Homework on Provenance - Questions

  1. Traceable and verifiable transactions on a blockchain are stored on the public ledger, providing trustlessness and provenance.
  2. There’s no way to verify that transactions on databases that aren’t decentralized haven’t been tampered with or double-spent.
  3. Because a business’ ledger can be audited easily without having to rely on trust. They and their customers can see whether or not the products’ quality is as advertised, reducing opacity.
  1. With a decentralized ledger you can’t remove information. This creates a trustless environment where the information can be tracked, verified and audited in real time.

  2. With a normal database you have to trust the keeper of that ledger. You have no way of knowing the data have not been altered and therefore can’t build efficient systems that brings provenance.

  3. Not having to trust anyone but instead verify on your own you can build systems for tracking supply chains, auditing and get transparency, automatically and in real time.

1} Blockchain has built in features that enable digital provenance. It allows for the tracing of desired information along with verification.

2] The designed format of a normal database does not possess such an ability to bring provenance.

3} It pulls everything together which allows accuracy and completeness. Also allows for realtime auditing if desired.

  1. How does blockchain enable digital provenance?
    Blockchain is a Public ledger, it is therefore verifiable by anyone and so you can prove the origin of a product and its movement through the supply chain as a result. Since a blockchain cannot be amended we know that the information is true.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database can be standalone, therefore it does not have the security of a blockchain with it’s network effect. This means it can be amended, deleted or even lost by individuals. Blockchain databases are immutable and backed up by numerous computers all storing the correct information, a database is no where near as robust.

  3. Why is digital provenance such a great benefit to many businesses?
    A company can track its supply line from origin to delivery, this ensures they get what they have paid for and no shortcuts have been taken or supplies tampered with. Counterfeit products can be irradiated with digital provenance. Real Time auditing is also a major benefit that can be gained, providing efficiency savings.

  1. Because is all transparent and anyone can see what is wrote in blockchain.

  2. For many reasons like is centralized and anyone can work on database,private database is not secure

  3. Easier way to show a data to customer,to control and save many options of data

  1. A blockchain is a public, decentralized ledger. Since every transaction is recorded [be it food ingredients, origin of clothing factories and their labor practices, supply chain…] on the blockchain, it allows for digital provenance. It is important to remember that the ledger is immutable.

  2. A normal database involves manual interaction and therefore, its accuracy is assumed based on the trust in the entities involved. It also depends on their objectivity, or lack thereof of the persons recording those transactions. Furthermore, different transactions can exist in different databases and pulling them all together can result in error and or manipulation of the date. In brief, the provenance is always suspect.

  3. A digital provenance allows access to all parties [unless its company specific, in which case sensitive details are encrypted away from public view]. By having access to data 24/7, it allows for continuous access to information and even allows real time auditing. Knowing that the system is trustless i.e. based on math and not human objectivity, provides confidence in the data being reviewed.

  1. Blockchain provides the enabling of digital provenance by showing a publicly distributed, decentralized ledger available to all enrolled participants. By having this decentralized cryptographic ledger we are able to view and track anythings ownership or location (but not limited to) in a digitized, trust-less way without centralized modification. On-chain verification.

  2. A normal database does not allow for this level of provenance due to the level of trust and centralization required of said database. Without blockchain enabled digital provenance, the current state of databases may operate manipulatively and opaquely… Instead of efficiently and transparently.

  3. The benefit of digital provenance is limitless. It allows businesses, consumers, and all levels of participants to track, audit, and verify efficiently and trust-lessly. It also enables for true transparency as an operator and user, ultimately empowering users and forcing participants to be open and transparent. Eliminating shadiness and negative motives, I personally believe this process of trust-less verification and transaction auditing on-chain will allow for us to evolve as humankind in a positive way!

1.Blockchain enables digital provenance by making things easier to track. Examples of this would be the ease of auditing financial transactions by big financial firms or the capability to track ingredients in your food. Provenance is all about being able to track things.

  1. A normal database doesn’t bring the same level of provenance because normal database are usually under control at one central point. Because of this centralization, information can be easily manipulated, edited or even deleted.

3.Digital provenance can be a great benefit to many businesses by providing real time auditing as needed, thanks to the blockchain’s capability to have a transaction and accounting layer. Relying on verifiable data and less on trust is another benefit to digital provenance.for businesses.

  1. How does blockchain enable digital provenance?
    A blockchain stores the entire transaction history ,and it is publicly available.

  2. Why doesn’t a normal database bring the same provenance?
    Normal database could be altered in any time by administrator or, in some cases, by hacker.

  3. Why is digital provenance such a great benefit to many businesses?
    You dont have to spend time and money on checking how honest your partners and suppliers are.

  1. It allows for the auditible accounting and transaction layers together rather than separately, in real time.
  2. A database can be altered or data can be lost. blockchain is immutable.
  3. businesses will be able to have a competitive edge by Proving the origin of their products through a verifiable network.

1 Blockchain is not control by any entity, governance, it is build as open public ledger that everyone can get access to it and be verify on this network encrypted, public and secure.
The data added on the Blockchain is totally decentralized and what is added on it cannot be removed by anyone .

2 The normal data base is not efficient whereas a decentralized public blockchain data is easily stored, it can’t be modify . In normal database you don’t really know all information and mostly need to trust an entity or a supplier,
if your are a company running a business it can be difficult to track and be sure about the transparency about your supplier and their products .
however in blockchain everything that you need to know is tracked from the beginning it is become trust-less .

3 You don’t have to trust third parties on their transparency, slogan ; don’t trust, verify

  1. Block chain enables digital provenance by being decentralised and cannot be changed, the block chain can only be added to and transactions are verified by each computer in the network, each transaction is transparent and verifiable

  2. Normal data bases are centralised and open to manipulation and control by organisations like bank, governments, easy to change.

  3. digital provenance will allow businesses to operate within a trustless society which will give them credibility and consumer trust because all transactions are verified mathematically. transparency and realtime auditing for example the traceability of ingredients in a product. the consumer will know for sure where each ingredient is sourced.

1)Blockchain enables digital provenance by making it decentralised - trust less unlike our banking system There is no centralised authority and nothing can be changed on the blockchain or removed.
2) Because the information is not transparent people have to trust the source where the information is coming from, therefor it can be manipulated.
3) Because there is verification it provides accurate tracability and real time auditing
