Homework on Provenance - Questions

Blockchain and Bitcoin 101
#3431

  1. Blockchain provides provenance through the immutable and transparent ledger. Everything and anything can be verified through the blockchain.

  2. A normal database is not public or immutable. It is reliant on trust that all actors are inputting the correct data, and that data is not manipulated.

3)Provenance can be useful in any industry where a chain of custody would be beneficial. In the global economy, many industries specialize and are reliant on their partners to finish a product. Having the ability to track all components allows for greater efficiency, and a trustless way of doing business.

  1. How does blockchain enable digital provenance?
    With transparency and trustlessness. All with verification of the transaction. Real time auditing.

  2. Why doesn’t a normal database bring the same provenance?
    Cause there is no real time auditing. There is no one else to verify the information except the centralized party.

  3. Why is digital provenance such a great benefit to many businesses?
    Capability of tracing things and removing trust from so many fields. We dont need to trust that the supplier are telling the truth. we can just verify it.

1.How does blockchain enable digital provenance?
All the information are transparent and cannot be edited or removed also every transaction data can be traced back

2. Why doesn’t a normal database bring the same provenance?
A normal database is centralized, therefore anyone who has access to it can change the information or data can be lost due to errors and can be difficult to recover. Requires trust and transparency.

3. Why is digital provenance such a great benefit to many businesses?
It is beneficial to businesses because materials can be traced for authenticity and origins. All products are tracked in realm time making it more time efficient.

  1. How does blockchain enable digital provenance?
    Blockchain combines the transaction layer with the accounting layer. In this way, the history of the data in the transaction is automatically recorded.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database depends on a centralized authority, which is in full control of the stored data. Blockchain on the other hand is trustless.

  3. Why is digital provenance such a great benefit to many businesses?
    It increases efficiency and transparency by removing the need for trusted intermediaries.

  1. By “engraving” information into the immutable blockchain ledger, provenance prohibits alterations to this digital “stone”.
  2. Normal centralized databases provide one strike point for hackers along with the ever present concern that your trust in the centralized authority may be broken. The authority has the ability to manipulate the database.
  3. Lower costs of accounting, avoid costs of audits as they occur on-going in real time, avoids possibility of hacking or internal account manipulation.

  1. Blockchain as a public ledger with immutable property and no authority to control it including government agencies provide digital provenance. Each step involved in a process can be added to blockchain and public can conduct real time audit to track the status and condition of the current state.

  2. Entries on a normal database can be edited or removed by the authority administering the database. Normal databases cannot be called as a transparent immutable ledger.

  3. Digital provenance can be great in a way that the buisness can exactly know its current state of finance, how much cash is flown out of the company and how much cash the buisness currently hold. In terms of tracking raw materials and other external services for the business, with digital provenance, the business can now track from where the raw materials are coming and what are the raw materials used by external company to render external services for the business. It can help in maintaining the quality of product and can monitor whether the business is unknowlingly involved in any of the illegal activities like child working or environment exploitation, etc.

1.it provides a ledger kept buy multiple entities that cannot remove information, and verifies all inputs with other entities on the blockchain.
2. There is too much trust in a normal database
3. It removes trust and allows companies to verify many things like where a product has been and if it were made in a factory that uses child labor or not.

  1. Through immutability of blockchain we can trace all the transactions, information without the need of trust.
  2. We have to trust the person working on the database is imputing correct data. Naturally it could be tampered with - cooking books etc. In blockchain it is impossible.
  3. Brings transparency, rewards good practices.

Block chain enables digital provenance by allowing traceable, verifiable and unchangeable ownership on a public ledger through a network of computers. It is immutable because nothing can be removed only added and is decentralized thereby making it trustless.

A normal database does not bring the same provenance because normal databases are centralized and vulnerable to tampering with or loss of data. It doesn’t have the same trackability as a block chain enable digital provenance due to the decentralization of block chain.

Digital provenance is such a great benefit to many businesses because it creates peace of mind knowing there is a traceable public ledger with easy access, and the ability to tract physical products origin, ingredients, locations, quality of products anytime.

1.Blockchain is a database which you can not change after entering it. This is how trust in this system is created. Without a decentralized authority.
2.A normal database can be changed afterwards and is also mostly central so it is easy to attack. With the blockchain there are many nodes that control each other and control new entries. It is not so easy to hack all nodes and change the data.
3.It is cheaper and faster than the conventional methods. You can gain trust more quickly and you can control the steps more easily.

