  1. By recording each transaction and making it immutable.
  2. Because it is not immutable and it is based on trust.
  3. Because it fuse transactions with accounting and you can build many layers that are encrypted and verifiable for the sole purpose of auditing and verifying the value of the transaction. Also you can audit by the minute.

  1. With blockchain you could exactly track the provenance of the transaction . The data s been written in the blockchain , nobody can remove it . Will be unremovable in the public ledger , each computer could see it .
    2.Normal database could be removed , could be erased by mistake or intentionaly .Blockchain database remaines for ever .
    3.In a business you could verify for ex. the supplier , could verify from where he buy the materials for his products .Provenance gives you mor trust , more possibilities for verify

1.How does Blockchain enable digital provenance? -

Blockchain is an immutable digital distributed database that verifies the status of something real time.

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

A normal database can be appended too or is able to be compromised due to its centralized structure. You must trust someone or some entity with validation.

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

Digital provenance allows businesses to source and verify where their products are coming from exactly. It also allows real time supply chain analysis.

  1. Blockchain effectively combines transactions with accounting of transactions making every transaction verifiable.

  2. Normal databases are centralized and require verification from some central authority like a bank for example. In order to operate in these databases you are required to trust this authority.

  3. Digital provenance is very beneficial because in a system where everything is verified, you are more efficient and do not require the same level of auditing. You can also have a trustless system so that you can track and verify things instead of just trusting a central authority on whatever it tells you is true.

  1. By storing the information in the blockchain and securing it cryptographically in a trustless way, so
    that the record cannot be changed. It is also a public ledger, so that the transactions can be traced.
  2. Normal database is not stored and secured in a trustless way, so that it can be changed, corrupted or lost.
  3. Companies can use blockchain to provide traceability and openness of their processes, like supply chains for example. Public and private information can be stored there in a reliable way. Financial transactions can also be verified quickly and reliably. Also auditing will be much easier.

  1. Blockchain enables digital provenance by being a ledger system that cannot be deleted or copied. It is verifiable.
  2. A normal database is subject to changes and based on trust. It requires users, readers, and contributors to trust those who have accessed it previously and often creates a need for an intermediate.
  3. Digital provenance cuts down on costs for businesses in various ways. Some of these cuts include removing expensive intermediates and auditors.

  1. How does blockchain enable digital provenance? >> By connecting Accounting with Transactions in a public ledger
  2. Why doesn’t a normal database bring the same provenance? >> cause someone is able to modify data or delete data, in Blockchains you only are allowed to add verified data
  3. Why is digital provenance such a great benefit to many businesses? >> you do not need big auditors any longer, because everything is stored transparent on the Blockchain + tracing of the supplychain will be possible up to 100% (if someone fixes the problem with the oracles :wink: )

  1. Blockchain enables digital provenance by making sure that the whole network has a copy of the ledger and transactions need to be verified by all of them.
  2. A nomal database doesn’t bring the same provenance as bitcoin as data can be also removed in them. In bitcoin you can only add data.
    3.Provenance is a great benefit for many businesses because there is no need to trust the source as long as it can be verified.

  1. Bitcoin enables digital provenance by being a decentralized ledger with full transparency of all historical transactions which have been verified through the blockchain network. The historical information can never be changed, therefor - all history is valid.

  2. A normal database is controlled by central authority and can therefor be manipulated and changed. Normal databases is built on trust, blockchain does not need trust, it uses validity and acts as a trustless technology.

  3. It gives the possibility for the company to have real-time tracing and auditing.

1. How does blockchain enable digital provenance?

It does by having a massive inflow of data through those,
who will be trusted to deliver that data in the future.

Imagine a “fair” traded Avocado :wink: :
Coordinates of the field they are grown, use of chemicals, storage, shipping,
more storage, trade, salaries on the whole way etc.

Seems like you can “blockchain” that data in The immutable Ledger,
but first how to convince people through the whole process to participate.
I still don´t know how to collect that data. How to tag all those things?
But i´m here to learn…

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

Trust only the statistics you fake yourself… if it is yours, yes you can!

