Homework on Provenance - Questions

[MortenDK]

1. How does blockchain enable digital provenance_

-Blockchain is a decentralized database, immutable data ledger that is completely transparent and not editable, where no one can block it.

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

-In a normal database it will be stored in one location, where ona blocktain the notes will be spread out and that will make it more secure.
We are seeing a lot of web 2 pages that is getting hack, where the hacker is taking over the system, and for the use to get it back they need to pay a rensome, where on a blockchain that will beimpossible because they need to hack all thousends notes at the same second.

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

More efficiency and reducing cost in away remove the trust and brings transparency.
-Bookkeeping with Invoices can be track in real time.
-Food industry where is the ingredients is coming from, who produce it,
-Factory industry where the material is from and what the material it made of, Slavery.

Provenance is needed in this world! it will not make many business happy for sure, to them that is exploits and cheats, but it’s a big step in the right direction to bring a balance in this world.

1. How does blockchain enable digital provenance? It allows for transparency of all transactions made on the blockchain. For example, you can see real time auditing of any financial or logistical transactions in one place.

2. Why doesn’t a normal database bring the same provenance? In normal database environment, information or transactions can be changed or manipulated. However, the ledger in the blockchain guarantees trusts, and information can be verified.

3. Why is digital provenance such a great benefit to many businesses? All transactions can be traced and verified by doing the math! Therefore creating trust.

1. Blockchain is a public ledger, it gives the community real time transactions, that can be traced back with origin. Blockchain can only be added to and nothing can be removed.

2. Because with a normal database information can be compromised or manipulated, and revolves on trust.

3. Businesses will benefit from digital provenance as its easy accessible information that helps cut out third party’s to access records, audit or check transactions. It gives transparency

[BigTony]

1. Information can only be added to the blockchain never deleted, and it can be publicly viewed. making it a easy for users to confirm past transactions.
   2.Normal database’s can be easily manipulated. Information can be removed or erased if corrupted. “normal” database’s require too much trust from one or both party’s.
2. Trust. Trust. trust. No need to bother with someone’s word of truth. hash # confirm transactions making transparency easy .

[Late]

1. Realtime record
   2.It can be edited
   3.It cant be edited

[ppoluha]

1. By providing an immutable ledger that can be audited in real time
2. Databases can be mutated. And there’s no mechanism for verification
3. Gives customers/users confidence in the information provided by the company.

1. How does blockchain enable digital provenance?
   Immutable public ledger make it possible to track and trace all the transactions done over the blockchain.

2. Why doesn’t a normal database bring the same provenance?
   A normal database is usually deployed in centralized manner and those with the access to the database can perform CRUD on the DB easily. Although by right all the data are protected with certain policy, but still technically be editable.

3. Why is digital provenance such a great benefit to many businesses?
   Many businesses care about the data privacy and security. Although normal database can somehow provide provenance, but not as secure as Digital provenance, and their data is not hosted in centralized db.

1. How does blockchain enable digital provenance?
   Blockchain consists of many nodes, which have the same copy of a database. All database information is synced and verified between different nodes. One can only add information to the blockchain. Once the information is added and verified in the blockchain, it cannot be removed.

2. Why doesn’t a normal database bring the same provenance?
   Normal database can be think of one node, which data changes are not verified. Data can be easily manipulated by changing or deleting data. E.g. one can add assets, information, etc. out of nowhere, because there is no verification to other databases.

3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance provides real time auditing and traceability for the information without trust.

Hello everyone

1- By making it decentralized therefore trust less. in which no central authority or government can control the blockchain and change the data in it.

2- Because there’s a central authority or government that can control it or manipulate it. and there’s a lot of trust involved in a normal database.

3- Transparency… it can bring costumer satisfaction, in which costumers can verify and make sure if the products are high quality or bad quality, and verify if the materials/ingredients that the company say that they use are actually the ones they do, and where are they coming from.

[fredliberman]

1-How does blockchain enable digital provenance?
It tracks all transaction in a public ledger

2-Why doesn’t a normal database bring the same provenance?
In blockchain you cannot change or erase input you can only add information. The information added to the blockchain are verified by the validation mechanism provided by blockchain. This mechanism relies on many and not a central operator or system. Since blockchain is decentralised, the risk of losing data is non existant (the system cannot crash).

3-Why is digital provenance such a great benefit to many businesses?
It creates a trustlessness environment with the possibility of real time auditing and accurate traceability.

1. How does blockchain enable digital provenance?

Blockchain being an open and public ledger where you can only add information and not remove them enables digital provenance. All information about activities is being stored in the same place as chain of information. Financial audit and stock audit can be done in a real time.

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

Normally, we don’t have one database but many databases or layers that ‘dont speak’ to each other. Data is being uploaded, downloaded, analyzed, interpreted, streamlined, uploaded again, format changed etc such as in finance and accounting. The journey of an item or transaction is fragmented which allows for fraud and human error. Databases and audit processes aren’t accessible to third parties … and for banks and for governments we customers are third parties, even though they are using and trading our money.

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

Digital Provenance is a great benefit for many businesses especially those who want to be transparent because it introduces trustlessness both ways: business towards their own suppliers and business towards their customers. It allows business to know exactly where their materials, products are coming from, what was its state at each point, reducing the need for trust. It also allows their customers to verify business’s marketing claims and if they are getting real value for their money.
Further more accounting and audits are very time& people& money consuming. The amount of paperwork and compliance necessary to provide for audit can drain companies resources. Digital provenance can potentially enable audit in real time allowing for instant transparency.

