Homework on Provenance - Questions

  1. All transactions on the blockchain are stored and cannot be removed or changed after being confirmed, everyone can look on the blockchain to find all the transactions.
    its all decentralized.

  2. in a normal database things can be removed or changed, not everybody can look in every database.

3.it can save a lot of cost for book keeping and you dont need an accountant and al receipst of everything you purchase.

  1. Through consensus across several nodes on the blockchain.
  2. A normal database can be changed by the administrator and we have to trust that information is unaltered.
  3. In order to provide assurance of a quality product, a business needs to build a reputation of quality. If you can trace the inception of a product to the source, including all the components of the product, trust is verifiable at the launch. The entire supply chain becomes responsible for the end product.

1. How does blockchain enable digital provenance?
Digital provenance is possible due to Blockchain being able to provide complete transparency and traceability. This is possible through Blockchain being a de-centralized public ledger database that cannot be altered or changed. The Blockchain can only have transactions added, not removed.

2. Why doesn’t a normal database bring the same provenance?
Normal databases are centralized, stored in a single location - setup, controlled and managed by a sole entity, either a company or an individual.

Normal databases can be hacked, copied, edited and manipulated, Blockchain public ledger databases are a decentralized network, that is not controlled by a sole entity. Entries on the Blockchain database past and present - cannot be altered.

3. Why is digital provenance such a great benefit to many businesses?
Blockchain puts the accounting layer and the transaction layer together, providing real-time auditing of each transaction. From financial transactions to origins of food in the supply chain.

Blockchain makes digital providence possible, with each transaction and source of supply being fully traceable and verifiable. Business relationships are based on the verification, not trust. Blockchain also provides ease of accounting and accuracy, with real-time auditing through the transaction layer and accounting layer – being together.

  1. Blockchain is the database where all bitcoin transactions are stored and all of these are completely open to the public, so anyone can verify all the transactions.

  2. A normal database is centralised, there’s a central authority that can control it, a transaction can be removed or erased and can easily be manipulated.

  3. Because of transparency, it is not based on trust, it is verifiable. It can bring customers satisfaction and can help with their purchasing choices because it can verify the claims of authenticity, production etc.

  1. How does blockchain enable digital provenance?

Because blockchain technology makes provenance transparant and verifiable by everyone in the network.

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

Because in most cases a normal database is not as transparant as blockchain and can often only be verified by a few stakeholders/administrators. It’s based on trust and not mathematical verification. In other words: with a normal database you never really know for sure if it works honest and accordingly (and that’s not the same provenance).

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

Because you can have more control and transparancy over the transactions you make with others directly (so without the middle man :wink: ). ‘Others’ such as suppliers, customers, stakeholders and also employees.
There is no need for a third party to verivy the transactions anymore (which in most cases saves you a lot of time and money!).

  1. Blochchain allows us to constantly track and verify all transactions and data within its database, which allows for digital provenance.
  2. In a normal database transactions and data are not solidified. They can be removed, lost, or altered, which in turn makes the data less reliable. This means there is more emphasis on trust than actual verification.
  3. Digital provenance allows businesses to accurately track all transactions and data that are directly related to their business. They will no longer need to rely on trust with their collaborators, and will instead be able to verify with indisputable facts. Real time auditing will now be possible, as accounting and transactions become one in the same.

1.- In the blockchain every transaction is verified by all nodes and can’t be deleted and is also publicly open to anyone.

2.- Because in a normal database you can just delete previous data or manipulate it. Once a transaction is written on the blockchain data it can’t be edited or deleted.

3.- Because the intermediate is becoming obsolete. You don’t have to trust a third party, the blockchain verifies transactions or information automatically which gives great benefit to the customer because he can be sure about the information on the blockchain being true and verified

  1. How does blockchain enable digital provenance?
    Blockchain enables digital provenance by keeping an immutable history of data, traceable,
    decentralized, public, and in real-time.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database doesn’t bring the same provenance because it can be changed resulting in both
    fraud and errors.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is a great benefit to businesses because it verifies claims of origin, authenticity,
    and production. Helping to build complete trust with both their consumers & suppliers. Also,
    simplifies any audits.

  1. How does blockchain enable digital provenance?

All transactions on the blockchain are recorded aka set in stone and cannot be changed, so everything on the chain is ultimately traceable, enabling full provenance for anyone to verify.

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

A normal database cannot track and audit in real time, accounting and transactions have to be done separately and by different departments, it requires a lot of trust whereas a blockchain achieves this all in one place

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

It takes away having to trust others to do the job, its verifiable publicly and privately for taxation and any other accounting purposes.

  1. Blockchain provides real time auditing to allow provenance.
  2. This database is not necessarily live and can be changed or subject to change without verification from outside sources.
  3. Digital provenance will remove the need for trust and will allow real time verification of transactions / tracking of ingredients or parts etc depending of the industry and will allow it to happen in such a way that it can’t be changed or edited without verification from the block chain.

1. How does blockchain enable digital provenance?
Blockchain enables digital provenance by verifying every block in the chain in a big public ledger that does not allow anyone to remove any information that it received. This way the ledger is 100% trustworthy because it can verify all information on the blockchain.

2. Why doesn’t a normal database bring the same provenance?
A normal database doesn’t bring the same provenance as the blockchain because it’s not 100% trustworthy because you can remove information out a normal database.

3. Why is digital provenance such a great benefit to many businesses?
Digital provenance is a great benefit to many businesses because it’s 100% trustworthy and it can save a lot of money and time. With digital provenance businesses can work way more efficiently and cost effectively.

Blockchain is a public ledger where you can trace transactions. The trace of transactions is secure because once a transaction is on the blockchain it can’t be erased. Every transaction must be verified by multiple blocks for approval.
2. Why doesn’t a normal database bring the same provenance?
Because a normal database is easy to manipulate. You can add or erase transactions without verification. A normal database is based on trust and blockchain is based on verification.
3. Why is digital provenance such a great benefit to many businesses?
Digital provenance is beneficial for many businesses because it is a trustworthy way of tracing a company’s products and/or services. It’s also a cheaper way of controlling a company’s finances.

Once the transaction is written it is unchangeable, any transaction is viewable and verifiable.

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

Trust is the main factor for this, normal database’s don’t have multiple verifiable entities that you can verify authenticity

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

Being able to verify the accuracy and authenticity of products, or assets is huge on a global scale. Having the ability to not only verify that a product is what it says but be able to have multiple source’s of truth. I.e Verifying that a specific food or medicine is indeed what it is labeled.
