omework on Provenance - Questions

1. How does blockchain enable digital provenance? It allows us to trace financial transactions in real time.
2. Why doesn’t a normal database bring the same provenance? A normal database can’t do this in real time for some reason.
3. Why is digital provenance such a great benefit to many businesses? It increases efficiency by putting the accounting layer with the transactional layer. It allows us to achieve trustlessness and increase efficiency at the same time!

So if I understand correctly for the part about humans,they can still corupt the info that they give regarding their products in a supply chain,also if miners collude for a 51% attack, they can also damage the operation/chain(fairly unlikely but possible) but blockchain takes the way data basis work to a next level by almost adding automated transparency?

Question 1. How does blockchain enable digital provenance?

Blockchain technology, also know as distributed ledger technology, can be used to record the origin and history of any digital asset. Blockchain achieves this through utilizing its decentralized network of cryptographically signed ledger entries, where digital assets are distributed to every node on the network rather than copied or transferred. This decentralized distribution chain gives everyone access to the digital asset at the same time, and all modifications to the asset are recorded in real-time on the network nodes and validated by miners, making fraudulent changes to the asset impossible.

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

If a traditional centralized database server fails, or an actual centralized physical database is damaged or destroyed, unless proper backup measures, including off-site hard copy of the database are in place, the entire system is affected. This can also be the case if fraudulent entries are made, or entries removed for fraudulent purposes. There will likely be no record of these changes to the ledger, and as such, leave it open to attack from bad actors. The blockchain does not, in this regard, exhibit these failures, as, Being decentralized, there is no one single point of failure, with all records being broadcast to every node on the network. It is this permanent storage of transactions and assets, stored on multiple nodes, and validated by miners, that cannot be deleted, changed or modified, that makes the data immutable, and resistant to tampering. This makes blockchain technology far superior to traditional data storage, with full public data transparency , and Protection against fraudulent data entries or removal.

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

Trust in business is crucial for economic growth, but advances in technology bring with it problems of authenticity. As hackers become more and more adept at counterfeiting digital products, digital provenance provides a platform for trust less supply chain data, academic research, User authentication and digital goods, blockchain technology provides business with the tools to confidently review the legitimacy or provenance of a digital asset or product, building trust business to business, as well as building a confident consumer base.

1. How does blockchain enable digital provenance?
   It does so by embedding a digital signature that can be used to validate authenticity.

2. Why doesn’t a normal database bring the same provenance?
   Databases are not immutable and can be changed by anyone given access.

3. Why is digital provenance such a great benefit to many businesses?
   Because it removes any reliance on 3rd parties audits and helps mitigates instances of fraud and corruption.

[knersus]

1.It allows you to track a transaction right from the source of the product in a transparent and decentralized way that is also censorship resistant.

2.There is a central authority/power(centralized) that controls it and it can be manipulated because it is not open and transparent.Legacy databases also has a lot of auditing and on the blockchain this can happen in real time in a transparent way.The blockchain is also more censorship resistant.

3.It creates an open and transparent system for the whole chain from origin to customer.

[mkhuang]

1. How does blockchain enable digital provenance?
   All recorded transaction on the blockchain cannot be erased or changed, immutable, thus making it easy to track every single transaction to date thus enabling digital provenance
2. Why doesn’t a normal database bring the same provenance?
   Normal database can be changed, removed or even lost. Therefore it does not provide the same provenance as blockchain can.
3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance is such a benefit to many business because it is easier, safer, more secure and transparent

• How does blockchain enable digital provenance?

By stablishing a network that process data by automation. The rules of that process are public and will never be disobeyed without the trace. Since the rules, and the public aspect of it, are the authority, that are no need of a central authority embodied on a bank or a politic institution.

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

Because the inevitable falibility of the humankind prevent us from being absolutely righteous about decisions wich implicate or own benefit. That said, all the monetary authority of the fiduciearies coins relies on the public trust on tecnical and moral habilities of the politic and market authorities.

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

By its capacity of keep a transparent and reliable trace of the informations about the process of production, logistics and storing of its products.

[ryan_n]

1. How does blockchain enable digital provenance?
   All transactions and activity of the digital asset are recorded in the blockchain maintained in a decentralized fashion, making fraudulent changes impossible, thus providing the true origin and history of the digital asset.

2. Why doesn’t a normal database bring the same provenance?
   Because they are run by a centralized manner so there is always risk the information in the database be altered or damaged, unless you can really trust the person maintaining that database.

3. Why is digital provenance such a great benefit to many businesses?
   Because it does not need to trust someone to get the accurate information, it makes accounting and audit very easy.

[Emmi]

1. How does blockchain enable digital provenance?

• by embedding a digital signature(tokenizing) that demonstrates the authenticity/provenance of a specific item on to the blockchain.

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

• Unlike Blockchain database which can never be modified or corrected in any way as it is a public ledger that not one person controls, conventional database can be manipulated/modified by the individual/enterprise that controls/owns that database thus making it vulnerable to foul play.

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

• transparency, trustleness, lower costs, less time spent on bureaucratic paperwork, more time spent on improving the business/costumer experience, to name a few of the ones I find to be of most importance.

[rapheldior]

1- Trough code it builds a decentralized database, in which no trust is needed beause everybody can verify every transaction.

2- Because a normal database is based around trust in a authority. a individual is not able to verify the correctness of a transaction, therefore the authority might missuse it for there benefit.

3- Individuals are finally able to verify if what is being told to them is actually true, no more false promises of businesses. therefore businesses that are not meeting the customers needs will disapear from the market. which makes in the end a much fairer market and therefore world.

