1: It enables companies to have public data that can be auditied in real time.

2: Because it is not public. So you have to trust instead of verify.

3: Because you save money for paying for auditing.

  1. How does blockchain enable digital provenance?
    Blockchain cannot be compromised therefore you can verify the data.
  2. Why doesn’t a normal database bring the same provenance?
    It’s not 100% secure, there is also a trust element involved and you cannot track efficiently.
  3. Why is digital provenance such a great benefit to many businesses?
    It’s more efficient, you can combine more layers of the business like accounting, transactions for example and it.

  1. Blockchain enable provenance with tracking the transactions into the digital network (database ) , have a proof of account layer and transaction layer and anyone can check this. It is a safe way and trustless way for payments and what is inside of that payment.
  2. In a normal database you can not add all the informations , it is very slowly and uncertain.
  3. First of all it is very fast , you can add but you can`t remove and it is a public database where you can verify the transactions.

Blockchain enables digital provenance by making everything traceable. Nobody is in control of what happens on blockchain.

A normal database has somebody behind it who can control and influence what happens on it.

Digital provenance can be a benefit to many businesses because all the facts about the business are traceable, that can lead to customers being satisfied about where the products are coming from or how they are being made.

  1. Blockchain enables provenance by ensuring a traceable origin of transferred data to and from all recipients stored on a permanent ledger.
  2. Normal databases don’t have real-time data and as high of standard protection from any data loss.
  3. Digital Provenance is a benefit because of instant transaction reliability once entered onto the blockchain, permanence of records without trust and accounting in real-time.

  1. How does blockchain enable digital provenance? - by confirming on the blockchain blocks and nodes all the transactions that conduct to the final product
  2. Why doesn’t a normal database bring the same provenance? - because it is centralized and the owner of the verifying keys is just one person, not a network/ community
  3. Why is digital provenance such a great benefit to many businesses? - because it eliminates the trust and gives you the instruments to verify

  1. How does blockchain enable digital provenance?
    By using the blockchain, items and transactions can be thoroughly tracked.

  2. Why doesn’t a normal database bring the same provenance?
    All of those same items and transactions from the blockchain earlier that we could track, are left up to the “trust” of certain, sometimes untrustworthy, parties.

  3. Why is digital provenance such a great benefit to many businesses?
    It would implement the idea of real-time auditing relieving the yearly tax headache.

1.You can add data but you cannot remove it , eliminating the “trust system” and creating verifiable transactions through a network of computers, a Public Ledger.
2. It is based on TRUST, and can be edited or easily manipulated. Hard to track where it all comes from.
3. Track and audit in real time, TRUSTLESS and transparent.

  1. By the ability of creating a digital record when transaction is completed.
  2. A regular database do not create a digital signature, and can be corrected or deleted.
  3. The digital signature created and recorded in la ledger can be audited anytime with out human coordination.

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
    By being full transparent about the information that contains

  2. Why doesn’t a normal database bring the same provenance?
    Because blockchain is encrypted

  3. Why is digital provenance such a great benefit to many businesses?
    Removes trust from process like supply chains, with digital providence you can verify the information and have real time auditing on the digital network

  1. Blockchain enables digital provenance because every transaction specific to an asset, or the item that we need to authenticate, is written to the blockchain and cannot be deleted. The blockchain is a ledger that is public, and distributed. All interested parties can have a copy of the distributed ledger. This allows all interested parties to verify the provenance of the asset, and all transactions performed with the asset, and not have to trust any one single authority.

  2. Provenance cannot be achieved in the same way with a normal database, because there is typically one owner of a database, and we would need to trust that database owner not to delete or alter transactions in the database. Normal databases can have transactions deleted by those with sufficient authority.

  3. Digital provenance is enormous value to businesses because it means they can demonstrate authenticity of transactions, assets etc to external parties in real-time (real-time audit) without the need for expensive one-time audits by independent auditors.

  1. All transactions are time, date and coded in a public digital ledger.
  2. normal databases are centralized by ppl that we must trust w/out verifing.
  3. takes away human error and corruption thru digital entries.

  1. How does blockchain enable digital provenance?
    By creating an unmutable database for the digital ledger the origin of the source of transactions is maintained. There is no one central source that is copied and can be revised but instead a constant verification of the original information and any additions. Since the information can be traced, cannot be erased and is additive there is one database that provides all of the information to be referenced.

2.Why doesn’t a normal database bring the same provenance?
A normal database is more of a collection of information that can be altered and deleted. The usefulness of a normal database is that it can be readily copied, altered and used for different purposes however it is also possible that it can become corrupted, information can be accidentally or intentionally deleted or modified and mistakes can be made in the course of database management. Normal databases have their use but provenance is difficult to maintain which is why they require governance to maintain their trustworthiness and other characteristics. I suppose the blockchain could be considered self-governing because of its provenance.

  1. Why is digital provenance such a great benefit to many businesses?
    Digital provenance means that there is one immutable source for the information available to all. I imagine this would mean that resources that would normally be required to monitor, correct and ensure the integrity of the database can be made available for other tasks. There would be no concern about versions or permissions to view the information and everyone using the database is using or seeing the same one at any point in time when they access it. The information is always current making instant tracing and auditing possible.

I wonder if this will change the ideas behind the cost of this technology much like in sustainability, where we have learned to consider the entire cost of something. For example, compare the cost of sending funds overseas through the blockchain compared to traditional banking. People talk about the cost to mine being enormous (and yes it should become more environmentally sustainable over time). However, when I have to send money overseas through the bank, I have to get to the bank (drive) as do the people at the bank, and at the bank in the other country and the person picking up the funds. Also, there has to be a physical bank, with computers and all of the infrastructure to support my small transaction. All of those costs need to be considered to truly compare. Can the energy and talents of the bank employees be put to better use making investments, helping customers with their finances or businesses or other decisions rather than handling routine overseas transactions?

The benefits to companies are that it offers new ways to handle and manage transactions and information with stable, secure and transparent processes. I think this can be applied to processes from engineering, design and manufacturing to logistics, supply chain, quality control, finance, medical impacting every sector. Even art and sports which may not readily come to mind as being affected by the blockchain.

  1. Blockchain enables digital provenance by the use of its database (public ledger) because
    the information is stored on this network of computers, then it’s trackable.

  2. A normal database is not able to store all the information as a public ledger, rather
    and this can lead to non-transparency.

  3. Digital provenance is great benefit to many businesses because it eliminates trust and
    allows for transparency, which means everything can be traced and tracked in real-time and
    not just dependent on trust only.

Provenance is essentially tracking items through time.

  1. Blockchain enables provenance by providing a transparent and concise flow of information that allows the movement of one item to be tracked over time. For example, it allows users to see where certain clothing items are made/originate, what ingredients are in their food, who is involved in a particular organization, etc.
  2. Traditional provenances can neglect or hide certain truth’s about the products that are being released into the world. In other words, there is no transparency. A classic example is one where large name-brand clothing companies own sweatshops in impoverished countries that allow them to be extremely profitable in spite of the terrible working conditions of their employees. By neglecting to show that information, consumers unknowingly participate in their bad behavior.
  3. Digital provenance is a great benefit to many businesses because it provides transparency to transactions AND people don’t have to trust one another to be sure a transaction will complete.

1.It is a decentralized system and an open (puplic) ledger where all transactions can be traced back and verified so that there is no trust in goverment,central authority,supplier etc needed anymore.

2.A normal database can be easy manipulated(remove data).The decentralized system of blockchain makes it impossible to change(remove) data.

3.It brings more transparency so that businesses can verify data and not have to blindly trust .
