Homework on Provenance - Questions

[PetraH]

Hopefully I poste it at right place. (?)
1.How does blockchain enable digital provenance?
All the information about product are in a blockchain and are immutable. It can be access publicly.

2.Why doesn’t a normal database bring the same provenance?
Normal database is not decentrilazed and fraud can happen and validity of data cannot be easily verified, it is not trustless.

3.Why is digital provenance such a great benefit to many businesses
reduce the overall cost of writing and running databases
Nothing has to be on paper, data are transparent for customers

1. Once blockchain transactions are accepted they can not be changed. They are also available to the public and can be verified by anyone.

2. Normal databases aren’t usually available to the public, who could verify the information. And of course the data in normal databases can be altered.

3. Because there is no need for trust anymore. They can always check the actual origin and condition of the products up to date. Everything can be verified. What happens on blockchain, stays on blockchain

cool i will totally check this out many thanks

1. Blockchain enables digital provenance by creating a trustless ledger that cannot be deleted and nothing may be removed from it. It allows for full transparency and transmission of truth through a chain of transactions. There are countless uses where truthfulness needs to be verified but all parties cannot necessarily trust each other
2. A normal database doesn’t bring the same provenance because it is not distributed and trustless, and because a normal database will allow for deletion and modification of the data stored within it whereas a blockchain will only allow additions to its code.
3. Digital provenance can be such a great benefit to many businesses because then businesses can automate auditing and can trust the information that they are operating better because there is no singular point of weakness that needs to be trusted in the system, everything is transparent and trustless. Blockchain also combines the accounting layer and transactional layer onto the same system and therefore makes it more efficient and easier to do business without additional clunkiness or bureaucratic weight.

1. Blockchain enables digital provenance by eliminating trust. One does not have to only trust the provider but can actually verify the veracity of the information thanks to blockchain. Hence reducing to 0 the possibility of a lie in the information chain.

2. Blockchain kind of acts as a group of people that know the exact same information and when a person tells a lie, all the other people know that that person is lying because they know everything about each other, in the exact same way. Instead of the information going through a “telephone game”, the blockchain makes sure that that info is accurate thus the matter of provenance is not going to be a problem when someone ones to dig into it. A normal database can not help you track in the most accurate way because it’s information it is not verified as accurately as in a blockchain. Plus once you upload some info into the blockchain you can no longer erase it.

3. If businesses use digital provenance they agree with being completely transparent regarding the information they provide. One business can not lie anymore because the customer can track every move they make. So it is great for businesses that are being sincere with what they are actually stating that they’re selling but may be troublesome for businesses that have some hidden spots in the timeline of accuracy.

1. By creating a verifiable and immutable record of transactions, blockchain allows for an open source traceability of origin.
2. With the problems created by the inability to evidence the integrity of datasets, companies must rely on a network of trust to qualify the provenance of goods or transactions.
3. Verifiable digital provenance allows for a security in exchanges that is not currently provided by the classical model. An end to end, transparent account of exchanges removes the need for trust in a supply chain and has zero tolerance for inauthenticity.

1. Since data cannot be removed from blockchain, it is possible to trace the origin, path, and many other things relating to a transaction/product. Since it cannot be altered, there is only a pure, true, and accurate history recorded on blockchain.

2. A regular database can be altered, and is usually centralized where as blockchain is entirely public and has many copies of it being hosted from different computers. It is also unalterable.

3. It removes requiring trusting suppliers, and sources. Businesses will be able to see exactly what they are receiving and from where. It also helps businesses verify their products.

1. How does blockchain enable digital provenance?

   Blockchain stores the entire chain of information regarding the item and has a verifiable history of
   every transaction that can be traced but cannot be modified or altered in any way.

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

   Because any normal (centralized) database can be subject to change or manipulated by the entities who control it.

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

   Because it removes the need for trust and third-party audits as all the information is readily available and verifiable. Moreover, as this information is securely stored and cannot be changed, the businesses will have a much easier time handling accounting and legal matters should they arise.

[MPer]

1)Because it allows all records and/or trascations to be public and therefore tracked and traced.
2)A normal db can be edited; therefore cannot be trusted unless it’s audited; also a normal db is typically centralized.
3) Because they will be able to trace and track anything in their supply chain and this will happend due to the verification that is possible.

