Homework on Provenance - Questions

  1. It makes it so that anyone can verify the origin of a transaction on the blockchain (digital database) to ensure it is valid without the need for a third party and a wait time and what not…?
  2. A normal database does not allow for public viewing of each transaction without permission which is not guaranteed.
  3. Digital provenance brings the ability to verify product quality for commercial purposed, ensures a level of security to records that is otherwise unreachable by todays methods to all businesses and provides the ability to audit in real time by allowing access to the blockchain.

1- By being a trustless decentralized database.
2- Because there is a central authority that can manipulate the data, in Blockchain to manipulate the data you will need to have control of the 51% of the entire network.
3- Real-time auditing and transaction and accounting in one single layer.

  1. Blockchain enables digital provenance through transparency of ledger entries.

  2. Normal databases do not have the same provenance as blockchains since there is the possibility they can be edited at later dates; the auditing of normal databases is also separate from the transaction that takes place.

  3. Digital provenance benefits businesses since they can offer customers total transparency of supply chains, meaning confidence that the business is doing what is says it is doing.

  1. Blockchain enables Digital Provenance by ensuring transactions are verified without the parties trusting each other. This means that you are to trust no one on the blockchain, instead, verify everything.
  2. A normal database does not bring the same provenance because there is no transparency, it is opaque and can be manipulated by the owner of the database or whoever has control of it.
  3. With Digital Provenance businesses can now verify every transaction and get tasks like financial auditing done in real time on a minute per minute basis. You no longer have to wait for someone to bring you just any information without you verifying its integrity.

My answers:

  1. Blockchain enables digital provenance thru add every data to the ledger and it is not possible to remove any data. There are many “copys” of the database so it is decentralized.

  2. A normal database isn’t open to averybody. You need permission to look into this data. Blockchain is open for everybody.

  3. You can be audited remotely,

  1. How does blockchain enable digital provenance?
    Blockchain acts as a public Ledger to track transactions and data cannot be deleted.

  2. Why doesn’t a normal database bring the same provenance?
    Current system requires a regulator and is manually written or tracked. There is no transparency and can be manipulated or edited by the database owner.

  3. Why is digital provenance such a great benefit to many businesses?
    Automation of data. Free trustless transactions and ease of verification and auditing. Security and transparency of data.

  1. How does blockchain enable digital provenance?
    The creator embeds a digital signature which shows authenticity and records the information on the blockchain. It is decentralized so instead of trusting it, you have to verify it.
  2. Why doesn’t a normal database bring the same provenance?
    There is a central authority that controls it, there is need of more trust.
  3. Why is digital provenance such a great benefit to many businesses?
    This can increase user satisfaction as the users can check the open source blockchain themselves to see the proof of transaction, it is easy to trace as everything is visible to the public.

  1. How does blockchain enable digital provenance?
    By allowing data to be added but not removed and by publicizing the “ledger.”
  2. Why doesn’t a normal database bring the same provenance?
    It’s centralized, which makes it vulnerable to malicious activity and error.
  3. Why is digital provenance such a great benefit to many businesses?
    It removes trust and therefore creates transparency, combines both accounting and transaction data in the same space, and allows faster auditing.

  1. How does blockchain enable digital provenance?
    The Blockchain enables digital provenance by being able to verify every step of the transaction as all the data is stored on the Blockchain.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database is centralized which means that it is more susceptible to hackers and online attacks as there is one point of central point of power.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is a great benefit to many businesses because it allows them to not have to trust the other business they are working with.

How does blockchain enable digital provenance?
Digital provenance is enabled by blockchain through a permanent & public ledger which can be easily verified & require no trust.

Why doesn’t a normal database bring the same provenance?
Normal databases have a central private record of transactions that can be modified or manipulated by the central authority or an outside hack.

Why is digital provenance such a great benefit to many businesses?
Any business that requires proof of activity or transactions can benefit from this digital provenance. For example buying/selling used cars. Often an inspection can be done to get an idea of the kind of care/maintenance done to the car throughout its life. However even in the rare case that the owner keeps a detailed record of work done, there is no way to verify this information. If a car could be connected to the blockchain & require an update to the blockchain every time it is serviced, there would be a public, verifiable record throughout the cars life.

Hmmm… multi-million dollar idea?

  1. How does blockchain enable digital provenance?
    By being decentrilized and working on concensus between many different nodes to create the permanent ledger and thereby setting the correct data in stone while ignoring any erroneous data.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database, even one with multiple backups, reside in one place and is therefore vulnerable to being tampered with or destroyed by bad actors inside the organization and outside hackers.

  3. Why is digital provenance such a great benefit to many businesses?
    With a blockchain style ledger opposed to a centralized database said company could be assured that the ledger was accurate & would have no need for extensive audits, lawyers, accountants ect. This trust in the ledger is also a huge benefit to all the people & organizations that do business with said company.

  1. Blockchain keeps permanent records and improve the transparency. Because blockchain is decentralized no one has control over the data, and no one can change the information or database.

  2. Most databases are centralized, the company could alter the data and there is little transparency if none.Consumers just have to trust the company and its data.

  3. Because is encourages verifiable data by allowing others independent or direct access to it, and gives the possibility of real-time audits.

A1. Blockchain enables digital provenance by being immutable, open source and decentralised code. Meaning it is not run by a central server, it is spread over many around the world, making it very hard to shut down or control. It is also immutable which means you cannot make changes to it once the transaction or whatever has been added to the blockchain has been confirmed, also it is open source code which means that anyone can access the blockchain and verify the transactions taken place on the blockchain, therefore there is no need to trust anyone or what they say when you can look at the blockchain and verify certain transactions yourself.

A2.A normal database is centralised and usually not open source, which means they usually lack the transparency that blockchain offers, Being centralised also means the information is stored on one server or cloud storage which makes it vulnerable to being hacked or shutdown, The information is also controlled by the centralised entity which they choose what they do with information, whether they want to change or get rid of it.

A3.Improved traceability, real time audits done digitally, verifiable trust with blockchain which can be shared with business partners and customers alike.

  1. How does blockchain enable digital provenance? Blockchain enables digital provenance by combining the auditing and transaction processes together. Since in traditional provenance the organisations are working based on the information provided there is trust involved ie., organisations need to make judgements based on the information provided by other party. But with Blockhain human judgements are eliminated instead the transactions can be verified since all the transactions are public.
  2. Why doesn’t a normal database bring the same provenance? A normal database cannot bring the same provenance because not all transactions are public and the data can be tampered. Auditing firms will have to trust the information provided to them.
  3. Why is digital provenance such a great benefit to many businesses? Digital provenance is a great benefit to many businesses because it eliminates the need for auditing. Because the organisations can verify the source by themselves since all transactions are public.

    Because every transaction gets stored in the blockchain, like a public ledger
  2. Why doesn’t a normal database bring the same provenance?
    Because a normal database allows you to erase data.
  3. Why is digital provenance such a great benefit to many businesses?
    Because you don’t need someone else to trust, the blockchain had a built-in verify system that allows you to get rid of this middle man.

  1. Blockchain enables digital provenance due two properties it posses. which are its a public ledge meaning anyone can view all transactions on the public in real time. Also the blockchain is an immutable database you and only add information to it but you cannot remove information already stored in it.
  2. Information in a normal database can be edited and the database isn’t public.
  3. Digital provenance get rid of trust issues. It makes businesses transparent and permit for real time audit.
