Homework on Provenance - Questions

[Valentino]

1. every transaction is written in the blockchain and can be verified but not changed
2. a normal database can be changed, you can remove and add information
3. because provenence of products or goods can be tracked and traced from the origin.

[rln8312]

1. Because transactions are traceable and unable to be destroyed the users of the blockchain can verify rather than trust.
2. Normal databases can be deleted and manipulated.
3. By eliminating trust and verifying transactions the business can increase the quality of communication.

omework 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. How does blockchain enable digital provenance?
   Bitcoin commits changes to the blockchain with cryptographic proof of work that can’t be changed once committed.

2. Why doesn’t a normal database bring the same provenance?
   Traditional databases are centralized and may therefore be changed by the database administrator unlike blockchain.

3. Why is digital provenance such a great benefit to many businesses?
   Complete transaction history is preserved and may be easily referenced with high degrees of confidence.

[Ahmad_Abd_Allah]

1. How does blockchain enable digital provenance?
   Because of its decentralized and immutable nature, the records on blockchain database is permanent.

2. Why doesn’t a normal database bring the same provenance?
   A normal centralized database is based on trust to the maker, in a decentralized blockchain database trust is replaced by verification of the “transactions” by all nodes in the chain database.

3. Why is digital provenance such a great benefit to many businesses?
   Don’t trust but verify. it’s trustless. There is no central authority needed.

[Bondix]

1. because all transactions are written in the ledger and you cant remove them.
2. because its not decentralized
3. because its decentralized and trustless where you just verify

[pau01]

1. By recoding transactions in a permanent way, also alterations to such transactions are not possible.
2. transactions in regular database can be altered, by third parties.
3. It insures authenticity and quality of transactions.

[JamesR]

1. How does blockchain enable digital provenance?
   By electronically recording transactions into a public ledger, where the data is irremovable, e.g. as in etched in stone, and the public has visibility to these transactions in order to validate or confirm its proof.

2. Why doesn’t a normal database bring the same provenance? A normal database, would be one where a central authority could easily manipulate data to overcome shortcomings or in worst case scenarios create gross negligence and easily cover their mistakes.

3. Why is digital provenance such a great benefit to many businesses? Its creates an environment where anyone with access to the blockchain can validate transactions and confirm the validity of the entity making these transactions.

[petertreepeter]

1. Every transaction is stored in blockchain and cannot be removed therefore it is simple to track and trace any transaction as the blockchain is an open source.
2. Normal database is editable so there is no trust.
3. Anyone can audit anytime they please just about anything.

[haris2210]

1. Since blockchain being a public ledger, the transactions are transparent and it is immutable.
2. Normal database has a central authority governing them and is mutable.
3. It helps in Real Time Auditing.

[Lecocrypt]

1. every transaction is recorded on the blockchain ledger and cannot be removed. With provenance, each product can be tracked (i.e. locations it has been, quality of the product at each location, source of product).
2. The information cannot be removed, so it can never be destroyed because it is published on the blockchain.
3. real-time auditing and accurate tracability, also levels the playing field because hopefully small businesses will be able to use these products as well.

1. How does blockchain enable digital provenance?
   digital provenance is important in tracking some things origins or records of ownership , or track the entire history supply chains and blockchain provides a decentralized database or verifiable digital ledger that tracks all transaction history using an add only property hence you can’t change, amend, and duplicate or manipulate anything that is recorded on the blockchain. its records and transaction are immutable providing real time auditing and trackability

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

normal database doesn’t bring the same provenance due to the fact that it is not distributed to all parties and agreed upon in real-time. it is controlled by a central authority or administrator that can amend, change, duplicate, and delete with no consensus. there is no trust or verifiable way to confirm the data is correct or not due to the centralization of authority that can alter anything in the database any time

3. Why is digital provenance such a great benefit to many businesses?
   users can trust supplier’s information is correct as a ledger can be created from the seed of the supply chain to end user with the ability to provide granular details and provides a digital passport for individual products enabling identification of authentic or counterfeit item
   it takes away the need to trust anyone you deal with and business can followup and verify the history orign of information along the supply chain and can be confident as abusiness that what you are selling or providing is what u claim it is and can prove it
   it increases customer satisfaction becance they can verify any claims
   It is beneficial as it encourages verifiable trust by allowing others independent or direct access to full ledger or data starting from the origin to shelf. It also reduces traceability time from days to seconds.

