Homework on Provenance - Questions

[Jins]

1. How does blockchain enable digital provenance?
   blockchain is a digital ledger which holds the most important information and everybody can check the validity of the product
2. Why doesn’t a normal database bring the same provenance?
   a normal database can be duplicated whereas blockchain is verifiable and permanent
3. Why is digital provenance such a great benefit to many businesses?
   preventing the selling of fake goods as well as double spending

[RobertBrown1997]

1. Blockchain enables digital provenance by placing the data involved in the transaction on the public blockchain to be audited or proven in a trustless and immutable way.

2. Unless that database is on a decentralized blockchain, the data can be manipulated by the centralized actor. Blockchain ensures the data itself cannot be tampered with.

3. Everything becomes transparent to the employees, business partners, and most of all the customer. This also means the business will need to compete in a fair way with competitors, which in turn creates a genuinely better product.

1. Blockchain enables digital provenance because it is a public digital ledger. All transactions are public and can be viewed and verified by all parties. Transactions cannot be changed.

2. Normal databases are owned and centralized. This leads to issues where results can be changed and modified by the owning party.

3. This allows for tracking of all products as well as insight into the process and transactions by all parties involved.

blockchain enables digital provenance by allowing real time auditing of financial transactions.

[Sneeks71]

2. A normal database does not bring the same provenance due to the accounting and transactional layers being separate.
3. It is such a great benefit to business due to being able to track items and supplies and create supply chain efficiency

[Semicryptpro]

1. Blockchain achieves digital provenance because of its highly visible and auditable public ledger that can only be added to but not changed (digital stone).

2. Normal databases are updated with biased human hands and entries can be changed or falsified.

3. Digital provenance inherently produces a superior process or product because it indiscriminately produces a don’t trust but verify scenario.

[oftarsus]

1. The blockchain is a public ledger stored in many places simultaneously while being visible and auditable at any time by anyone with access via the internet. “It” can’t be changed, ie: all those records will always agree. Any transaction can be proven by looking at the database.

2. There’s no connection between the new inputs and the previous entries, also there is no network of exact copies of the database (programmed copies, not transcribed). Normal databases are subject to the whims and modifications of the person who adds or changes the input.

3. Provenance removes the need for trust. All transactions are visible and verifiable. Many middle-men and checkpoints can be eliminated in all aspects of business, improving efficiency, eliminating error and saving cost.

[destinydesigning]

1. The Blockchain enable digital provenance by making transactions verified and trusted using a “stone Block” which connects the longer chains; they cannot be altered or deleted. unlike…
   2 . Most Normal database, can not bring same provenance because it is centralized and data can be modified and manipulated often.
2. Digital provenance is a Revolutionary, because it ends altering and data manipulation.

[Macka]

1, Creates a trustless digital mark of the supply chain that can not be changed
2, Regular databases typically are stored in a central location and likely created within excel which makes it easy for alteration
3, Removes the need for trust of personnel within the supply chain

How does blockchain enable digital provenance?

Blockchains enable digital provenance as transactions can only be recorded and removal is not allowed, it is a digital stone.

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

A normal database doesn’t have the same provenance because normal database involves human ineffectiveness resulting errors, data manipulation, corruptions, alterations, delay, etc. In addition, it is also depending on trust. However, blockchain data is real time and indestructible.

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

Digital provenance is a great benefit to many businesses because it allows real time verification, which is the key to high performance and productivity.

[ralunascuti]

1. Blockchain allows to track the provenance of a transaction. Blockchain can only add transaction and it doesn’t remove anything because it’s a digital stone. It is also a open and public ledger
2. Because a normal database is based on trust and it can erase or remove a transaction, and this can’t happen in the blockchain.
3. Because it provides the possibility of real-time auditing, it brings the costumer satisfaction by giving them the opportunity to verify and being sure if the products are high or low quality.

[Krammyt]

Defining provenance as “The ability to track the full historical record of the creation and manipulation of descriptive data.”
Would anyone like to expand on this/refine this definition for my better understanding? I feel this best describes the more modern meaning of provenance, which is a bit more abstract than when the word was only really used for art.

1.) Blockchain enables digital provenance (provenance over digital data) by acting as a digital immutable ledger - an un-editable record of every addition of information made to that record.

