1.- Since it is a database keeps all the records ever created.
2.- Because normal database is not public and can not be verified.
3.- it allows to audit in the same transaction itself, transaction and audit are not detached one from another in blockchain.
1.By being a immutable decentralized database.Blockchain can be a trustless ledger , where all information that is stored can not be changed or removed, in this way we can trust blockchain because its transparent way of tracking actions that happen on the blockchain.
2.because a normal database is centralized,and the records can be removed or edited easily , therefore is not reliable. Blockchain on the other hand is more reliable because its a decentralized database, and the records can not be removed or edited , also it works as a ledger which provides real time audit
3.because it allows businesses to track where something has been, in that way they give their customers more information with transparency
Digital provenance is enabled through the blockchain tracing all financial transactions or other information in real time on a public ledger. The data cannot be altered due to its immutability so the records are reliable.
Blockchain is a decentralised database and as such there is no one central location where it is stored, whereas normal databases are cetralised. This means that there is an individual/company/organisation which has control over the data which is recorded. This doesn’t guarantee that all records are completely accurate or permanent.
Digital provenance allows real time auditing which would be more efficient for a business instead of having traditional audits. If required, data is also available regarding the status of goods and products, background information and other relevant topics. This way businesses don’t have to trust other organisations or companies about the origins of their services/supplies and can instead verify the history by checking the blockchain’s data.
Blockchain enables digital provenance by recording every transaction, and keeps the transaction from being deleted or changed. This provides a system that can be audited with very nominal amount of time and resources. Streamlining and greatly enhancing the current system which is slow, expensive, and can have errors introduced into the audit itself.
A normal database doesn’t bring the same provenance because entries can be changed, deleted or the database can become corrupted itself. It also is subject to sources of corruption from viruses and ransomware attacks in some part from centralization.
Digital provenance is a great benefit to many businesses from the fast and almost cost free auditing that is provided through the use of block-chain VS Database structure, and it also eliminates the introduction of error during and audit.
How does blockchain enable digital provenance?
Answer: Provenance provides insight into the origins of the thing that it is made to track. With the help of the blockchain databases you will have the ability to track, trust and have transparency.
Why doesn’t a normal database bring the same provenance?
Answer: Other types databases can be changed and transparency would be an issue too
Why is digital provenance such a great benefit to many businesses?
Answer: A good exemple is a reciept, invoice or a bill of sale. The documents serve to confirm the date that an item previously changed owners, and the identity of the parties involved, such as a private owner, gallery, or auction house. This document can also serve as proof that the person owns the item they are selling and therefore has a clear title for the object that can be legally passed to the buyer upon a purchase.
Blockchain is like digital stone - new information can be added to it but cannot be removed, hence why it’s impossible to copy and paste your bitcoin (or any other kind of tokenised asset on a blockchain). The bitcoin blockchain is a public ledger - this enables digital provenance because everyone can see where each transaction came from.
A normal database is centralised, so it can be tampered with and edited by a centralised authority. Also, centralised databases are normally private, so no one else can see what’s inside them or where or to who their contents are being shared or sold. When you hand over your money to a bank or your data to Facebook, you are therefore trusting them to take good care of it. In contrast, the bitcoin blockchain is decentralised, so no single entity controls the network. Every computer on the network has to be in agreement for transactions to be verified and completed. It requires no trust, as the verification process is built into the technology.
No need for third parties to verify transactions, so companies could save a lot of time and money by getting rid of their accountants and auditors etc. Consumers can also see the provenance of the goods they purchase if their ingredients are verified on a blockchain. This would be great to stop people buying clothes from factories that use child labour, or to stop people streaming films and TV shows illegally.
Don’t trust. Verify!
Blockchain enables provenance by providing trust-less platform for storing data that is being updated in real time.
Normal databases aren’t usually interconnected because they are run by each participant separately and it is not possible to check them from outside. Normal databases don’t always carry all the date necessary for digital provenance, also because they are stored at different servers.
Because it is trust-less. It is updated in real time. Provides all the necessary data at one place.

2.Why doesn’t a normal database bring the same provenance?
Normal databases are centralized. Being centralized, they are susceptible to control and manipulation. They are not trustless, and when you have to trust someone with a database, you will never know if it is true or not. Normal databases are like living in the dark, and blockchain is the sun coming up to show you what you do not know, even when you think you do.
Digital provenance is a historical record of changes made to a piece of data over time. Blockchain enables digital provenance by documenting immutable records on a public ledger.
Normal databases require trust while blockchain is trustless.
Digital provenance allows businesses (and customers) to verify the origin and authenticity of materials/products so they can be confident that the material/product was not tampered with or counterfeit.
Homework, Provenance - Questions, July 15, 2020
How does blockchain enable digital provenance?
Blockchain technology enables digital provenance by keeping track of all transaction on the public ledger that’s built into the blockchain. Data(transaction) is stored on the public ledger, and it can’t be manipulated or duplicated. This system is trust less.
Why doesn’t a normal database bring the same provenance?
In a normal database, the system can be hacked and manipulated.
Why is digital provenance such a great benefit to many businesses?
Business can benefit by keeping track of the product on the blockchain. This will improve product quality control.
-Hector A. Martinez
When a transaction is digitally added to the blockchain, it can never be removed or altered.
Because with a normal database, things can be altered or removed.
Because it is a transaction that happens in real time, in one place and in one event. It will cut the fat out of many businesses in regard to accounting and tracking inventory.
