Homework on Provenance - Questions

  1. Being decentralized, once a transaction is recorded in the blockchain, it is set in stone. No single entity can alter or remove it. Everything can be traced back to the point of origin using the public ledger.

  2. We need to place trust in a normal database, that no central player will change transactions or information. It’s also vulnerable to hacking.

  3. Because auditing can happen automatically and in real time.

1- Because decentralised blockchains will enable to trustlessly track everything, whether a financial transaction, food, cloaths, the list is endless…

2- A database will enable you to add and remove transaction/data, therefore it is prone to be manipulated. A decentralized blockchain will only allow you to add, you will not be able to remove transactions from it. All open blockchain’s transactions can be tracked by everyone and then verified. On the other hand database can only be tracked by a few members and data is not transparent.

3- Because all the supply chain can be tracked and therefore be more transparent, more efficient and will tremendously benefit companies, as well as costumers as they will be able to track every step of the way of the product that they are consuming. The element of trust can be eliminated and the new motto will be “don’t trust, verify”.

  1. Because of the trustless nature of blockchain every transaction or information is verified by the whole network making it impossible to change later on. If you try to change an information or give a wrong information the whole network will disagree.

  2. In a normal database the written information can simply be altered at any time thus relying more on trust than on truth.

  3. Businesses don´t have to trust what the suppliers tell them, with digital provenance they can simply trace where an item came from and where it has been.

  1. Blockchain enables digital provenance by tracking transactions in real time. Hence eliminating trust while verifying through a network of computers.
    2.Normal data bases are centralized like voting machines in America. The data could be altered by the owner or controller.
  2. Digital provenance is essential to businesses throughout the world for trustworthiness and verifiable inventories. More Efficiencies and real time is more effective running your operations.

  1. Blockchain technology enables Provenance, in that the transactions that are being processed have to be linked with correct accounting information. For instance if i was to send you a transaction over the blockchain network then the ownership of my to be sent bitcoins are verified firstly on the public ledger. In simple words the other nodes are asked " hey does this guy here ‘own’ enough bitcoins to make this transaction ? ". If this is confirmed, then the transaction is successful, if not it is ignored.

  2. It does, you can have transaction history in a database belonging to a bank but it is centralized and not written in ‘stone’ as it would be with bitcoin. It can also be hacked and altered by a third party member or the bank itself, where bitcoin cant.

  3. They can move from a trust mindset to a verified mindset. Their customers don’t even need to trust them because it wont matter when the public ledger shows exactly how they have been moving around their financial assets.

  1. How does blockchain enable digital provenance?
    Every transaction on a public blockchain is immutable and verifiable all the way down.

  2. Why doesn’t a normal database bring the same provenance?
    Centralized databases, relational or document based, are all about data manipulation and controlled by their respective owners.
    They are not immutable by design and have no temporal constraints, because they have a different use cases and might be shutdown at will.

  3. Why is digital provenance such a great benefit to many businesses?
    Stakeholders don’t have to put trust in the business, because the public blockchain can be verified and audited in real-time when needed or automatically.
    Trust is replaced by transparency and at the same time companies can reduce costs significantly.

  1. Blockchain enables digital provenance allowing anyone to check what has been recorded, allowing anyone to record anything they want without the approval from anybody, and impedeing anybody from deleting what has been recorded.
    2.A normal database cannot provide the same because you would need to TRUST the database owner. With blockchain there is no need to trust, only to VERIFY.
  2. Business can give proof to their clients/customers that what they are claiming is true, customers can verify what business are claiming, no need to trust anybody

    By literally carving information onto a digital stone tablet, so that it will exist permanently.

  2. Why doesn’t a normal database bring the same provenance?
    Because a normal db can be altered by a central authority, like The Wizard of Oz.

  3. Why is digital provenance such a great benefit to many businesses?
    Because it eliminates trust in the system, so that businesses can focus on the relationships.

  1. Blockchain enables digital provenance by making it trust-less, meaning you can verify everything knowing it is truthful information, because everything you do on the blockchain leaves a trace that can’t be erased.

  2. A normal database can’t achieve this because it would be centralized, so you would have to trust someone or some corporation. Also in a normal database you can erase or lose information, everything written on blockchain can’t be erased.

  3. Digital provenance is a great benefit for businesses because it can help with the process efficiency. You can verify your supply chain instantly, eliminating the trust factor for your supplier, thus making your process more efficient. It can also help with auditing, since it could be done in real time and remotely, without the presence of someone in your office, since blockchain can put together the accounting layer and transaction layer.