Benefits of Using Blockchain

1. How does blockchain enable digital provenance?
   Blockchain is like a database that is open to the public, easily tracked, permanent, verifiable and transparent in that anyone can examine the contents of each transaction. It enables digital provenance as you can verify and trace any transaction from the very last transaction to the very first one (the Genesis Block) that Satoshi created at the very beginning of the chain.

2. Why doesn’t a normal database bring the same provenance?
   Unlike blockchain technology, normal databases can be manipulated and changed.

3. Why is digital provenance such a great benefit to many businesses?
   Because blockchains are decentralized and hosted on thousands of computers, the transactions are verifiable in an automated fashion and do not require “trust” as the standard business accounting practices do.

[Pufferfish]

1- The blockchain is a ledger where we can trace the transaction history of products, services, goods, etc.

2- A normal database is centralized and controlled by a trusted entity.

3- There is no need to trust when you can verify on the blockchain ledger.

[Craig]

1. How does blockchain enable digital provenance?
   Blockchain can track every transaction in real time. Every transaction is added to the block chain and cannot be removed or changed.
2. Why doesn’t a normal database bring the same provenance?
   Information can be changed, deleted or manipulated.
3. Why is digital provenance such a great benefit to many businesses?
   Faith in accurate data base and hold business accountable for all transaction. Instills trust in the product or origination of the data.

[ChloeN]

• How does blockchain enable digital provenance? Because blockchain does not allow to delete or change the old records and only add new records.

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

Because admin of normal database can change the old data in the database

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

Because it provides the tracing to origin of the things that matter to the business and also bring many other benefits like save time and money for the businesses to keep track of things they want to keep track if they do not use blockchain technology.

1). Blockchain enables digital provenance by secure traceability of certificates and other salient information in supply chains. Provenance enables every physical product to come with a digital ‘passport’ that proves authenticity and origin.

2). A normal database is centralized and data can be erased or edited.

3). Digital provenance is a great benefit to the operations of the shipping chains businesses.
Interoperable platforms that eliminates double spending.
Guaranteed continuity because of the elimination of any central operatorensures inclusiveness and longevity.

[benmoto]

1. Blockchaiin enable digital provenance by real time auditing (trace and track).

2. A normal database is centralized, not a public ledger and can be altered or deleted. A normal database cannot be audited in real time.

3. Digital provenance is such a great benefit to many business because it combines accounting and transaction in same database. It is also a great benefit for many businesses since they no longer have to rely on trust.

[CameronW]

1. How does blockchain enable digital provenance?
   Blockchain is a digital public ledger of data which cannot be altered or removed
2. Why doesn’t a normal database bring the same provenance?
   Normal databases can be altered by anyone who has a copy and is not verifiable
3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance allows for transparency in the supply chain therefore less resources have to be allocated to auditing it, while also removing any reliance on trust.

[DearPhumi]

1.Blockchain is a database with all the transactions which can only be added but not removed.
100%trustworthy/verifiable that enables digital provenance to track anything anytime anywhere.
2.Normal database isn’t transparent, we don’t have full control and need to trust whoever is in charge.
3.You will be able to track everything, no questions nor trust needed. everything can be verified

[Ivana1329]

1. Blockchain enables digital provenance by keeping track / gaining a trail of the origin of product (i.e: Bitcoin, ingredients, auditing, manufacturing).

2)A normal database is input and can be controlled/altered. The blockchain can not be altered and is a digital imprint.

3)Businesses will be able to focus on different areas and spend less time on things such as inventory/ auditing.

[mhamour]

Homework on Provenance:
1- By Having all transactions/Information stored in one place where they cannot be modified or removed.

2- Normal DB is centralized and it can be modified, delete records from it , and if it fails the possibility of losing the data is high.

3- Because each transaction that happens and stored can be traced and tracked in real-time plus the benefit of real-time auditing where it will save time

[cryptochef]

1. It enables it by being a transparent and verifiable system (public ledger) where dishonesty it’s not an option. All transactions are easily checked and tracked in the database, making it available for all users.
2. Because it is based on trust that can’t be verified. Not traceable, and easily manipulated by third parties.
3. Because it helps being transparent & tax authorities-friendly. Easily traced transactions and publicly displayed accounts, allowing Real Time Auditing.
