  1. It verifies every transaction, or step in a process. Since it is in the Blockchain, it is only entered once, and can’t be erased. It is 100% computerized
  2. A normal database is based on trust. Humans are involved, which makes mistakes. Provenance is decentralized and doesn’t have to be checked, since it tracks facts & is always right
  3. It is trustless. You don’t have to rely on someone’s word, or worry about them stretching the truth or not knowing

1.because of blockchain it is decentralized and therfore trustless. so no central authority can change the data.

  1. because it is centralized and therefore based on trust wich can be altered.

3.there is no trust needed everything can be verifyd

  1. Blockchain enables digital provenance by creating an immutable and transparent digital ledger which can be tracked and verified by participating nodes on the network at all times.

  2. A normal database which is hosted on a centralized server (on-prem or cloud) is managed by a designated admin(s) and those admins can add, modify and/or remove data on that database without any cosensus from the other admins (if any) as long as they have the appropriate permissions to do so making it much easier for the data to be manipulated and/or corrupted. Also, unless some form of auditing has been enabled to check/monitor event logs on the server, the ability to track changes to the data would be very difficult if not impossible.

  3. Digital provenance is a great benefit to many businesses because it gives them the ability to track and verify the history of any digital transaction from beginning to end without having to question its authenticity.

  1. Blockchain enables digital prevenance because of the public ledger. This public ledger is immutable (similar to stone) and data can only be added, not removed. This allows for complete transparency because transactions can be verified.

  2. A normal database is not distributed across many different computers. A normal database is controlled by a centralized entity that can ultimately manipulate its data however they see fit.

  3. Digital provenance is a great benefit to many businesses because it allows for the business customers to trust the business 100%.

  1. Blockchain enables digital provenance not by trust but by having a digital receipt which is public and everyone can see it.You can see all your transactions at all times.

  2. A normal database is dependant on a third party, which we have to trust, because there is no proof of transactions written. Even if there was a proof it could be falsified. In blockchain that is not the case because all the transactions are written once and cannot be erased.

3.Digital provenance is great because it assures you of the quality of the product and you have written proof of it.

Homework on Provenance - Questions

How does blockchain enable digital provenance?

Blockchain enables digital provenance by using a network of computers to verify transactions

  • kind of like a digital public ledger. Each transaction is recorded which allows people to
    observe chains, or series, of transactions

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

A normal database is centralized and is the only machine/ algorithm verifying a transaction.
This results in data being subject to the will of the 1 computer - if someone tampers with
the data or the machine is corrupted then the data is no longer accurate

Blockchain is a network of computers that are generally in mass agreement of an action -
computers on the blockchain verify transactions together and generally share the same
consensus - therefore tricking or corrupting a few machines would not cause the whole of
the data to be lost

Why is digital provenance such a great benefit to many businesses?
Digital provenance would allow for business to occur more smoothly, efficiently, reliably,
and verify-ably. Also companies could save on the salaries of accountants as they would no longer
be needed in large amounts

  1. Blockchain enables digital provenance by verifying the origin or source of transactions etc.

  2. A normal database does not bring the same provenance as blockchain because you have to trust the party responsible for the source data.

  3. Digital provenance is such a great benefit to many businesses because it can help verify the origins and authenticity of materials with regards to their supply chains and inventory.

  • How does blockchain enable digital provenance?
    Immutable record keeps in real time.

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

  • Why is digital provenance such a great benefit to many businesses?
    No need middle man using, simplification, machine to machine trustless contract.

  1. Blockchain enables this by creating real time verifiable transactions and tracking.
  2. And a normal database cannot do this because it is not decentralized and there is always room for error or control over the actual data.
  3. Digital provenance is a huge benefit to every business to track and store data that will never be altered or changed and can be “audited” and viewed publicly. This will ensure trustlessness and that solves many problems in modern day business transactions b2b and b2c

  1. How does blockchain enable digital provenance?

Blockchain enable digital provence due to its immutability, meaning that transactions cannot be deleted or changed once they are on the blockchain. This way you will always be capable to track the origin of “funds” by tracking all previous transactions. This characteristic is only possible because blockchains are trustless database and are not controlled by a single organization.

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

A normal database can have it’s transactions changed if a central controller wish to do it.

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

Because many business depend on trusting in their business partners to guarantee the origin of funds or goods. Using blockchains to track all steps will remove the need to trust and thus will make everything more transparent.

  1. by being a public ledger that cannot be changed, it allows anyone to audit any transaction.

  2. because those databases are not on the blockchain, they’re transactions lack information.

  3. by removing trust, businesses can check where the supplier is getting its items from .

  1. In blockchain every transaction is public and needs to be verified by nodes before it is accepted in blockchain. Big companies like IMB helps improve provenance for blockchain.

  2. With digital provenance for bitcoin everything exists only in internet. So bitcoin proves that provenance in digital world could exist. Normal databases needs more time and education how to implement this in their buisness. In real world many things need to be check real time.

  3. It would be easier to check if everything is fine. It could economy money and most important time.

1.By keeping permanent records and making transactions verified and trusted.
2.Because they are stored in a central location rather than being distributed among many nudes.
3. It’s way safer, tracks in real time, no third parties and removes trust issues from the equation.

  1. Blockchain is a type data structure, that is in effect acting as a database, but where data can only be added and not removed. This feature is achieved by having the blockchain operate on a decentralised network of computers. Since all possible transactions would be saved in this data structure, it is referred to as a public ledger, because this data is accessible to anyone. Provenance is enabled since any transaction on the blockchain can be tracked and audited in real time.

  2. A normal database is typically operated on by a centralised set of computers. Data can be added or removed as per the wishes of such a centralised structure. Data is not accessible to anyone, only those the centralised structure permits. For these reasons, provenance of the kind achieved by blockchain is not achieved.

  3. Because digital provenance goes hand-in-hand with public ledgers, the barrier between accounting and transactions themselves is greatly reduced, allowing real-time digital auditing. Beyond this, any industry that currently relies on trust between agents, and is opaque concerning product information, would stand to possibly benefit from blockchain technology.

1 by keeping an immutable record of all past transactions ever made and by who in a decentralise network of computers

2 a normal database can easily be altered

3 because it brings high level of trust without the need for a 3rd party
