Homework on Provenance - Questions

Blockchain and Bitcoin 101
#5824
  1. Allows us to see transactions in real time.
  2. Transaction are not verified until audit is done by 3rd party
    3.It eliminates the need for an audit because all transactions are verified on the blockchain.

Blockchain enables digital provenance by providing transparency in transactions and allowing for an audit trail of the transaction. This was evident when ransomware was tracked and wallets were seized from hackers.

  1. How does blockchain enable digital provenance?
    By creating a tracked audit trail of all transactions, provenance is established by allowing transparency.
  2. Why doesn’t a normal database bring the same provenance?
    As Ivan would say, the blockchain is a Digital Stone! The transactions are tracked, and cannot be erased. A regular database is editable and managed centrally and can be hacked.
  3. Why is digital provenance such a great benefit to many businesses?
    If you have worked in the business world lately, you will notice that all softwares haves adapted audit trails within their workflows and track all transactions. In Centralized Systems, this allows management to track the actions of all users and follow the path to enlightenment (who did what).

  1. by tracking and verifying every and each step of the supply chain.

  2. because being a centralized database, information coming from different parts of the supply chain in different manners, one must trust what those origins send us as information. We simply trust and cannot verify the information. And if one is wrong or simply not according to what we need as information for that specific supply chain or production chain, then all is just false. It does not necessarily that the origin of the information is malicious, but it can be wrong.

  3. by having more trustable information to and in time information in order to take decisions in the business.

Trustlessness.I understand the idea that it is not controlled by a central authority but how can the supplier be proven to be trusted and who will verify this ?

#5829

I am not sure if I understand your question but if you mean the quality of the supplier products, such things can’t be verified using codes, what you can do tho if that supplier product is affecting your business, since blockchain provide transparency and provenance, you can know which supplier’s product is affecting bad to ur business.

1.) Blockchain enables digital provenance by providing a network of computers that have all the info on there
2.) Normal databases will need audits to verify transactions
3.) Digital provenance can benefit businesses by allowing them to utilize a trustless network, where no middle man is needed

  1. Blockchain enables digital provenance by allowing data to be stored on the database network. The data’s origin can always be tracked since every transaction involving the data is added to the database/blockchain and cannot be removed. Therefore allowing real time audits of transactions to verify validity and provenance.

  2. A normal database doesn’t provide the same provenance because the data is not public to the user and therefore you must trust the centralized entity running the database to be able to provide the return promised. Accounting and transaction are not transparent with a normal database while they are both baked into transactions on the blockchain.

  3. Digital provenance would allow business to track every ingredient/part of their products from creation to addition into their product. Allowing for full transparency in the supply chain and increases efficiency. Digital provenance removes trust from the equation and allows verification.

Thanks for the reply but your answer is not very clear.What do you mean by product affecting your business,in which way as example?

#5833

Ivan you used the comparison with blockchain and Viking stones saying that you can add data but not remove.It would be easy to e.g damage a stone and thereby removing data?Also is more than 51% of miners collude they can also create massive problems for bitcoin.So it’s probably more accurate to say that it’s good but not impossible to attack/alter.Or am I missing something?Sorry I just started and am new to this .

#5834

I don’t completely understand why the blockchain would make it 100% Trustless? Somewhere in the chain humans are still responsible for the info going onto it,which could be corrupted?

A central authority could still manipulate by laws and regulations how businesses are run ,what is required etc.

How do consumers verify these products if the humans behind it all are corrupted?

  1. How does blockchain enable digital provenance?
    It allows the tracking of a transaction by its address and timestamps and the change of ownerships from the transaction’s origin in addition to the combined transactions and changes to the blockchain.

  2. Why doesn’t a normal database bring the same provenance?
    Data in a normal database can be altered or removed from its origin and can only be accepted at face value and not ultimate truth. All aspects of the data can be potentially altered through intentional manipulation or by accident. Data in a normal database is often centralized without consensus. Determining the origin and a clear path can be difficult and hard to take as the truth.

  3. Why is digital provenance such a great benefit to many businesses?
    It takes away the trust from the process/products/services. It allows the business to have an objective digital checks and balances in the form of timestamps, transaction hashes, and addresses.

  1. Block chain enable tracking of any transiction in the ledger from its origine. Blockchain cointain an original ledger which can not be change by any hacker.
  2. A normal data base cointain real time data it can be download by any one can be verify by any one…
  3. Because digital provinance can verify easly by aanyone. So businesses are sure everything are true in database.

Think like this then, there is no single blockchain(Viking Stone), each node stores its own copy. So you have to damage thousand of stones.

https://www.youtube.com/watch?v=UxyGt58EPa4 this will answer your question plz watch.

#5839

That is the beauty of the peer-to-peer network, blockchain technology can only work correctly with a complete consensus among all users, one can mess with the software but that user doesn’t have the authority for the mess to get accepted in the network.

#5841

But it would have been impossiblle for the Vikings to make thousands of stones exactly the same ?

#5842

Thanks for the video,I will check it out

1.Transactions can be tracked and audited in real time.
2.Normal databases can be duplicated.
3. Trust is being removed. Trustless is want you want, verified by math.

  1. How does blockchain enable digital provenance?

Provenance is the chronology of ownership, and the blockchain allows anyone to go and view how ownership changed over time.

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

Because it’s a centralized database, the provenance cannot be verified. It’s dependent on trust, while the provenance of a blockchain is based on numerous other parties in agreement.

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

Because it allows for a greater level of trust, for all parties involved.
