Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?

    • The very inherent characteristics of a blockchain provide the benefits. Trustless, Immutable, Chronological, Real-Time, and Easily monitored, Record/Database.
  2. Why doesn’t a normal database bring the same provenance?

    • Current systems are bulky, expensive and laden with friction. They cannot be trusted beyond the “reputation” of the admin governing the database because they can be easily altered and/or corrupted.
  3. Why is digital provenance such a great benefit to many businesses?

    • ? See question One?
    • Plus a chin can be constructed to display both a public and encrypted data.

  1. By providing information history for every single transaction that happened
  2. Because normal database can be edited and old information can be deleted and replaced. In Blockchain you can only add.
  3. It benefits them by simplifying audits and giving them reliable information without trusting 3rd parties

  1. How does blockchain enable digital provenance?

The blockchain is immutable and is a new public record. It can track a digital asset and all the parties who have owned it.

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

They are not decentralized across multiple parties and accessible by the parties in the transaction. Each party probably has their own database with duplicate records of the transaction.

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

One asset can be tracked across multiple businesses such as food going from farm to packer to distributor to grocery store to consumer to table.

Blockchain is fully transparent, therefore, transactions can be accessed and audited by everyone
Because unlike blockchain, data can be erased from ta data base
Provenance enables the transparency and eliminates the need for trust as - “don’t trust, verify!”

  1. How does blockchain enable digital provenance?

By being able to track all transactions in a decentralised database - ei. financial transactions, food ingredients etc

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

Because it is centralised, transactions can be removed and tempered with.

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

Because of its efficiency, data accuracy and transparency. It does remove trust.

A: By being able to track transactions/data in real time.

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

A: You can’t audit in real time transactions simultaneously like you can with digital provenance increasing efficiency.

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

A: Increases efficiency while taking out the trust in the process and replaces with verification.

  1. Blockchain provides a public ledger which things can only be added and not subtract. This allows for the provenance of each transaction, data input etc to be verified.

  2. Normal databases are centralized and require a great amount of trust in the database owner/holder.

  3. Allows for good business to thrive and makes it very difficult to hide or remove wrong doing. Integrity and transparency will prevail.

  1. The fact that the block chain provides an easy way to track data allows for the ultimate transparency of goods, assets ect. The digital ledger provides all that is needed to conduct truthful business.

  2. Simply put a “normal database” requires someone to trust the central authorities of what ever service is being provided. This can lead to the falsification of data. Leaving costumers at the mercy of these centralized authorities.

3.Being able to have a decentralized Ledger of untampered verifiable data allows for the trust less swap of information. Any business or individual conducting transfers of information in this manner can rest easy knowing they are not being led astray by a centralized authority that can easily tamper with sensitive data.

  1. Blockchain enables digital provenance through the verification of each step of a process. Once verified, the blockchain data can’t be modified, so everyone can trust it.

  2. A normal database can’t enable provenance because there’s no process by which to verify the data and ensure that hasn’t been changed.

  3. Digital provenance allows businesses to be sure that the data relating to their business is accurate, so much of the process of auditing is unnecessary.

  1. Blockchain has paved the way for provenance as there is no trust that needs to be placed, as the system consists of decentralized computers and therefore no human error can be made.
  2. Normal databases cannot bring the same provenance since they are not decentralized and there is no way to ensure no data has been changed/removed.
  3. It allows businesses to be more transparent with their methods allowing a marketing opportunity to attract customers who are conscious about what they buy and the companies they support.

  1. Blockchain enables digital provenance by keeping a transparent ledger of all of the historical data since its inception. This makes it easy to “Check the record” Its funny, that has always been my motto…wow!

  2. Most databases and their records are not public in centralized systems and there is no real way of proving that things have not been changed or tampered with. There has been a long history of burning or shredding the evidence of criminal activity. Blockchain eliminates that.

  3. It allows companies to appear upright to their customer base if they are willing to operate in a system that allows for an open review of their records. Also, it can assist productivity and curb losses if there is transparency between all of the cogs in the machine. Again, having the ability to “Check The Record” helps everyone involved.

  1. How does blockchain enable digital provenance?

It allows all transactions to be tracked on the blockchain in real time making it a trustless system.

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

Because generally a database is controlled by a few, is not decentralized & can not be traced. You can never fully trust a normal database as there is no way to verify.

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

Allows all transactions to be traced thus making the system trustless, plus it has the added benefit of making taxes easier. It will also help customers feel more at ease by knowing exactly where their products have come from (I’m thinking this would be really interesting in the food industry).

  1. How does blockchain enable digital provenance?

The blockchain is unchangeable and cannot be tampered with. Anyone is able to see the blockchain and verify whether a claim is true or false.

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

A normal database is changeable and can be covered up. It may not be on a public platform with many copies. Therefore, may not be verifiable.

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

Businesses and people can have confidence in processes or actions being done and don’t merely have to rely on trust. There is real time auditing along the blockchain.

  1. Blockchain uses a decentralized public ledger allowing anyone to trace and self-audit any transaction that is verified by millions of p2p connections on the Blockchain.

  2. Simply put, current databases can be modified internally or maliciously attacked. Digital provenance prevents this by storing all information on the Blockchain which is a much harder target and can not be modified without a majority consensus.

  3. Digital provenance allows for a completely trustless system between manufacturers, clients, and providers. In the future, digital provenance may improve efficiency and transparency within and outside companies. Digital provenance provides a way to track supply chains, customer orders, and other facets of useful information in near real time.

Through transparency, verifying and tracking data, keeping historical data with no records to be deleted so this would make a platform to be trusted.

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

Due to lack of verification, it’s a centralised system and it can be modified.

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

Organisation and Individuals can create a new way of business with real time data to be verified and audited. This enables a more reliable, efficient and transparent society.

    1. It keeps a record of every transaction that has ever taken place, thereby forming a decentralized ledger of all information stored in the transaction. This data can be accessed at any time by anyone, and is trustless in the sense that it has been verified independently by each node. As data cannot be edited or removed once added, you can rely on the information contained.
    1. A normal database has to be maintained by someone. You need to “trust” this entity to enter the information correctly, to never alter it or leave out parts. It is very hard to verify if all the contained information is correct. There is also a great degree of difficulty when it comes to automation (such as automated tax reports), as again, you need to “trust” that all income data has been entered correctly. With a blockchain you would see exactly where funds originated, where they were stored, and where they were spent.
    1. Digital provenance could potentially reduce costs of audits dramatically, as it can be done at any time “on demand” in a largely automated fashion. All data is stored decentralized. So no company hack, for example, could alter the data. This also could be used to build trust between the business and its clients.
