Homework on Provenance - Questions

[Attila]

1. How does blockchain enable Provenance?

Everything is written on the blockchain and can’t be erase. Every transaction is record at each step and make it easy to retrace back to the Realtime auditing aspect of blockchain.

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

Because a normal database is centralized and base on trust. Normal database are provate and it is up to the woner to chose what they want to make public or show. There is no guarantee of what they show is true.

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

It create a trustless environment as everyone can access at anytime the blockchain(Realtime auditing) for the provenance.

[CryptoRavioli]

1. How does blockchain enable digital provenance?
   Through having copies of the ledger distributed to multiple nodes offering permissionless access, transparency and immutability can be maintained in a trustless environment.

2. Why doesn’t a normal database bring the same provenance?
   The controlling entity of the database and infrastructure can limit access, change, modify or remove data. Outside entities will have a difficult time verifying the accuracy of the data and therefore must trust the controlling entity.

3. Why is digital provenance such a great benefit to many businesses?
   By streamlining access to supply chain, logistics, accounting information in a trustless way, all parties involved will benefit from knowing that inaccuracies will be rejected immediately, be they accidental or malicious.

1. Blockchain enables digital provenance because it is trustless, and easily verifiable by every computer running their own node.
2. A normal database doesn’t bring the same provenance because you have to trust that the central authority running the database is telling the truth about what is in the database.
3. Digital provenance is a great benefit to businesses because it can put the accounting and transaction layer of a business together, it can be audited in real time, and they can track where their supplies came from and have been.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?
   Since Blockchain is a “Digital Stone” in which all transactions that has ever occured can be verified and traced.
   The key part is that transaction and verification is done in tandem therefore there is no need for separate identity or function to verify.

2. Why doesn’t a normal database bring the same provenance?
   Because in normal database, transaction and verification cannot be done at the same time. process of transaction and verification is done seperately.

3. Why is digital provenance such a great benefit to many businesses?
   they can accurately track their supply chain. Main benefit is it is trustless and verifiable.

[eyetaliano]

1.) Digital provenance can only be enabled through a trustless, public ledger where all time-stamped transactions are recorded and never erased in a database that cannot be overwritten. In short, a provenance-based system allows the necessary transparency so that all nodes (members) of a network will always be able to “follow the money” (or products, services, metadata, NFTs, votes, etc).

2.) Normal Database doesn’t provide the same provenance because they are:

Centralized
Read, Write, Delete: unlike the Rune analogy, transactions can be modified by anyone who has access.
Are private, not public: the transactions of databases are privately controlled by a limited number of users with access. The security and integrity of the data is as weak or strong as the managers.
Subject to many security vulnerabilities including social engineering, hacking, human error, etc.

3.) Digital Provenance is a great benefit to businesses because through its design and process it builds and creates intrinsic trust in the system through:

trustless/permissionless contracts
transparent reporting of all transactions, verified and observable in “real time”
data is secured through encryption
the ledger is public and can be audited by any node (member) in the network

A combination of all these elements allow businesses to observe the chain of custody of all transactions with a public ledger. More transparency builds more trust in the network.

[Libardo_Bru]

1. by providing traceability of a transaction
2. Existing databases are not open to the public nor open to real time auditing, highly dependent of human error/integrity
3. greater transparency, savings in auditing fees, dodgy players will not be able to co-exist in the same environment.

[Suleno]

1. Blockchain enable provenance thanks to its infrastructure in which data can stored in it but it cannot be removed or modify. Basically since a piece of data is confirmed and written in the blockchain, everyone will be able to see it whenever he want, he just needs an internet connection and a computer.

2. A normal database can be altered by whomever control it, we can say that it is ‘centralized’. Instead the peculiarity of the blockchain is its decentralization, nobody is able to control and modify it.

3. Because it can turn in a save of money (e.g. in tracking transactions) or a perfect transparency among different actors of a supply chain or different industry.

[Briang]

How does blockchain enable digital provenance?

Blockchain is an unchangeable record, decentralized and open for public and private view.

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

It’s centralized and is curruptable

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

It allows for all of the use cases of traceability to be discovered and utilized.

How does block chain enable digital provenance?

