Homework on Provenance - Questions

1 Blockchain enables digital provenance because it tracks down every transaction instantly. Also, any data from the past can’t change.

2 In a normal data base, someone behind it can change it up but on digital provenance, it’ll stay the same.

3 Digital provenance is a great benefit because if there are disputes with a customer, or a business partner, they can use digital provenance to solve their problem.

  1. Blockchain is a public ledger which means all transactions can traced and tracked. Provenance can trace and track all transactions on the blockchain public ledger. Provenance can then do ‘real time’ auditing. Which means that Provenance can audit transactions ‘in the present moment.’
  2. A normal database does not provide as much information as the Blockchain and it is not a public ledger like blockchain. So this means you cannot view transactions and trace them like you can in blockhain. Information can not be lost on blockchain. Blockchain is like a ‘digital stone.’ Whereas with a normal database much information can be lost if the system were to crash.
    3.Provenance is a financially efficient accounting layer with a transactional layer. This means that you can real time audit with Provenance yourself. You don’t need to have an accountant to do it for you.

  1. Blockchain gives you the ability to add data, but not remove or alter it. Since the block chain operates within a network of computers, everyone having access can see the transaction. Having these factors in place, allows one to verify the origin of a transaction or a process in developing a product, eliminating the need to trust an entity as to its origin.

  2. A normal database may accept data, but that data may be altered, which would make the information contained in the database unverifiable.

  3. Digital providence on the whole allows a business to run more efficiently by being able to conduct operations such as audits, process of the evolution of products, and general operations on the blockchain in real time through a verifiable process.

  1. Blockchain enables the ability to add data, but do not grant the access to delete or make changes. It built up trust which provides authenticity to the data as it is verified across the net.

  2. Normal database are centralised and data stored can be alter and delete. It will led to an inaccurate source of data. These factors also contributed to rising cases of money fraud.

  3. It provides great benefit due to the time efficiency and trust provided to the customers. Data can be accessed in real time while products information for e.g the shipment date from country to country can be access easily from the ledger.

  1. Blockchain enables digital provenance because it is decentralized and completely transparent, so transactions can be traced and tracked through “real time auditing”.

  2. Normal databases do not bring the same provenance because they are centralized and therefore can be manipulated and do not provide the same transparency.

  3. Digital provenance is a great benefit to businesses because it brings more transparency and efficiency to transactions and eliminates the need for trust. Customers don’t need to trust when they can verify instead.

In blockchains nothing can be deleted so its easy to track

in a normal database someone can eddit iformation

make it so we can heve less trust and more virifid information aboute bissnises

  1. Blockchain is a database where financial transactions can be added but not removed, where there is a network of computers all having a copy of this blockchain/ledger of financial transactions. Since transactions cannot be removed once recorded on the blockchain, it enables digital provenance to verify the existence of these transactions, and can trace the origin of where everything started and verified in a trustworthy way.
  2. A normal database doesn’t bring the same provenance because a normal database is centralized, and data can be manipulated without a network of computers to verify the data.
  3. Digital provenance is such a great benefit to many businesses because there is no need to trust and rely on others to prove that they have not deceived you in some way. You can see on the ledger where goods have been, how it was made, with what ingredients etc.

  1. How does blockchain enable digital provenance? Blockchain enables digital provenance through a multilateral democracy of consensus-based data flow _(ツ)_/¯
  2. Why doesn’t a normal database bring the same provenance? Normal databases depend on unilateral trust on people and/or archaic systems; thereby subject to manipulation and loss of integrity.
  3. Why is digital provenance such a great benefit to many businesses? Consumers will no longer have to vet companies and products through tedious means—requiring literacy / interpretation. Questioning Karens will be easily satiated with readily available authentication of information. Branding and marketing efforts no longer have to be focused on establishing this trust. This will streamline purchasing decisions and the establishment of new ventures. As my mom always tells me: the secret to success reducing the distance between thought and action.

  1. One can check the history of an item in realtime thanks to blockchain. Every transaction is written down on the blockchain and are immutable.

