1.How does blockchain enable digital provenance?
Enable digital provenance by making transactions trusted and verified
2.Why doesn’t a normal database bring the same provenance?
Can not bring same provenance because is centralized and data can be removed.
3.Why is digital provenance such a great benefit to many businesses?
Because it is able to fight cheating and data manipulation

  1. Because the blockchain is decentralised open source and every transaction or event is registered on the open ledger, therefore, everyone can see and monitor it in real time.
  2. Because normal database is centralised and someone has control over the events and transactions that’s happening in the database. They can choose wether to verify, alter or delete events or transactions from the database.
  3. Because it’s transparent. Every party has a set of rules they have to follow to participate in transaction or event that cannot be changed, avoided or cheated. This, however, builds trust to the system and takes out the 3rd party who would play the role of referee.

  1. Blockchains enable provenance if their immutable ledgers are available to the participants (this can be a private or a public blockchain). By ensuring that ledgers are distributed to a sufficient number of nodes in the network to secure against a 51% attack in its own particular context, users of the blockchain can ensure that the transaction on the network are valid.

  2. Normal databases allow administrators to edit and delete records. This means that you cannot trust the entries in the database were not tampered with.

  3. I can decrease costs associated with audits. It can also open the business to being more trusted by its consumers. It can also hold governments and companies accountable for tenders/government contracts or whatever space where there is a greater need for transparency and accountability in the public sphere.

  • How does blockchain enable digital provenance?

Blockchain is an open ledger, it’s only possible to add transactions and impossible to remove therefore the provenance can be tracked and traced to the source.

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

A normal database can’t bring same provenance since on any data base besides blockchain (as far as I know) data can be edited and removed.

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

Due to the fact that it gives full transparency it is much easier to track trace and Trust by verifying. In my opinion it can also help business with low budget to keep and maintain everything via the provenance without huge human resources.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?

In terms of accounting, the details of a transaction are included in the on the blockchain along with the amounts. I.e. who made the transaction and to whom. So accounting becomes almost automatic when using a blockchain. In terms of tracking of goods, the immutable quality of the blockchain makes it possible to have true provenance from point of origin to manufacturer to consumer.

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

A normal database is centralized, and therefore some individual or entity may edit it. Therefore it is not immutable and therefore can’t necessarily be trusted to provide true provenance.

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

digital provenance allows business to counteract fraud and counterfeiting and also confirm with certainty to their customers that the products they sell are what they say they are. It also let’s them do their accounting very easily.

  1. blockchain enables digital provenance by tracking every transaction that has been made in real-time, making it possible for anyone to see every transaction that has been made.

  2. A normal database doesn’t bring the same provenance because you can’t be 100% sure of the content that is in a normal database. The only way is to give it your trust and hope that the information that has been given is not wrong.

  3. It’s a great benefit for many companies because they don’t need to trust anyone, they just have to verify everything by themselves. It gives them the possibility to track every single step of some activities at any given time for example: where the product is from, what countries the product was in and in what condition the product is in.

  • How does blockchain enable digital provenance?
    By allowing anyone to track/trace the historical transactions on a public ledger and having a network of computer verify the transactions.

  • Why doesn’t a normal database bring the same provenance?
    Because a normal database can be edited but Blockchain is a digital stone and does not allow for editing past historical data.

  • Why is digital provenance such a great benefit to many businesses?
    So we can live in a “trustless” environment and get rid of many middlemen and make biz much more efficient!

  1. How does blockchain enable digital provenance?

The blockchain is a decentralized permanent ledger. The details can be verified by anyone at any time.

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

A normal database is centralized and relies on trust.

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

It promotes better business relationships. No need to trust when you can verify. Businesses will hold themselves to a higher standard and customers will in turn get a better product or end result.

