ledge

[PaiviL]

1. Blockchain tracks every transaction and cannot be changed after the fact and it is also an open ledger so anyone can verify the transactions.
2. In a database one can edit the transactions after they’ve been added also you have to trust people to add correct data.
3. Because trustlessness, you don’t need to trust when you can verify the transaction.

[melatamps]

1. How does blockchain enable digital provenance?
   By being able to keep track of everything in real time and non removable

2. Why doesn’t a normal database bring the same provenance?
   A normal database is centralized so whoever authorized can possibly change the data

3. Why is digital provenance such a great benefit to many businesses?
   By saving lots of time, costs (to physically doing a face to face audit etc), and enhanced security by removing trust to any other parties involved

[PartalosCrypto]

1. Blockchain enables digital provenance as it helps provide a digital real time record of data or information which is immutable. Once in its in,

2. A normal database does not bring the same provenance as it is expensive, slow, lengthily implementation and open to corruption.

3. Digital provenance is a great benefit to many businesses as it is faster to implement, it eliminates trust, provides verification and it provide private and public access.

[smfl]

1. How does blockchain enable digital provenance? Blockchain stores data that can’t be removed or modified. Since blockchain is a public ledger it can be accessible anytime by anyone. All stored data is transparent, traceable and accurate. No trust involved.
2. Why doesn’t a normal database bring the same provenance? A normal database isn’t transparent. A normal database can be easier attacked or corrupted, data can be removed, modified or added without verification.
3. Why is digital provenance such a great benefit to many businesses? Because all data recorded on a blockchain that provides transparence, accuracy and security. It is beneficial for both businesses and their clients because it enables trustlessness. Both business and clients can reach data anytime anywhere. Blockchain removes need in middleman that makes businesses work more efficient.

[Phillipe089]

1. How does blockchain enable digital provenance?
   Answer : every transaction is tracked in real time.

2. Why doesn’t a normal database bring the same provenance?
   Answer : account and transaction layer are seperated from each other.

3. Why is digital provenance such a great benefit to many businesses?
   Answer : capeable of retracing things and trustless

[A-Bay]

How does blockchain enable digital provenance?
-By tracking and recording every single transaction in the history of the blockchain

Why doesn’t a normal database bring the same provenance?
-Because a normal database ca be manipulated by the author of the database and it requires manual entry of transactions

Why is digital provenance such a great benefit to many businesses?
Because it removes the need for trust. Everything becomes verifiable and transparent. Tranactions records cannot be manipulated or corrupted.

[Kevin_G]

1: Blockchain is like a digital stone, therefore you can track processes backwards. In this way you can always find the origin of the subject.

2: A normal database is based on trust. A decentralized blockchain is not.

3: Digital provenance through blockchain provides businesses with an easy, efficient and reliable way of keeping track of provenance. it is transparrent and backward traceable.

[Piers_Sciolti]

1. Blockchain enables digital provenance by being verified by multiple sources across the world on the blockchain. Everything is traceable.
2. A normal database doesn’t bring the same provenance because it allows transactions and accounting to all be in the same place where a normal database they would be seperate.
3. Digital provenance is such a great benefit because it removes the trust element that their ingredients or materials in their products really come from where they say it does. This means that customers can buy in confidence. Don’t trust, verify