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

Money! Fairness! Saving the Ecosystem! More Profit, hopefully for everyone…
Super nice Star-Trek-like Computersystems knowing everything, able to collect trusted data from everywhere, now!

For some reason I want to pronounce Provenance like Prove-a-nance. A things ability to prove.

The decentralized platform of computer network database constantly verifying info, the accounting and the transaction logged into ledger.

Its easily manipulated and info can be removed because its centrally controlled. Like what happened in the Housing crisis with the ledgers dealing with the mortgages. Trust is heavily relied upon.

It removes the need for trust. Trust-less-ness. Increases efficiency.

  1. Blockchain provides a transparent, verifiable way of proving transactions.
  2. A normal database is mutable and does not provide a way to verify the transacting party.
  3. Provenance can benefit businesses by providing proof, either to the business or its customers, that certain transactions have occurred.

  1. Blockchain keeps the record of all transactions and the origin of the product and the ingredients that are part of it. It traces their origin and therefore more reliable since it is trust-less, in other words you don’t need to trust the supplier but can rather verify the information.

  2. The normal database relies on trust and is opaque with the information on the product. The transactions do not reveal the origin and the source of information from suplpliers and is therefore not reliable and cannot be verified.

  3. The benefits is exactly in the fact that the companies can rely on the information regarding the quality of the product and the trust-less network. Besides, the auditing is conducted instantly and continuously and speeds up the process of transactions, records and bookkeeping. The middlemen is out of the picture and everything is more reliable, cheeper and faster.

How does blockchain enable digital provenance?
-Blockchain provides digital provenance because you can only add information- you can’t change or remove it. You do not have to rely on and trust a third party that information is correct. It’s public and transparent.

Why doesn’t a normal database bring the same provenance?
-Normal databases do not bring the same provenance because they are centralized by a third party. Information could be tampered with or incorrect information could be given and nobody would know. They rely on trust that the information coming from the third party is correct.

Why is digital provenance such a great benefit to many businesses?
-Digital provenance is such a great benefit because it provides a trustless way to be certain that your product comes from and goes exactly where it’s supposed to. This kind of confidence and transparency will assure the value of products and consumers are able to be confident of the companies they buy products from.

Homework on Provenance

How does a blockchain enable digital provenance?
The blockchain acts as a public ledger. This means that every transaction on the network is visible publicly. This allows for real-time tracking and auditing of all transactions on the network and therefore enabling digital provenance.

Why doesn’t a normal database bring the same provenance?
In a normal database, a transaction can be removed or erased, this is not allowed on the blockchain. With bitcoin, each node on the network has a copy of the blockchain and all the nodes together are able to verify a transaction. This is not possible in a normal database.

Why is digital provenance such a great benefit to many businesses?
Digital provenance allows businesses and individuals to be more aware of who they’re doing business with. Through the transparency provided by digital provenance, an individual can verify if funds are being used maliciously instead of being used for the intended purpose. Furthermore one can even verify if an individual or business is associated with or involved in shady practices.

  1. Blockchain adds data digitally and cannot be erased like engraving it on the digital stone. So, there is a track of every transaction and enables digital provenance.
  2. A regular database can be faked, erased, or manipulated and hence doesn’t provide the same provenance.
  3. It can keep a record of every single detail of the business, which can be verified at any given time. This alone adds a great benefit to many businesses.

  1. Blockchain enables digital Provenance by the fact that any additions to the chain are publicly visible and open for anyone to audit. The additions to the blockchain would also have to be deemed as true by multiple verifiers before it is written to the blockchain. Once written to the blockchain it cannot be removed and is forever available/viewable.

  2. A regular database can be edited/altered and is not necessarily immutable. a regular database is not always visible for anyone to access or hold a copy of it.

  3. Digital provenance is a great benefit to many businesses as it ads transparency and is a trustless system whereby anyone can verify the information.
