1- by being an inmutable decentralized data base, blockchain can act like a trust less ledger,where all information that is stored cannot longer be changed or manipulated, while it can be consulted and audited in real time.

2- by being an immutable decentralized digital infrastructure based on hashing functions and advanced cryptography. blockchain guarantees the users that all the new transaction or information that is written on this kind of databases can never be changed or removed therefore it can be trusted.

3- blockchain has multiple benefits such as accountability, traceability, information storage, giving the customer a more reliable and transparent experience.

• How does blockchain enable digital provenance?
  It creates a unique ‘block’ of data that can be added to but nothing can be removed. Once this block has been created it is then verified by the entire chain and once verified it then appears on the blockchain as a unique record.

• Why doesn’t a normal database bring the same provenance?
  A normal database is subject to fraud and alterations which therefore renders the data untrustworthy.

• Why is digital provenance such a great benefit to many businesses?
  [/quote] Where the data needs to be trusted it offers a great solution. For the housing market for example. A house could have it’s own unique block in the chain which would detail any legal searches made against the property or who was the legal owner as a few examples. This would benefit a seller/buyer as they could trust the data without having to pay for extra legal work to verify what has already been done.

1. It keeps all transactions from the beginning of the blockchain. So each user of blockchain can easily check all data in the chain and check what was at the beginning of this chain.
2. because you have to trust this part who gave you the database.
3. It removes this part of business which is responsible for auditing information.

[ZAR]

1. How does blockchain enable digital provenance?
   Blockchain provides a list of ‘ingredients’ and cannot be altered. It provides accurate details to the interested party and is time stamped along with the transation.

2. Why doesn’t a normal database bring the same provenance?
   Blockchain lists details in a timestamped sequence that cannot be altered. The same cannot be said for other platforms. In terms of production without digital verification, materials actually used CAN differ from the materials required and/or listed.

3. Why is digital provenance such a great benefit to many businesses?
   Businesses can reassure their clients are receiving a quality product, and in turn know the specific cost of production in a more accurate manner.

[Jesus]

1. Blockchain enables digital provenance by providing an immutable public ledger which is trustless.

2. A normal database is often centralized and acts as a single point of failure, not with blockchain.

3. Digital provenance is such a great benefit to many businesses because they provide a clear view of what is really going on. There is no ambiguity with products as they are all traced on the blockchain for any and all to see.

[Ingrid]

1. How does blockchain enable digital provenance?
   It provides immutable ledger of transactions that cannot be altered and every transaction can be tracked back to its origin.
2. Why doesn’t a normal database bring the same provenance?
   In a normal database data and transactions can be removed or altered. We need to trust the owner of the database.
3. Why is digital provenance such a great benefit to many businesses?
   With provenance businesses are capable of tracing things and removing trust.

Homework on Provenance - Questions

How does blockchain enable digital provenance? By being able to track all transactions, no trust needed since all data is verifiable and immutible.

Why doesn’t a normal database bring the same provenance? Because the data can be modified, with blockchain it cannot.

Why is digital provenance such a great benefit to many businesses? It removes the need to trust, no need for it. Total transparency.

[J.Childs]

hello,
1) Blockchain enables digital provenance by each written transaction being verified by a series of networked computers that have open-sourced copies of the blockchain ledger.
2) A normal database doesn’t bring the same provenance because they are prone to manipulation. since blockchain is open-sourced (I.E open to the public) in real-time, any manipulation would be immediately identified by the network (I.E anyone with an interest in that blockchain) and not be verified.
3) digital provenance would be a great benefit to businesses by allowing the business to track, verify, and over time identify areas of concern for each assigned asset or transaction in real-time for that particular blockchain.

[SparkPath]

1. By involving transactions that are publicly available to inspection and that are also cryptographically linked in a way that makes it impossible to change a transaction that has already taken place. This makes centralized manipulation and fraud impossible.
2. A normal database can be changed and the observer or auditor would have to trust that its state has not been modified. A normal database is not distributed nor does it involve additions that are cryptographically linked.
3. It is no longer necessary for business records and auditing to be separate processes. Also, the provenance of items in supply chain can be verified by all - both the business and the customers.

[Calle_Jansson]

Blockchain enables digital provenance by being decentralized. Where no entity has complete control and cannot change/remove data as they please. Blockchain is just like you described with the “digital stone”, where data can be built upon the existing data and that the existing data cannot be removed.

A normal database does not bring provenance because there is likely an entity in control, with the power to alter the data under which they control.