[mohamed_navvaf]

1. How does blockchain enable digital provenance?
   A. Blockchain enable the data to be stored on decentralized public ledger in real time which is accessible by everyone.
2. Why doesn’t a normal database bring the same provenance?
   A. The normal databases are centralized and is more prone to single point of failure or
3. Why is digital provenance such a great benefit to many businesses?
   A. its efficient and is not based on trust is verified.

[UFAME]

1. By providing the ability to track via decentralized real-time auditing
2. Because it is centralized, relying on people vs unchangeable math
3. It provides transparency to customers for assurance through verification

[Ozarkshrub]

1. How does blockchain enable digital provenance?
   a. Immutability of blockchain creates an environment where everything is available to be seen, no question as to where it came from.
2. Why doesn’t a normal database bring the same provenance?
   b. Normal databases are not only changeable, but are generally held at one central location not available to be viewed by the public.
3. Why is digital provenance such a great benefit to many businesses?
   c. It provides a way to show that the company truly embraces what they claim to whether being green with their energy, non-GMO, or 100% organic.

[baads]

1. How does blockchain enable digital provenance?
   Blockchain enables digital provenance by being a database/digital stone that adds information about transactions that get verified by network computers. Information only gets added to the database, it doesnt get removed. This way the blockchain always keeps track of all transactions.

2. Why doesn’t a normal database bring the same provenance?
   Normal databases are centralized. Information can be added and also removed. So those in charge can remove information if they want to, and manipulate so the provenance doesnt show the right tracking of transactions. There is also a higher probability that the database stored in one place can easier get hacked, and then the information can be changed affecting the provenance.

3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance is a great benefit to many businesses because it assures a bulletproof, easy to track system for all transactions. They dont need to trust others, they can verify using by using systemathic math. This way is alot more efficient for businesses, than to keep all their receipts somere. Or have to have transactions verified by banks, or other people.

[SSXSF]

1. How does blockchain enable digital provenance?

With decentralization making everything trust-less and transparent no one person, government, or entity has sole control over the blockchain network in question

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

It’s not decentralized so it can be hacked, the books could be cooked and the normal databases don’t offer any REAL level of transparency

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

It would allow for 100% verification and a stronger consumer business relationship to be built

Homework on Provenance - Answers
1. Blockchain enables digital provenance by providing an immutable record of all transactions enacted by all participants within the network that is publicly verifiable.
2. A normal database allows records to be retrospectively edited and deleted, whereas every record of a transaction on a blockchain is immutable and can never be changed once it is written to a block on the chain.
3. Digital provenance is important to business because
a. No need for trust: It allows businesses to interact with other enterprises in a trustless environment since they can verify referenced transactions, authorisations, licences, supply chain distribution pathways, etc on the chain.
b. Everything can verified by anyone: It can eliminate barriers and bottlenecks in the supply chain, in negotiating deals, and sales e.g. if the required business’ claims/credentials/licences are on the blockchain, they can be verified by customers and prospective business partners alike. This would make it easy for participating industry partners to join and interact in the ecosystem, and for customers to trust they can verify every transaction they desire.
c. Customers can buy verified: Allowing customers to verify the businesses claims through such a publicly available secure network builds trust with the company and its products and services. Ultimately this will increase transactions, and hence business revenue, through this digital technology.
d. Posterity: The existence of the business will last as long as the network where their transactions are, remains in existence.

1. Blockchain enables digital provenance by creating an open public and permanent ledger of
   all data entries.
2. Data in a normal data base does not bring the same provenance because of two reasons.
   First, many data bases are not ‘open’ in nature. Second, data in a blockchain is permanent
   and cannot be removed, while this is not the case in a regular data base.
3. For businesses, digital provenance allows businesses to prove authenticity of prodects
   they sell.

[Aman_Hassan]

1. The Blockchain decentralized and it allows the tracking of a transaction. Every transaction is recorded on the blockchain and it cannot be removed.

2. Normal database is an old and clunky system, which has too many moving parts that can go wrong. The system is based on a lot of TRUST from the providers of the database which is centralized, can be manipulated, and may not be as authentic as its claim.

3.Because it brings real trust and customer satisfaction. The verification process via the blockchain has a more streamlined and efficient verification process for different materials and ingredient and the company that is claiming to use those materials have a better chance of complete transparency in their business practices.

[SyM]

1. Blockchains enable digital provenance thanks to three key factors: real time tracking of transactions, data immutability, and decentralisation. This creates an entirely transparent, traceable and trustless environment.

2. Normal databases do not provide data immutability, and are also centralised. They therefore still rely on trust to a large degree. Don’t trust - verify

3. Digital provenance is beneficial because it creates a fully traceable, immutable, and transparent network which can track everything from financial resources to products and supplies in real time. This enables businesses to keep a close eye on in-house and third party products, resources, supply chains, transactions, and so on. This trustless environment can also translate into increased efficiency and ultimately, cost saving.

[Fengzi]

1.Blockchain enables digital provenance by making it trustless and transparent. All data is recorded on the ledger so anyone can view what is going on. Blockchain allows for real time auditing, the days of lengthy audits can be a thing of the past because the audit on the blockchain can be compiled second by second of the transactions.
2. A normal database fails because the data can be removed. It is opaque rather than transparent.

3. Digital provenance is such a benefit because honest companies can demonstrate true earnings, it would be impossible to cook the books. It will also make auditing insanely easy. Digital provenance can combine accounting and transactions.
