Homework on Provenance - Questions

  1. The fundamental purpose and idea of blockchain technology is the creation of records of transactions (or histories of ownership) the integrity of which is guaranteed by a network of nodes (miners in the case of crypto-currencies). In other words, blockchain technology is relevant not only to currency transactions but to transactions in general and thus enables digital provenance (because provenance, by definition, is a documented and authenticated history of ownership).
  2. A normal data base does not provide the mathematics-based security of a blockchain network. It relies for its integrity on the honesty of the indivdual human beings or organizations that create and maintain it and is in this sense not trustless. Put differently, a normal database needs to be audited whereas a blockchain record of transactions is audited, as it were, continuously by the nodes in the blockchain network.
  3. It is such a great benefit because it increases business efficiency by eliminating the need for audits or independent verifications. The history of the components of a product, for instance, can be traced almost instantaneously and perfectly reliably, and without a need for a cumbersome third-party verification of its authenticity (assuming, I suppose, that the network has not been taken over by a dishonest conspiring majority of nodes).

  1. How does blockchain enable digital provenance? By creating a permanent, unobstructed record of every transaction. Every transaction movement is permanently communicated on the blockchain.
  2. Why doesn’t a normal database bring the same provenance?
    A normal database operates from a central power structure that can be manipulate the database. The blockchain provides a permanent record that cannot be manipulated.
  3. Why is digital provenance such a great benefit to many businesses?
    It allows for complete trust, understanding and realtime auditing of any transaction record or supply chain.

1 - able to track all the tranactions on real time
2 - because with the blockchain , you can add things but can not remove, all transactions recorded, you can track it anytime you want it.
3 - will help business to track any thing include on their supply as ingredients , any stats of their products get in before they receive its, this bring truthless between between business and supplyers,

By tracking both Accounting and transactions in real-time through Blockchain Network.

The normal database can be manipulated and trust is a variable, where the processes are opaque. They need to be audited.

It not only saves time and money by realtime auditing, but it also helps to eliminate the need to trust rather verify.

  1. How does blockchain enable digital provenance?

The blockchain decentraly documents the history of ownership immutably. Once an object is on chain its history cannot be altered and is viewable by the public. This level of documentation allows for easy authentication of ownership as verified by possession of the cryptographic keys associated with the asset in question.

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

A Normal database does not have a permanent immutable chain of custody nor the cryptographic keys to verify ownership.

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

For all the reasons mentioned in answers 1 and 2 though the bottom line is Digital provenance removed the need to trust the business or the need to trust the individual and replaced it with trust in the technology.

  1. How does blockchain enable digital provenance? Blockchain enables digital provenance through allowing every transaction to be tracked in real time rather than waiting for an adit through be the company or a third party. It allows for easy verification/validation to occur by the customer.
  2. Why doesn’t a normal database bring the same provenance? With blockchain records cannot be erased and these records are public allowing anyone to check anything at anytime.
  3. Why is digital provenance such a great benefit to many businesses? Complete transparency and real time status on all transactions. Nothing is hidden or can be changed so the quality of products as well as the materials or ingredients of the products can be verified at any time.

Very succinct :clap:t5::clap:t5::clap:t5:

  1. It deletes trust and add verification. Since it’s stored in a public ledger, it can all be traced and tracked in real-time.

  2. A normal database is depending on trust, like a person / organization / company that have verify the information.

  3. Since every transaction on currency or information is traceable, it adds trust from the consumers to the companies. It’s very effective and secure.

  1. by being on public ledgers that are immutable, transactions can be changed or edited. Can be cross-referenced with all other ledgers. All transactions are verified and trust less
  2. normally transactions can be altered or even erased. Also you have to ‘trust’ your source to some extent
  3. transparency and no need to have to trust the source as it is already verified by all other ledgers
  1. I meant CANNOT (not can be changed)
  • 1 - Blockchain enables digital provenance through allowing every single transaction to be traced back to its origin. Blockchain saves data into it’s own ledger (database) where every transaction places permanently and can not be removed or changed.

  • 2 - Regular or traditional database always has someone who controls data therefore database can be changed, removed or manipulated. This is complete opposite what blockchain provenance does.

  • 3 - I think o lot of businesses out there need to protect their clients data and privacy. Blockchain offers great opportunities for any type of business that deals with clients data.

  1. How does blockchain enable digital provenance?
    Blockchain as a technology, is representing a game changer innovation that can find infinite applications in every sector by allowing direct verification and trackability of processes. The main point of the blockchain is its immutability and impossibility of records tampering, due to the fact that the information of all steps of the supply chain, transactions and records is stored and distributed on a network of computers which share an independent copy of the ledger, which is in fact public and open to examination by everyone. It also offers encryption if required so that information can be verified in detail. The decentralization guarantees the truth of the information recorded and eliminates the need of trust between counterparties.
    It also enable real time auditing, if needed, improving and cutting the middleman in data verification.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database must be created, maintainted and audited. In addition to that, it is still -by definition- subject to a degree of risk of tampering as it could be accessed and edited by rogue operators. It also does not eliminate the need of trust, which is still the basis for business relationship or process verification.

  3. Why is digital provenance such a great benefit to many businesses?
    It cuts costs, timing, improves trackability and is public. It is efficient and transparent in all aspects and allows a total guarantee that the information is true and verified.