1. How does blockchain enable digital provenance?
   All transactions are public and the past data can not be deleted from BC

2. Why doesn’t a normal database bring the same provenance?
   Because you can remove data from a normal DB. Thus you have not a historical 100% evidence of the past data. BC solves this issue by constructing a hash of all past data inserted into the DB and the past can not be therefore manipulated.

3. Why is digital provenance such a great benefit to many businesses?
   It removes trust from the partnership/transactions, thus allowing each side of the partnership to verify the deal and not just blindly trust the partner.

[JosephGarza]

The Blockchain can be seen as a digital stone element which can process new operations, which once processed or recorded are permanently visible to the network, and once recorded in the network, or the ledger, can no longer be modified.
Databases as we know them require auditing as they are modifiable or alterable and can only provide a certain level of security due to such reasons. This is why databases require auditing. Unlike the Blockchain, since it is possible to change the data that was once entered into a database, provenance can be challenged. The Blockchain provides means to a digital provenance which can be verifiable at any time and by any person at any level within the network, with access to it making it trustless, that is, it can be accessed by anyone with the need to verify, challenge and/or confirm the information that has been recorded in its ledgers.

[Olaf]

1. Blockchain enables digital provenance because it can’t be manipulated because it is decentralized and therefor trust less.

2. A normal database can be manipulated. So it is not trestles. It is not decentralized.

3. Digital provenance is such a great benefit to many businesses because the don’t have to audit themselves to know if the can trust for example their supplier.

1. How does blockchain enable digital provenance?
   Blockchain is like a network. Everyone who has access to the blockchain, also has access to the historical data on the blockchain. Every completed transaction is listed and can’t be deleted. Each computer with access to the blockchain interact to ensure that the data on every computer matches exactly. Since Each transaction is listed on the blockchain, you can then the use that information to trace each component of that transaction. You can trace the parties involved, what was sold or bought, and the amount of each transaction. Since all data is publicly available, and past data is unchangeable the ability to track each transaction becomes very simple. This allows Provenance to exist.

2. Why doesn’t a normal database bring the same provenance?
   A normal database is Centralized. This means there are people with the ability to alter data past or present at any time without the consent of the user. In addition, the individual must trust the website, clothing brand, etc. that they will fulfill the promise requested, and they have no ability to audit the transaction themselves.

3. Why is digital provenance such a great benefit to many businesses?
   It is such a great benefit, because it gives transperacy to the customer. It also provides a business with a way to authenticate each aspect of their products origin.

How does blockchain enable digital provenance?

• Blockchain is a public digital ledger where it accurately keeps track of all the transactions made in its database in real-time.

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

• One main difference between a normal database with blockchain is trust. With blockchain, we do not need trust or we do not have to give trust to another but instead, we verify all the information given. It can also be noted that information given in blockchain is in real-time.

Why is digital provenance such a great benefit to many businesses?

• One thing that is really great about provenance is being able to track all the information given and its real-time auditing that puts the accounting and transactional layer together. And with these, we can now make sure that the information we get is accurate in real-time and at the same time, we may remove the trust we give to the third party who audits our documents or accounting physically, respectively.

These are great benefits to many businesses because it lowers the cost businesses must spend every time they needed these kinds of information and services from an outside source and at the same time, businesses may no longer give trust instead they could verify all the information they need.

[Jaidan905]

1. Blockchain enables digital provernance by having a clear trustless public record or ledger detailing all aspects of a transaction. Being that its on the blockchain it make it almost impossible to change any details relating to a transaction so it creates a paridigm where you can trust this ledger because of the network.

2. Because then its not decentralised and then you have to trust the normal database and not the consensus of a large network

3. It gives businesses the ability to have true information and not to have to trust a single entitity. The ability to verify all the different factors relating to a transaction is of great benefit to multiple industrys.

[abarbir]

1. How does blockchain enable digital provenance?
   Blockchain allows for all information like name, address, etc to be coupled together or bundled within the transaction

2. Why doesn’t a normal database bring the same provenance?
   The verification process that provenance goes through

3. Why is digital provenance such a great benefit to many businesses?
   Real-time activity absent third parties

[vedanta10]

1. How does blockchain enable digital provenance?
   Blockchain is like digital stone. It can not be destroyed so while doing so the ledgers are audited on the go. Provenance will reduce the efforts of auditing these ledgers, in turn will reduce the time and cost.
2. Why doesn’t a normal database bring the same provenance?
   Normal database can be changed. They are owned by private database owners who can make changes in them. We can not trust this data hence normal database does not have provenance.
3. Why is digital provenance such a great benefit to many businesses?
   Data provenance will track the changes made to data, where the data is originated, where it is moving to and who made the changes to it. Blockchain is an immutable ledger and only based upon information from other nodes this data can be changed. Based upon codes the system is self-healing. This is the benefit of digital provenance.

[Bhushan_Pawar]

1. How does blockchain enable digital provenance?

By storing transactions & records on the immutable database. Block chain also enables real time auditing. It helps in tracking in every part of business for ex. supply chain, elections etc. It creates very efficient, trust less & transparent business environment.

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

Normal database are mutable. Information can be changed very easily. Also their security is very much compromised. Wherein blockchain it is impossible to undo or tamper the information once it’s get stored on blockchain.

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

It creates very efficient, trust less & transparent business environment. No intermediaries required or central authorities required. One can build highly secured & trackable business.
