Homework on Provenance - Questions

[mwollike]

1. Because all informations are in the transaction on all ledgers and it can not be changed or erased.
2. The third part can edit the data, its based on trust.
3. Everything is verified immidiately. No need for involving and trusting a third part or auditing.

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 Every step (transactoin) will be found on the ledger, thus if one step is missing the BC is broken and the transaction is not valid.
2 In general any database consists of independent entries, thus any entry can be changed without affecting the others.
3 All form of quality certification is obsolete, it is already implemented with the BC.

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. Blockchain doesn’t allow to remove input data, it is traceable and transparent.
2. Because normal database allows to remove, change or modify data.
3. Ledger will verify instantly. Blockchain can remove trust between individuals and organizations, so make it trustless, and also accurate.

1. Blockchain does not enable any alteration on data once they been stored on it and
   that gives digital provenance ability to track and verify any information stored.

2. On a normal database data can be easily accessible/ changed/ erased while this is
   not possible on blockchain.

3. Traceability, Transparency and real time Auditing.

[tvidebaek]

1. By having an open ledger where all transactions are written in stone and can never be erased or changed, and is open for all to verify.

2. A centralised database controlled by a single authority can be erased, changed, or manipulated and is therefore not as trustworthy as a blockchain.

3. It is a benefit for a business to be able to track and verify the origin of a transaction or a thing in the supply chain within seconds. Accounting can be partially automated, and much time is saved in auditing supply chains to improve quality control for example.

[DAN_B]

Q:How does blockchain enable digital provenance?
A:By being trustless.

Q:Why doesn’t a normal database bring the same provenance?
A: A normal database belongs to an entity that has to be trusted.

Q:Why is digital provenance such a great benefit to many businesses?
A:Digital provenance provides real time auditing increasing efficiency. No need for third party auditors.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?

It is a trust less system where you do not need to put trust in someone i.e banks, governments, companies. The blockchain is publicly available.

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

With a normal database you may have doubt as to where the information, transaction originated. Transactions are also hidden and trust is required.

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

With digital provenance you have an everlasting history of all transactions. These transactions are simply audit-able in real time. You have no doubt where the transaction originated from and you do not need to trust an entity.

[Simeon_Pickers]

How does blockchain enable digital provenance?
-> By removing the need for trust (ed middlemen) and hence allowing to verify the origin of a product or it’s ingredients, as well as all steps in a value / supply chain.

Why doesn’t a normal database bring the same provenance?
-> Because there would always be somebody in charge of centrally administrating the database, with the power to change DB entries at will.

Why is digital provenance such a great benefit to many businesses?
-> Digital provenance allows to be sure of any given information - unlike a “typical” digital file or information that can easily be copied, altered or tampered with. This can be of great benefit in auditing supply chains, accounting, financial information, intellectual property rights and many other business applications.

[Mark_Reeves]

How does blockchain enable digital provenance?
By creating a digital database that can only have information added not removed which is also 100% verified.
Why doesn’t a normal database bring the same provenance?
Databases are easily manipulated to suit the centralised agenda.
Why is digital provenance such a great benefit to many businesses?
To give the advantage of a ledger with complete traceability and security.

1. Blockchain enables digital provenance because it is a write only distributed ledger. No data can be removed. The transaction is the also the verification.

2. A normal database can be changed and may have garbage input

3. Digital provenance is a trustless and highly efficient system

[Sheleix]

1. How does blockchain enable digital provenance?

To achieve digital provenance the ledger needs to be transparent and non-modifiable. The blockchain enables it in the following way:

A-Ledger is public, therefore everyone can see the transactions and verify the starting and the ending point of the transaction.

B-Records cant be destroyed, which means what is done is done. This adds to integrity.

C-This ledger is a decentralized network, therefore you don’t need to trust the owner of the database to provide accurate information.

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

The normal database lacks both speed and trust. Since they are centrally managed, you need to trust that the information presented by the owner is true and accurate. Also, since it is centrally managed looking into the records is slower (requires permission from the owner and is not audited in real-time).

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

It provides the business with accurate and true data which enables better decision making. Also, real-time auditing and this tech in general will allow companies to cut costs on a lot of manual and low-efficient labor.

[Camila]

1.With Blockchain you are able to track each transaction and this one can not be changed or modified once it has been made. With this information you will be able to proof the provenance of each thing.

2. A normal databased can be changed or modify, which means that there are many possibilities to loose information.

3. Because it can be accessed and verified everywhere at any time.

@ThreeHeadsUp

if the data entered is non-valid, it can mess up the structure, make new additions impossible, completely destroy data

Yes that is correct but that is not the reason because the data is fake in the regard like someone faking balances. Someone can edit a regular database (even enterprise databases are mostly SQL databases) and fix the balance field to their advantage.
When databases become corrupt or destroyed is when someone breaks relations between tables or something similar. So a relational error, not a value stored in a specific field (for example balance).

@ThreeHeadsUp

so question, are there any enterprise databases that work like that, with advanced logging, decentralized, but NOT using blockchain? if so, can someone point me to one? and why would that be better than one using a blockchain approach?

I have heard there exist some proprietary hardware that ensure audit trail of data, however they are very expensive and I do not have any experience with them so I can’t help you out. Nor I don’t know the names of these products but are supposed to be used in medical industries. I also don’t know how reliable they really are.

1. How does blockchain enable digital provenance?

blockchain enables digital provenance by creating an uneditable public ledger of all transactions for a given item that can be verified via decentralized computers.

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

Because traditional databases allow for data to be updated or deleted.

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

Creates the potential for real-time auditing/tracking of goods and services in order to easily verify the quality and authenticity of transactions, products & resources which can save time and money as well as improve efficiency.

1. its written in stone (i.e. the blockchain) so you can track every transaction
2. outside of blockchain, most digital information can easily be copied or removed so you cannot trust the data
3. they can have a true accounting of each transaction. Can remove trust from the equation

Thank you Mauro ! Hope to be learning alot.

1). Blockchain enables digital provenance by utilizing the transparency of the public ledger, which can
be added to, and can not be changed once the data is on Blcokchain.

2). A normal database does not offer the same provenance because it’s not available to the public,
therefore nothing can actually be verified. Huge opportunity for data to be tampered with.

3). Digital provenance is a great benefit to businesses with honest and ethical standards. However,
businesses that practice dishonest and unethical standards probably won’t share the same views as
far as benefits. Lol

[cryptoforyou]

#1. it allows you to track transactions.

#2. because banks can make it look like one thing but in reality its completly different. in short: MANIPULATE. you have to put alot of trust.

#3. if you need to check something that you forgot, or double check that you transacted this, you can just check

[Josiah_Sugai]

1. Blockchain enables digital provenance by removing trust and allowing every addition of data/transaction to never be changed and always visible.

2. A normal database involves trust between companies or entities and aren’t transparent.

3. Digital provenance is such a benefit because companies do not have to rely on their suppliers “giving their word” but they can immediately verify and make sure that they are receiving exactly what they purchased.

Great homework Buck. Welcome to the academy!
