Homework on Provenance - Questions

[Connor]

1. How does blockchain enable digital provenance?

The ledger is public and decentralised meaning transactions are verified by a network as opposed to a central authority. Removes the need for trust and creates a more efficient system

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

A normal database is more susceptible to manipulation or alteration. It also cannot enable real time auditing and requires trust - unlike the blockchain

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

Can instantly verify real time data, transactions and improves efficiency massively.

[Abdullahsk]

1. being decentralised with inability to delete data and the ability for real time tracking for each transaction after being confirmed by different computers in the blockchain.
2. because it easy to miniplate data especially with lack of real time information.
3. bring lots of trust by enabling customer to verify by themselves. enable businesses to know more about their products and many more.

[Berrie]

1. By being decentralized we cannot change , duplicate or delete anything on the blockchain. The blockchain will verify the transactions in real-time by different computers that run their copy of the blockchain. Also the transactions are transparent to everyone who wants to see.
2. Normal databases can be manipulated and are in need of real time audits , while blockchain is decentralized and verified by the network.
3. Businesses aren’t relying anymore on the trust-factor , they can easily use blockchain to track all data from their goods. They can use it to track it how long it is being uphold and where its being uphold also can they implement other parameters of information like storage temp. , humidity , …

[AFatuliaj]

1. By using a public ledger
2. There is a public ledger instead of a central authority to verify stuff
3. It avoids the middle man, thus costs associated with it. Plus, allows for greater transparency in the supply chain

[thaddmaxx]

[Rahlord]

1. How does blockchain enable digital provenance?

With the public distributed ledger of blockchain technology you can trace back anything to it’s origin digitally.

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

A normal database is not normally distributed publicly and constantly audited. It can be manipulated by bad players.

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

You can reduce cost and exposure to bad provenances. You can prove the value of your product by a transparent provenance of it’s components.

[Victor_Krivitsky]

1. SInce blockchain is made to be public anyone can verify a transaction, for example, if I buy something at Mcdonalds, even though a burger doesn’t have a barcode you can attach the supplier information for each ingredient on a new scannable barcode on the receipt, it will link you to a blockchain of the transaction between the supplier for the exact batch of ingredients you’re eating .
2. It is not decentralized.
3. Eliminates trust in a positive way, more transparency to customers.

[Anni3]

1. How does blockchain enable digital provenance?
   Blockchain is akin to a digital stone where a completely traceable public ledger is viewable by everyone. The blockchain is stored on a network of computers(nodes) with have their own copy of the local database.
2. Why doesn’t a normal database bring the same provenance?
   The information added to the ledger cannot be edited nor deleted. It is immutable. Not one person, organization or entity can go in and erase or override the database.
3. Why is digital provenance such a great benefit to many businesses?
   The information is always accurate and trustworthy. Businesses can utilize this technology to audit and use metrics to verify a transaction, to accurately report/quantify an action or a source.

[Techman120]

1. How does blockchain enable digital provenance?
Blockchain enables digital provenance by allowing us to trace transactions in real time.

2. Why doesn’t a normal database bring the same provenance?
A normal database can be altered by the group that owns and controls it. In blockchain, no one has the ability to add to the whole blockchain without their change being verified by every other machine. Also, you can never remove a transaction from the blockchain - whereas in a database you can.

3. Why is digital provenance such a great benefit to many businesses?
Digital provenance removes any need for a business to trust its suppliers/partners. Also, their financial audits can be done routinely and remotely at any time.

[Micah_Rivetti]

1. How does blockchain enable digital provenance? Data cannot be edited or removed and is varified on a public open ledger by a network of computers making data difficult to corrupt.

2. Why doesn’t a normal database bring the same provenance? Data can be edited, removed or lost making it unreliable.

3. Why is digital provenance such a great benefit to many businesses? Confidence in records, live open transparency and improved efficiency

[KK_Cheah]

How does blockchain enable digital provenance?
-By providing a database in the form of a distributed ledger system of non-editable data. The network of the database gives it security, authenticity and provides a trustless platform which removes critical point of failures (eg organization, companies etc)

Why doesn’t a normal database bring the same provenance?
-The database is not structured in a way distributed ledgers are and the information is editable by whoever who owns a copy of the data as there is no network verification to verify the data

Why is digital provenance such a great benefit to many businesses?
-Bring real-time ad hoc tracking and clarity of information(transparency) and eliminating the idea of trusting what is promised but rather trusting in the immutable data.

