Homework on Provenance - Questions

[David_C21]

1. Blockchain enables you to verify digital assets and information by tracking where they originated from and verifying if what is said about them is actually true.
   Along with keeping information transparent

2)A normal database lacks the capabilities of making things permanent, as in anyone can come in and alter/ delete information, wherewith blockchain is built into the programing where No one can and makes it extremely hard to change or tamper with the info once its live on the chain. Another way a normal database differs from BC is that BC is publicly available to everyone to access whereas on a normal database their restrictions and security hoops to jump through where someone(or company) has control.

3)This is a good thing for all businesses because it allows them to be completely transparent with the public on all aspects of their business gaining trust

1. As a blockchain is immutable, every single transaction can be traced back to its origin.

2. Conversely, a normal database is designed with CRUD, where records can be deleted as well as created, retrieved and updated as well as the whole database or complete tables can be dropped.

3. Digital provenance removes the need for trust. Therefore if a business can verify the source of supplier products and materials used in them as well as being a verifiable business itself, makes digital provenance a superb benefit for a business to show it is reputable and trustworthy.

Hi there ^^

1. How does blockchain enable digital provenance?

   By keeping an immutable ledger of all transactions.

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

   Because data in a normal database can be modified at any time by the entity managing it.

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

   Because it removes trust from supply chains, by allowing consumers to check an immutable ledger. In the broadest sense of the term, supply chains happen in basically all human activity. For instance one might check hashes against a ledger to make sure that certain data has not been tampered with.

1. How does blockchain enable digital provenance?
   The main reason is that a blockchain all transactions are saved within the chain, so every transaction is traceable. Furthermore, once a transaction is validated on the blockchain it cannot removed.

2. Why doesn’t a normal database bring the same provenance?
   Simple: In a normal database a transaction can be removed.

3. Why is digital provenance such a great benefit to many businesses?
   One of the most advantages is a real-time auditing.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?

• Blockchain decentralizes the network and creates greater accountability through its ledger.

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

• Normal databases may be hacked, erased or tampered with, unlike blockchain.

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

• It allows businesses to verify their sources, instead of having it based on ‘trust’.

[Alexiaa]

1.Blockchain is a mean to ensure the integrity of a peer to peer system. It is transparent and open source, that’s why we can find the origin of things, aka provenance.
2. A normal database is not decentralized.
3. Because they can do real time audit.

How does blockchain enables provenance ?

1. On blockchain technology , every transaction is recorded on public ledger with cannot be altered.
2. Blockchain is owned by network of computers and miners in decentralised way.
3. it allows to create trustless environment where every transaction is transparent.

[Psycom]

1. It creates a permanent un-editable record of transactions and/or information that is completely decentralised, allowing people to verify information as opposed to trusting an individual or organisation.
2. You can add or remove data from a normal database, whereas you can only add to the blockchain.
3. It provides digital transparency with multiple benefits including verification of information and much simpler accounting.

Howdie,

How does blockchain enable digital provenance?
Blockchain’s ledge (database) records all transactions from the beginning tracking ownership of something that can be used to verify authenticity.

Why doesn’t a normal database bring the same provenance?
Normal databases are centralized and with centralization trust can be faulty. Blockchain is trustless so you only have to verify. Normal databases allow you to and delete data whereas blockchain only allows you to add data keeping all the previous records pristine.

Why is digital provenance such a great benefit to many businesses? It allows you to track transactions like a bank normally does, track supply chain ownership throughout from the beginning to it’s current location.

[Taishi_Nammoto]

1. How does blockchain enable digital provenance?

• You can add transactions but cannot remove the ones.
  For example. you can scrape a letter on a stone but you cannot erase it.
• The transaction data (block) is shared to multiple computers in the world.
  No centralized database holding every transactions.
• Every transaction is open and people can verify.
  You don’t need to trust a centralized system such as a bank because you can monitor every record.

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

• The data on blockchain is not editable or deletable, while data on normal database is possible all of the actions.
  You can only add a new piece of data on blockchain.
• The data on blockchain won’t be lost due to hardware issues.
  The data on blockchain is shared to multiple computers in the world.

