Homework on Provenance - Questions

  1. Because the blockchain technology adds all doings and it not possible to delete anything from the blockchain. So for example, I manufacture food, in my product I add salt, the blockchain ‘detects’ that and will add it to its block and therefore it will be always there in the blockchain to verify/look back on.

  2. Because it can never be as quick as the blockchain and never be as accurate, trust will always be involved if we do it in a normal database because you can delete things from the database.

  3. Its easy and when the software is doing its job, its doing its job and therefore really accurate because it uses math instead of human brains.

  1. By being a trustless system with no central authority that is a permanet record that can only be added to.
  2. A normal database can be retrospectively edited at any time so the accuracy and legitimacy of its content can be brought into question.
  3. Digital provenance gives the opportunity to automatically verify data almost instantly, removing the need for trusting 3rd parties data and timely manual verification of the data.

1- Blockchain enables digital provenance, by tracking and verifying transactions in real time (RTO) on a public ledger.

2-Normal database is not completely public and transparent, therefore it can not be 100% Trusted.

3-It eliminates any intermediary and provides the initial, verified data provenance, giving 100% Trust.

  1. How does blockchain enable digital provenance?

BC enables digital governance via ledgers and validating all information put in blockchain. All informations can be traces and it cannot be modified.

  1. Why doesn’t a normal database bring the same provenance?
    Normal database can me edited or deleted, tampered or otherwise corrupted. In ordinary databases information is usually also scattered to various databases and this might cause errors and differences between informations. Like in accounting information and transactions do not go hand in hand

  2. Why is digital provenance such a great benefit to many businesses?
    BlockChain removes the “trust” effect from the equation and everything is based open data which cannot be modified. You can track everything and follow information in realtime. Information and history can be seen transparently which removes the need of trust and errors

  1. Blockchain ensures all transactions are immutable, so we can be sure they weren’t changed.

  2. Data stored in a normal database might be changed.

  3. Digital provanance allow many businesses to rely on the data, which are stored in blockchain.

1.How does blockchain enable digital provenance?
Blockchain is a network of computers. Each block store a copy of the information of the transaction. All the data is unremovable. Blockchain is
a public ledger in which every transaction can be traced and tracked.

2.Why doesn’t a normal database bring the same provenance?
A normal database is most time centralized, it is owned by a private or authority. All the data can be easily removed, changed, or deleted by the will of the owner

3.Why is digital provenance such a great benefit to many businesses?
Digital provenance can help enterprises to save time and money.
Since all the information and transaction data be put in the blockchain which can not be changed or removed, the information is more transparent. So they can build more trust between user’s and companies

How does blockchain enable digital provenance?

Blockchain enables digital provenance by being able to track and verify transactions in a block in real time on a public ledger.

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

Because normal databases are often centralized and data can be changed or removed by the owner.

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

It speeds up the whole process and the company can work more efficiently. You can track everything in real-time so its not necessary to rely on trust.

1 Blockchain is a public ledger that anyone can verify ang track all transaction.

2 Because theres a lot of trust and we human can easily change everything, and manipulate datas.

3 Every transaction is recorded and we cant change any transaction. this is a great benefit to many business.

  1. Blockchain offers a digital public ledger to track each single transaction. It is impossible to change or delete past transaction events. In addition the decentralized topology of the blockchain network ensures that a single participant can’t compromise the data.

  2. Standard DB is owned by a single entity / admin that always has the power to change / duplicate / erase data. No validation possible if transactions were faked. Additional risk of shutdown of a central DB.

  3. Traceability is a major issue in most supply chains today. Participants in the system need to trust that the provided data is valid, but there is no proof. Blockchain ensures that each single transaction is correct and confirmed by other network nodes. Everyone can verify the transactions on the public blockchain, no cheating possible.

1. How does blockchain enable digital provenance?
Blockchain enables digital provenance by tracking information trustless. Information in the blockchain can not be removed.
All information will be stored on a network of computers, every computer has the complete blockchain with every information stored. When a new transaction is added to the blockchain it will be verified by all computers in the network, which makes the blockchain immutabale.
2. Why doesn’t a normal database bring the same provenance?
A normal database is not immutable - information can be changed or erased.
They are also often controlled by a central authority.
3. Why is digital provenance such a great benefit to many businesses?
It’s a simple way to track data trustless and immutable with a lot of use cases and transparent for all users.
Also with the possibility of real time auditing and traceability.

    Data on the ledger can not be removed only added. The data is stored on several computers and verified by all in the network. So digital provenance can not be altered.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database can be altered

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance makes it possible to verify transactions and spend less time auditing them. If they efficiantly can verify rather than in many ways rely on trust in their supply chains it would be a great way of making sure their business is conducted fairly.

    By tracking the relevant information from the beginning - it provides an electronic audit trail

  2. Why doesn’t a normal database bring the same provenance?
    Traditional databases won’t have all the transaction information and history together in one place. Also, buy just having one database, there still has to be trust. With distributed technology like blockchain, we don’t have to trust, we can verify.

3.Why is digital provenance such a great benefit to many businesses? It will enhance supply chain processes and remove dependency on trust.

1, How does blockchain enable digital provenance?

  • By verifying and tracking transactions without the question of trust.

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

  • Because the data can be altered and not accessible for the public and the control is in third party hands.

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

  • All data traceable and transparent from the very beginning and also accounting and transaction happens in the same time.

  1. How does blockchain enable digital provenance?

Blockchain allows for tracking of all data being added to the blockchain via a public ledger that cannot be changed.
This means that everything can be tracked in real-time, and removes trust from the equation in a transaction.

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

Normal database can be edited, you can update/delete data from a normal database,
meaning that transactions could be altered or erased.
Normal database does not rely on a network of computers to verify and ensure transactions are real.
Data can be easily manipulated and changed by an individual, admin, government, etc.

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

It allows for total transparency for transactions in real time, allowing for smoother accounting of funds, with total autonomy.
Digital provenance removes any need for a business to trust its suppliers/partners, it brings more transparency to customers.

1- making it decentralized therefore trust less. in which no central authority or government can control the blockcahin change the data in it.

2- there’s a central authority or government that can control it or manipulate it. and there’s a lot of trust involved in a normal database.

3- it can bring costumer satisfaction, in which costumers can verify and make sure if the products are high quality or bad quality, and verify if the materials/ingredients that the company say that they use are actually the ones they do, and where are they coming from

  1. Blockchain enables digital provenance by removing trust and with verifies transactions agreed upon by many computers on the blockchain. Because the block chain is decentralised information can only be added to the blockchain not taken away. This means that the information is added and verified by a series of computers and cannot be edited by anyone.

  2. A normal database can not provide the same provenance as they are not decentralised and means that you are trusting that a third party is not editing/removing information. You are relying on trust instead of verifying through blockchain. If there was a loss of power centralised databases can lose information that isn’t saved, whereas with blockchain the information is being stored live all over the world on chain.

  3. Digital provenance provides a great benefit to businesses because they can track and trace what going on with their products in real time. They can produce real time auditing on there products meaning customers can have full faith that the product is what it is said to be.

  1. Blockchain enables “trustlessness”. All transactions are verifiable and can be audited as required (Public Ledger).
  2. Relies greatly on trust and data lags or can be withheld from information on movement of goods/services to obfuscate.
  3. Efficiency in terms of data availability, accuracy, auditing which translates into better experience/satisfaction as well as confidence in component quality, sourcing, and factory conditions.