  1. How does blockchain enable digital provenance?
    Because every transaction and the log from that transaction is open to the public or able to encrypt it so only the right people can access the log.

  2. Why doesn’t a normal database bring the same provenance?
    Because the database is vulnerable to hackers and you are able to edit or delete the database.
    It is also a locked system that is not easily accessible for anybody outside the company. We have to have trust in those company’s to believe that we are receiving the right products/information.

  3. Why is digital provenance such a great benefit to many businesses?
    The company’s can provide much more information, trust and verification’s to their clients.

  1. How does blockchain enable digital provenance?
    By creating a decentralized ledger, any user can see everything, and the data is verifiable

  2. Why doesn’t a normal database bring the same provenance?
    Because of the fact it would be centralized, a normal database can be tweaked, therefore it is not as reliable as a blockchain based database

  3. Why is digital provenance such a great benefit to many businesses?
    It provides customer assurance and ensures a high quality product

  1. Blockchain is a data structure that can only be added to, so it enables digital provenance because every change made in the digital custody of an item can be traced and verified all the way to its origin.

  2. Normal databases can be added to or subtracted from by anyone with access and are subject to human error, the digital item or representation cannot be traced to the origin so there is no verification of provenance.

  3. Digital provenance is a benefit to businesses because it allows for trustlessness between all transaction participants from top to bottom. Allowing businesses to fully trust merchants and suppliers and allowing their customers to fully trust the business and make more informed purchase decisions. This will allow businesses to build stronger customer bases, easily choose trustworthy suppliers, and provide safer products.

  1. enable digital provenance with veryfying databse from all blocks and users who has full databse on their mining machine or computer.
  2. Because in normal databse you can have double spending problems witch is disable in blockchain by creating blocks.
  3. For example you can track easily taxes, there are not mistakes with double spending problems, is public open for everyone. Blockchain

  1. By only adding data to the blockchain as entries/transactions, and not taking any away, there is always a record of all the data added to the chain. And since it is decentralized, no one can take any of the data away.

  2. Entries/transactions can be taken away from the database from the central hub. So the government/group/organization running the database can alter its contents.

  3. You can always check the validity of entries/transaction by referring back to the code and doing real-time audits. It makes it trustless.

  1. How does blockchain enable digital provenance?
    Allows the real time tracking and auditing of transactions that can’t be altered by a centralized entity or third party and can be viewed by anyone.

  2. Why doesn’t a normal database bring the same provenance?
    The accounting and transaction layers are separate in a normal database, which can be susceptible to inaccuracies or changes without public knowledge by their centralized entities that control them.

  3. Why is digital provenance such a great benefit to many businesses?
    You would be able to track information more accurately, such as the example talked about in the video regarding the ingredients in the food being shipped. Digital provenance will allow to check the state of a product in a supply chain and check details such as its ingredients, allowing verification of quality at any point by anyone in a trustless way.

  1. Blockchain enables digital provenance by using a public ledger system where the system verifies every transaction in real time by using computers built for blockchain.

  2. A normal database does not have the same infrastructure to achieve this feat because it cant record the transaction as well as purchase while also verifying your funds all in one system.

3.digital provenance is a great benefit because instead of needing to put your trust in the validity of your transaction everything is automatically verified for you.

-Blockchain enables digital provenance by acting as a permanent ledger which transactions can only be written.

-A normal database does not have the same provenance because transactions are settled in a centralized manor, making transactions mutable.

-Digital provenance would benefit businesses greatly via ease of audits, inventories, and material tracking.

  1. Blockchain creates a timeline of linked data across a consensus network. In this public ledger, information is recorded when new blocks of data are generated and this new data is verified by the network database and linked to it’s predecessors. An attempt to distort pass records would be invalidated against the consensus, creating a trustless, verifiable, permissionless recording system.

  2. Normal databases are centrally controlled meaning personal gain or collusion can influence records of data as this data may be altered or lost without a consensus to stop it. If a natural disaster, or man made one, occurs even if the host of the normal database is honest, they are still subject to data destruction where as a consensus network is not geographically isolated.

  3. Digital provenance eliminates the need for businesses to entrust that promises or agreements between others will be fulfilled, as the data involved with logistics and production are public. The speed at which auditing can occur, at real time if desired, prevents the slow down of performing manual inventory checks, or record screenings, reducing human error and man hours involved.
