Homework on Provenance - Questions

[DazzaMac19]

1, Makes it Decentralized. Blockchain transaction process allows the ability to trace transactions track and audit in real time efficiently without influence of third party like corporation government or individual and for example. This process is immutable and can be trusted. Accounting transaction can be layered together with a purchase transaction establishing a record of purchase creating its history, on blockchain the data cant be changed.

2- There is a control authority or government involved. it can be manipulated. it cannot be trusted.

3,super efficient easily verified trust less and immutable perfect in my case for listing registering my Artworks as information cant be tampered with but can be tracked or other examples the verification of materials and ingredients are what they claim and come from where they claim they come from. All important when used as support as evidence if required or auditing and tracking.

1. Things can only be added to the blockchain and not removed.

2. The data base could be lost or entries removed.

3. Trust!

• How does blockchain enable digital provenance?

The blockchain enables digital provenance by providing real time auditing data where the transactions can be tracked in an open database (public ledger)

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

A normal database can not track the authenticity of those transactions based on a distributed unbiased network therefore relying on trust rather than provable fact.

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

Digital provenance can benefit businesses as they can track transactions, supplies(stock), orders etc. with great accuracy for example they can allow in the case of supplies a smart contract to automatically order more when a threshold of diminishing amount of supplies are reached without the risk of over ordering or being caught off-guard without the supplies because of the accuracy of the amount of supplies due to digital provenance.

1. Blockchain allows for real-time tracking and transparency of financial transactions which are verified or validated to be true on the blockchain.

2. A normal database can be altered and is done in separate parts like a transaction then accounting needs to be done for that transaction. Whereas on the blockchain it combines both into the same transaction which goes through a verification process and once validated receives its block on the chain for anyone to view as long as it is public.

3.Digital provenance can create more efficient tracking systems in the production, shipping, selling, inventory tracking, and financial reporting without error guaranteeing the end product or service being verified through the blockchain. Removes human error.

[razkole]

1. How does blockchain enable digital provenance?
   It provides a real-time public ledger of transactions.
2. Why doesn’t a normal database bring the same provenance?
   No real-time auditing, old databases, and be corrupted and have duplicate transactions.
3. Why is digital provenance such a great benefit to many businesses?
   real-time auditing, trustless transactions. savings.

[Krypto_Koala]

1. How does blockchain enable digital provenance?
   By creating an unchangeable chain of unchangeable events that are in a public ledger traceable to the parent event. This is what the blockchain is all starting from the genesis block.

2. Why doesn’t a normal database bring the same provenance?
   Normal databases can be altered and do not require proof of work to be initiated.

3. Why is digital provenance such a great benefit to many businesses?
   Traceability and verifiable authenticity by hashing algorithms is something that wasn’t used in a chain. It was more used as file specific stamps to verify if the file hadn’t been tampered with.

Blockchain allow data to be added, but data cannot be removed.
Provenance is simply the origin, and history of ownership. Since blockchain records, verifies, and confirms transactions in a way that it cannot be altered, or removed it can track all history of data on a particular item, or items.
On a normal database data can be removed or altered, by the central authority Blockchain is considered trustless, meaning it has no central authority with access to alter data.
Currently in many businesses you, if you are a manufacturer of virtually any item, in many cases you only have the word of your supplier that the products you are purchasing from them are authentic. Digital Provenance allows all items to be tracked, and verified so that they are completely trustless and you know the items you are purchasing are authentic. Real time auditing.

[aegis]

1. How does blockchain enable digital provenance?

Blockchain enables digital provenenace because a decentralized network of computers tracks transactions on a digital public ledger, thereby eliminating the need for trust. Information can easily be verified by anyone on the network.

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

Normal databases are centralized and can be altered/fabricated.

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

It alows for real-time auditing of transactions, real-time reporting, and helps eliminate the need for manually verifying the legitimacy of transactions.

[Gabriele]

1. Blockchain is based on an efficient network a connection of nodes with the result of ledger that is public, cannot be modified and is accessible for everyone. There’s no need to trust the participants since all transactions are tracked, can’t be erased and can be verified, therefore it’s not possible to hack it.

2. A normal database needs an intermediary, it’s not public nor based on the community network. It requires a certain trust and does have the qualities defined in point 1.