[Fima]

1. How does blockchain enable digital provenance?
   A. By having to gain a consensus from all nodes to verify transactions on a public ledger which is the blockchain.
2. Why doesn’t a normal database bring the same provenance?
   A. Because normal databases are centralized which means they are the only node and are generally private.
3. Why is digital provenance such a great benefit to many businesses?
   A. It is a benefit to business because it’s trackable and trust less.

[modestbateman]

1. Blockchain enables digital provenance through:

• It’s transparency. Ledger is public and can be checked by anyone.

• It’s structure. All the records are permanently stored on the blockchain. Unable to erase anything.

2. Normal database doesn’t bring the same provenance because:

• Usually there is a centralized governance body that has to be trusted.

• Through the centralized structure of a normal database it can be more easily hacked or modified. For Bitcoin, you have to have 51% overtake of the network to hack it.

3. Digital provenance it’s a great benefit for many businesses:

• it provides transparency

• eliminates the trust

• easily verifiable

[yusufhashem]

Blockchain enables digital providence by allowing any user or member of the community to trace the origin of a transaction. This allows them to audit the transaction and verify the payment rather than trusting the users involved.
2. Blockchain can not be change, once a data point is added, it is permanent. A normal database can be subject to editing and therefore inefficcient for provenance.
3. It can allow for busniess to be audited digitally within minutes rather than being audited over a prolonged and expensive process.

[Florian]

1. It is a database where you can just add information but not delete it, so the given information in different steps of a process can be tracked completely.

2. Because the information can (theoretically) be changed all time, so the trust in the given information is normally pretty relative.

3. They can track instantly, continously and trustlessness different information.

[SAINTPATRICK]

1. blockchain allows you to keep track of items and their origins. Also all transaction are stored on the blockchain and is immutable. It also takes away the need for trust

2. regular databases are centralized which means they are the only node and are generally private.

3. It helps with real time audting

[Fiibei22]

1. Blockchain technology enables digital provenance through providing a secure, decentralized and tamper-evident record of transactions.
2. One basic difference between a normal database and provenance is that normal database is typically centralized. This means that it is controlled by a person or organization. As it is centralized, it can easily alter data without anyone else being aware.
3. Provenance offers advantages especially to industries where authenticity and traceability of goods are important. Benefits of provenance includes increased transparency, improved efficiency, enhanced security and increased competitiveness.

[decrypter]

How does blockchain enable digital provenance?

• Enables tacking of origin of events like financial transaction or a the origin of components in a suppy chain

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

• A database is not immutable, informatgion can be changed

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

• Trusless transactions
• Verifiable origins
• Easy auditing including real time auditing.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?
   Through the public decentralized ledger where everyone can verify information promoting transparency and accountability.
2. Why doesn’t a normal database bring the same provenance?
   Centralization. It leads to manipulation and lack of trust.
3. Why is digital provenance such a great benefit to many businesses?
   They can provide a real time auditing to the information contained in their product offerings

[Theo_Tzu]

1. Blockchain enables digital provenance by creating a decentralized, tamper-proof ledger of transactions. Each block in the chain contains a record of multiple transactions, and each block is linked to the previous one through the use of cryptography. This creates an immutable record of all transactions that can be easily tracked and audited, providing a clear chain of custody for digital assets.

2. A normal database does not bring the same level of provenance as a blockchain because it is typically centralized and controlled by a single entity. This means that there is a single point of failure, and it is possible for the database to be tampered with or manipulated without detection. In contrast, a blockchain is decentralized and distributed across multiple nodes, making it much more difficult to tamper with or alter the data.

3. Digital provenance is such a great benefit to many businesses because it provides a clear and immutable record of the origin and ownership of digital assets. This can be used to track the movement of goods through supply chains, verify the authenticity of luxury goods, and ensure compliance with regulations. Additionally, it can help to reduce fraud and improve the efficiency of business processes by providing real-time visibility into the movement of assets.
