2.A normal database has transactions going through a central authority so they have the possibility of being manupilated unlike a blockchain
3.Customers can confirm things like what ingredients are in their food items, where they came from, and the quality. This would increase customer satisfaction
Blockchain uses a publicly available ledger containing all transactions. Each node has a instance of this ledger available meaning it is decentralized by nature. Validation ensures that fraud by one node in the network is not possible.
Regular databases normally support all CRUD actions and are centralized. Blockchain only allows for CREATE actions,all the while being decentralized. This causes a trail of ALL (unchanged) transactions done through the related network. Instead of changes being applied by one party with CRUD capabilities.
The main reason is “trustlessness”. Accurately deriving the history of each transactions allows for validation of facts instead of trusting another party’s statements. All without worrying about the integrity of the source of the information.

Homework on Provenance - Questions
How does blockchain enable digital provenance?
All transactions added to the blockchain can not be removed. You can trust it.
Why doesn’t a normal database bring the same provenance?
Because it is not connected/included all data. Data can also be changed removed or lost. It is not trustful.
Why is digital provenance such a great benefit to many businesses?
It will make the process much easier and shorten the lead-times. You can also trace all transactions, realtime auditing
Blockchain provided the ledger
A normal database can crash
It’s verifiable and trustless
Blockchain is a public ledger and anyone ca see transactions at any time also transactions can’t be removed.
Becouse blockchain is not controlled by anyone , normal data beses are centralized , data in normal databeses can be manipulated or removed.
Because customers can rely on that companies are telling the truth about theri produts. Customers can know from where ingredinats for food, toys, cloathes, furnitures come from. They can check all information.
By verifying transactions in real time with data that is only added and never removed.
Because a traditional database has information that can be added AND removed to reflect anything or nothing. It also does not happen in real time, which causes delays that could be avoided with blockchain.
Because everything is traceable and verifiable BACK to the source, which requires NO trust only verification from the blockchain.
Blockchain enables provenance by being immutable, as nothing on the blockchain can be removed. Every transaction is also visible and can also be traced.
A normal database can be altered as information can be removed from it. Also data can be lost if the normal database crashes. Blockchain stores information in a decentralised way allowing multiple parties to protect and verify the authenticity of the information stored.
Digital provenance is a great benefit to business because it allows for real-time auditing, and simplification of verifying transactions. This procedure helps to establish trust which is essential to all mercantile legislation.

2.In a normal database, a transaction can be removed or erased. If the database crashes, data can be lost.
3.More efficiency and costs reduction by the control of the supply chain and more important traceability is a key factor, that will reward the companies.
Blockchain is an open, public decentralized ledger where data can be added but not changed or removed. All transactions can be traced in real time all the way to origin.
a normal database requires a lot of Trust in a database that could have had data changed, added and or removed. Also the information may not always be accessible in traditional databases.
True information without gatekeepers readily available to a business is highly beneficial in terms of resources saved. Digital provenance provides real time , updated, verifiable data allowing businesses to react accordingly.
It allows for real time “auditing” of the many sectors involved. Considering it is a public ledger, it gives us the chance to not trust but to verify
Because it is centralized by some kind of entity. It is reliant on “TRUST”
In my opinion, it is great for businesses in the sense that you can enter agreements with full confidence as well as trustless risks either before or during transactions.
How does blockchain enable digital provenance?
Provenance is achieved because the the blockchain ledger is stored on a decentralized network of computers. The Database cannot be altered, data can be added but not removed from the ledger. The original data is preserved and tracked in real-time.
Why doesn’t a normal database bring the same provenance?
A normal database is not trustless, the data can be manipulated by it’s owners or infiltrated from the outside by others, therefore trust must be constantly verified.
Why is digital provenance such a great benefit to many businesses?
Digital provenance is a trustless system which creates transparency between all stakeholders.
Goods and services can be tracked and verified from point of origin to final destination in real-time. Real-time auditing, tracking financial transactions, ingredients in food etc… ,
How does blockchain enable digital provenance?
Public ledger, information is verifiable.
Why doesn’t a normal database bring the same provenance?
Trust issue. You can say that you are the best, but if only you is saying it, I don’t trust you. If 100 people are saying you are the best it’s more difficult to argue against it.
Why is digital provenance such a great benefit to many businesses?
Better recording process, reduce cost (no need for middle man), indisputable records.
1- Every transaction is recorded, set in stone, and cannot be erased or overwritten by anyone.
2- You can read and write to a normal DB. However, you can only write to the blockchain.
3- Businesses are able to verify every transaction, thus auditing is automatic and auditing as we currently know it is not necessary.
1. How does blockchain enable digital provenance?
Through the distributed ledger where data is transparent and thus all transactions can be traced.
2. Why doesn’t a normal database bring the same provenance?
Because it is not decentralized and you have to trust whereas the idea of provenance is don’t trust, verify!
3. Why is digital provenance such a great benefit to many businesses?
Preventing fraud/fake transactions by tracing every aspect of a product through the blockchain. Businesses would benefit from the transparency throughout the entire process.
How does blockchain enable digital provenance?
Because Bitcoin is a public ledger, which can only be added to and not remove. Therefore everything can be verified and that makes blockchain trust less.
Why doesn’t a normal database bring the same provenance?
Because on a normal database things can be added as well as removed and therefore fake transactions can also be created.
Why is digital provenance such a great benefit to many businesses?
It makes the process trust less and everything can be verified. I also think it can make businesses grow. Because if you can verify, more people will believe in the business.
1 - Blockchain enables digital provenance by removing the need for trust from third parties, as each aspect of a transaction is added to the blockchain and is unable to be manipulated or removed, enabling immutability. Each computer on the blockchain has its own copy of the ledger which prevents any transaction from being corrupted.
2 - Normal databases are governed by a central authority who are responsible for processing each transaction that is placed through their network, this requires a customer to trust that the third party does not manipulate or remove any transaction.
3 - Digitalising provenance allows for real-time audits to take place in a fashion that is quicker and more reliable than hiring a company. Digital provenance also allows for items to be tracked and traced at each step of the supply chain. For example, the ingriedients that are used to make a loaf of bread can be tracked from production all the way through to consumption. This allows both the manufacturer and the consumer to verify the authenticity of a product throughout each stage of its journey, this ensures safety and quality.
The blockchain enables digital provenance as it is a decentralised, open and public ledger. This means anybody is able to trace the movements of a product, or a transaction, from its place of origin all the way to its destination.
Because normal databases are centralised, it means information can be removed.
It allows the customer to check and confirm the quality of a product, therefore improving customer satisfaction. Businesses can also benefit from increased trust from their customers, by providing the quality of goods or ingredients promised.
Blockchain enables providence by storing data (through consensus verification) of all actions that occur on chain without the ability to remove the data. Basically, what happens on the blockchain, stays on the blockchain… forever.
For a normal database the governing authority has the ability to add or remove data as they please. One can only trust the “history” of the data as much as they trust the governing body. One can not verify.
Practically, it solves efficiency problems created by the need to “trust” a large number of participants. More efficient means cheaper, which is the most powerful benefit to any business. Additionally it lowers risk. A business can verify product source and transaction history with 100% certainty. This removes the risk associated with trusting third party verification/audits.
