#4981

  1. How does blockchain enable digital provenance?
    All transactions can be traced, tracked and audited in real time.

  2. Why doesn’t a normal database bring the same provenance?
    Because their current transactions can not be audited in real time. Accounting and transaction layers are messed with blockchain

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

Many things businesses say or know about their products involves a lot of “trust”. A public ledger can tract businesses products and the state of those products in the supply chain in real time.

  1. Blockchain allows digital provenance by using a decentralized ledger to gather and store all transaction history. The data on the blockchain is permanently stored, transparent and immutable.

  2. A normal database doesnt have the same provenance because it is centralized and therefore leaves room for a number of issues. Issues include Data breach, lost records, stolen info, leaked info, altered figures.

  3. Digital provenance is a great benefit to businesses because it is trustless and verifiable. The time to verify data can be reduced to seconds.

1: you are always able to track live and real time movement. All data is verified (not able to change)

2: In a normal database you are able to add and remove data and that makes it relieable on trust.

3: It is fast and easy to track. It is cheaper because you skip a thirdparty and then you dont need to trust a thirtparty

  1. How does blockchain enable digital provenance?
    By being able only to add information in the blockchain and not remove it. You can always verify from where the actual information came from.
  2. Why doesn’t a normal database bring the same provenance?
    A normal database cannot bring the same provenance because it cannot guarantee that the information in the database has not been changed over time.
  3. Why is digital provenance such a great benefit to many businesses?
    Being able to constantly verify the provenance of different assets you eliminate the trust-issues related to this. You basically cannot cheat or manipulate what goes in, what goes out and where it came from.

  1. How does blockchain enable digital provenance?
    by being public and permissionless blockchain allows transactions to be traced and tracked (data can be reviewed, but can’t be changed)
  2. Why doesn’t a normal database bring the same provenance?
    as it wouldn’t be public it would be difficult to verify, you would blindly have to trust and accept it.
    besides we wouldn’t know if that data base was altered at some point in the past.
  3. Why is digital provenance such a great benefit to many businesses?
    by being able to verify the provenance of their transactions Businesses can proove whether they have and issue or not, and custommers can even verify it themselves.

  1. By being entirely decentralized and due to the fact that the ledger containing all necessary information is public. Anyone can go in and verify or dispute information digitally.

  2. Because normal Databases are governed by central authorities who are able to make their own decisions, in their own interest, about the data contained in the database. New data can be written or deleted by a centralized authority, and the simple possibility of this decreases the functional value of such a system.

  3. Because it offers customers satisfaction knowing their transactions can be verified in a truthful manner and they can trust that their information, money, or other resources are properly allocated as they want them to be.

  1. Blockchain allows to trace every transaction with provenance, and it is shown in plain sight all movement that was made. Transactions cannot be removed or altered, and it is a open ledger which means that we the users can trace transactions without a third party service.
  2. Data can be changed, and we have to give our trust to third parties businesses.
  3. It is the only source that is reliable in which duplication is not part of the equation, and it is real-time efficient.

  1. Blockchain enables digital provenance by validating data between businesses. Data is stored in a ledger that is read only and available to the public

  2. A normal database is centralized . The data is read / write and it can be modified

  3. It enables trust between businesses.

As beign decentralized database blockchane is removing trust as its not neccessary any more because focus is on verification. Trustnessless is key word.

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

Because normal data bases are duplicable and editable.

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

Because everything can be traacked and origin found. Everything is stored on ladger and be looked at.

  1. How does blockchain enable digital provenance?

The blockchain is a decentralized and distributed public ledger which records all bitcoin transactions chronologically and immutably. Immutability ensures that once a record is recorded and accepted across the network, it can no longer be altered. As such, this enables one to trace the life of a record from inception to present state thereby enabling digital provenance.

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

Normal databases tend to be centralized and permissioned based such that owners can edit records that were previously inserted. This presents challenges in ensuring integrity of a record’s lifecycle.

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

It ensures the integrity of the products and their corresponding dependencies across the entire supply chain, leading to higher reliability and removes the need for trust because the blockchain is easily verifiable.

  1. How does blockchain enable digital provenance?
    Because every single transaction is stored and on record every single person can see from their computer where the transaction is from. These transactions are immutably. Therefore the blockchain is completely transparant. This is why the blockchain enables digital provenance.
  2. Why doesn’t a normal database bring the same provenance?
    Normal databases are centralized and the information on it can change everything which is on that normal database. This database doesn’t have the verification that the data on the blockchain has. Therefore the information on the normal database doesn’t have to be correct. While on the other hand information on the blockchain is immutably and verified.
  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is a great benefit to many businesses because of the transparancy and reliability it provides. This way a company or a customer can exactly track where a product is from and whether or not the information which is provided is true.

  1. Blockchain is a public, decentralized database/ledger or runestone which anyone with an internet connection can access by downloading the Bitcoin client on bitcoin.org - although make sure you have an external hard drive before downloading and playing around with it as it is 330 GB currently.

