Homework on Provenance - Questions

  1. Data can only be added to the blockchain therefore can always be verified.

  2. Its owned buy a central authority and this requires trust.

  3. it allows trust to be removed from the equation.

  1. Through the blockchain, everything becomes traceable and trustless and transactions are not erasable, they remain in the blockchain forever.

  2. due to the fact that they act in a centralised system, where control and verification is one-sided and unilateral and where the trust of the clients is based.

  3. for the total transparency, safety and truthfulness of the operations like the origin of the goods or the ingredients used in food products.

  1. It creates chains of blocks that has data that is “written in stone”; data can not be removed only added. Another thing is that it is transparent, which allows anyone to see these transactions taking place in the network.

  2. Normal databases can change the data of past records; it is also not as transparent as a blockchain. This enables people to trust the companies in control of these databases. Whereas blockchain just needs verification no trust involved.

  3. It has the ability to track each transaction in real time auditing and allows businesses to track what they receive.

  1. How does blockchain enable digital provenance?
  • Using blockchain you’re able to track and verify transactions for example. This differs from the old way of doing it where a lot more trust is needed. Blockchains allow encrypted transactions to be open for auditing in real-time.
  1. Why doesn’t a normal database bring the same provenance?
  • Normal databases are not as complex as blockchain and are not able to track for example ingredients of transactions in the same way. In normal transactions a lot more trust is involved. Also, using a normal database that is centralized someone can go in and change things once inside the database, for example companies that use child labor can remove this fact, whislst using a decentralized database nothing can be removed only added.
  1. Why is digital provenance such a great benefit to many businesses?
  • If for example a food company uses digital provenance they could see exactly what ingredients are in the food that they get from other companies, otherwise they have to trust that what company 2 tells them is in the ingredients is 100% true. The customers can also verify what the company is saying, for example: If a company claims their food is organic it’s very easy to verify using blockchain technology.

  1. By being transparent.
  2. By doing not normal (not right) things to normal (honest) people.
  3. Don’t have to trust, it`s verified.

  1. How does blockchain enable digital provenance?

Blockchain allows all transactions to be traceable, a public ledger. We can verify the whole history, we can add data but not remove it, its immutable.

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

Because contrary to private blockchain, a normal database we can add and remove data, we can manipulate it.

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

Because it allows us to verify every transaction, do not trust, verify! Auditor role with a 100% accuracy. Customers will trust the product/business due to the transparency that this technology offers.

Blockchain is the data structure behind Bitcoin. Blockchain is a digital stone you can add to it, but never can remove any data from it. Provenance is a tracking system/ledger of all transactions. Also it is done in real time so it can be seen.

  1. Records cannot be erased. The blockchain is a decentralized network and every transaction is immutable. Because it is decentralized it is a public ledger where anyone can check and verify anything.

  2. Trust is involved between the database user and the data base owner. Data can be erased or lost if the centralized data base crashes compared to blockchain where its provenance is written on an open ledger that is a decentralized network.

  3. Businesses can now track origin and verify without trust in goods and services, in real time.

  1. Blockchain enables digital provenance by adding security and transparency to any online interaction.
  2. A normal database can be edited and isn’t verified by other databases whereas blockchain cannot be deleted and is verified.
  3. It adds reassurance and transparency between customers and B2B.

  1. How does blockchain enable digital provenance?
    Answer: Blockchain enables digital provenance by providing an immutable, verifiable, trustless, record of provenance while reducing labour and increasing speed and accuracy of auditing without the need for physical counts/verification of items/documents.

  2. Why doesn’t a normal database bring the same provenance?
    Answer: A normal database is unable to provide the same provenance because it is not immutable, often centralized and private, and unable to provide the same level of ‘real-time’ auditing.

  3. Why is digital provenance such a great benefit to many businesses?
    Answer: It is such a great benefit because for many reasons:
    -ability to audit in real time
    -reduces labour and increases efficiency while decreasing costs
    -is a verifiable, immutable, permanent record.

  1. Network of computers/nodes hold and verify records of digital transactions in blocks that can only be written once and can not be removed.
    2.Normal data bases allows create, update, read, delete operations while block chain doesn’t allow delete 3. Every transaction can be traced back to the origin, no central authority involved in financial transactions that removes lot of inefficiencies due to a trust involved in transactions.

  1. How does blockchain enable digital provenance?
    Because all transaction which are recorded on the blockchain are immutable.

  2. Why doesn’t a normal database bring the same provenance?
    Because from database you can delete files, change them, not like with blockchain.

  3. Why is digital provenance such a great benefit to many businesses?
    Because you can see where is money going, is it spent like suppose to. You can audit businesses in real time.

  1. In simple terms, blockchain technology enables digital provenance by removing the “trust” element from business and replaces it with “truth” (through mathematical and algorithmic means).

  2. Normal databases don’t bring the same form of provenance as the data can easily be manipulated and fraudulent activities have the potential of occurring. Blockchain technology precludes this by having data “set in stone”. Once data has been transcribed onto the blockchain, it cannot be removed.

  3. Digital provenance benefits business for a number of reasons. Firstly, real-time auditing. This allows companies to be audited more effectively without the inefficiencies that come from manually having to sort through physical and/or digital receipts and transactions. Secondly, it can greatly benefit businesses through supply-chain tracking. This allows b2b and b2c companies to be more transparent with their clients/consumers. An example of this would be understanding the ingredients of a sandwich you ordered, you will know exactly where the grain has been grown, which types of grains has been used, where the grains were processed into bread, and what have you.

Please give me any feedback, comments, corrections :grin:

1.- because the transactions on the blockchain can´t be erased and you can track and audit each transaction made.
2.- a normal database is centralized and can be modified/changed with out group consensus, so you have to trust
3.- because they dont have to trust on the other person, they just have to verify

  1. Blockchain enables provenance because it is a database structured in a way where you can write and not remove any transactions. It is real time records accessible to the public and private.

  2. Normal databases do not bring the same provenance because they are centralized. They can be changed and modified. Also access is not available to everyone.

  3. Provenance is a great benefit to businesses because it takes out the trust. Everything is available which makes everything transparent.

  1. Blockchain provides full transaction transparency which allows the ability to trace all transactions back to the original.

  2. Databases are not immutable and have greater energy demands

  3. Businesses benefit from fast and secure transactions that exclude third parties

  1. Digital provenance is enabled by blockchain adoption thanks to the fact that it is a public ledger and it enables real-time auditing.

2.Traditional databases aren’t immutable and involve trust in the database owner, plus it isn’t usually public such as in the financial or food industries.

  1. It gives the opportunity to customers to make more conscious and less-trust-needed choices, therefore if the quality is adequate to the needs then the demand follows.

1. How does blockchain enable digital provenance?
Only able to add data and cannot remove data from the blockchain.
The blockchain is copied over many machines making it easier to trace back to the correct data
2. Why doesn’t a normal database bring the same provenance?
a normal data base allows you to remove information and add causing issues with tracking if something is true in the past
3. Why is digital provenance such a great benefit to many businesses?
allows customers to see and track what they are receiving as well with the company to track what is going out to the consumers and removing that trust factor
