Homework on Provenance - Questions

[ollitheorca]

1. How does blockchain enable digital provenance?

• You can’t delete data from a blockchain. You have a network of computers/servers to verify each transaction made on the blockchain to secure transactions are not edited and copied. In this case, the blockchain would ignore the “fake” transaction.

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

• Because all CRUD operations are available in a normal database.

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

• A business will be capable of tracking every single transaction/step in a supply chain, either a package delivery process, or currency transactions, or any other type of process. This way trustlessness is achieved! Meaning that a business does not need to trust that certain steps are completed correctly or in a certain, specific way. They simply verify the data in the blockchain.

Don’t trust - Verify!

1. Blockchain enables digital provenance by storing all transactional data in to a permanent public database that can’t be altered with and is visible for everyone at anytime.
2. A normal database can be altered by people that would benefit from certain changes. Is based on trust.
3. There would be less errors, audits would be easier no more trust issues.

[andreypoe]

1. Due to the immutability of data on the blockchain anybody can verify the provenance of a transaction in real-time.

2. A normal database can be corrupted by the owner or third parties that have access to data.

3. Digital provenance eliminates the TRUST between the players or associates that are working together on the blockchain by letting each parts to verify each others data.

[mchoeti]

1. How does blockchain enable digital provenance?

Simple said. All the information are stored IN the BLOCKCHAIN which is available from the public.

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

Because a person with enough admin rights can change it.

In a Blockchain you cannot convince people. It is all about fundamentals

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

You always know where your transaction has gone.

There is always a way to proove it for the government, because it is in the blockchain

which enables real time auditing

1. Blockchain enables digital provenance by providing a public transactional ledger that information can only be added to and not deleted. Thus preserving the origin of any transaction from anytime, from anywhere.

2. I normal database does not bring the same provenance because those databases are centralized and controlled by particular individuals/organizations. Information within these databases can usually be changed or deleted from the database quite easily. This leads to a system of trusting others are providing you with the correct information, and on the next level, that the information they think is correct is indeed factual and not messed around with in any way(cannot verify in some databases if something has been edited)

3.Digital provenance is a great benefit to many businesses because they no longer have to win you over or swindle you. These businesses can now only supply factual information within their database that proves(verifies) their business’ trustworthiness and can help illustrate their success/power that could benefit you as a client. in short, it lets business show their work and success, rather than tell a fable about it.

1. Blockchain enables digital provenance because once data has been added it cannot be removed or altered. It is all public and anyone can access it at anytime.

2. A normal database has an owner, some sort of authority maintaining it and you need to trust them. In a normal database you can also change or remove data.

3. It allows real-time audit of transactions and traceability. They can verify instead of trust.

[DNenzel]

1. Through the immutable decentralized ledger. All the provenance data is captured on chain and is verifiable
2. Normal DBs are not immutable and require trust. They require middle men
3. Digital, decentralized provenance reduces the cost and improves the security of transactions.

[Judith]

1. Blockchain stores the transactions in the public ledger which can not be mutated, information is publicly verifiable in what transactions and accounts were made.
2. A database stores information central and interlocked users totally dependant on trusting others for the truthfulness of shared information because the lack of verification
3. The prior constraint of verifiable not mutable transparent information in any process or chain will emerge business transactions due to the easily overcome threshold for actors to interact not being conservative and expel waste in between the process / chain.

[SeanW]

1. How does blockchain enable digital provenance?
   It embeds a digital signature which demonstrates authenticity and records that information on a blockchain.

2. Why doesn’t a normal database bring the same provenance?
   A normal database can be altered and can have misleading or false data on it.

3. Why is digital provenance such a great benefit to many businesses?
   It provides a transparent environment for all to see.

[PragmaticAlan]

1. How does blockchain enable digital provenance?
   Each block in the chain is immuatable (cannot be changed). Blocks build on one another and additions are verified by multiple distinct nodes so protected from tampering and enabling people/computers to follow a trail from one block to another.

2. Why doesn’t a normal database bring the same provenance?
   A database can be altered, is centrally controlled and accessible by many with limited change control (not trustless).

3. Why is digital provenance such a great benefit to many businesses?
   The ledger is public so anyone can look at it, query it and understand it – in real-time. This brings transparency and the ability to audit a trusted source without the need to hire expensive auditors (e.g. Ivans’ example of PWC, Deloitte etc). You will be able to audit(and verify) blockchains at the touch of a button, repeatedly without manual intervention saving time, effort and frankly, tedious exercises.

Q1. How does blockchain enable digital provenance?
A1. Provenance enables businesses or people to easily collate their data, along with open data, and also verify key information on an immutable data ledger called a blockchain. The blockchain holds the most important information and allows anyone to check its validity, you can add infromation on a Blockchain but not remove it.

Q2: Why doesn’t a normal database bring the same provenance?
A2: A normal database dont give you the same infromation like a blockchain. On a normal database you can not track all information and you can change the infromation on that database, and is based on trust that the information are correct.