• With a public ledger you can trace financial transactions in real time, real time auditing. It is easily accessible. You can achieve efficiency. Transaction contains all information and bridges transactions to accounting.
  Why doesn’t a normal database bring the same provenance?
• In a normal database you are able to edit and or delete transactions. In block chain database you are only able to add to the ledger and it is verified among several machines within the network as group consensus.
  Why is digital provenance such a great benefit to many businesses?
• It benefits businesses by achieving a trustless process by eliminating the reliance on 3rd party businesses for verification, accuracy and timing of information and or transactions. The information is stored on the public ledger that is easily accessed.

[Kyle_V]

1. How does block chain enable digital provenance?
   It creates a digital ledger where you can only make transactions that can be used in real time by anyone or by auditors to track supply and transactions in real time.
2. Why doesn’t a normal database bring the same provenance?
   Because it does not combine the transactional information together with the accounting information.
3. Why is digital provenance such a great benefit to many businesses?
   Real time auditing, trust-less verification, and transparency of accuracy creating efficiency and optimization.

[Presley]

1. By joining the accounting with transaction transparency to create a trustless, transparent, and more efficient system.
2. Normal databases are based on trust where the public cannot track or verify the origin of the product or service.
3. It provides transparency and efficiency in a world of skepticism and scams.

[runHikeClimb]

1. It keeps a record of the transactions/information you are saving, whether it is a financial or logistics/supply chain
2. Unlike normal database blockchain records transaction and does not overwrite it. It will just add more transactions later on the block and it will be hard to to take control of the block since you will have to convince majority of the nodes to validate your transaction.
3. Makes it more easy for users to see the information on open ledger, in the example mentioned accounting and auditing can be done quicker because you already have the transaction recorded.

[divingabc]

1. How does blockchain enable digital provenance?

Blockchain is a decentralized, tamper-proof ledger that records every transaction related to the product in question. The origin and destination of each transaction is permanently documented and considered as immutable, which translates to data authenticity, integrity, and validity.

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

A normal database is centralized, controlled by administrators, and based on trust. Databases lack provenance because data can be manipulated. Unlike a blockchain, a centralized systems failure can prevent database access. Unauthorized users, such as hackers, can compromise, manipulate, and steal data. Potential and realized threats to databases are common, which further compromises data validity.

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

Digital provenance helps business meet regulatory compliance, offer real-time tracking solutions, and provides transparency. Trust is no longer required because every detail can be verified on the blockchain.

[markonosuke]

1. Blockchain is an open system and everyone can verify what’s going on and where everything comes from.
2. Because not everyone can access it and verify it.
   3.Because it allows to keep tracking of everything and remove trust on other companies.

[Grdylineman]

1. Allows users to see all transactions in the database from anywhere
2. A normal database does not have the same provenance because a normal database can be changed/edited
3. Allows transactions to be transparent and permanent, more secure, provenance can provide peace of mind to users due to the fact that they can verify all info and know that no one can make changes.

[Pedrop8560]

1. This is done through its intrinsic properties like keeping records of all the info regarding each transaction from when it started to its actual status.

2. A normal database can be easily manipulated and there is also information that is processed independently in order to collect all the info about one transaction, Whereas with block chain, you can have this info in just one process.

3. It brings the possibility of having all your data and transactions history in one place and in real time. This can reduce operational cost, it can give market advantages due to the transparency that block chain can give to customers when they can track the history of their items.

[manuel.simulescu]

1. • All transactions are stored, no information is deleted or modified.

• All info is open (public)

2. In a normal database information can be deletes or modified

3. Removes the need for trust, all transactions are public, auditable.

[CryptoCurlz]

1. How does blockchain enable digital provenance?
   Track and audit transactions in real time.

2. Why doesn’t a normal database bring the same provenance?
   Traditional trust is required - verified by third party auditors, normal databases CAN be modified, manipulated and controlled.

3. Why is digital provenance such a great benefit to many businesses?
   Transparent, Immutable, Secure, Cost Effective, Trust not required - you can verify

[Tesh]

1. How does blockchain enable digital provenance?
   It is a digital ledger which anyone can verify in order to serve a purpose. Record keeping is valuable in many contexts, and a blockchain allows a robust form of record keeping.

2. Why doesn’t a normal database bring the same provenance?
   A normal database can be changed, a blockchains records cannot be chained. A normal database is also centralized.

3. Why is digital provenance such a great benefit to many businesses?
   It enables outside parties to verify information about the business, such as for supply chain , or auditing.