  1. How does blockchain enable digital provenance?
    Like bitcoin, every transaction/measurement/datapoint can be followed in the ledgers which cannot be removed.
  2. Why doesn’t a normal database bring the same provenance?
    Need to trust centralized system where data risk being altered or copied
  3. Why is digital provenance such a great benefit to many businesses?
    Customer want to know what he or she is buying. Optimal environment for growing food with measurement of e.g. water, air and time. As blockchain allow for combining the accounting layer and transaction layer we know that data has been transferred, but also what has been transferred.

  1. Blockchain enables digital provenance by not allowing deletion of records and by ensuring copies of the database exist on many (distributed) systems.
  2. Why doesn’t a normal database bring the same provenance? In a normal database, transactions or parts of transactions can be removed and the “main” central database can be corrupted. Also, in a normal database, only one copy plus backups are available.
  3. Why is digital provenance such a great benefit to many businesses? Digital provenance benefits businesses by allowing automatic auditing, as transactions are innately tied to the accounting system. This saves businesses time and money, as the blockchain ratifies transactions and accounting automatically at frequent intervals, eliminating outside auditors and infrequent, invasive audits.
    Additionally, businesses can benefit from supply-chain transparency to ensure accurate material sourcing and immediate knowledge of schedule changes. This can also act as good customer assurance that the product is sourced, produced and distributed as promised.

  1. How does blockchain enable digital provenance? Answer: It is verified by each one of the people / pools of people who are running nodes on the blockchain to make sure it is verified by the data that has been recorded there.
  2. Why doesn’t a normal database bring the same provenance? Answer: A normal database is centralized and can be modified, changed, or stolen because it isn’t controlled by the user, but rather an entity that has your information stored on their servers / databases.
    3 Why is digital provenance such a great benefit to many businesses? Answer: It creates tremendous value for the business because the information is stored in one place forever. You don’t need to trust because it has already been verified by the public network of decentralized users / nodes. This can eliminate companies such as auditing companies which will save time, money and make their business more streamlined and efficient so they can work on growing and investing in other areas that will have a greater ROI using cash flow.

  1. Due to the entries in the ledger, which can be even made public, it is possible to check in time the digital provenance. The data can also be encrypted and can be accessible for a certain group, company or government. It is also immutable against changes, whereas a ‘normal’ database can just be changed.

  2. A normal database is centralized and thus the trust depends on the database’s owner.

  3. It simplifies trust by a lot! There is no need to trust a certain entity and this is huge. Also for end consumer it is super benefical, if they can see e.g. where there clothes were made at and with what kind of materials.

  • It enables digital provenance by being a public network, where you cannot hide or delete information from the community…once it is there it can never be taken out.

  • The big difference is that a normal database can be easily manipulated, thus not trustworthy

*Because it enables you to verify that all the information given to you for certain product or service is 100% accurate. It can easily be used for a sustainable and truly fair-trading

  1. To my understanding its because its a network of computers running the same protocol and they can see the source and destination of particular transaction from the beginning that its fully transparent and can NOT be erased or manipulated ,

2 . Its not transparent it needs to be verified by 3rd parties . With that being said information between multiple parties can be manipulated and changed plus information its not public .

3 . Because source of information or transaction its public and it can be verified .

By providing an open, public, auditable, platform to unalterable information that can be verified by anyone.

Normal databases can be tampered with, information can be altered, hence it requires a lot of trust. Information verification requires permission from the centralised entity who owns the database. Normal databases aren’t trustless.

Merchants and customers are able to verify the trail and origin of the products they are selling or buying. Suppliers can assure their products are originated from them.
Accounting becomes less time consuming and real time.

  1. Blockchain is a digital ledger that can trace every transaction of an asset from it’s conception to it’s end use.

  2. A normal database can be altered or hacked but the blockchain can never be changed because it resides on an entire network of computers that double check each other to agree and accept each transaction.

  3. Digital provenance is a great benefit because transactions are immediate, traceable and unchangable.

  1. Because its trust less and all transactions have to be verified by many computers. The things added cannot be removed and the computers or nodes keep the ledger from being corrupted.
  2. They believe you should trust them and believe they have your best concern in mind. It’s controlled by someone who your suppose to trust, but they can be hacked, as we have seen many times.
  3. The real ingredients , accounting , or auditing is easier to keep track of in real time, plus its always available for public eyes to see.
