  1. How does blockchain enable digital provenance?
    Blockchain enables digital provenance through a public ledger.

  2. Why doesn’t a normal database bring the same provenance?
    Normal data base doesn’t have a public ledger to see all the transactions and accounting.

  3. Why is digital provenance such a great benefit to many businesses?
    It brings honest and transparent information to the customers based on math and data, not opaque information provided by the retailer’s themselves. It makes it more efficient and potentially cheaper transactions.

Answers:
1- Trace and Track on public ledger
2- Normal database is not like digital stone (i.e. add only), it can be edited.
3- Takes the trust element out from the relationship.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
  2. Why doesn’t a normal database bring the same provenance?
  3. Why is digital provenance such a great benefit to many businesses?

1.Data is Verified by many users in the chain from the beggining by multiply copies of all records, which is giving tranaperancy.

2- The traces of normal data can be not trustable. Normal data can be changed, deleted, manipulated. The chain with normal can be not fully authorized.

3.One of its best benefits is that the provenance is traceble securely.
But what if the input data is incorrect at any stage?

Blockchain’s trustlessness enables providence. We no longer need to rely on either trust or, for example, accountants for auditing when blockchain encompasses transactions and accounting.

Normal database could be duplicated and unlike blockchain, there isn’t a network for verifications.

Using again the example of accounting, audits could be instant. This would make accountants obsolete. That, in turn, would cut down on cost and attain greater accuracy.

1.) A information or link get written in the Blockchain and another block gets generated over this information. If the information gets changed, the hash change. So u cannot changed the provenance.

2.) Because a normal database is owned and controlled by an central authority, therefore transactions can be deleted. Yout have to trust in the central authority in this kind of database.

3.) It solves the trust problem. As a company u give the thirds partys the ability to Verify instead of trust.

  1. How does blockchain enable digital provenance?
    In the current scenario, the actual transaction and accounting are dissociated. Companies then do the tedious task of auditing the accounts manually. In blockchain this can be done in Real time where every transaction is accounted and audited without human intervention and it is verified publicly.

  2. Why doesn’t a normal database bring the same provenance?
    This is trust based and is centrally governed. It is prone to manipulation and errors as well.

  3. Why is digital provenance such a great benefit to many businesses?
    It can save them much time and money by providing real time auditing.

  1. What does it mean when we say that in blockchain, consensus determines the truth?
    Each stakeholder verifies the claim made by the another in the eco-system there by eliminating the necessity of trust to determine what is true.

  2. How is this different from how truth is determined in a central database?
    In a central database there is no way for a buyer to communicate with the supplier of his supplier which creates a knowledge gap and in turn has to trust what his supplier claims. This database can be manipulated by one or more parties.

  1. Block chain enables digital provenance though its ledgers that show an origin trail.
  2. In normal databases we are able to update the data, but in blockchain shows the true status updates and trail of changes.
  3. Digital provenance allows us to not have to trust, we can verify. “Don’t trust, Verify”.

  1. Blockchain ensures digital provenance because the data stored in block chain cannot be modified, erased, or tampered with

  2. A normal database has a central system that is subject to manipulation, compromise data, etc.

  3. It is a great benefit to businesses because of the fact that transactions can be verified and accounted for and it is no longer an issue of trust (trustless; Don’t trust, verify)

  1. Block chains are a digital form of a public ledger, information can be entered into the blockchain but can not be manipulated. Anyone can check it.
  2. Normal Databases are centralized, they can be controlled, manipulated, deleted. There is also room for error. Blockchain can not be rewritten or lost.
    3.Removes the need for trust of the supply chain, provides traceability and transparency to the end consumer. Can provide real time Auditing at any time.

#1 Blockchain provides realtime audity and secure traceability and is immutable. All of which hands us a perfect partner to verify provenance .
#2 Normal database is centralised thus not immune for corruption
#3 Since digital provenance is fast ,reliable, and transparent , businesses can monitorf the chain of transport and reduce undeclarable losses by wastage and theft.
It also contributes massive gains in customer trust in the services and products, because the end user as wel can verify wat they are paying for.

  1. Data in blockchain are non-erasable and not auditable. Every single transaction is registered permanently and can be traced down to its source.
  2. A normal database cannot bring the same provenance because it is mostly controlled and interfered by human. A normal database is only a tool not a rule.
  3. Digital provenance is a great benefit to many businesses because it helps save time and unnecessary resources by eliminating double handling and errors in many areas. For example: bookkeeping to accounting.

  1. How does blockchain enable digital provenance?
    Blockchain enables provenance by providing the decentralized digital infrastructure with which everyone is able to track changes from the beginning to the end. It is designed in a way that you cant remove changes you can just add them.
  2. Why doesn’t a normal database bring the same provenance?
    Normal database can be edited blockchain cant be edited. Once the change is on blockchain it stays there forever. Normal database is also centralized and not distributed unlike blockchain.
  3. Why is digital provenance such a great benefit to many businesses?
    Because it offers businesses the technology that is able to track changes/history. Blockchain therefore removes the need for trust because history of a product can be verified and it can’t be manipulated.

  1. How does a blockchain enable digital provenance ?
    The Blockchain provides a transparent database which allows things such as products and financial transactions to be tracked and logged.
  2. Why doesn’t a normal database bring the same provenance ?
    A normal database relies completely on trust from one party to another, controlled by people, which can easily be manipulated in a negative or positive way to suit the needs of a business or person.
  3. Why is digital provenance such a great benefit to many businesses ?
    Many businesses rely on their supply chain to receive parts/goods, not knowing the products full history such as storage temperature or true origin. Digital provenance allows businesses to track everything ensuring they are receiving what they have been promised making the process completely transparent.

  1. How does blockchain enable digital provenance?
    It is transparent - open to view and transactions can be traced back through the blockchain.

  2. Why doesn’t a normal database bring the same provenance?
    It requires trust. It is opaque in the sense that you never really know what is happening and have to take the word of those you interact with. Outside middlemen are required to audit transactions.
    Information on the blockchain is immutable and once added is transparent and traceable.

  3. Why is digital provenance such a great benefit to many businesses?
    It cuts out the middle man, helping to keep costs down; it is instantaneous; it is transparent and verifiable, “don’t trust; verify”.

1-Creates a ledger, on many computers that are public, where all transactions can be verified but never changed
2-A normal database is not secure in that the information is provided by humans, and is based on trust, not a ledger that locks the data forever where it can not be changed
3-The digital data is locked into the blockchain after it is initially inputted. This information can be trusted to be the same because it cannot be altered.

  1. how does blockchain enable digital provenance. Provenance by definition is the ability to identify the existence of somethings existence. Blockchain enables each of us to not only validate an entities origin, but also validate its authenticity and quality. we can verify its existence along its entire path and trust the results.

  2. Why doesn’t a normal database bring the same provenance? even if a normal database was an open code source it could be controlled and manipulated without other sources monitoring, verifying and validating the information that is added and subtracted. with blockchain the information is added and verified by multiple sources that validate the information that is added.

  3. Why is digital provenance such a great benefit to many businesses? commerce and capitalism are not only built on need, but on trust. with so many supply options demand gravitates toward businesses that it trusts and identifies with. Provenance would allow complete transparency and businesses could create a clear advantage by allowing communities to identify with their products by understanding: where they originated, if they were pure, were they created with integrity and are the processes transparent. Provenance can and will ultimately improve the quality of our lives and the products we consume by forcing manufacturing to produce products that benefit the communities demanding them.
