Homework on Provenance - Questions

  1. Transactions are recorded forever on a digital “Tablet” and cannot ever be changed
  2. Normal Database can be changed or added too or subtracted too
  3. It verifies the Digital Asset through the permanent Provenance record so there is no Trust needed…it is there for all to see anytime.

  1. How does blockchain enable digital provenance?
    By creating animmutable network where transactional information can be added, but not deleted.

  2. Why doesn’t a normal database bring the same provenance?
    Because it can be altered so trust will always be envolved.

  3. Why is digital provenance such a great benefit to many businesses?
    It can digitally timestamp transactions in real time, for both accounting and transactional information.

:sunglasses:(1) Provenance relates to Bitcoin being public and verifiable so can be trustless. Really will change auditing and will make it more instantaneous. (2) No network for verification is involved here in a normal database. (3) Auditing and transactions are verifiable and we speak of trustlessness. In other words why trust them at all if we don’t have to? “Don’t trust verify” Kind of enjoying sending in my homework properly hopefully. First timer here. “Go Hawks” USA.

  1. How does blockchain enable digital provenance?
    By making it decentralised it is essentially trustless. Authorities or government cant access or manipulate results.

  2. Why doesnt a normal database bring the same provenance?
    Normal database can be accessed and changed by users.

  3. Why is digital provernance such a great benefit to normal businesses?
    Things become very transparent, and trustlessness is achieved which is an important aspect

#1 By having a group of computers verify any type of transactions or use case.

#2 By trusting a 3rd party or less computers all you have is trust, no verification.

#3 They have more control of many aspects of their business. Also not having to rely on trust but easily verified.

  2. Everybody has access to the Data of the Blockchain, because it is public.

  4. Normal Databases aren’t public, so, only those, who obtain it are in knowledge of the data. You have to trust.

  5. Why is digital provenance such a gread benefit to many businesses?

  6. They dont need to trust, where things come from, the can simply verify due the access to the network.

  1. Blockchain enables digital provenance by publishing every single transaction.

  2. Because data can be lost, amended, deleted, manipulated etc whereas the blockchain stores the data and always adds to it, this leaves a chain of transactions at all times.

  3. Because it will allow for real time auditing saving time, money as data and transactions will always be readily available without the need for internal bookkeeping and less accounting etc.

  1. it uses a distributed ledger system to register the event/ transaction. Impossible for anyone party to dispute nor manipulate thereafter.

  2. current non blockchain registers are repudiatable if without any independent party to verify

3)it enables trust with smart contracts hence improve efficiency in essential activities between business participants.

  1. It provides the capability of tracking or tracing back
  2. Normal database doesn’t show tracking in real time
  3. Because with ability to trace back you can verify everything for yourself. You don’t need to trust data, you can verify.

  • How does blockchain enable digital provenance?
    blockchain enables digital provenance in a number of ways. First, it provides transparency. Anyone is able to see where information was generated from, from whom it was generated by, and when it was generated. Second, it is ineradicable. Third, ledgers and the structure of a network provide for the information to be veritable from multiple sources

  • Why doesn’t a normal database bring the same provenance?
    normal databases are centralized and able to be manipulated

  • Why is digital provenance such a great benefit to many businesses?
    the primary benefit is trust. if you can get a consumer’s trust, you can almost guarantee that the person (or entity) will do business with you. You do not need to rely on a third party for this incredibly significant dynamic to be created, and affirmed.

  1. How does blockchain enable digital provenance?
    • Through blockchain, every transaction contains the information of all previous transactions.
  2. Why doesn’t a normal database bring the same provenance?
    • Normal databases generally don’t include a history of all previous transactions in the transaction. That means there has to be a lot of trust that the origin presented by the last seller is accurate. It’s also possible to take things away from the database or simply omit mentioning certain things that might be uncomfortable.
  3. Why is digital provenance such a great benefit to many businesses?
    • Digital provenance through blockchain technology allows a user to verify where a transaction and all their previous transactions have come from. That means you can verify the provenance of a transaction instead of having to trust what the seller is saying.

    All transacation are recorded, immutable and publicly auditable
  2. Why doesn’t a normal database bring the same provenance?
    “normal” refers to centralised db in this case. The very nature of a centralised DB is that it is based on trust. trust the admin, the company, trust that data are not edited or deleted. in BC you can only “write”, data are immutable and trust does not exist, instead verification and consensus are used to record transactions.
  3. Why is digital provenance such a great benefit to many businesses?
    The ability of tracking the source of information provide great transparency and can boost up efficiency. Real-time auditing may be a game changer

  1. It enables provenance because every transaction on the blockchain can be verified.

  2. On a regular database transactions can be changed but on a blockchain transactions are immutable.

  3. Digital provenance can benefit businesses by getting rid of the trust factor that is common in business and instead bring a database that can verify.
