Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
    By storing the verifications via a public ledger. You are not able to copy so transactions can not be manipulated as the verification shows developments.

  2. Why doesn’t a normal database bring the same provenance?
    Because it is a centralized point it is more based on trust. Blockchain does not have a remove option and is all based on VERIFY.

  3. Why is digital provenance such a great benefit to many businesses?
    Faster / Transparant / More engagement / No Trust - VERIFY

  1. Merging accounting and transactions on to a Viking stone for tracking, tracing, and auditing in one place; and if desired, in real time!

  2. Because there is no transparency.

  3. Because it lets businesses keep track of their products going through the supply chain, cutting losses from theft and fraud as their products through distribution chains while simultaneously building bringing transparency to customers. It is a win-win for all.

  1. How does blockchain enable digital provenance?
    Blockchain can do live auditing to check the provenance of every transaction. The blockchain will store every transaction in a database that cannot be changed, only added on top of.

  2. Why doesn’t a normal database bring the same provenance?
    Because it is based on trust. Some surveys state that up to 30% of producers don’t know what is in there products. On the blockchain you cannot manipulate the data and you can see everything on there.

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

  • It can merge the accounting and the transactions in one database.
  • Businesses do not have to trust suppliers to tell them what quality the products they sell are or even what they are selling. It tells the businesses via digital provenance tracing where it comes from and what the quality could be. You only need to verify the data on the blockchain.

1*Because its decentralised and no central authority can control or manipulate the data stored on the blockchain.

2*Because in a normal database data can be removed or changed and can be lost.

3*More transparent and do not have to trust one central authority.

  1. Blockchain enables digital provenance because it allows for the users to verify the products they are receiving is what was agreed upon, instead of having to trust the suppliers.

  2. Normal database does not bring the same provenance because supplies can still lie about things such as where their products are made and what ingredients are included in their products.

  3. Digital provenance is a great benefit to many businesses because it allows for the flow of honest business to occur seamlessly. When we can verify product quality and transactions and therefore build a trustless world of incredible commerce.

  1. by using chained of single digital signature in a network with Stone like features of open distributed ledger mechanism that can be traced down to the beginning of data entry, publicly.
  2. because a normal database did not use real time entry, so it produce a lot of copied data
  3. because every business need a precise accountable data as soon as possible to reach the maximum potential of every decision making they make.

  1. by an opened platform which is peer to peer and has trusted traceability.
  2. because it’s centeralized and has a middle man who is in charge of the system.
  3. because it’s transparent, traceable, immutable, organised and coordinated in a trustless manner.

  1. How does blockchain enable digital provenance?
    Every node in the blockchain has a copy of the so called “database”. every transaction done is verified by each node and written in this database which is again transparant for each node. no data can be erased from this chain only data can be added. because of this you cannot cheat the system.

  2. Why doesn’t a normal database bring the same provenance?
    Because this database is centralized. a person who has access to the database can edit and remove vital information. I think of corruption: For example: a high placed authority person could be offered a high amount of money to delete or edit vital information.

  3. Why is digital provenance such a great benefit to many businesses?
    transparent, trustless, decentralized.

excuse my english :wink:

Blockchain enables digital provenance as a proof of auditing. It can track and trace financial transactions and audits at the same time.
2. Normal database cannot bring the same provenance, mainly because it cannot be tampered with and also there is no fear of it crashing in the same way normal database can.
3. Digital provenance is good for business in that it provides trustlessness, for example it can prove the ingredients in food.

1 There are copy’s off the ledger through the whole network, the participant’s can check if the transactions are possible.

2 In the blockchain you only can add not remove… in a normal database you can remove information…

3 you can verify whithout being on the spot!

  1. Blockchain enables digital provenance through possibility to track every transaction, and since you can’t change information in previous blocks, you can verify any infomation without trust issues.
  2. Information in normal database can be changed at any time, therefore you can’t fully trust a normal database.
  3. Because it eliminates trust problems and allows you to verify any information on the blockchain.

  1. Information is registered directly from the supplier and placed on a public ledger that is then validated. It can not be manipulated to suit the preference of the middle-men. This enables reliable data that retains its integrity indefinitely.
  2. A normal database is traditionally governed and can therefore be manipulated to suit the preferable outcome of said governance.
  3. Businesses will no longer be required to second guess the integrity of the information they are provided and can trust with confidence.

  1. How does blockchain enable digital provenance?
    The mechanism itself makes it traceable; records are immutable and held on a public ledger and therefore “set in stone”.

  2. Why doesn’t a normal database bring the same provenance?
    Because it is vulnerable and insecure (no decentralization and no traceability implemented).

  3. Why is digital provenance such a great benefit to many businesses?
    Because you don’t have to trust. You can verify by “real-time auditing”.

How does blockchain enable digital provenance?

By creating an immutable transaction block for every transaction.

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

Whit a database, you can alter/delete a record (so the provance can also alter, not the case for the blockchain ledger)

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

It create more transparency and remove some requirement for audit from a third party firms.

  1. Everything written on the ledger is public. There is no way to write false information onto the blockchain.

  2. A normal database is usually held by one or more trusted parties. If these parties betray trust then the ledger can be falsified.

  3. Digital provenance does away with the need for trust. I can do business with a complete stranger and have no need to trust them.

1 The blockchain gives digital provenance because it can only be added to & it is public
2 A normal database can be changed
3 It enables real time auditing & can track goods + it removes the need for trust (trustlesness) It VERIFIES.

#991

ad 1) Blockchain - public ledger - no one can’t remove anything, data cannot be deleted, they are traceable.
ad 2) Normal database can be remove, delete or change by users.
ad 3) Because it brings real time tracing, and also speed in businesses. Everything is public (trust).

#992

  1. By disabling the ability to remove data and by making everything public

  2. It is not free from manipulation

  3. Because they can now remove trust from the equation and instead rely on evidence

  1. Blockchain is decentralized and can’t be changed or manipulated, which means that digital provenance can be verified and no need to trust.
  2. Normal database are controlled by central autorities, and there is a risk that informations or transactions can be modified, manipulated,deleted or even hacked.
  3. Digital provenance allows to verify transactions, tracking products. It is an open transparancy network.
