Homework on Provenance - Questions

  1. Blockchain enables digital provenance because it is trustless and you can trace/track any transaction.
  2. A normal database doesn’t bring the same provenance because data can be updated or deleted, whereas blockchain is immutable.
  3. Digital provenance is a great benefit to many businesses because they can verify the source of their products so consumers can trust supplier information.

  1. The blockchain is a ledger, which by its very nature allows for provenance to be established.
  2. A blockchain is a decentralised ledger, making it immutable, as forgeries would not find consensus.
  3. Digital provenance allows organisations and individuals to trust that a product is genuine, without the need to trust the supplier - don’t trust, verify.

How does blockchain enable digital provenance?

  • blockchain enable digital provenance by having all the information / transactions recorded and cannot be amend/deleted etc. blockchain is an open ledger where every information can be traced

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

  • old and centralize (cloud storage/server/etc.), data easily can be crashed/amend/deleted, information can be controlled.

Why is digital provenance such a great benefit to many businesses?
-not depending to other bodies for auditing, trustless, . It create a record purely of proof that is not base on the trust. 100% legit

  1. by being capable of tracing all transactions.
  2. in a normal database, accounting layer is separate from transaction layer. A conventional database has a limitation in terms of being able to track all transactions and being completely auditable.
  3. Transparent and efficient

  1. Blockchain enables digital provenance by being trustless and immutable, it is without centralised authority, totally decentralised with network of computers, what goes in, cant come out
  2. Normal database usually controlled by one entitity, can be hacked, changed, it is controlled by centralised authority, therefore trusted by it.
  3. It can be tracked in real time, audited real time. There is no trust involved, information cant be changed. Makes it so easy to see history of product/service with a full confidence of being true. Easy to verify

  1. How does blockchain enable digital provenance?

By making sure that all the data that is input in the blockchain cannot be removed or deleted. it acts like a digital stone. That way all transactions can be traced. hence people would trust those transactions

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

because data in a blockchain cannot be removed or altered. Therefore every transaction can be traced and relied upon as true as opposed to other data bases

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

The technology will bring much more trust in the form of verified evidence which can be achieved through an audit trail of transactions which is verifiable.

  1. How does blockchain enable digital provenance?

By having all transactions/entries in blockchain public and immutable one can trace back where it came from. This is provenance

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

The main issue with normal database is that they are centralized so trusting the one who created it is paramount.

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

Digital provenance can give guarantees on quality of a business. Imagine a company has implement the tracking of its whole supply chain in blockchain. Customers can easily verify claims of the company in every step of the product cycle.

  1. Blockchain enables digital provenance by providing blocks of code that authenticate the origin of a transaction.

  2. A normal database doesn’t bring the same provenance because the multiple processes in authentication is separate and there’s a “trust” being held between all of the different parties.

  3. It’s a benefit because there is more transparency between the parties involved with creating the product and it provides a more reliable source of information for the customers.

1. How does blockchain enable digital provenance?
It enables digital provenance since blockchain is a decentralized database that stores all transactions chronologically (ledger) that can’t be altered (immutable) and are publicly available.
2. Why doesn’t a normal database bring the same provenance?
Because a normal database is centralized. The owner of the DB can modify entries. Therefore, it does not meet the immutability property of the blockchain.
3. Why is digital provenance such a great benefit to many businesses?
Digital provenance is a great benefit to many businesses because they don’t need to trust other companies. They can trace and verify all transactions on the blockchain (public availability and transparency).

  • How does blockchain enable digital provenance?
    Blockchain enables digital provenance because financial transactions are traceable in real-time. It acts as a digital stone where the network of computes in the blockchain can add transactions and it’s impossible to remove transactions. It is also not controlled by any organization or individual making it fully decentralized and gives power to the people using it because anyone can verify transactions instead of putting “trust” in people or organizations.
  • Why doesn’t a normal database bring the same provenance?
    Because a normal database cannot provide transaction details real-time to anyone. It may also be run by an organization or a government and a normal database would enable anyone adding and deleting data.
  • Why is digital provenance such a great benefit to many businesses?
    Digital provenance is a great benefit to many businesses because it promotes transparency of transactions and enables people to verify transactions.

A1.Blockchain reserves the data of the transaction, and it can not be altered. Each node of the blockchain verifies the transactions.

A2. In a normal database, a transaction is saved to a centralised database and thus it is open for manipulation.

A3. Digital provenance removes the need for trust, because it allowes to verify the transactions in real time. Accounting and transaction are seamingless.

Blockchain allows provenance by making an open source verifiable public ledger which can be audited and verified without having to rely on trusting the normal organizational opaque systems. It brings a more efficient, reliable and accurate method of auditing and tracking transactions, movements and data sets.

  1. As you said Ivan blockchain is a digital stone, and the information on the blockchain can’t be erased or modified. So it’s perfect for real time auditing and hence, blockchain totally enables the option of digital Provences for public (masses).

  2. Because the normal database is not secure as blockchain(ledger). So normal databases is useless for provenance.

3.Digital provenance has the biggest and greatest benefit for businesses, because the customers don’t need to have blind trust on the products, they can verify any thing at any time they want.

  1. By not allowing the removal of entries, this ensures that there is traceability from start of the chain till current block
  2. An admin/user can do edits/deletes to change the current state without knowing the history
  3. The knowledge that no can change the information once it has been added.

  1. Blockchain Is traceable and track able. Every transactions is recorded and is viewable. Every transaction that is written on it could never be erased. By storing each step of the chain you can verify the origin of each entry or product.

  2. A normal database is centralized so it is vulnerable to attack. This is easily achieved by attacking the central point

  3. Digital provenance creates a ‘trust-less’ environment that automatically sends data. This allows us to remove trust from the equation and not be reliant on centralized bodies that could fail or be dishonest.

  1. How does blockchain enable digital provenance?
    Blockchain enables digital provenance because the data is stored on a public ledger therefore all the information is available to anyone at any moment for verification.

  2. Why doesn’t a normal database bring the same provenance?
    Normal database doesn’t bring the same provenance because it has a central point of failure as did Byzantine General Problem, therefore it does not consist of benefits like a public ledger.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is great because it is cost efficient, fast, immutable, non-reversible and public therefore verified easily.

  1. How does blockchain enable digital provenance?
    Blockchain gives every stakeholder the power to verify every transaction done on the blockchain network.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database is by itself. It is not chained together like blockchain technology , normal database can be changed at will by its user.

  3. Why is digital provenance such a great benefit to many businesses?
    Because every stakeholder will be able to verify ( using blockchain technology) the involved transactions or trace the products which they purchased. Digital provenance prevents any form of 3rd party manipulation like vaccines suppliers changing their mind to ship vaccines supplies to country A, when a wealthier country B offers to pay triple the price to intercept vaccines supplies.

#1 I believe it is because the blockchain is visible to the public and recorded on many different computers.
#2 a normal database is controlled by one entity typically in one location who can easily change the information stored on it.
#3 provenance allows for real time audits without disruption of regular business.

  1. How does blockchain enable digital provenance?
    Blockchain is a PUBLIC ledger that gives the ability to audit transactions in REAL time (every second)

  2. Why doesn’t a normal database bring the same provenance?
    The current normal database does not store ALL the information in one place and is not auditable in real time causing many opportunities for lost and/or delayed information.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is such a great benefit to businesses and individuals, because it eliminates the need to trust. No need to trust when you can verify the information immediately.
