Homework on Provenance - Questions

Blockchain and Bitcoin 101
#6608
  1. Blockchain enables digital provenance because entries can only be added to the database, not removed, therefor there is a permenant record.
  2. A normal database does not have provenance because entries could be changed by the database owner. You have to ‘trust’ the company maintaning the database vs the ‘trustless’ attribute of the blockchain.
  3. Digital provenance is a great benefit to many businesses because they do not have to rely on contracting a company to audit at a point in time - instead access records or transactions is openly available in real time. It can also improve supply chain tranparancy.

  1. It enables provenance because it’s an open ledger, with every transaction ever made, available to view by all

  2. Because it has verified every single transaction that has taken place in it’s existence, and it carries accounting and transactional layers together in one

  3. Because it removes the need for trust, and replaces it with verification, which allows businesses to rely more on the information their getting, and brings consumers one step closer to the truth and reliability of the purchased product

1.How does blockchain enable digital provenance?
Transactions are recorded and unchangeable. They are being traceable all the time.

2.Why doesn’t a normal database bring the same provenance?
A normal database can be changed without leaving any trace.

3.Why is digital provenance such a great benefit to many businesses?
Businesses can run on verified data instead of trust.

  1. How does blockchain enable digital provenance?
    Provenance simply means being able to track origin of things/events/transactions - auditing. With the help of the blockchain technology which is a public ledger, digital provenance can be don without having to rely on central bodies because all processes will be automatically recorded on the blockchain - it makes the process trustless.

  2. Why doesn’t a normal database bring the same provenance?
    because a normal database doesn’t keep a detailed record of all transactions and also is not easily accessible to everyone for verification.

  3. Why is digital provenance such a great benefit to many businesses?
    It makes the business trustless and verifiable.

  1. Because it is a public ledger that does not allow for information to be easily erased and every transaction becomes a permanent record.

  2. Normal databases do not have the ability to become a public ledger that allows for everyone with access to the ledger to become in a way an administrator/moderator.

  3. Because it allows for real time auditing or tracking of transactions.

        Enabing full transaction traceability 
        By connecting all the transactions from each other, and enabling consensus between all of them.        

    Why doesn’t a normal database bring the same provenance? 
        Becasuse is one single instance, able to be changed in a transaction basis, centralizaed and managed by the sysadmin!         

    Why is digital provenance such a great benefit to many businesses? 
        Because enables differente business models to take place, mainly distributed ones. 
        Because avoids traditional auditing needs, in a trustless platform by simply verify the transactions that can finger print the main operations. (example)

  1. By storing digital information/transactions in an immutable database. It’s trustless.
  2. Information/transactions can be altered.
  3. Auditing can occur in real time.

  1. The blockchain enables digital provenance by being able to trace financial transactions in real time, providing real time auditing in seconds and bringing more financial processes efficiently

  2. A normal database does not bring the same provenance because both accounting and transactions are separate layers, where blockchain combines both

  3. Digital provenance is such a great benefit to many businesses because it provides a way for the business to build trust with the consumers, I.E Food, if we as consumers can view where our food is coming from and see all the ingredients it provides a trust in the company, it also provides a visible way for businesses to trace each step

It enables digital provenance because information can only be added, not removed. Also, there is only one version of the blockchain – there are no altered copies floating around.

In a normal database, you can remove data.

It removes the trust factor: businesses no longer have to take their suppliers’ word. Thanks to a blockchain, businesses can verify the provenance of the materials or ingredients they buy.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?

Blockchain is a distributed database where the remove function is taken out of the equations. You can add but not erase. Thanks to that, you can verify anything that is written on it from its origin.
It is resilient because the network needs to accept the transaction, not only one actor. This means that I basically cannot corrupt the records. Even if I collude with another actor, or two, or three, the rest of the network will reject my transaction. Thanks to that, I can trust as a third party that whatever is written is indeed true.
Finally, the technology allows for anyone to audit in real time what is written and go as far back as needed, to track to the source.

So in summary, because of its trustlessness, auditability and immutability.

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

A normal database is accessed by only one actor (to simplify) that can do whatever it wants to it. Add, remove, replace or update. This means that if my finances are not great, I can change my records, when you read it, you can only see what I am giving you : you have to trust me, that I am competent and honest, and that everyone else before me, was competent and honest. Countless times we have seen that this is not possible (do you remember the Findus scandale?).

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

Many (all?) industries depend on inputs from other organizations further up in the value chain. Food was used but mining comes to mind too. I heard many times that if you have jewelry, no one can assure you with 100% certainty that you don’t have blood on your hands. Many miners do not respect work laws, destroying the environment and abusing workers. Traceability is paramount with a lot of businesses and with provenance, enabled by blockchain we can go all the way up or down the chain as needed.

  1. Every transaction is recorded, validated and distributed across the blockchain and its immposible to reversed. This characteristic of the blockchain makes the ledger immutable wich creates opportunities for real time audit and tracebility of the transactions.
  2. The centrilised nature of the normal data bases makes it more vulnarable for tampering with the hystory of the data as they have a central point of failoure.
  3. Digital provanance on the blockchain creates opportunities for recreating the way we conduct bussines. The immutable nature of the system offers completly transparent view of the whole bussiness process from the source, transport to the deliveries of the products in a complete trustless enviroment.

  1. By creating a digital network without any authority.
  2. Because normal database is involved with some authority or government.
  3. Digital provenance can approve without trust the original of the ingredients, also can be a stamp for original product that out from the factory.

1 a blockchain operate through a trustless decentralised ledger, no one can delete or change the transactions information
2 with normal database trust is needed. anyone can create a copy of the database info
3 all these businesses can rely on blockchain to verify the quality and the quantity of the products the buy & sell. no third party are needed

  1. Because now you can track things on the Blockchain which can not be changed or manipulated, having such things as a bar code you can see the whole journey you’re product went on, thus verifying.

  2. Because you have to trust the word of the company or handlers.

  3. Because it gives consumers peace of mind, as well as people are more likely to buy as they can see something is organic, or doesn’t use child labor for themselves.