  2. Normal databases can be tampered with. One has to find a lot of trust for a normal database.

  3. The company and customers can verify where the history of their products thus reducing the need for building trust.

  1. How does blockchain enable digital provenance?
    a. The decentralised and immutable nature of the blockchain allows for digital provenance
    aa. Every node on the network can verify a transaction
    bb. Every transaction is written to the blockchain forever
  2. Why doesn’t a normal database bring the same provenance?
    a. Databases are usually centralised and not public
    b. Databases allow to add as well as delete information
    c. No one, except for the organisation controlling the database is able to verify its data integrity. Thus, trust is involved for other parties depending on the data stored in the database
    d. If the database is hacked or deleted, all of the information within is at risk
  3. Why is digital provenance such a great benefit to many businesses?
    a. It’s trustless and other parties are able to easily verify the integrity through (auditing) algorithms -> “Don’t trust, verify”

  1. How does blockchain enable digital provenance?

Due to its decentralization, all data are kept saved,secured and easy for verification.

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

Because a normal database is totally centralized and this a not secure in terms of security.

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

It’s efficient , reliable , low cost , more secured , transparent and totally decentralized.

  1. all transactions are fully tracable, can be tracked
  2. database does not provide all information in one
  3. no need for trust in a “third pary” - all can be directly verified

  1. Transactions written on the blockchain can only be added but not rmoved. It is a public ledger so that transactions can be verified.

  2. Transactions in a normal database can be erased or lost. There is a possiibilty to audit but the database is not decentralised or public as you will find in blockhain.

  3. It provides real-time auditing which could benefit business relying on accountancy, cutting cost…

3 Immutable data means need new records that take place of the old records. Auditing is built in.

How does blockchain enable digital provenance?
Blockchain is an open ledger that keeps track of all transactions. Everything is verified so there can be no manipulation of transactions from outside entities such as governments, banks, etc. No transaction can be removed from the ledger and everything can be verified.

Why doesn’t a normal database bring the same provenance?
A normal database can be manipulated. Transactions can be erased or lost from record. It is controlled by a central authority which can add or remove transactions without verification and little transparency.

Why is digital provenance such a great benefit to many businesses?
Business transactions can rely on verification instead of trust to complete transactions. Real time auditing and the elimination of “middle man” entities create a stronger relationship between businesses and clients.

  1. Blockchain enables digital provenance through built-in verification/audit of data by preventing data from being manipulated from one single node
  2. Other databases are either centralized or decentralized with a portion of data on each computer. For centralized databases, if one person were to hack into the main database, they could change the data and for decentralized through segmentation they could change the portion of data stored on that computer.
  3. Provenance through blockchain allows business not just financial institutions to lower overhead on man hours needed to track the reliability of the data. Since the data can be trusted through the blockchain trust procedure, there is no need to audit or spend hours verifying data.

1. How does block chain enable digital provenance?
The term provenance originates in the fine art world to describe a work of art or literature has documented evidence to prove the work has not been altered and is original. So when data provenance within a block chain database has been added it generates historical records for any piece of data. The block chain stores data provenance that contains changes made to data, where it originates and moves to, and who makes those changes over time. Essentially data provenance is showing your work in blockchain. This transparent record information can then be trusted for data validation and audit purposes.

2. Why doesn’t a normal database bring the same provenance?
A normal database is centralized that is controlled by a single entity that can be manipulated or changed. So, a block chain ledger provides a de-centralized location of the data where where information can only be added and not changed.

3. Why is digital provenance such a great benefit to many businesses?
Business can benefit from provenance by tracking both goods and services of goods in real time. Provenance enables businesses to easily collate their data, along with open data, and also verify data on an immutable data ledger on the a block chain. The block chain holds the most important information and allows anyone to check its validity.

1-tracks digital history in real time not to be able to be removed
2-because a normal database can be changed
3-first no need for paper verification which can be modified, second the immediacy of the info, third this creates incredible efficiency both time and value of quality of info. Therefore you can make more accurate decisions

  1. Because the blockchain cannot change, only be added to, is decentralized and on public computers around the work it is impossible to change. Allowing for the tracking of a number item or product All this ensures or enables provenance.

  2. a normal database can be changed, anyone with acmes to this database can change it. Because of its centralized location. it can be hacked now easily that a blockchain that is on thousands of computers that have the same file. also a normal database cannot do consensus, the approval of a change by other parties.

  3. because it verifies you can do audits every day or every minute if you want. the transaction is the accounting. it is trust-less you can trust that the the blockchain will Verify all the transactions and points that have been implemented into the ledger.