3. The lack of the need for trust, thanks to the help of a public ledger and of information that cannot be corrupted, allows for an efficient and fast system, without the need for accountants, having everything you need in the same pieces of information. For example, it is possible to know precisely which ingredients are present in a product and their conditions, knowing their movements and what procedures followed

[Bhavan]

1 How does blockchain enable digital provenance?
With the immutable public ledger,
where information can only be add.

2 Why doesn’t a normal database bring the same provenance
Because is centralised.

3 Why is digital provenance such a great benefit to many businesses?
Because it can be a certifications of provenance in the supply chain in the real economy.

[EGoncalves]

1 - Blockchain is a open database where you can add information but can´t remove and all the info is trackable.

2 - Because is centralized, you can manipulate the database.

3 - It provides no space for doubts and fundamentally trust, because you can verify the content.

[wkngui]

1. How does blockchain enable digital provenance?
   It enables digital provenance through a trustless system of having a public ledger that can never be erased (immutable) by any authority or government.

2. Why doesn’t a normal database bring the same provenance?
   A normal database can store the same information but can be amended, and can be lost in a system crash or database corruption.

3. Why is digital provenance such a great benefit to many businesses?
   Its a benefit because you can trace the trail up to the source, and do an audit. For instance, you can track where the source of food came from and possibly how it could have gone bad during the logistic movement.

[magcargar]

1. To know where and how much you’re getting and spending. It’s like a historial of a browser.
2. Because I think this database is pretending to have different results, and dude, we are talking about money.
3. It’s a real benefit to everyone because now you can see results and not to wait the people to steal or lie to you

[Onelove]

1. Blockchain enables digital provenance by creating a data base that can only be added to and not changed. This allows a group to audit the ownership of funds at anytime. Without block chain anyone could say they have an amount of currency and no one would be able to audit them.

2. A normal data base doesn’t bring the same provenance because the data can always be altered and changed. The security of blockchain allows everyone to see the exact origin.

3.Digital provenance is a great benefit to any business because it provides personal and individual security and power to be able to back trace anything that is placed into the database. The implications with blockchain is endless. With digital provenance companies can begin to build better relationships with other companies as well as their customer. If someone is worried about where their product comes from or who contributes to it, it will always be possibly to real time audit that product or company.

[Cryptojam]

1. Digital Provenance…record keeping and tracking. It’s an open public ledger that is confirmed accepted via conscious with other node’s ledger.
2. Normal database can be deleted and manipulated.
3. Benefit other businesses through transparency, traceability, and eliminates the need for blind trust.

[Gekiere]

1. How does blockchain enable digital provenance?

Blockchain enables digital provenance by adding each transaction. Not being able to remove any.

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

A normal database can be manipulated because account and transaction are not on one layer.

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

You can trust the blockchain data to track back the path of the product. This way you don’t have to trust the supplier for his word.

[Mizener01]

1. Blockchain enables digital provenance because there is no way to remove anything from the data base. Meaning every transaction that occurs and will occur in the future will be there forever making it impossible for anyone to fool the system and that is brand new to the internet.

2. A normal database cannot bring the same value because of the fact things are able to be removed. A normal database is also not decentralized and involves trusting a certain party or more. Blockchain eliminates all of that with its decentralization requiring no trust just transactions.

3. This is such a great asset to businesses because it is able to be a transaction that is instantly accounted for. Instead of having a transaction then needing to save receipts and having an accountant document them in a ledger, you simply make a transaction through the blockchain and it is already accounted for. Also on top of that it is impossible to fudge the transactions or remove any so everything is transparent almost removing the need for auditing at all.

[Tomahawk]

1. How does blockchain enable digital provenance?
Each block in blockchain contains information about something and this block can’t be removed (I assume it can’t be editted either). Blockchain is public so each information is traceable. Therefore it provides us possibilities like audititing or origin tracking of some product.

2. Why doesn’t a normal database bring the same provenance?
Because normal database is editable and not transparent and for example audit can’t be done in real time.

3. Why is digital provenance such a great benefit to many businesses?
I can see following benefits: Transparency, verification, real-time operating, origin tracking, saving money (for example saving money on external services like current audit companies).

[Tomahawk]

Also why is real-time auditing not possible for normal database? I can see a possibility of joining transaction and account data into one object in database and provide it online (or having a cloud based system). Correct me if I am wrong

[Ako1]

1. How does Blochchain enable digital Provenance?
   A: Blockchain, makes transactions tracable using Provenance, enables us to trustless and verify for our selves.

2. Why doesn’t a normal database bring the same provenance?
   A: A normal database can’t bring the same provenance because, the owner can erase some useful info, while in provenance it’s not possible.
