Homework on Provenance - Questions

Blockchain and Bitcoin 101

1.  How does blockchain enable digital provenance?

Since blockchains store all data transactions, it allows for any transactions that was done to be traced all the way back to its very first one. Once data is added, it cannot be removed or altered, and since it is open for public use, absolutely anyone can verify any transaction.

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

Normal databases use trust and good word that the information holds true. Since it can be hacked, replicated and altered, it doesn’t have the same provenance as blockchain does.

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

Digital provenance will be able to provide clarity between consumer and client. Meaning that a trust between companies and their market will be transparent and open for verification from product creation to financial transactions.

  1. Blockchain records information on a transparent public ledger that can not be tampered with…
  2. A normal data base can be altered.
  3. Because it can show everything that’s going on, the truth, without the possibility of unwanted alterations. With everything being tracked, everything being verified, nothing can be hidden.

  • Blockchain allows to track the provenance of a transaction. Every transaction is immutably written on the blockchain. Blockchain is an (open) ledger where every transaction can be traced back.
  • In a normal transactional database, records can be removed or erased. If the database crashes, data can be lost.
  • Because it provides the possibility of real-time auditing and accurate tracability, among other benefits.

  1. It is decentralized where transactions are public on the ledger. This allows any party to verify.
  2. They are centrally controlled and will be manipulated to benefit the controlling entity.
  3. Digital provenance is trustless. It allows each party to mathematically verify with out a middle auditor, saving time, energy, money.

  1. Data can only be written to or read from the chain meaning that it cannot be altered making it an ideal platform for provenance… Don’t trust verify!

  2. A normal database can be altered and therefore cannot be trusted without being verified first, way less efficient.

  3. Brings transparency and efficiency which inturn brings confidence and reliable data that can be leveraged throughout the business to improve other systems/processes.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
    In my simple explanation : by being open to everyone on earth, while being unable to modify the data after acceptence in the blockchain, its at all times traceble for everyone using the blockchain.
  2. Why doesn’t a normal database bring the same provenance?
    because there might be one entity witch controls the data and witch can do whatever it feels like with this data. It not open enough to be 100% transpartent and honest
  3. Why is digital provenance such a great benefit to many businesses?
    because the 2 obove answers, if you cant alter the facts, you cant shade it a bit. Everyone can check the facts to verify .

  1. Blockchain enables provenance by ensuring trustless transactions. It provides a decentralized ledger where transactions can be viewed and verified by all parties.

  2. Normal databases are prone to manipulations, information altering and loss and are centralized hence they cannot provide the same provenance as blockchain.

  3. Digital provenance eliminates the need for a trust based system and hence increases accountability.

1. How does block-chain enable digital provenance?

By limiting the ability to only allow new transactions to be added to the block-chain,
and preventing any previous transactions from being updated or removed.
Adding to that the ledger being decentralized, resulting in every node on the network
having a copy of the latest ledger, it is not possible for a rough node to “counterfeit”
an item as no other node will have any reference of the “counterfeit” item, and will
reject it, making the entire network in itself trustworthy and accurate.
With the information being publicly available to anyone with access to the network,
provides the ability to track a specific item from its initial starting point,
all they way to its current location, including every single location in between.
Not only can you see exactly where the item is at any given time, but also the time duration
the item was at every single location.

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

Even though you can add auditing to the database in order to keep track of all the changes being done,
you can never fully trust the accuracy / authenticity of any transaction because the transaction and/or
audit entry can still be changed or removed from the database.

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

Apart from the benefits explained in point 1;
With block-chain being a trust-less network/database, it allows a business to function more effectively
and with better accuracy, since all “variables” are either eliminated, or tracked with precision.

I think I may have gotten a bit carried away with my answers, please let me know.

  1. How does blockchain enable digital provenance?
    Every transaction is stored in the history and can be traced back to its origin.
    Transaction can only be added, not removed.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database is not decentralized and thus the hand that controls it makes us
    trust that the information is correct and trustworthy.(Don’t Trust, Verify!)

3.Why is digital provenance such a great benefit to many businesses?
It produces digital transparency and the ability to have real time tracing and accountability.

  1. Blockchain enables digital provenance by serving as a public ledger accessible by anyone and can be used to review and audit any and all transactions in real time.

  2. A normal database doesn’t bring the same provenance since traditional databases are often not transparent, have restrictions on read/write access, and can be edited or tampered with. Blockchains do not allow any kind of tampering.

  3. Digital provenance allow business full transparency of transactions impacting their business without having to spend millions of dollar on auditing services or have to trust that transactions are reported honestly and completely.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?

Because blockchain is a database that allows data to be added, but not deleted (immutable), it makes it possible for provenance (being able to trace account activity and transactions that is open to the public in real-time).

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

Because in most databases you are allowed to change the data at anytime. Some with restrictions and some without any restrictions. Anyone can change the data and their might not be any consensus if it is valid data or not. In addition, there may not be real-time auditing of the data.

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

Track anything and everything in real-time from source point to end point in full transparency that is unhindered and not tampered with.

  1. Everything that is written is immutable, can not be duplicated and is verified by the other nodes in the network.

  2. Normal databases can have date removed or copied and they are centralized.

  3. You don’t have to trust an opaque entity, instead you can verify a transparent network. The benefits could be increased efficiency, and less corruption of data.

  1. The Transactions details are verified on “digital stone” and can’t be altered. Once they’re verified by all the computers in the network this is considered verified and when details are referenced they can be observed as true.

  2. Normal database details & transaction information can be erased and edited. These are verified by a centralized entity that can be manipulated or bias toward a specific outcome when verifying a record.

  3. It does not need trust after it being verified and it is cheaper, faster and more efficient because less resources are needed.

  1. How does blockchain enable digital provenance?
    Simply put, there is a network of computers with the same database (ledger). If the information entered in one database does not match the information in the other ledgers, the information is considered wrong.

  2. Why doesn’t a normal database bring the same provenance?
    Because it is centralized. The information is controlled by one entity only. This makes it easy to cheat (i.e. modify the information)

  3. Why is digital provenance such a great benefit to many businesses?
    It is a great benefit because it allows to remove trust and, instead, verify the conformity of the data accross the network.

  1. Blockchain can allow the transactions to be tracked and the records are kept permanently. This removes the need for trust - instead you will have to verify.
  2. There are a lot of centralized database where the data can be manipulated and deleted. Therefore, it’s not transparent and it will go back to the need of trust instead of verify.
    3.It provides accurate details, can be traced and verified and cuts off the need of a middleman and the surrounding bureaucracy that comes with it.

  1. Blockchain enables digital provenance by making transaction and accounting layers transparent on a permanent ledger that can’t be altered or changed ,therefore making it trustless.

  2. A normal database is relying on a central authority that has control. Information could be lost ,changed or altered. Your relying on their trust .

  3. Digital provenance is a great benefit to many businesses because it provides real time auditing and traceability of goods from beginning to end with the full transparency of a ledger.