This Bitcoin client in turn downloads the blockchain ledger which includes all the transactions in the blockchain network that ever occurred and through it people can practice provenance as everything is public and the history of ownership or of a product can be easily traced back to the previous owner.

  1. Normal databases are -as far as I know - mainly private. They are also centralized and managed by people instead of computers as in the example of blockchain meaning that they are susceptible to human faults, corruption and exclusion of information that is deemed by the centralized authorities managing the database either as “not required for public viewing” or can be seen as damaging to the entity if it goes public and gets known by external stakeholders.

  2. It eliminates faith and need for trust in just words of partners, suppliers, governments and other stakeholders as it is allowing the business to verify where and how their products were developed, where they came from and under which conditions the raw materials became the finalized product.

How does blockchain enable digital provenance?
Blockchain records every transaction in a public ledger. It is not easy to change the existing information and everybody can see this information from their computers. The information is available almost immediately as well.

Why doesn’t a normal database bring the same provenance?
The data in a normal database can be changed by the people who have access to the database. It is also almost impossible to remove information in a blockchain as long as the internet exists.

Why is digital provenance such a great benefit to many businesses?
There are many businesses whereby information is not accurate, or based on the trust of a person or organization. Digital provenance removes the trust factor and the information is made available for anybody to check.

1_Every transaction can be tracked and traced (in real time if need be), by anyone due to the public nature and spread of the nodes. The internet serves as a sort of notary. This information cannot be erased or tampered with.

2_Centralized databases are vulnerable to outages, tampering, hacking, spilling of coffee on the servers, etc. This does not ensure a safe and transparant transaction between point A and B. no independant party is privvy to these transaction, and thus no verification except the trust between both parties.

3_ All parties involved can verify multiple layers of a transaction, cutting out third parties, reducing time and costs, and there is no need for blind trust.

  1. Blockchain enables digital provenance as it is a ‘digital stone’ which means it is an incorruptible store of a data, a ledger. This open network of stored transactions allows for complete transparency in any supply chan.

  2. A normal database does not bring this kind of provenance as it is centralized, therefore it can be manipulated and corrupted. Also it relies mainly on trust and not digital fact.

  3. Digital provenance is of great benefit to many businesses in the modern world as it has many use cases. Mainly it can be used as a supply chain mechanism that allows for more security, safety, integrity and all in a trustless environment.
    ‘Don’t trust, verify’.

  • The blockchain is a distributed ledger wherein every step or transaction within the value adding process can be traced based on the historical database and origin recorded/written on it which cannot be removed.
  1. Why doesn’t a normal database bring the same provenance?
  • A normal database, can sometimes be vulnerable or manipulated that can crash, resulting in data lost. Traceability can sometimes be difficult due to inconsistency in the database.
  1. Why is digital provenance such a great benefit to many businesses?
  • High accuracy of data with real-time monitoring, auditing and traceability, are some of the benefits.

  1. Blockchain enable digital provenance through its ability of acting as a public ledger for the whole world to see and track its origin just by the use of internet. It enables a trustless community.

  2. A normal database usually operates on the basis of trust whereas in blockchain technology it is not all about trust but verification is as of more importance. Don’t trust but verify!

  3. It is a great benefit to many businesses because if they know how to use it well, they could save cost on the middle person which is usually auditors. Auditors is very vital to each business as they will determine whether the company is trustworthy. With the use of the blockchain technology, auditors are not needed as all the verification and data stored is in the blockchain itself.

  1. Blockchain enables digital provenance by ensuring accurate traceability (i.e. verification) in real-time of all financial transactions, thereby extinguishing the need to rely upon trust. For example, if we take the Bitcoin network as an example, one can trace the transaction history and movement of each and every single bitcoin (or even satoshi) all the way back to when it was first mined (i.e. the original source/provenance of said bitcoin).

  2. A normal database doesn’t bring the same provenance because it depends upon trust in that one must trust that information has been input accurately on the relevant database. As we all know, standard databases can be manipulated (e.g. by entering false information, whether erroneously or purposefully (i.e. if the database is hacked)). In contrast, a blockchain database cannot be manipulated or falsified because it is publicly verifiable (one block at a time) by all of its users.

  3. Digital provenance is such a great benefit to many businesses because it extinguishes the need to rely upon trust (especially in regards to supply chains). For example, food manufacturing companies can verify the source of their foodstuff supplies if the movement of such items is recorded on a public blockchain (i.e. a ledger). Moreover, digital provenance reduces innovative companies’ dependence upon the traditional big four auditing companies.

  1. How does blockchain enable digital provenance?
    Blockchain is an immutable database and will always show the history/provenance.

  2. Why doesnt a normal data base bring the same provenance?
    A normal data base is centralizes, can be added and changed and can be corrupted.

  3. Why is digital provenance such a great benefit many businesses?
    Digital provenance enables tracking and tracing of different steps of block chain, supply chain. You can verify in real time and you don´t have to trust in to your previous suppliers. It enables to have trustlessness, in the positive sense.
