Homework on Provenance - Questions

  1. Blockchain enables digital provenance as all transactions are transparent and cannot be changed or deleted once they are in the chai.

  2. A normal database doesnt bring the same provenance as it it open to corruption as information can be deleted or changed.

  3. Digital provenance is a great benefit ti many businesses as it shows their integrity, regarding manufacturing, suppliers, ethics etc.

1-How does blockchain enable digital provenance?

Blockchain enables digital provenance by having a Public ledger where data can be seen in real-time of every transaction ever made on the blockchain.
Said data is immutable once inputted on the blockchain thus achieving digital provenance.

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

A normal database can’t achieve digital provenance because a normal database can be tampered with, Making the data inputted in said database unreliable and some cases untrusted.
And depending on how big the database needs to be, it can be really expensive.

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

Digital provenance can bring a lot of benefits to business because it’s fast and reliable, can be accessed via private or public channels and’s trustless. This way a company does not have to rely on 3rd party companies to audit its business. A company can audit itself in real-time because all data is available on the blockchain for real-time, untempered visualization.

  1. How does blockchain enable digital provenance?

~ It acts like a ledger (decentralized) it’s built so unique data that can be added but alterations can not be made to the blockchain, the history/ origin this is all tractable, with its own record but thats how trust is made and on the blockchain.

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

~Because a with a normal database it’ll require verification a centralized way so portions can be altered or wiped. The blockchain is immutable and this is not possible to work in a centralized way.

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

~The layers of data the can be created and applications of the blockchain will not change and applications are limitless thus the benefit increases efficiency, tractability and it creates more transparency.

  1. How does blockchain enable digital provenance?
    It is a a data base where you can put things but can not erase or change so it is impossible to commit fraud or cheat. And it is decentralised.
  2. Why doesn’t a normal database bring the same provenance?
    It can be changed-erased so it is open to manupulation therefore can not be trusted.
    And it is centralised meaning controlled by people (people who have access to change data)if needed, when needed.
  3. Why is digital provenance such a great benefit to many businesses?
    Firtly, it cuts down cost. Secondly makes things sheer. if you are a restaurant owner then you know exactly where your tomatoes come from when it was planted and when harvested. Wether if not the seeds were organic. All the details are being presented to you.

  1. Blockchain allows a transaction to be traced to a ledger or point of origin. The data are stored on the chain and are immutable.

  2. A normal database requires the trust of a central authority that can manipulate the data. The consumers of data have to trust that the central authority is providing accurate data. The blockchain takes the trust out of the equation.

  3. Customers can go back on the chain and know that the information they find has not been changed. Once the information is on the chain it will be there unchanged forever and can be verified by any party.

  1. Blockchain enables “provenance” because it records all transactions, does not remove any transactions from the database, and the Blockchain is public information that can be accessed by anyone.
  2. A normal database doesn’t bring the same “provenance” because information can be removed and it isn’t accessible by everyone.
  3. Digital provenance is a great benefit to many businesses because accounting and transactions are not separate but are interwoven. Therefore, verification and auditing of transactions can be done in real-time.

  1. How does blockchain enable digital provenance?
    Blockchain Ledger enables digital provenance by having transparent public transactions.

  2. Why doesn’t a normal database bring the same provenance?
    Becasue normal database is stored in a centralized location and contents can be
    changed and removed. Use of any data from a database relies on trusting that source.

  3. Why is digital provenance such a great benefit to many businesses?
    Because it creates transparency, they can track every transaction and dont lose
    information.

  1. Because it is a instant record created by a public ledger which one can only add data to.
  2. Because a normal database can be hacked and because its slow and also it relies on trust.
  3. Because it is trustless, capable of tracing the transactions back to point of origin, it can be public and private and because it’s fast.

  1. Blockchain enables digital provenance by creating a permanent public ledger for all transactions that is unable to be removed or copied is verified by the main network of computers.

  2. Normal databases rely on trust to dictate protocols and records. Provenance is dictated by complete transperency and the utmost detail in all protocols.

  3. Digital provenance is such a great benefit to many businesses because the trustless information reserve it provides is backed by verification and transperency.

  1. By being a public ledger accessible to anybody and anytime as long as they have the hardware and internet connection necessary for that as anybody can track and audit each transaction in real time. Transactions can not be removed from the data base.

