Homework on Provenance - Questions

[helenchang68]

1. It’s a public ledger that is fully transparent to anyone. Records cannot be edited and can be traced real time.
2. normal database are editable.
3. the transparency nature of the blockchain automatically solve the problem of information discrepancies in traditional mechanism.

The public ledger (network of computers) is immutable. While you can add information you can not change or remove entered data. Thus, enabling place of origin and/or history to always be recorded.

A normal data base, not being a network of other databases, can be altered.

Digital provenance can help business with logistics and authenticity of products.

Does anybody in here work in supply chain management? I’d like to know exactly how blockchain prevents companies from lying. Why not just claim that the coconuts used in producing a certain food is organic when it isn’t? Can’t you still get away by simple, old school lies?

There are projects that tackle this issue. I’m not exactly sure how they achieve this. A great project to check out is OriginTrail. I would suggest you check them out an ask the team

1. Blockchain is an open ledger where every transaction can be traced, no transaction can be removed (IMMUTABILITY)

2. Because normal databases can be altered and manipulated. Not like the Blockchain that as IVAN says is “digital stone”

3. Because it allows for real-time auditing

1. How does blockchain enable digital provenance?
   Blockchain is designed to be public and transparent, a leader that can be audited by all.
2. Why doesn’t a normal database bring the same provenance?
   A normal database is centralised and is therefore only able to be verified by that centralised third party. Trust of this third party is required.
3. Why is digital provenance such a great benefit to many businesses?
   Digital provenance will bring about huge efficiency benefits as well as time and cost savings for businesses. The transactional and accounting layers can be linked together in real time.

[ThomasHilton1]

1. As you said, blockchain is like a stone so every transaction that is written on it could never be erased. Therefore by storing each step of the supply chain one can verify the origin of each product.
2. A normal database is centralized so it can be hacked easily by attacking the central point
3. Digital provenance allow us to remove trust from the equation

How does blockchain enable digital provenance?

by immutability of recorder past transactions

@ivan

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

because is not decentralised

@ivan

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

because most of them are trying to do honest business, do not need to hide things

[bigtech]

1. How does blockchain enable digital provenance?
   Being a decentralized ledger, it is immutable, trustless and verifiable by nodes, it makes forgery and/or manipulation of data an impossibility. A digital provenance requires this kind of environment and blockchain is the perfect solution.

2. Why doesn’t a normal database bring the same provenance?
   normal data bases are centralized and control by certain entity or organization, and as such no immutability and data stored can be manipulated and not verifiable.

3. Why is digital provenance such a great benefit to many businesses?
   It ensures authenticity, traceability and security which any businesses would want for their product.

[MaxCrypto]

1. Data can only be written and not removed from the blockchain. Anyone can track any transaction in real-time. It puts the Accounting Layer and the Transaction Layer together.

2. A normal database is not widely accessible, it’s centralised and can be edited by the company/organisation, the Accounting Layer and Transaction Layer are not connected together.

3. It gets rid of the need to hire an Accountant, it creates a trustlessness in the space so customers know what they’re getting, thus making the customers more satisfied.

1. the ledger is public and can be tracked and traced in real time, therefore the source of every transaction can be identified immediately. Further the records in the ledger are immutable and cannot be changed or forged by an individual player in the network.
2. it is not publicly available and the stored records can be changed by admins.
3. it removes trust from the equation and businesses do not need to rely on the statements of suppliers or other players but can trace the movement of goods or ingredients on the public ledger which is verified by all the nodes.

[demdol]

• How does blockchain enable digital provenance?
  It removes the whole trust process, enabling a verification in order to achieve provenance, authentication is not influenced by dubious sources.
• Why doesn’t a normal database bring the same provenance?
  Normal databases are a single “stone” that can get updated by various sources.
• Why is digital provenance such a great benefit to many businesses?
  Connects and Increases speed between financial layers, removes physical barriers and buffers.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?

• Blockchain, “Public ledger” records all transactions in real time, can be tracked, traced and is immutable.

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

• Normal database can be altered, editable.

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

• Transparency, ability to verify, track and trace transactions in real time with immutability.

[Maki]

1. By making it decentralized where you Don’t Trust but Verify.
2. Normal database is controlled by the central authority who has the power to manipulate the data.
3. The importance of digital provenance in businesses.
   • Provide a real-time auditing which is more accurate then the manual auditing.
   • Easy to trace (the origin, location and the quality of your products at any given time).

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

1. An idea of the transactions that been sent from address to address will record to Blockchain/Database supported by many nodes around the world and the record won’t be able to change or remove later from the Blockchain

2. Because normal databases usually are not separated to many nodes around the world and require periodical backups, someone somewhere physically storing it on a server so it’s vulnerable for using and more accessible for an unwanted entity

3. Businesses don’t require any 3rd party to accelerate their valuable transaction between them securely and traceable to the public at the same time

Because blockchains are decentralized systems on the Internet and the information is only written on them and never removed, they can cary these historic data transactions on the public ledger, which are verified and traceable.

Normal databases are centralised on a single server which makes it vulnerable to attacks and not trustworthy because the central authority can interfere with it. Databases are designed in a way so that you can add but at the same time you can modify or remove data from them where as on blockchains the data is only added.

Digital provenance opens the opportunities of so many businesses that work with finances and also with companies where partners work trusting each other. In finance blockchain’s public ledger removes the need of a middle man service and makes opening account and sending/receiving money easy.

1. How does blockchain enable digital provenance?

blockchain creates an immutable ledger, copied to all nodes on the system; this enables everyone to trace back all transactions to the beginning of the blockchain

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

a normal database is able to be edited/altered, thus transaction data could also be altered

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

it not only allows a ledger and a way to trace items through the supply line, but also a built-in mechanism to audit transactions, trustlessly

[Lukas.G]

1. Because Blockchain is a public ledger where data and transactions can be stored but not erased, allowing for one to verify a certain transaction or accurately trace details of a product.

2. Because a normal database is centralized, and is owned by an organization or entity. Therefore is only accessible to them and can be tampered with. A normal database forces the user to trust whoever controls it.

3. One big reason is because it gives the business’ customers assurity over what they are getting and doing and allows them to verify themselves instead of having to trust anyone.

1. Blockchain provides an open digital ledger (database) that’s decentralized and immutable providing real time tracking of transactions. It can be added to, but never subtracted from.

2. Normal data bases are Mutable, and can be altered, manipulated, or erased by whatever governing body controls it.

3. Business can verify and validate claims in real time on the blockchain, not just “trusting” claims that someone makes.

[Nat]

1. It allows data going back to the source or origin.
2. It can have human error or tampering.
3. The business doesn’t need someone to audit the blockchain. They can look themselves to see all the transactions.

[JoeVogel]

1. Blockchain enables digital provenance by creating a digital chain of information that is immutable.

2. Normal data bases do not bring the same provenance because they are subject to change via hacking, data corruption, and data manipulation.

3. Digital provenance is such a great benefit to many businesses because their data is immutable, they can see where their products are coming from on the chain, and they can have real-time traceable data, which enables things like: real-time auditing, real-time product searching in the chain via A.I., as well as provable inventory stock and material sourcing.
