Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
  • Blockchain is an open ledger, where anything can be verifiable from the source.
  1. Why doesn’t a normal database bring the same provenance?
  • A normal database can be erased, manipulated, or edited.
  1. Why is digital provenance such a great benefit to many businesses?
  • To validate the source, to foster trustless environment.

  1. Being inmutable and truss less.
  2. Because the information is coming and storage in different places.
  3. It does not need third parties to verify the information.

  1. A blockchain enables digital provenance by recording every entrance, even in chronological order.
  2. For me, the answer to the second question is not that obvious. I am not quite sure what a “normal database” means, and it is unfair to compare a blockchain to a “normal database”. I wander if it is so complicated to build a database that can provide you the provenance? That database practically won’t be as secure and reliable as a blockchain, because of the decentralization of the block chain, because of the way that the ledger is created etc. But, the questions is not about the advantages of a blockchain over a “normal data base”… it is about the provenance.
  3. Because they can track whatever they want. (Again, in my opinion the question does not refer to the transparency, to the decentralization etc.).

  1. How does blockchain enable digital provenance?

Blockchain has the track of all actions on the block. It is not possible to change the history written in the blocks. There is no centralised authority that would have the power that other users don’t have.

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

Because normal database is mutable, maybe some people have administrator rights to change something in the database or update it.

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

We can use the database as a company without verifying it with use of other processes that would take additional human resources and money. Also we could make accountant processes easier as we know all transactions and we have all the connections to separate transactions made.

  1. It enables it by creating a digital ledger that is accessible to everyone. Nobody can remove the transactions that have happened, therefor making them irrefutable.

  2. In a normal server based database, you can go back and change the transactions that have happened. There’s always a centralized entity that controls the database and can manipulate the data if they want to.

  3. It creates full transparency, where the customer can actually go and look for themselves and verify the information. That creates a “trust” that can’t be achieved with other methods.

  1. Puts together accounting and transactions in to one layer.
  2. They are centralized, accounting and transactions are separate from each other and transaction are not always transparent. It makes verifying very difficult
    3.You will be able to verify and bring more efficiency to your business.

  1. Blockchain enables digital provenance by running a trustless public network.
  2. Normal database uses trust. Additionally without being viewed publicly there isn’t a way to know for sure.
  3. It represents truth, something every business could benefit from.

  1. Because it is a digitalo stone in which you can only add data, you can not erase it. Everybody can have a copy of it.
  2. Because, as i said above, in blockchain you can only add, but in a normal data base you can also erase, so it can be modified by anyone, anytime.
  3. It is a great benefit to many businesses because they have all transactions in just one place, and they can trace all of financial transactions much easier. plus of that, they donțt have to trust, they have to verify, which is the best thing.

Quick question. I get that the blockchain cannot be manipulated once it is written, but what is stopping the writer from manipulating the blockchain data. For example, in the food supply chain, what is stopping the farmer from not including the additives that they utilise in their produce? How could we “verify” that?

#6334

This can not be verified using code. In blockchain we can only store the origin of the products.

  1. How does blockchain enable digital provenance?
    Because the data on blockchain are immutable - you can change or delete once added data.
    You can track historical data with certainly of their trueness.
    You can not put incorrect data because all is check by every nodes of blockchain.
  2. Why doesn’t a normal database bring the same provenance?
    Because normal database are centralize and you can change or delete added data.
  3. Why is digital provenance such a great benefit to many businesses?
    because when provenance is digital the node which can be over the world verify the data so it makes the system trustless and also it is transparent thanks to digitality of it so we can verify the data looking at what data others added.
    the new data are shown in real time.

well put and concise
thanks!

  1. How does blockchain enable digital provenance?
    It does this by having an open and transparent system of keeping the transactions layer with the accounting layer.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database doesn’t bring the same provenance for the fact that it’s run by ledgers controlled by humans instead of code. Code is a much more trustlessness system than human corruption.

  3. Why is digital provenance such a great benefit to many businesses?
    This helps with transparency for when you’re dealing with suppliers and vendors to be able to backcheck all your imports.

  1. Blockchain is completely traceable because records are public and cannot be erased. Anyone can do anything to the blockchain because it is a public ledger.

  2. A normal database cannot provide the same provenance because in a normal database there must be a centralized owner with control over the entire system, as with blockchain the database is public and irreversible.

  3. Provenance allows verification and validation rather than relying on trust.

  1. By storing data on an immutable distributed ledger that every network member has a full copy of. Data goes in, is verified by the majority of nodes and is then permanent and traceable.
  2. Normal databases aren’t immutable and are controlled by a central authority who can make whatever changes.
  3. Digital provenance is useful because it makes auditing instant and no trust is needed.

  1. The blockchain stores data which is auditable and accessible, making it trustless. In addition, added data can’t be altered, as a local copy of the data is stored on plenty of nodes, so even if a few were altered, nothing would happen.

  2. Lots of trust is involved, and there is no real way of verifying the information

  3. Because it can remove the trust factor involved, making these businesses trustless.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
    It enables it because info can only be written, not ever modified or deleted so you can trace where things have been and in what exact state they were in at that time.

  2. Why doesn’t a normal database bring the same provenance?
    It is centralized. Banks and paypal / stripe / etc validate your transactions and can modify, freeze, withdraw your funds.

  3. Why is digital provenance such a great benefit to many businesses?
    Besides coins, I imagine selling different things as NFTs, using the blockchain to at least track the supply chain. Don’t know how we could track the physical state products yet with blockchain but I’m sure we’re about to find out! Removes trust from the equation by making every thing transparent.

Just two things …
Provenance - You can audit or verify all transaction from the time of creation and as it is distributed ledger i.e full copy of transaction stored in different computers around the world no fraud can occur.
Trustless - You dont need to trust third party for verifying transaction. Anyone anywhere can verify transaction.
Blockchain is amazing

  1. It provides a decentralized, trustless, immutable ledger that cannot be manipulated.

  2. Normal database relies on a third-party who can easily tamper with results if they wish.

  3. So many applications from supply chain tracking, to verifying if the shirt you bought is truly from that brand, where your food was grown, etc.

  1. It gives public transparency of every transaction because they are all on the blockchain and can’t be removed. So everyone can verify the origin of each product.

  2. From a normal database transactions can be removed, erased or be lost. Beside that it’s much more difficult to trace back all the transactions and there is always a middle man that can control or even manipulatie it.

  3. Real-time auditing is possible from everywhere because everything is digital. Beside that you don’t need to have trust issues because everything is verifiable in seconds and that brings more efficiencyn transparancy and assurance.
