Homework on Provenance - Questions

Blockchain and Bitcoin 101

  1. How does Blockchain enable digital provenance?
    Blockchain enables digital provenance by being a public ledger where you can add but not subtract transactions, everyone can see the recorded transactions and they are verified. They are tracked in real time and traced to precise locations in real time.

2.Why doesn’t a normal database bring the same provenance?
Normal databases can be hacked, have their books cooked, get audited, have people steal information and controlled by one party, yet I have to trust the company doing this(really? no good). Blockchain digital provenance on the other hand is trustless because everything is verified and tracked real time.

3.Why is digital provenance such a great benefit to many businesses?
Digital provenance eliminates the cost of time and money energy in having a a human auditor, receipts, mistakes and slow pace. One can keep track of a company’s inventory, logistics, foods ingredients and even populations, real time.

  1. Blockchain’s trustless nature enables people to trace products back to their origin, along with information on their state at any given part of their journey.

  2. Normal databases are generally centralised and split. Different types of related information are stored across multiple databases and are not visible to the public.

  3. Digital provenance removes the need for trust in a supply chain - if there are consistent issues it can highlight where they occur quickly. It also allows for real time auditing, saving resources that would otherwise be spent going through a manual process that could still be subject to human error.

  1. How does blockchain enable digital provenance?
    Every transaction, (old and new) that occurs on a blockchain can be traced and verified due to the underlying ledger network, in which each ledger contains an entire blockchain. Blockchain is a digital stone.

  2. Why doesn’t a normal database bring the same provenance?
    The normal database is based on trust and requires auditing, which cannot be achieved in real-time. Real-time auditing can be achieved only on blockchain, in which the process of trust is not only eliminated, but replaced by the process of verification.

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

The digital provenance achieved by a blockchain technology is completely decentralized, and cannot be altered by a bank, government, individual, hacker, or any third party. It eliminates the middle man. (Byzantine general problem)

1.) Blockchain enables digital provenance by its nature. Data can only be entered and not removed leaving a real time audit trail.
2.) Normal database does not work the same as the block chain and can be manipulated by the inputter (human)
3.) Digital provenance benefits businesses by bringing in transparency real time auditing which eliminates potential compromised data.

Hello everyone! i am new in the academy sorry if i have some grammer mistakes, english is not my native language. and i would appreciate if someone can check if I have any errors in my understanding about provenance :slight_smile: thanks!

1.blockchain enables provenance by using a decentralized data ledger that track and record all data about using in the real world.

  1. The standart database based on trust between us and someone we dont know a third party player. that can be manipulated and hacked by others. normal database is not opaque.

  2. there are many benefits in blockchain provenance that brings more value,one of them is a way to know everything that recorded in the blockchain and cannot be modified,stolen or everything else like that! and we dont need to trust a third party player,we can verify it by blockchain!

  1. Blockchain enables digital provenance due to it’s integrity and transparency. As information on the blockchain is immutable and added information requires unanimity across the network of nodes against their stored ledgers meaing manipulation of this information isn’t possible and provides real time auditing of actions/transactions.

  2. A normal database can not bring the same level of provenance because the information can be manipulated or removed.

  3. Digital provenance is such a great benefit to many businesses because it replaces trust along a supply chain with verifiable data. This has application ranging from pinpointing issues in that chain to verifying the source and quality of items along that chain resulting in more efficiency and better quality control.

  1. By recording every transaction or addition of data with NO ability to modify it afterward. All data added to the blockchain is there permanently and CANNOT be removed by anyone through any means.

  2. Because a centralized database can be modified by the organization maintaining it, which requires trust they are not modifying it. Data can be added or deleted at will, and we will never know.

  3. Because it eliminates fraud and ensures transactions actually happen, and it allows real-time auditing without hiring a “trusted” firm to verify the transactions. Information can be recorded with no ability to remove it, which gives businesses greater clarity on what’s going on. Also, transactions made over a blockchain are equivalent to paying with cash, as digital assets from one account are transferred to another in real-time using a medium that cannot be changed once the transaction is complete. There are no charge-backs or bounced checks over a blockchain, and it is difficult to lie about the content of products if all information is stored on a blockchain.

  1. Blockchain enables digital provenance through the ability to track transactions in real time. It enables real time auditing.
  2. A normal database cannot provide the same provenance because a) the information inside the database can be altered, b) the information is not real time, and c) financial & business transactions are not layered on the same database.
  3. Digital provence is a huge benefit because it allows the business, the customers, and the public the opportunity to verify at any given time the transactions of a company, be they financial, or material (eg what ingredients are in the food product, or where the materials in the clothing come from). It removes trust and makes the entire process trustless.

Answers to the Provenance questions:

1 - By decentralizing the tracking of data. So it’s not dependent on trust from a central origin.

2 - It can be modified, not trustable, and in control by a single organisation / entity.

3 - It can be trusted, and it makes everything more efficient (and so will save money)

  1. How does blockchain enable digital provenance?

The blockchain allows you to track financial transactions and put have the accounting and transactions all in one place.

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

It doesn’t bring the same provenance because the transactions a company makes and the accounting is done separately.

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

Businesses are now able to verify where there product originates from.

  1. The blockchain is totally transparent and assist digital provenance by keeping a permanent record of every transaction. Therefore no-one can change the said information.
  2. A normal database is not secure because it is stored at a central location instead of being distributed among all the different nodes which form part of the network. The risk involved is that the is not as secure and can therefore be altered or tampered with.
  3. It contributes to a trust-less inviroment which is safe, transparent track every transaction in real time.

  1. How does blockchain enable digital provenance?
    RFID or QR codes are scanned and locked in to a blockchain. This enable to trace the product history or provenance.

  2. Why doesn’t a normal database bring the same provenance?
    Because is centralised, and companies can change the data and swap RFID and QR codes

  3. Why is digital provenance such a great benefit to many businesses?
    Because the companies can deliver their original products, and the final consumer can trace the provenance of it.

  1. It ensures that a product can be tracked and traced all the way thorugh it’s inception which makes it easier for both company and buyer to verify that the product is indeed what it claims to be.

  2. Because a normal database can be corrupted because it’s not verified by many sources.

  3. It’s all about trust. If the business has many bad reviews on for example you tend to back off as a customer, but if a business can verify that the product is indeed made like they say it is then that builds trust .

  2. Why doesn’t a normal database bring the same provenance?
    A normal database is centralized. Thus, it can be manipulated.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is a great benefit to many businesses as it provides a transparent audit trail for all key business stakeholders.

  1. Blockchain is a public ledger that is permanent meaning any transactions added cannot be changed and can therefore be verified. This means a number of different computers on the network, each with a copy of the ledger, verify the transaction.
  2. Normal Databases are open to being edited or changed whereas the blockchain ledger cannot. It is also public so anyone can go in and check an entry. The database can also layer the transactional data with the accounting layer so it is simple to audit.
  3. This allows supply chains to be validated throughout the journey cycle, for example, if you are purchasing beef, you can track this from the initial point, such as the farm, all the way through to the point of getting packaged meat in a supermarket. As this cannot be altered and is subject to audit at any time you could see exactly what the age of it was, where it had been and check things such as whether the farm was a free range farm etc.

  1. How does blockchain enable digital provenance?

All transactions are written on the Blockchain and cannot be removed or changed. Blockchain makes it possible to check all transactions to its origin.

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

A normal database has the ability to removed or edit a transaction. Besides that a blockchain database is works with vericication between all connect storage locations.

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

It can be audited realtime.
