Homework on Provenance - Questions

  1. Blockchain is a public ledger where all transactions can be traced and tracked. Because of that people are able to see the whole information in real time. It enables digital provenance by putting the accounting layer together with the transactional layer.

  2. In normal database is a lot of trust involved. It is not really transparent because you are getting only this information which your supplier is willing to give you. The data can be changed or rewritten which is not possible on the Blockchain as you can only add data but not remove it.

  3. Businesses can get transparent about what they are doing by removing the trust factor. This can be really attractive to customers / investors as it creates a trustless system.

  1. Blockchain is like a digital rune stone. Transactions can only be added. This way the origins of a specific chain can be tracked.

  2. A normal database would not bring the same benefits because a normal database is centrally controlled. Elements of a specific chain could be eliminated or manipulated by the database authority.

  3. Digital provenance is a great benefit to many businesses because they can track and audit in real time whether the right ingredients are used etc.

1.It can be used to prevent forging of items because when is deploted on the blockchain it can’t be erased.
So you will be able to easily verify the origin of each product connected to the chain.

2.The normal data base can be faked or edited which mean that you can’t be sure about its thruthfullness.

3.The digital provenance is helping businesses by making it easier to track everything related to their work. As a supply chain of the products and accounting/auditing.

  1. By allowing the “Don’t Trust, verify” moto to be employed because it is decentralized, this allows the power to be distributed.
  2. Other “normal” databases cannot bring the same functionality of a digital provenance because they are not decentralized or transparent.
  3. Digital provenance has great benefits to businesses because it allows the smoke screens to be lifted and accountability to take place. It also gives real-time accounting that delivers direct communication allowing more control for the consumer because with more information, comes more choice and power.

  1. Blockchain enables provenance because it is a data structure that tracks and verifies all transactions via the public ledger.
  2. Blockchain’s accounting layer combined with transactional layer enables real-time auditing.
  3. Businesses benefit from the tracing directive and verification priority, removing the need for trust along the numerous touchpoints of a supply chain.

  1. Transactions can be traced in real time allowing for real time auditing creating a public ledger.
  2. Information about actual invoices is not present in the actual transaction.
  3. Having a public ledger allows for openness and transparency. Items can be tracked where they have passed and their state can be tracked when they passed through.

  1. How does blockchain enable digital provenance?
    All perminent ledger/history with verification on multiple independent nodes/computers in the blockchain so there is no one controlling entity. The ledger is only added to and no entries can be removed. Each node/computer in the network checks confirms the transaction. Also keeping track of each of transactions allows one to verified later also. And the nodes/computers are not controlled by a single entity.

  2. Why doesn’t a normal database bring the same provenance?
    Many normal databases are centralized/silo’s of information often private and/or owned by a entity [person/company/organization], most are dynamically changed/modified or truncated and you need to rely on/trust the maintainer for reliability of data. Also the data is not independently verified before adding data by multiple nodes/computers prior to changes. Often all parties do not have access to the information.

  3. Why is digital provenance such a great benefit to many businesses?
    Enables verification (you do not need to rely on trust/hope of the other party is truthful), you do not need to rely on trust that a node was not hacked/modified putting false information. The level of trust is much higher, as the independent nodes/computers would have to agree on each transaction. Finally parties have access to the data, and it can be followed in real time. Some use cases would be the: Data storage, revision control, exchange of assets, and tracking to name a few. For tracking: Food supply, medicine, supply chain, and able to watch/analyze live and in a automated way for issues. (origin date, processed, packaged, shipped, temperatuture of food/medicine, acceleration/deacceleration [like dropping], if it was kept upright [like for a refridgerator], along with when/where, and all parties could see this as it occurred and by watching the blockchain be immediately notified to all/any insterested parties.

  1. Bitcoin and other cryptocurrencies are immutable, decentralized ledgers. They cannot be falsified by a single entity. Furthermore they are accessible to everyone.

  2. Normal databases are normally maintained by single centralized entities who must be trusted.
    Blockchains are always easily accessible also in times of higher traffic (no bottlenecks).

  3. Because all data can be easily accessed by everyone, without fee or some other barrier.

  1. The blockchain technology can keep provenance by using distributed databases. Each transaction is kept in each ledge, so it is difficult to cheat on other ledges.

  2. A normal database has only one centralized database. Therefore, users cannot check the trust of the database if the owner of the database cheat on others.

  3. We do not need to pass through the central trust database. Or, it can trace the origin of the vegetables in the trusted way. People cannot cheat, so it is very trustness.

1.) A blockchain enables provenance for it serves as an immutable public ledger. This means that anything written on it is seen and can be traced by anyone.

2.) It is very easy to change a normal database

3.) It is good for businesses because it creates a reliable record of transactions. The business can guarantee, and verify, and audit their assets easily.

Homework on Provenance.

  1. How does blockchain enable digital provenance?

Blockchain enables digital provenance through a trust less public ledger … information can only be added. No information can be duplicated & is totally transparent. Its a digital stone (love that analogy).

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

Don’t trust - Verify !

There is no trust in the provenance of the information as you have no way to know whether something was changed, erased, omitted, nor can you be sure who entered or amended the data and why.

Normal database (not decentralised) = owned by a central authority and can be amended by those with control - data can be changed or erased as desired - not a digital stone !

A normal database does not bring the same provenance as it is not distributed to all parties and agreed upon in real time.

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

It takes away the need for trust in the supply chain… Users can have confidence a suppliers information is correct as a public ledger can be created from the seed of the supply chain to end user - complete transparency.

  1. It enables digital provenance by storing data/information that can be tracked and tamper proof, so that the transfer of data/information works smoothly without trust.
  2. It can’t because people,companies and government depend on the trust of other parties instead the provenance blockchain provides
  3. Because people and organisations no longer need to worry about whether their client will deliver or not…

  1. It is a decentralized database that you can only add to allowing transperacy in the form of real time auditing by anyone.

  2. Someone has control of a normal database which means they can manipulate it.

  3. It creates an incorruptible ledger of transactions allowing trust less tracking. This greatly reduces traceability time and increases efficiency.

  1. Blockchain enables digital provenance by removing trust and allows verification.

  2. A normal database is not set in proverbial stone and is not an open ledger.

  3. It is a great benefit for auditing and tracking transactions and allowing simple and easy verification.

  1. Blockchain enables digital provenance due to that entries can only be added to the ledger, thus the full history of transactions is available in the ledger, which is public. Those transactions can be verified, although not necessary because the blockchain provides trustlessness by default as every transaction is already checked.

  2. A normal database doesn’t bring the same provenance because unlike blockchain, entries can be deleted or replaced.

  3. Digital provenance is such a great benefit for many businesses because the blockchain provides permanent record keeping of all transactions, and with additional processing, can provide real-time verification and real-time accounting that is otherwise not possible using conventional means.

Blockchain enables digital provenance through the use of a public digital ledger that has both accounting and transactions together and can be audited real time. Making it he blockchain trustless where all transactions are verified.

A normal database does not provide the same provenance because they are centralized and rely on trust where another centralized database is imputing relied upon data. Not verified, not public, and accounting and transactions separate.

Businesses benefit from digital provenance because they can audit in real time and know where all of their logistical supplies are coming from and what they are as everything is verified.
