  1. How does blockchain enable digital provenance?
    Blockchain is a database, a digital ledger, where data can be added but not removed. And it’s public, so it is decentralized that way everybody can trace back the origin of every transaction.
  2. Why doesn’t a normal database bring the same provenance?
    In a normal database data can be added and removed. And it is most of the time centralized. This means that using this database is based on trust.
  3. Why is digital provenance such a great benefit too many businesses?
    Digital provenance means, in the relationship between a business and his client, trust is not relevant anymore; every step in the process can be verified.

  1. How does blockchain enable digital provenance?
    The network is decentralized and creates a trustless record! Transactions can not be removed only added to the record. No person or single entity is in charge of the record.

  2. Why doesn’t a normal database bring the same provenance?
    Most databases have an administer or several people who can manipulate the record. The database might get hacked or crash therefore destroying the accuracy of the data.

  3. Why is digital provenance such a great benefit to many businesses? It will keep track of live data.
    This will eliminate the need to hiring people to audit your business.

1] Blockchain enables digital provenace by the community running their computers that verify transactions between two parties, creating a historical record of the same transaction. then the record of information can be trusted for validation and audit purposes.

2] A normal database does not bring the same provenance because it is centralized and runs only on trust. It has been shown that these same company’s that run the normal database has misused peoples trust in them.

3] Digital provenance is a great benefit for many businesses as they will be able to improve quality control and auditing.

  1. It lists all activities that take place on the ledger in an orderly and sequential manner. Therefore you need only connect the dots to see what happened.

  2. Because databases can be erased. What is registered on a blockchain cannot be altered.

  3. It allows audits to happen in a very logical and easy manner.

  1. All transactions are recorded and added to a public ledger/database that cannot be changed once verified and all transactions are public and verifiable.

  2. Normal databases are usually owned by a single entity or small group, usually the database is manipulatable and oftentimes not public.

  3. Don’t have to rely on a single auditor. The trust is baked into the blockchain through math.

  1. How does blockchain enable digital provenance?
    You can only add to a blockchain, you can’t delete and so it creates a permanent record of transactions. This feature provide full traceability of transactions and allows you to merge the transactional and accounting layers. It’s not just confined to financial transactions however, in the example of food ingredients it enables you to identify the origin of an ingredient and the trail of those ingredients throughout the supply chain.
    In short, it enables you to track and trace something back to its origin.
    The blockchain is also a public ledger and therefore can be inspected, audited and analysed by anyone which helps to prevent fraud and builds trustless systems.

  2. Why doesn’t a normal database bring the same provenance?
    You can delete and modify data in a normal database, also a normal database isn’t public.
    This means you can’t track something like a financial transaction easily, you also can’t audit it as easily and it can be tampered with and modified.

  3. Why is digital provenance such a great benefit to many businesses?
    The slogan Don’t Trust, Verify represents this in my opinion. It means businesses don’t have to trust the information they have been, say from a supplier, they can verify it themselves. This brings great power to many businesses but also accountability to others.

  1. All Transactions are recorded on a public ledger that is verifiable.
  2. It can be changed by a 3rd party and relies on trust not verification.
  3. It allows all things to be traced in real time. Ingredients, labor, location, auditing.

  1. There are several copies of the “data” to verify authenticity. Not just one central location.
  2. A vast majority of transactional databases and systems utilize a CRUD model. The Create and Read is what we have with blockchain. However, when you are able to access data via a key, and give the user the ability to Update or Delete a record, you have now given the user the ability to change the data, and therefore “void” the actual data. You can log update and delete transactions, but now you are relying on the developers to handle processes. An un-modifiable ledger removes this ability.
  3. You have a built in audit of the detail of the process and the individuals involved.

  1. Blockchain enables digital provenance by it´s transparency system. You can only add to blockchain, and can´t delete. It´ s not only great by auditing financial data like transactions, but also like tracking physical goods. Blockchain is digital ledger that is decentralized and trustless. Anyone can verify the data and make sure that all is legit. You can´t fool the system.

  2. Normal databases aren´t decentralized, and can be manipulated by humans that have control of that systems. And also there is high level of trust involved on human behavior.

  3. It brings real time auditing, and costumers alone can see and verify the origin of transaction or some physical good.

  1. Through public distributed ledger where a copy of all transactions are recorded simultaneously at multiple computers, all nodes that comprise the network, stored forever, can not be erased or modified, and available for the public at any time as a full copy to trace all transactions that ever took place

  2. A database is centralized, it can be modified, it can crash, it is not public, administrator can modify, there is no multiple nodes that have to verify , data can be deleted

  3. Provides transparency, enables immediate auditing, eliminates the need for trust - don’t trust - verify!

  1. It keeps a transparent record of every step of a transaction
  2. Because it is centralized and not usually transparent
  3. It verifies each and every transaction, or each and every component of a series of transactions - like the various locations a product is transported across (place/time) on its way to customer.

I see I left out one major component: a regular database can be edited the Blockchain cannot be edited - no transaction once verified can be altered or deleted. No tricky business!

How does blockchain enable digital provenance?
Blockchain is like a runestone that it can only be added but cannot be erase or change.
2. Why doesn’t a normal database bring the same provenance?
Normal database is centralized and is heavily depends on one authority or government which database can be altered due or destroy to corruption and machine failure.
3. Why is digital provenance such a great benefit to many businesses?
Digital provenance provides speed and productivities because it eliminated the process of trust. It can be proceed without questioning the database.

  1. BC provides provenance by combining the steps of recording transactions and accounting to the same digital process. All aspects that contribute to the creation of a product are recorded and available for review.

  2. A normal database lacks the same provenance because the data is held across multiple systems of recording. Audits are required to compare the multiple sources of data to confirm accuracy. This is inherently less transparent than a combined BC system of record keeping.

  3. Business benefit from increased provenance by reducing record keeping costs. Auditing is not necessary, or maintained continuously. A business can also provide improved customer trust levels through higher degree of operational transparency. This is of best advantage for public relations between a business (it’s image) and its customers.

  • On the blockchain, it is able to write ( add) but not able to remove it. Every transaction made is traceable and is transparent.

  • With a normal database, it is possible to remove data. So in that case, it is not 100% sure that what is in the database is the factual truth.

  • For businesses, it could mean that it enhanced traceability. It can be traced to what ingredients are in a cosmetic product.

1. How does blockchain enable digital provenance?
The blockchain creates immutable records on the ledger whereby all transactions/ actions can be tracked and traced (in real time), and need to be verified by the network.

2. Why doesn’t a normal database bring the same provenance?
Normal databases are centralized, meaning that the power lies with the owner of the database, and other parties need to trust what the database owner has communicated. The owner of the database (and the holder of power) is able to manipulate the data if it serves their agenda, and the network does not need to be notified of these changes.

3. Why is digital provenance such a great benefit to many businesses?
Firstly, it creates a layer of efficiency as the auditing happens in real time, without an additional processes such as external auditors adding an extra step.
Secondly, it creates transparency. There is no need to trust any of the parties as everything is verified by the network. In turn, this also contributes to efficiency as companies don’t have to spend resources and human capital trying to do these verifications themselves, and can rather focus on spending their capital on their core business.