[Troubadour]

1. Blockchain allows for a network of databases to publicly verify the authenticity of each transaction, all the while, tracking the whereabouts of the data

2. Conventional databases are centralized and overseen by a few, while blockchain is a public leger: anyone can verify!

3. It allows for total transparency for transactions, in real time, allowing for smoother accounting of funds, with total autonomy.

[KLhyr]

• How does blockchain enable digital provenance?
  By keeping an unalterable record of all transactions since the beginning to provide an accurate ledger of which wallets have how much currency.

• Why doesn’t a normal database bring the same provenance?
  Normal databases can be edited, so transactions could be altered or erased.

• Why is digital provenance such a great benefit to many businesses?
  It provides a chain of custody of assets so it can be proved how an asset has come to be where it currently is.

[Placebo]

1. How does blockchain enable digital provenance?
   Blockchain tracks indelibly, all changes of state or status of the items stored on the blockchain
2. Why doesn’t a normal database bring the same provenance?
   Because data can be deleted or modified. In a blockchain, data can only be added, so every change
   of state is stored forever, available to be examined and audited.
3. Why is digital provenance such a great benefit to many businesses?
   Because it removes reliance on trust. This is similar to what you see in crime dramas where “the
   chain of custody of evidence” must be preserved so the court can verify that nobody has tampered
   with the evidence. Blockchain lets you do that for free. You don’t need to hire accountants or audirots
   and it’s instant. Auditing and verification can be done in realtime. Every change to an account or an
   inventory item or an ingredient can be stored on the blockchain and nobody can corrupt the data
   once it is stored on the blockchain

[mahinder]

How does blockchain enable digital provenance?
Blockchain allows for tracking of all data being added to the blockchain via a public ledger and being verifiable.

Why doesn’t a normal database bring the same provenance?
A normal database is centralised and not public. You can also update/delete from a normal database.
A normal database is not trustless.

Why is digital provenance such a great benefit to many businesses?
It is trustless, everything is verified… there is no second guessing where things have come from, or if transaction details are correct or not

[Karim.A]

1. Blockchains enable digital provenance by creating a public ledger that cannot be changed. This means that everything can be tracked in real-time, and removes trust from the equation in a transaction.

2. A normal database can be edited, is not public, and does not have as many ways to verify accuracy.

3. Digital provenance is a great benefit to businesses because it streamlines many things. For example, accounting and auditing could be done automatically through the blockchain, or the supply chain could be tracked transparently. All this could increase value and reduce the cost for a business.

[ErikWithCrypto]

1. How does blockchain enable digital provenance?
Blockchain enables digital provenance by recording and verifying every transaction on a ledger. Essentially writing something “in stone” on the ledger for all to see and verify in real-time. It cant be removed and it cant be faked, such a tool removes the need for trust or ‘grey’ area that many banks and business dabble within. All transactions are real and verified by all computer networks ensuring transparency.

2. Why doesn’t a normal database bring the same provenance?
A normal database does not rely on a network of computers to verify and ensure transactions are real. It can be easily manipulated and changed by an individual to their liking. In this case we allow and ‘trust’ what ever centralised agency believes should be in the database by their own account not by an easily identifiable and transparent method such as blockchain.

3. Why is digital provenance such a great benefit to many businesses?
Digital provenance is such a beneficial tool to business because it allows for easily verifiable transactions. Transactions can be audited in real time removing the need for accountants at a later date to verify. Furthermore it is not only useful in the financial sense, blockchain can be adapted to work in various other sectors e.i ensuring that inventory stock are updated and managed at all times without the need for manually managing inventory OR can be used for companies to verify the ingredients of products be it food or apparel. Digital provenance solidifies the work of the company and ensures transparency.

[D08813]

1. How does blockchain enable digital provenance
   A. By creating a digital transaction history which can be verified in real time. Information on sender, reciever, amount stored digitally and cannot be modified.
2. Why doesn’t a normal database bring the same provenance?
   A. This can be edited by an Administrator (government). This creates a trustless system.
3. Why is digital provenance such a great benefit to many businesses?
   A. Can be used as an advertising tool with regards to origins of raw materials and manufacturing environments in the supply chain. Customers can check that companies are doing fair business which is a priority for many. Can reduce accountancy costs.

[enzinointhesky]

The Blockchain enables digital provenance by the transparency of the transactions.
Normal databases are not transparent.
It removes the the necessity of trust in the transactions or auditing.