  2. Because a normal data base is opaque and mutable and those who control it can add, modify and delete information from it to their pleasure.

  3. Because it provides them with the opportunity to show exactly how all processes part of their products and services have been at any given point in history. This can be very valuable to customers and clients and also increases efficiency of the resources used.

(1) Blockchain enables provenance because data can only be added and not removed. Everything is open source.
(2) A normal database can be changed. Where blockchain takes numerous validations in order for data to be verified.
(3) Digital provenance is a benefit to businesses in many ways. Instead of trusting someone’s word, data can be audited in real time. Plans can be made, decisions made upon verified data, and ultimately customers will be satisfied.

  1. How does Back chain enable digital providence? The blockchain is a network of computers in which data can only be added, and each transaction can be tracked and traced. Therefore the blockchain’s ability to track and trace allows for real time auditing, and that feature is what allows for digital provenance.

  2. Why doesn’t a normal database bring the same provenance? With a normal database information is not audited in real time, and cannot always be verified. Also information can be deleted from the normal database, but not from the blockchain.

  3. Why is digital provenance such a great benefit for many businesses? Because data can be verified, and the business don’t have to rely on trust, but can actually verify the veracity of the data. Also accounting functions can be done in real time and not periodic.

  • How does blockchain enable digital provenance?

Blockchain enables digital provenance by maintaining details of every transaction as it happens in the system. Its this ability which helps us to carry out real time audits if necessary. Once recorded, one cannot make alternations to these transactions and therefore they stay in the system forever.

  • Why doesn’t a normal database bring the same provenance?
    A normal database cannot bring provenance because of the additional capabilities of updates and deletes which are inherent to every database. These additional capabilities are prone to misuse and tampering and hence provenance may not be obtained using a normal database.

  • Why is digital provenance such a great benefit to many businesses?
    Digital provenance is beneficial to businesses to ensure they have a permanent record of each transaction which can be verified at any given point in time. It does not have to carry out expense audits or forensic investigation to find out the trail of a transaction post defacto.

Blockchain enables digital provenance by decentralizing transactions and making them transparent. This allows visibility of data entered every step of the way. Making it possible to trace from the beginning to end of a product assembly within a supply chain organization for example. No deletion or manipulation of data is possible within blockchain as each transaction is captured and copied in multiple computers for validation and transparency.

A normal database is centralized and controlled by an organization. That means it lacks transparency and =data can be manipulated by the organization. Also, hacking of data is possible on a few instances of a database within a few computers owner by the organization. But hacking on a decentralized system with the exact data stored in hundreds of block chain computers will be very difficult, especially if data from blockchain cannot be deleted,

Digital provenance is a great benefit to many businesses as many organizations rely on suppliers and partners to provide data and transactions that cannot be verified by a transparent system like blockchain.

  1. How does blockchain enable digital provenance?

A: As the ledgers is publicly traceable, we can check the supply chain or transaction histories on the net to check it’s origin.

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

A: Because not everyone can download all data in the public ledgers.

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

A: It reduces the costs of auditing as all data is publicly shown on the chain, people can verify everything on chain and don’t need to bet on trust.

  1. Blockchain allows to record all transactions in the public ledger thus gives us the traceability of each transaction recorded. Since ledger (database) maintained in network of each local machine, it can accept or reject the transaction entry if it is invalid.
    a. e.g Finance industry where auditing can happen real-time
    b. e.g. Food Industry - each and every ingredient within the product can be tracked in the blockchain so the consumer exactly knows the origin.

  2. Normal database can allow the transaction to be removed/delete. In blockchain - data can only be added but not removed.

  3. Traceability, create environment where customers trust the companies since information is available in public ledger to verify

Provenance Answers

  1. Blockchain is a public ledger. Public being all machines or nodes connected to the network can see all transactions and confirm all transaction timestamping each block. It’s this ability to track, trace, and only add data to the database that enables blockchains provenance.

  2. A normal database is centralized, and not immutable. You can add and remove data as you wish, this ledger or accounting is private and can be controlled by its owner. Making tracing, tracking, and origin uncertain.

  3. Digital provenance is an excellent benefit to businesses two examples being utilizing provenance you can maintain with certainty your product’s supply chain with countless optimizations. As well as check the integrity of any asset via real-time auditing.