  1. Blockain proved tha ability to tracke any transaction live from beging to the current state of the traced item like ingredientes used on food, or the materials used to produes the end product without. Therefore anyone can verifify where and how the end product was made instead of trusting what the company said.
  2. Norma database can be easy modified by the company or super user. Unlike the blockchain tha can only be writen but not be manipulated otherwise.
  3. It allows businesses to know in real-time what is going in their supply chain and quickly course correct any issues, preventing losing a lot of money due to finding out problems a month after the fact.

1/ How does BlockChain enable digital provenance…!?
The BlockChain is a Decentralized Public Ledger, & digital provenance is achieved with real time auditing ( every second ).
2/ Why doesn’t a normal database bring the same provenance…!?
A normal database is centralized & prone to manipulation, third party, bad actors…( Hackers, Corruption ) etc:
3/ Why is digital provenance such a great benefit to many businesses…!?
Well for example, between manufacturer & supplier, points in the supply chain can be checked, it brings efficiency to the processes.

Answer

  1. Blockchain is to be seen as a database where you only can add information and not delete, the blockchain is decentralized meaning there is a network of independent computers verifying every transaction.
  2. A normal database can be changed and altered/manipulated the blockchain cant.
  3. It allows transactions to be transparent and instantly verified by both parties

  1. Every blockchain transaction is stored on public ledger and can be verified at any given time.
  2. Conventional database(whether on it site or in the cloud) can manipulated from inside or outside.
  3. Real-time audit, no 3rd party needed, fairly easy to use compare to a regular DB

  1. Blockchain allows anyone to openly see the source and origin of digital data or information. While at the same time no one can alter or make changes to the data or information.
  2. Normal databases hide digital data and information from the general public. In fear that it would be altered or changed in some way.
  3. Digital provenance allows business’s trace the origin of data and eliminates trust from one another. Don’t trust, verify.

  1. Every transaction will be written on a blockchain and no one can remove it. Therefore, it would be easier to verify previous transactions. We would not need to trust but only verify.
  2. Because everything can be removed in a normal database.
    3.Because we can now audit with real-time activities instead of using history.

  1. Blockchain provides a digital provenance by keeping track of every transaction, without altering any.

  2. A normal database does not bring provenance because a particular entry can be altered or deleted.

  3. On the blockchain, a transaction cannot be altered. As such it serves as a proof for every transaction. So all transactions can be verified without any records being altered. This will give a factual account for every business holder.

  1. How does blockchain enable digital provenance?
    By putting all information on the blockchain it securely stores the information - making it audit-able, unchangeable and open. Blockchain could ensure provenance of materials used by manufacturers is known by having it on the ledger.

  2. Why doesn’t a normal database bring the same provenance?
    Centralized databases are more susceptible to fraud and cyberattacks as data is located in a centralized server or in a cloud. Thus also making it harder to track items through the supply chain and eventually on to the consumer. Centralized databases are not always visible, available or trusted.

  3. Why is digital provenance such a great benefit to many businesses?
    It can provide end-to-end visibility, eliminate process inefficiencies, reduce cycle time, create new opportunities to deliver value for customers, build deeper supplier relations and deliver information quickly that can be acted on.

Because it delivers very much needed credibility (of the company) in the eyes of customers. Transparency in the supply chain shows all the steps the product had made to come to customer.

  • How does blockchain enable digital provenance?
    It is a publicly accessible ledger, a network of computers verify the transactions, it cannot be altered
  • Why doesn’t a normal database bring the same provenance?
    A normal Database is typically not public or decentralised , it could also perhaps be altered and it might not be possible to verify that someone tried to change the record
  • Why is digital provenance such a great benefit to many businesses?
    Because they don’t have to trust their e.g. suppliers, they can verify all information if the want / have to

It is able to store data and information in such a way that they can’t be tampered with. Therefore you don’t need to just trust an entity, you can verify it.
Why doesn’t a normal database bring the same provenance?
Normal databases can be changed/manipulated or the entity storing the data in the database might be biased.
Why is digital provenance such a great benefit to many businesses?
It takes away the uncertainty regarding the origin of commodities. It prevents unethical practices. It can make sure that the quality is garanteed.