2.) Normal databases cannot prove themselves as immutable, because they are usually centralized. This means that the ledger is owned by a small enough number of people/nodes that edits could be made to the data without people who don’t own the database knowing. This means that people who use normal databases have to trust that the owners of that database have not edited it - the provenance provided by the database relies on trust.

3.) True digital provenance allows businesses to remove the opacity that exists in the supply lines for whatever it is they are providing to customers. In turn, this removes the necessity of trust customers have in the business that their products have qualities desired by the customer. For example:
a.) Food being sourced with good ingredients,
b.) Ethical manufacturing,
c.) Reasonable CO2 output, etc.

[Bryson]

1. The Blockchain enables digital provenance by only allowing transactions to be added and never removed.
2. A normal database does not bring the same provenance because it requires governance and requires trust.
   3.The benefit to business of digital provenance is that instant auditing can take place, eliminating the need for bringing in an outside auditor.

[Raute]

1. digital provenance is achieved through a network where every transaction is tracked in a database(Blockchain). Every Node in this public network has a live copy of the database which cannot be altered.

2. a normal database would be prone to manipulation. Transactions can only be written to the database but not deleted

3)It provides businesses to trust less and verify with RT auditing

[Francine]

1. How does blockchain enable digital provenance?
   Blockchain enables digital provenance because each transaction is trackable and traceable in real-time in a shared/public ledger database. For one transaction to take place, the technology checks every single node in the database in every computer in the ledger to make sure it makes sense and that the amounts are correct. In other words, each transaction is audited in real time without the need for a middle man to make sure its trustable.

2. Why doesn’t a normal database bring the same provenance?
   Because we depend on trust and on having someone having to audit the process to make sure transactions are as they are supposed to be. There could be corruption.

3. Why is digital provenance such a great benefit to many businesses?
   Because it saves all the transactions history in a shared, public, safe database where the information cannot be corrupted and is verifiable by anyone at anytime.
   It allows us to verify any transaction in real time. We will not have to depend on trust or on someone else having to audit the process.
   It will make the financial processes much more efficient and fast.
   Blockchain unites accounting with transaction history in a secure, transparent way.

[Zaan]

1. Blockchain enables digital provenance by the inability of the data in it to be removed or edited. And creating an environment where data and transactions is public and opaque.**

2. Normal database is centralized and can be edited or removed by the organisation/person who is overlooking the whole system. that also compromises the quality and reputation.

3. It eliminates the need of having the audit company , all data is available and verifiable, and the process of verifying transactions is faster.

[Johnny_Watson]

1. How does blockchain enable digital provenance?

Blockchains are immutable, meaning that transactions can only be added to existing data. Each node in the network has a copy of the ledger and can verify transactions. Being able to trace and track transactions, allows for trustlessness.

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

A normal database is not immutable, meaning a central authority can edit or remove a transaction and needs to be trusted to govern the data without tampering.

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

Currently, businesses have separate layers for accounting and transacting. Digital provenance allows for real-time financial accounting layered with the function of transacting value, which means businesses won’t need to pay for expensive accounting and bookkeeping.

Businesses can immediately prove quality in their supply chain without trust needing to be established first. Equally, other businesses depending on the quality of suppliers can trace products from their origin, to verify quality, without needing to trust.

[SmilingDog]

1. How does Blockchain enable digital provenance?
   The transactions cannot be changed,
   and they may be verified in real time.
2. Why doesn’t a normal database bring the same provenance?
   Transactions may be changed, are
   subject to the reliability of the person
   entering them, and are not in real time.
3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance is like a certified
   birth certificate for all transactions. It’s
   open to the public, and may not be
   changed. Therefore, authenticity and
   quality are assured.

[SarahJ]

1. It’s decentralized, only allows data in
2. Normal.datavases are centralized and can’t be trusted
3. You can trust that the info is verified (no 3rd party) needed to audit.

[Jan90]

1. Blockchain is like a stone where every transaction is written on the blockchain and can’t be removed. Blockchain is an open ledger where every transaction can be verified.
2. The normal database is centralized, that means it can be erased, changed or hacked easily.
3. It’s more transparent, safer, there is a real-time tracking – that solves the trust problem and is more efficient.
