Homework on Provenance - Questions

How does blockchain enable digital provenance?
Enabling trustless and verifiable networks and systems.

Why doesn’t a normal database bring the same provenance?
It is mutable (changeable), it depends on a central governance which is a single point of failure.

Why is digital provenance such a great benefit to many businesses?
Less resources to be spent on accounting, and anyone can benefit from the transparency it brings.

1.by making it decentralized trust less . in which no central or goverment can control the blockcahin or change the data in it
2.becaus there is an central that can conrol it or manipulate it and there is alot of of trust involved in an database
3.becuese it can make an costumer happy or in witch costumers can control the quality too make sure if it an bad or good product and too be sure where it cum from

  1. How does blockchain enable digital provenance?
    Blockhain is able to provide digital provenance by using distributed ledger technology which means that a lot of computers are verifying everything that is happening, and checking that it is in accordance to the code.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database cannot bring the same provenance because there is a middle layer in between the information that the database is tracking and the database itself, you have to input it instead of it being intertwined.

  3. Why is digital provenance such a great benefit to many businesses?
    It can cut out many middlemen such as accounting firms. In addition, It can bring transparency to customers on the supply chain of products.

  1. Blockchain enables digital provenance by enabling all users to view & audit the blockchain’s data through the public ledger, which anyone can download and verify. This data is decentralized, verified, and maintained by end users who all download copies of the Blockchain and continue to verify it as it updates.

  2. A normal database does not bring the same provenance because the information it stores is on a centralized server and is not viewable, nor does it allow public users to audit the data.

  3. Digital provenance is a benefit to many businesses because they do not need to rely on their customers’ trust, over the course of a financial transaction, because these transactions are fully transparent.

1.-Because the Blockchain is virtually immutable and allows for the tracing of elements since origin. It is also decentralized.
2.-Because they can be altered and are centralized (inefficient).
3.-Because it allows for tighter control in business operations.

  1. Blockchain enables digital provenance by allowing to only add information and not remove. Then, this information is publicly available and verified by the whole network.
  2. A normal database doesn’t bring the same provenance because it will have a possibility to remove, edit or hide data. You have to trust admins of the database, rely on the information they have shared and believe it is not altered.
  3. Digital provenance is a great benefit to businesses who want to prove their customers that their product has certain and only certain contents in it, that they actually use the technology they claim to use, and thus the quality will be as expected. Also, it is an easier way for startups to prove how they used the received investments or donations.

Answers on Provenance - Questions:

  1. Blockchain integration could improve efficiency and transparency in many processes in our daily lives, by potentially eliminating (optimizing) the need of middlemen, therefore lowering the risks of human errors or human related exploitation.

  2. A normal database could be hacked or modified unlike a blockchain that is constantly verified by multiple computers/machines/servers that share the same database/ledger (like information inscribed in stones or a historical DNA).

  3. Digital provenance can, overall, optimize existing businesses operations because it can lower inefficiencies, thus risks and costs, and, depending on the subject that is being improved, it can increase transparency, create a trustless scenario and allow businesses shuffle its resources to create additional value for the businesses. In financial auditing, blockchain could optimize the quality of the audits and again, better transparency and maybe, tackle corruption!

  1. How does blockchain enable digital provenance?

Block chain enables digital provenance by removing the need for a central authority needed to verify transactions. Instead of having 1 central authority, blockchain distributes the ledger to all the nodes in the system mining. With each transaction the proof of history is provided to add a layer of verification.

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

A normal database does not bring the same provenance because normal databases allow for reading, writing, and edits to prior transactions. Blockchain is a database that is 1 decentralized and 2, only allows data to be added to it.

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

Digital provenance is such a great benefit because it removes the level of trust we have had with control of information. It allows for complete chronology of ownership for example in supply chains. There are many real world applications for this need.

Great answers. All on point. Keep up it up. :slight_smile:

Its important to mention that in the blockchain, you can only add information. You cannot remove or edit the past. This enables digital provenance and accounting.

I agree. Originals does sound better. And its true, we keep updating the original chain started by satoshi nakamoto. :smiley:

  1. By carving every tansaction in digital stone. Every transaction made in the past can be found and traced back. Agreements cannot be changed in the future.
  2. In a normal database data can be changed. the provenance is only based on the trust that the data is not altered. That comes with big risk.
  3. It will leave out “the middle man” like a notary, accountants or consultants (like my job :frowning: ) while increasing the outcome of security. in short: cheaper with better results.

  1. Blockchain allows digital provenance thanks to the computer network that track all the transactions that cannot be erased from that network’s memory. Which in turn allows for very clear tracking of all the transactions.

  2. It is because there is no blockchain algorithm there. Blockchain being digital stone to which you can add information but cannot remove differes from normal database where you can actually remove data.

  3. Digital provenance is a great benefit to many businesses because of the fact that it elimnates TRUST issues and i.e. food sellers have exact track record of where the food they sell come from instead of realying only on the data they get from suppliers.

  1. Because it can track all transactions and verify them without the need for a middle man.
  2. Because a normal database can be altered and does not provide much information about the transaction.
    3.Because it can make businesses more transparent and efficient.

  1. Provenance allows real time auditing on the blockchain because it is decentralized.

  2. A normal database is not open so it can be manipulated by whoever controls it.

  3. Digital provenance is a benefit because it is transparent and can build trust in many businesses.

  1. Blockchain technology provides a public ledger, where data cannot be modified or deleted afterwards. Since all participants of the network have a copy and confirmations between participants are needed, no single one entity can manipulate the data, trying to defraud the others. Basically all participants follow all of the transactions/data entries simultaneously and independent of each other, without relying on any other party, while at the same time constantly comparing notes with the network / everybody else.

  2. A normal database has no inherent protection against manipulation, and is especially vulnerable against it by the ones who control it. For ex. think data base owner/company vs users/clients.

  3. Because it gives them the ability to not only track, control and verify their data themselves - for example in a production chain, what goes into their products, including from suppliers - they can also publicly pass on these data streams and therefore boost end-consumer trust, which is extremely important and sensitive.

  1. How does blockchain enable digital provenance?

Transparency, being able to trace the origin of the transactions. A transaction can be registered but not modify.

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

A central database is controlled by one entity and the transactions can be altered. You are reliant on trust.

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

The transparency allows businesses to trace all verified transactions to the source, giving them confidence that the information provided is correct. Simplifying the auditing process.

  1. blockchain fundamentally enable the “tracking” (provenance) having a public ledger, which cannot be modified. in this way you can easily track for example all the financial transactions (real time auditing), or provenience and status of foods / ingredients
  2. a normal database enable you to delete data, is not shared - so there is not a real possibility of verifying (don’t trust - verify!)
  3. at the end of the story, digital provenance enable you “for free” a service which will be otherwise quite expensive, give you guarantee of quality and it is a proof of what has happened. Last but not least, it can reduce your costs (e.g. auditing)

1.) A digital stone of unerasable, but traceable transactions that is publicly verifiable is what blockchain technology provides for.

2.) A normal database can be changed, or have data removed from, a database that can ONLY be written to is a game changer.

3.) I don’t necessarily like the emphasis on “trustless,” but I think a positive focus on verifiable from the consumer end is huge; the quote of “trust, but verify” or even better is “trust and verifiable.” Blockchain is a whole new level of peace of mind for the consumer, or client, and that is very important it seems to me.