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

• The blockchain transparency makes companies trustless transactions.
  Every transaction is open.
• Great for businesses in developed countries because no bank account is required to create a crypt wallet.
  People who don’t have bank accounts can create a wallet and make transactions just like having normal bank account.
• The transaction fee could be a lot cheaper than bank transaction especially for international transactions.
  You can move your asset directly to another wallet without multiple country banks’ fees during the process.

• How does blockchain enable digital provenance?
  Blockchain enables digital provenance through it’s distributed and immutable ledger. Everyone can have a copy of all transitions in real time in a way that can not be edited.
  *** Why doesn’t a normal database bring the same provenance?**
  A normal database doesn’t bring the same provenance because transitions could be edited or deleted, and its not open source,
  *** Why is digital provenance such a great benefit to many businesses?**
  I believe digital provenance is such a great benefit to many businesses because it dramatically reduces the time and cost of auditing, fraud would be discovered sooner, they would know the origin of supplies, and most business can realistically switch to the specific ID accounting method allowing them to target recalled goods, etc.

[rebeccawatkins16]

How does blockchain enable digital provenance?

You can embede a digital signature which demonstrates authenticity.

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

Data can be removed.

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

Because of many innovation opportunities.

[JComes]

1.Blockchain enables provenance by recording transactions and ownership in a transparent manner. Through blockchain we are able to verify the origin and authenticity of a transaction without having to rely on trust. Transactions and ownership are directly verifiable and knowable, nothing to guess.

2.Normal databases do not bring the same provenance, because the database is not immutable, it relies on trust of the database owner and it may be difficult to verify the origin of the data/transactions/ownership. If the database fails, all information may be lost.

3. Digital provenance is a great benefit to many businesses, because a business can directly verify input and output without relying on, or simply does not have to trust that data is correct. A business can verify a process in realtime.

[Karanam]

1. Every transaction is written on blockchain and will be immutable. So the trace can be trusted.
2. Normal database is not immutable. So, traces cannot be trusted.
3. Brings in transparency and control.

All transactions can be tracked (audited) on the public ledger.

A normal database can be modified. It is under control by the central company.

It allows businesses to be trustless. People are able to track money, expenses, ingredients etc.

[prakashmech1]

1. Blockchain enables digital provenance through a public ledger where anyone can verify the origin and no one can manipulate.
2. Normal database maybe controlled by a trustworthy person where we don’t have the trust on them unless you verify every time (practically not possible).
3. The real value of the final product delivered to the end user is audited by the system through verification through out the process and not by trust.

[nick996]

How does blockchain enable digital provenance? It records everything on blockchain ledger and it is immutable.

Why doesn’t a normal database bring the same provenance? Database is central and one authority can change the data.

Why is digital provenance such a great benefit to many businesses? We can record all the steps and verify the truth.

• Why doesn’t a normal database bring the same provenance?
• Why is digital provenance such a great benefit to many businesses?

1- By storing all data in the public ledger and replicating it throughout the nodes, modification of data is not possible.

2- Because a regular database is not immutable. It can be altered and manipulated. Blockchain is immutable.

3- Because all data is publicly verifiable in the blockchain, therefore no need to rely on third parties to audit the business.

[Mirthis]

@ivan

• How does blockchain enable digital provenance?

By providing an immutable ledger of all the transactions, meaning that is always possible to build an accurate history of the events

@ivan

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

Many time the way data are stored means that historic provenance get lost over time. Even when this is not the case the data are still subject to tampering

@ivan

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

Cause it provides traceability for the assets involved, transparency when the data are public, security as data cannot be tampered or changed

[edagili]

1. How does Blockchain enable digital provenance?

A. Blockchain enables the business to easily collate their data along with open data and also verify key information.

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

A. Normal databases are not immutable and entries can be changed by the owner.

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

A. Businesses can perform real time audits and as a result real time analysis of data which does not need to be verified and which therefore leads to more efficient decision making.
