Homework on Provenance - Questions

Blockchain and Bitcoin 101
#4641

  1. How does blockchain enable digital provenance?
    Blockchain enables provenance by allowing each transaction to be tracked individually and then added to the open public ledger which is unchangeable and can be audited in real time.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database is centralized, subject to change, and requires trust because there is no public ledger with which to test inputs against.

3.Why is digital provenance such a great benefit to many businesses?
It does away with the need for cumbersome in-person auditing and removes the layer between accounting and transactions. It allows for full tracking of goods and services which removes the dependence on trust and the “opaque” curtain that is usually present between companies and their suppliers which overall greatly increases efficiency.

  1. Blockchain enables digital provenance by allowing exchanging of funds to combine layers of both transactions and accounting. Because Blockchain exists as a Public Ledger, these transactions can be Audited in real time.

  2. Normal databases don’t bring the same provenance from a financial perspective because there is a disconnect between the actual transaction itself and the accounts it comes from. In order to take a deeper dive behind the scenes to reveal the source of the funds or “ingredients,” audits are required. Additional, Transactions can only be added to Blockchain, not removed.

  3. Digital provenance is advantageous to many business because it removes the need for auditing departments which in turn will save many hours and dollars on man hours. If transactions can be audited as they occur, it streamlines the process of discovering where funds are coming from and going to.

  1. By connecting entities which nobody is controlling.

  2. Because humans can be corrupt and can add or delete transactions depending on what is asked from them to do.

3.Because people can see every single item where it was and what was added and the company can not hide anything, pure transparency which will this company more trustworthy.

  1. Blockchain enables digital provenance by keeping track of the transactions that occur on the blockchain and making that data unchangeable and no one can duplicate any currency because of the blockchain network.
  2. A normal database does not bring the same provenance because data on a normal database can be changed.
  3. Digital provenance is a great benefit to businesses because accounting and auditing are in an all-in-one package. Another benefit to businesses is that they can verify that their supplies and products are authentic.

1.Blockchain enables digital provenance by recording and tracking all transactions on a public ledger. This removes the need for trust.

  1. A normal database does not bring the same provenance because the owner of that data can hide or manipulate the information that can be reviewed. There is also an element of human error.

  2. Digital provenance is a great benefit to businesses because it gives them confident in their products. It allows them to know where their supply came from rather than trusting the word of the supplier.

  1. Blockchain enables provenance by keeping all transaction in an immutable data base that cannot be changed.
  2. A normal data base can be altered and is not necessarily monitored by other to prove that the date is true.
  3. Business can trust that data has not been changed or falsified.

  1. Blockchain database enables digital provenance by layering accounting and transactions together, the public ledger verifying each point in a supply chain. Like the Viking stone, each transaction can be added to the blockchain but cannot be removed (Immutability).

  2. Normal databases rely on opaque-like trust, not true verification. They can also be corrupted/lost/stolen and feature other hurdles that make tracing the transaction difficult (if possible). Blockchain simply resolves all of these concerns.

  3. Digital provenance is a great benefit to business due to it’s ability to remove the “trust” or “trustless” factor and replace it with true 100% unaltered verification. It does this through real-time auditing which is also much faster and easier and makes tracing a transaction a simply feat. Though digital provenance, businesses can purchase/sell items with confidence that they are selling/getting what they paid for, as they would possess all of the most minute details (from supply chain to end user). This builds confidence in consumers and creates a great reputation for the company thus improving market culture.

  1. The Informations are stored in a digital ledger which is decentralized

  2. A database is centralized. blockchain stores the data decentralized.

  3. You don’t have to trust a thirdparty. You trust the code. Supply chains can be tracked via blockchain

How does blockchain enable digital provenance?
Since the transaction database is decentralized and there is no single point of control, the blockchain can maintain a historical record of transactions.

Why doesn’t a normal database bring the same provenance?
Normal databases are not designed to be decentralized and typically have a super user with rights to modify the database.
this challenges the historical record as the data can be modified.

Why is digital provenance such a great benefit to many businesses?
There seems to be many applications for businesses where they would want to keep a historical record of some kind either with their partners or vendors or just internally. This increases efficiency and accuracy for a business because there is no trust needed only a transactional record that needs to be verified. This then can lead to better business practices.

  1. Blockchain enables digital provenance by tracing all transactions in real time. All transactions are recorded and cannot be deleted.

  2. A normal database doesn’t bring the same provenance because data can be deleted. Through a blockchain you can trace all transactions.

3.Digital provenance in blockchain is a great benefit to business, because there is a transparency whereby trust is not required. Transactions are verified through math.

  1. Through the use of immutability and trustlessness. the combination of these two features allow for all transactions that occurred to be traced back to the origin without being tampered.

  2. It is not decentralized, thus, the entity overlooking that database can tamper with or incorrectly manage that data.

3)Consumer confidence and trust, trustless business opening the door to working with complete strangers from around the world, traceability of all goods/services from start to end

  1. How does blockchain enable digital provenance? - The blockchain records new datapoints but they cannot be deleted, it is viewable to multiple reviews and cloned across multiple locations.

  2. Why doesn’t a normal database bring the same provenance? The information is owned by a single entity that can modify data points, and can control who has access to audit those records.

  3. Why is digital provenance such a great benefit to many businesses? - Allows for the potential or real time auditing, as well as providing greater transparency allowing for “trustless” relationships with customers and business partners.

  1. Blockchain enables digital provenance because a major component of a blockchain is the public ledger, giving you the capability to retrace every transaction.

  2. A normal database does not bring the same provenance because you can take data in and out of a normal database while the blockchain data structure only allows you to input data.

  3. Digital provenance provides great benefit to many businesses because it provides a trustless solution where trust in a third party is sought to be the only option. Digital provenance can make difficult decisions become more clear and a better overall product for the consumer.

1 - How does blockchain allow digital provenance?

The data on the blockchain is recorded sequentially and cannot be removed. In addition, they can be tracked, traced and added value by adding data in the same transaction.

2 - Why doesn’t a normal database come from the same source?

The data in a normal database can be removed, lost and do not allow aggregating more data in the same transaction.

Why is digital provenance so great a benefit for many companies?

Eliminates trust in the process, tracks instantly and generates efficiency.

  1. Digital provenance is achieved by the way the blockchain keeps a record of not just the current arrangement of assets that exist within the chain, but of the history of all transactions.

  2. Normal databases can be added to and manipulated without keeping any record of the manipulations.

  3. Digital provenance is great for a number of reasons. Two huge benefits to a business are that digital data can be easily searched and retrieved, and that writing or guiding the data manipulation can easily be accomplished by integrating existing methods used by businesses (think bar-code scanning and such).

1: what is written in a block cannot be altered due to the decentralised nature of the data & nodes.

2: they are centralised and someone with admin access will be able to alter previous inputs.

3: it removes trust so there is no need to build relationships or doubt relationships. the information is as good as it says it is.

  1. How does blockchain enable digital provenance?

Blockchain is a database that is 100% transparent, public and can be traced in real time. Data can not be removed from the blockchain. Therefore all transactions made on blockchain can be tracked and audited instantly.

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

Normal database is centralized and not public. Data can be added, removed or manipulated. It takes lot of time and effort to make an audit. It requires user to trust a database owner.

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

Digital provenence is a great benefit to many businesses because of it’s trustlessness. It’s also able to track supply chains from the very beginning to the very end. You can verify instatly origin of the ingredients, manufacturing, shipping, packaging etc. It’s always 100% accurate and can’t be manipulated.