Digital provenance is so great because the data can be verified and audited in real-time and has the ability to reduce the traceability of a transaction significantly.

[Crypto2revo]

1. By providing a trustless store of data that cannot be altered once accepted by the system it also is decentralized. This all allowed for real-time auditing.
2. Normal database is centralized and requires a level of trust as the governing party can alter the data. Furthermore, the date might not be readily available unlike block chain which works 24/7
3. Businesses can benefit from digital provenance as it allowed for greater transparency, accountability reliability and is a store of data. This helps customers verify if the businesses are telling the truth about a certain product. For example if a business claims that their product is organic but the transaction records shows that they have been buying synthetic pesticides.

[petra]

1. How does blockchain enable digital provenance?

Blockchain provides an immutable sequential additive distributed ledger, which can track transactions from “wallet to wallet” or within a “wallet” over time.

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

A “normal” database cannot bring the same provenance because a “normal” database is changeable. Once the verification methodology is securely established, say with a dApp to scan and enter an RFID for a product on the road, any entry onto the blockchain is set in stone and cannot be changed.

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

Digital provenance enables provenance to be tracked in real-time and shared instantaneously globally. It also allows for the data to be analyzed to help develop efficiencies in transport and production.

[Jacob_M]

How does blockchain enable digital provenance?

You don’t need to trust people, because you can’t cheat the blockchain

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

Because you can remove stuff from a normal database, where with the blockchain you can undo stuff.

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

We don’t need the middleman in the future, we are our own bank, insurance company, lender etc etc. The business can also use blockchain technology to proving originality of goods and owner ship of real estate.

How does blockchain enable digital provenance

It allows anyone to verify each transaction and each Satoshi down to the genesis block.

@ivan

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

Because a Database is Centralized and we’d have to trust the Db owner.

@ivan

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

It allows to automatically keep track of goods, money, etc. This reduces cost, increases efficiency and can further allow for more flexible workflows (i.e. re-distributing things as needed)

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?

   • Blockchain is a network of datasbases stored in inter-connected blocks and each
     block is called a leadger. Every digital stored data are traceable because no data
     can be removed nor changed.

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

   • A normal database is centralized and it’s possible to manipulate/change the
     data. Also, the auditing features are missing.

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

- Blockchain is using RT-Auditing. Companies are able to track their own supply chain etc. and can use these information to follow and improve quality control. Digital provinance offers transparency to businesses and become trustworthy for public/clients

[BtcKazman]

I have already responded to this one, but I am going back through because it has been a while.

1. Provenance is achieved due to the fact that the blockchain is not able to be influenced by any other input than that of a valid transaction. This means that the history of transactions and every transaction going forward represents a true accounting and it is not dependent on any third party.

2. Normal databases are centralized to a specific organization and all files are subject to deletion and modification.

3. Digital provenance is great benefit because customers don’t have to have trust in the company itself and know that the company is going to be held accountable to the blockchain that they are utilizing.

[leontm]

1. Since Blockchain stores all data, and is a open ledger, it’s easy for trace all digital transactions. No data can be removed and every transaction is verified by the network making it trustless and decentralized, therefore reliable.
2. A normal database isn’t trustless. It’s normally harder to trace back transactions and easier to manipulate/delete data.
3. Because it makes things more reliable and efficient. The products can be traced and accounted for easier. Removes alot of the trust involved and makes opaque industries more transparent.

[dlbc]

1. How does blockchain enable digital provenance?
   Because all transactions can be verified via a decentralised network of consensus, back to the orignal source.

2. Why doesn’t a normal database bring the same provenance?
   The transactions in a database can be altered by whoever owns the database.

3. Why is digital provenance such a great benefit to many businesses?
   Businesses can benifiet from the use of real time auditing.

[wiggo]

1. Blockchain enables digital provenance by being an open trustless public ledger where transactions can be tracked in real time.
2. A normal database is not trustless and can be tampered with.Also, normal databases are usually local, closed and proprietary, with limited external access.
3. Digital provenance eliminates the comprehensive manual paperwork associated with traditional audition, and makes it possible to automate the process in real time.

[K.Deorgins]

I. How does blockchain enable digital provenance?

By documenting transactions and keeping unchangeable and uneditable records of said transactions’ origination and their associated changing chaining history;

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

Because transactions’ records are changeable, editable, and modifiable;

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

Because the integrity of business transactions’ records are not changeable, editable, and modifiable and prevents the same as well as to facilitate real-time auditing and documentation traceability;