Q3: Why is digital provenance such a great benefit to many businesses?
A3: With digital provenance you remove trust, the working process is faster and much safer, and you save Money and Time.

[Ivan_Colourblind]

Q: How does blockchain enable digital provenance?
A: Being publicly available and decentralized, could be real time audited and only write not remove possible. Being trust less as depending on math.
Q: Why doesn’t a normal database bring the same provenance?
A: Can be maleficent behavior causing disruption and false data, not for all eyes.
Q: Why is digital provenance such a great benefit to many businesses?
A: Leaving it to transparency and honesty of the produce ingredients genuine.

[Ribr]

1. How does blockchain enable digital provenance
   A blockchain ledger records all transactions in real time. All informations that is stored can’t be changed or manipulated. Database are open to public.

2. Why doesn’t a normal database bring the same provenance?
   A normal database is centralised and can easily be manipulated and changed.

3. Why is digital provenance such a great benefit to many businesses?
   It provides realtime audit and transparency, reliable, efficient.

[dmarou]

1. Blockchain functions as an open ledger, tracking every transaction-enabling digital provenance.

2. In normal databases, transactions can be removed/edited/deleted. If there is a crash/wipe, data can be lost forever.

3. Digital provenance is a benefit because it provides real time auditing, not based on trust, but instead verification.

[Mil_Pasos]

1 - Blockchain can enable digital Provenance due to it being a public ledger and recording each transaction it gets in chronological order across multiple nodes, which can not be altered.

2 - A normal Database is centralized, therefore the information can be interrupted or changed by the owner, where with Blockchain it is immutable and more reliant on verification instead of trust.

3 - It is beneficial to businesses as they no longer require to get third party audits, fully transparent and has real time tracking advantages which could be implemented in supply chains.

[DylanHepworth]

1. How does blockchain enable digital provenance?
   Blockchain technology stores and records all transactions that occur on the network. This is what creates digital provenance and allows for significantly more accurate and efficient accounting and tracking. The information is accurate in real-time and is immutable.

2. Why doesn’t a normal database bring the same provenance?
   Blockchain is different because it is all done with trustlessness. The mathematics of the code and protocols ensure precise and reliable information. The blockchain cannot be tampered with via one computer and works on consensus, so the information cannot be manipulated. However, a normal database is not like this because the information can easily be changed and manipulated from one computer, and therefore does not create the same provenance.

3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance makes tasks much more efficient because with it, it is possible to track everything with exact precision, in real-time, and it can be done trustless. The computers and code verifies the transactions and makes things accurate and fast. Businesses can now know for sure that their auditing and tracking is done correctly, and they can also do this faster and more location-independent than ever before.

[Han5en]

1.) Everything that is written in a blockchain, is like written in a stone. You can only add data, but not remove it from the blockchain. Everyone can check/prove the transactions, its an open ledger.

2.) Because a normal database is always controlled by a person or company, its not decentralized.

3.) Because you dont had to trust someone.

[Gutto13]

1. Blockchain enables digital provenance by creating a public decentralized ledger that updates in real time and is verified by each computer on the blockchain everytime the ledger is updated.
2. A normal database doesn’t provide the same provenance because it is not decentralized and is not verified by multiple computers. You essentially need to trust the single database that all information is correct.
3. Digital provenance is a great benefit to many businesses because they no longer need to “trust” any given entity or database for information they hope is correct. By implementing blockchain they are able to have a “trustless” decentralized system that verifies, in real time, the information they need.

[jblazquez]

1. First of all, blockchain works as a database that allows you to add information, but that information can’t be removed or changed from the database. This guarantees the transparency of the transactions. Second of all, every transaction can be tracked and audited in real time. This allows everyone to follow in real time what’s happening with any transaction, products or supplies. Finally, everything in the blockchain is public to anyone. This can make it easy to see what’s happening with one transaction.

2. The normal database can’t be audited in real time. Besides, if someone wants to see or audit that information, that person or company, has to research in a differents database to obtain what they need. Also, the information that they may find could have been modified in order to lied about it.

3. Digital provenance enables businesses to innovate in the way their business grows. By doing it, businesses can reach a new level of transparency and can be more efficient in many processes that are slow, inefficient or uncompetitive. Furthermore the digital provenance can put them in one of the top positions of the industry.

[BoBandy]

A1: By being a completely transparent system which allows for straight forward tracking to origin. Plus the ‘you can add, but not remove’ factor.

A2: Because a non-blockchain datanase isn’t publicly transparent in the same way and therefore not directly traceable.

A3: Because of my favorite life motto: Don’t trust - verify. When trust is removed from the equasion or rather replaced by actual verification of information, a whole layer of uncertainty is removed and you know if you are working on solid ground. Transparancy is key to long lasting business (or any) relationships.
