Homework on Provenance - Questions

  1. Provenance in blockchain is done by using a digital signature that will authenticate and record that information onto the blockchain, making it immutable.

  2. A normal database can’t bring the same provenance that blockchain offers because data in a normal database can be tampered with.

  3. Digital provenance is great for businesses because it will help create trust and authenticity of the product between the customers and the manufacturers.

  1. By keeping record of everything that happens on network, making it completly trasnparent. You cannot lie to me if i can google the truth, so if i can see that your account has no BTC in it and you try to convince me that you’re a Nigerian prince who just need a 100$ and then you will ship me 1Bulljon BTC i can just check it. :smiley:
  2. Cuz’ they have a gatekeepers i.e. they are not visible to public, someone can change information that is in that database. And they are physically somewhere and sure they have backups, but they can be destroyed.
  3. I dont need to take your word, i can see for myself.

  1. Through the transparent nature of a distributed ledger.
  2. It can be owned and used internally by a single entity without public accountability.
  3. It behooves the businesses to know what happened before them in the line of production of their components which make their goods. It allows the end customer to have more faith in the product as a whole, which is a positive for the business as well.

  1. Blockchain enables digital provenance by being an open source, data storage that is able to track transactions, auditing, supply chain verification to public.

  2. Normal databases are not decentralised and rely to heavily on “TRUST” as opposed to “Trust-less”
    verification.

  3. Digital provenance greatly benefits businesses that wish to demonstrate to transparency and openness. Clients, consumers & customers can trace the origins of a food source, employees, invoices, auditing, workforce and so much more which give consumers greater confidence in the business.

  1. How does blockchain enable digital provenance?

Because it is a decentralized database, blockchain acts as a ledger where all information can be stored without the ability to change it, plus it allows for real-time audits. This can be applied for financial transactions, joining the accounting layer to the transactional layer without them being two separate transactions. It would also be hugely beneficial in the supply chain field (track and trace).

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

Because a normal database is centralized and can be manipulated or deleted, it is not immutable; it doesn’t allow for real-time audits either. The whole process is cumbersome, inefficient and slow.

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

Blockchain can provide multiple benefits such as accountability, traceability, quality control, etc. making a business more efficient, agile and transparent.

  1. Blockchain enables digital provenance through a decentralized network of nodes who verify a keep a ledger of all transactions on the blockchain.

  2. A normal database can easily be changed by the operator of the centralized network. Thus, great trust must be placed in that centralized network to do the right thing.

  3. Provenance is a benefit because you can verify the person has the money or asset they purport to have. The check can’t bounce, the cash cant be counterfeit the painting or asset cant be a fake.

  1. Blockchain enables digital provenance by allowing data to be only added to database but cannot be removed from it. You don’t need to rely on somebody. It is trustless and new transactions are verified by network so its accurate and up to date.

  2. Because a normal database is not trustless. A normal database belongs to someone so you need to rely on someone for that accuracy. On the other hand, blockchain is public ledger, it is open to everyone but none can change old data.

  3. It is beneficial for many businesses because blockchain allow you to trace something fast, accurate and it is extremely transparent.

Blockchain allows digital provenance by keeping an open ledger of immutable data. This is verified by the whole network to provide factual digital provenance.

A normal database is centralized and controlled by a single party, which means that it can be manipulated and changed. unlike the blockchain which is decentralized.

They are able to track their products and remove the layer of trust between the supply chains. They also provide transparency to their customers without trying to convince them to trust them.

  1. How does blockchain enable digital provenance?
    Every transaction is stored on the blockchain and no one can delete anything. Every node has the full transaction history and every transaction has to be validated by every node in the blockchain.
  2. Why doesn’t a normal database bring the same provenance?
    Because if you have the rights you can delete, change or manipulate data on a normal database.
  3. Why is digital provenance such a great benefit to many businesses?
    Traceability is important for many business to track the provenience of their production or in the food business for instance to trace the ingredients of a food product.

  1. It makes all records publicly visible. There’s nowhere to hide incorrect information
  2. Lack of transparency
  3. Those providing products with higher quality materials and components will become known as better companies. - Downside: Crap ones have nowhere to hide.

  1. How does blockchain enable digital provenance?

Information can only be added, never removed. It acts as a public Ledger that verifies data between different computers. It’s traceable. “Don’t Trust, Verify!”

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

A normal database cannot verify with different computer nodes and information cab be falsified. Also, Blockchain is creating a global network that allows consensus.

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

It removes the need to audit and removes the need to trust. It makes everything very transparent.

  1. Records cannot be erased. Anyone can check anything. And anyone can add anything.
  2. A normal database requires trusting the database owner, and cannot do ad hock auditing.
  3. It’s easy for customers to verify or validate a business, they don’t have to trust any particular business, and business can prove, or disprove, they don’t have an issue.

  1. Transactions are stored on a public ledger to be verified with absolute transparency and replicated on each of the other ledgers.

  2. A normal database doesn’t bring the same provenance because they are centralized and they can alter the data. They may also not be transparent allowing corruption and manipulation to be possible.

  3. Digital provenance is a huge benefit to many businesses because it eliminates the need for trust. “Don’t trust, verify.”

  1. The Blockchain makes it trackable with public checks and balances created by each computer in the blockchain having their own copy of the “ledger” to check before any transaction can go through. Not only that nothing can be removed from the blockchain making it immutable.

  2. Because there is room for human error and tampering in other databases causing the need for trust instead of verification.

  3. Removes the need for trust by providing real time auditing.

1.Blockchain allows to store date in chronological order and is immutable. It is not possible to manipulate data that are “set in stone”.
2 .A normal database can be corrupted by people that see an opportunity. This is what happens in centralised organisation (government, banks,…). Even when audited sometimes normal database have been corrupted in order to acquire wealth or power. Blockchain is completely decentralised and doesn’t need an audit. The transaction itself is already considered self audited.
3.Companies can benefit greatly from the decentralisation because they are more transparent and reliable and they can save time and money because they don’t need to be audit. Moreover they can trace products and asset in general in a public ledger that is available to the public.

  2. A normal database isn’t transparant, you can’t see the transactions/data.
  3. Because you have an audit trail, you don’t have to trust but you can verify.

1.- By creating and inmutable and public chain that can be always checked.
2.- Normal databases are mutable, so they can be re-written, modified and manipulated.
3.- It ensures authenticity and transparency in a trustless environment without the need of third parties.