  1. By providing track, trace and auditing of every transaction in real time, combining accounting and transaction layers, no need for traditional auditing services.

  2. Because it is a centralised system built on trust, data can be manipulated or lost.

  3. It is decentralised, trust-less and immutable…

I would say that blockchain enables provenance in at least the following areas:

Accounting,
Reputation,
Blame,
and
Efficiency.

Because a signature would be needed at every stage of any verification line, all that could be said is that a certain signature was associated with a certain action or set of actions. Such as the action of the creation of the signature, what it is associated with (i.e. a person, place, or thing, etc), and what tracked actions are made based an those associations.

So as far as accounting is concerned, transactions and records are easily tracked and associated with the signatures of all involved, removing to a very large degree the need for trust.

When it comes to a supply chain, say a grocery store, signatures at every stage of a produce item, can be used to associate blame if the item has an issue, such as contamination. This allows for a quick but also limited recall of all affected items, and the ability to find what went wrong, and efficiently to fix the problem. The same is true of business’ that add value through production, such as factories. The ability to recall a much smaller number of items, and also to fix the problem in short order, benefits the business both in time, money, and reputation.

Reputation has another aspect as well. The brand of the company is affected by it’s reputation. For instance if every stage of production is tracked via signatures, then if it is discovered that say, child labor was used, then the issue can be stopped immediately.

Because it is a signature that is tracked, and not a person, there is still some trust involved. Even if a part of the private key of a worker contained a hash of a bio-metric that they possessed, you would still have to trust the reputation of the person’s (signature) that gave them the private key in the first place. Because blockchains track signatures and not people, there is some trust involved in supply chain issues, so blame and reputation are closely intertwined.

Protecting brands means that signatures are being sold. For instance a clothing business that wants to defeat counterfeits of its products from replacing its own sales, can have a signature for each item produced made available on a blockchain. The profit motive works well in this scenario, because it would not be profitable to steal a box of clothing items, take the QR signatures off of each item in the box, and then put it on counterfeits. However it would still be profitable to take the signatures of from one employee of a business, and then using that same signature for a different one, that was not legal for a business to employ. So the case where a business wants to eliminate competition from illegal counterfeits works better, than the case where a consumer wishes to protect themselves from contributing to child labor, which will possibly only be found out after the fact, but still allow for better blame using a blockchain.

  1. At every stage of the delivery chain, relevant data is gathered and recorded on the (immutable) blockchain. Recording all this information on the blockchain enables anybody to verify this information (assuming the information was collected truthfully before it entered the blockchain?)
  2. A normal database can register data like a blockchain, but as it is centralized and controlled by a third party it can also be changed by that same entity, so we need to trust that entity for it not to manipulate the information.
  3. It makes the system trustless, meaning that all companies along the delivery chain can verify the information on the blockchain and trust it (again, if the initially registered information is true - garbage in -> garbage out). Furthermore, all information is available on the blockchain and businesses don’t depend on information relayed via inefficient and slow data transfer processes by companies earlier in the delivery chain, the whole process becomes transparent to all companies (and to the consumer).

1. Blockchain as a technology is game changer. It takes away trust and adds verification, every transaction can be tracked in real time. Once added on blockchain it is impossible to manipulate or alter in any other way. It becomes public information for anyone with internet connection.
2. Normal databases usually are owned by someone, so its based on: Me trusting the provider(company, person…) and it is permission based.
3. It saves a lot of time, cuts the middleman. There is no need for trust, all proceses can be verified.

1 A tamper proof ledger with transparency and traceability from all points
2 Data can be manipulated stolen or lost
3 The customer no loner needs to trust you they can verify your product supply chain and quality control in real time

  1. Blockchain provides provenance by having an immutable public ledger providing information for all the transactions that have taken place since the first one.

  2. A normal database will have a central entity that can potentially manipulate the data and information. The information may not be public as well. These two factors make it so that past information can be changed without anyone other than the central entity being aware.

  3. It can provide the transparency and accountability based on the certainty of maths rather than the uncertainty of humans. Thus creating the ever greater efficiencies in business and beyond and well as providing other benefits.

  1. Blockchain enables digital provenance because it allows for transparency and verifiability in the supply chain. Enough visibility is provided for the end consumer to remove the need for trust. Since blockchain is also immutable and distributed, it is much harder to tamper with the data unlike traditional solutions in use today.

  2. A normal database doesn’t provide the same benefits as a blockchain because such databases are usually under centralized control, the same company that’s providing you the products that you are purchasing may control the database. The company can fabricate or omit data at will whereas they are unable to do so with an immutable distributed ledger.

  3. Digital provenance allows for businesses to remove the need for trust and give them opportunity to provide higher quality products to their clientele. Whereas in the past, a substantial number of companies did not have a good idea as to the makeup of the supplies they were receiving from suppliers, digital provenance allows businesses to easily and reliably determine the source of the goods they’ve received.

  1. Blockchain enable digital provenance by using an desentraliset netvork o ledgers, that holdt all information as if written i stone, and it is not possible to remove info. Therefor you can track all trails of what you are seaching.

  2. A normal database is closed for public, and not transparent for others to see. Therefor we have to trust the information we are given, insted of verifying it.

  3. It is a great benefit because it rewards a honest and clean way of building your product or survices, and without having to depend on other governments, banks or firms for permission, you are free to be creative and try your best, and the world is an open playground for everyone who puts in the effort.
