How does blockchain enable digital provenance?

All transactions recorded in the blockchain are available to anyone anytime. As these transactions cannot be modify or erased, the provenance of the data can be easily verifiable.

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

A normal database is centralized and not transparent. In opposition to the blockchain, transactions can be canceled or modified at any time. You need to trust the database owner.

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

Digital provenance allows companies to trace the veracity of their supplier’s products. It also strengthens their credibility with their customers.

Provenance

  1. How does blockchain enable digital provenance?

Blockchain allows any individual a window of accessibility to verify the place of origin or earliest known history of something. This is made irrefutable by the network of individual auditors on the internet. As millions of digital auditors come to consensus the entries are recorded on a database which we call the public ledger. This data base is secure as the block chain is immutable.

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

Most traditional databases are owned by the companies they need to serve. These data bases are usually not open to the public and may not be accessible to the other companies that work with them. Normal databases are usually maintained by a central governance and can be manipulated to suit the user, ie false inputs, lost data, hidden information.

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

Digital provenance can help build trust with its consumers and stake holders. In today’s society being open and transparent is a step in the right direction as humans are becoming more and more aware to deception and corruption. Digital provenance can assist in efficiency through real time audits of logistics. It can also assist in story telling of its products. In the food industry consumers could be inspired by the people that produce their food and make a humble connection to what they eat. This would bring customer loyalty and raise the standards of satisfaction.

  1. IT allows for digital providence because the block chain AKA Leger is not erasable, you can only add, not remove information. This ledger is on many computers (nodes) spread out across the world that all need to update and verify each transaction in real time to make sure that it is accurate. False info is ignored and not added to the Chain.

  2. Normal databases are not ope to public, they are private and you can add and remove info from them. There is no trust cause you can change it however you want.

  3. Digital provenance allows for you to not have to trust anyone because the system itself provides trust (guarantees trust)

  1. Blockchain is a Distributed Ledger Technology, in which every single node on the public network track the provenance of a transaction. It’s impossible to corrupt the system, because on the blockchain you can only add new transactions, not remove or modify them.

  2. A normal DB normally hosted in one single place. You can modify or corrupt it just knowing the password to access to the DB. We don’t want a single point of failure system, so we study the blockchain… :slight_smile:

  3. A trustless system it’s critical for our society, based on data. We don’t want to trust in person or internal process in a company… blockchain guarantee about integrity of informations in real time!!

  1. Using blockchain, you can not forge or remove data. Everything is tracked and verified by other computers - making it harder to cheat.

  2. Because a normal database is based somewhere which makes it more susceptible to data manipulation.

  3. Digital provenance means that you don’t have to trust (e.g. a supplier) blindly, but instead you can verify what they claim is true, using digital provenance.

  1. By maintaining af public immutable ledger where all transactions are recorded, and chained together with cryptographic proof, that is validated by all nodes participating in the given blockchain

  2. A normal database is centralized, thus nothing prevents a central party to change the information as they see fit

  3. It will be possible to use blockhain in logistics and services where proof of existence and origin is important, such as supply chain management

  1. The DB and Transactions are complete open to public
  2. Because ite centralized and could be manipulated.
  3. Real time audititing. Traceable, transparent, redundant

Blockchain allows digital provenance by been able to track and verify things in real time.

A normal database would not have the same provenance as things can be removed from it, with blockchain every transaction has verifications from the network to prove authenticy, and nothing can be removed from it only added, making it trustless.

Digital promenance is a great benefit to many businesses because things can be authenticated quickly in real time, for example, a place where an item of clothing was first made or maybe a bottle of designer perfume, watch or make up started it’s journey, enabling a purchaser to verify it wasn’t counterfeit.

  1. All information is open in the public ledger and when written down and accepted by the community it can’t be changed or removed anymore.
  2. Normal DBs don’t need other DBs to agree what is written down an accepted as a true value. They can be copied, hacked, reset… not decentralized - one admin is always in charge of the DB.
  3. Because once written down, it will last for ever. If every birth of a child would be written down in a public ledger everyone could easily proof where he comes from / was born. It could help a lot to integrate refugees much faster or send them back.

1)Blockchain enables digital provenance by carry out both transactions and auditing simultaneously, in that it won’t be possible to change any information once written.

  1. Normal database does not have the same provenance with Blockchain because data written on them can be change, unlike Blockchain which, once written will not be changed. Normal database can also fail while blockchain cannot fail due it its distributed ledgers.

  2. Digital provenance is such a great benefit to many businesses you can trace goods from factories to shop floor and you can also know what is in the products. It eliminates the problem of trust. Digital Provenance is about restlessness.

1.open source digital ledger. Anyone can verify transactions of any sort in a blockchain.
2. normal databases can be changed at any time. Old ledgers could be rubbed out, computerised ledgers can be erased or corrected.
3. Ethical producers of products or services can be happy that their clients trust how these items are or where they are produced. Don’t trust, verify!

  1. blockchain technology makes transactions irreversible Only transactions can be added, changing or removing is not possible. Once a transaction has taken place and is described in the block chain, the origin is final and can be traced by anyone.

  2. A normal database is normally centralized and can therefore be changed, deleted or similar by a superior authority.

  3. it happens in real time and is, as described above, visible for everyone and irreversible.

1- By allowing traceability which could relate to a perceived value.
2- Centralized data. one has to trust the source .
3- By having a decentralized authority one no longer needs to trust. instead one just needs to verify.

Hello everybody,

  1. Blockchain enables digital provenance by adding transactions to all of the copies on the blockchain which can’t be removed, therefor all transactions can be tracked.

  2. A traditional database doesn’t bring the same provenance because it requires trust, which is often proven not to be a good method.

  3. Digital provenance is a great benefit to businesses because it is trust-less, it is a good way to prove the exact provenance and is great to combat counterfeiting.

Lets see :smiley:

  1. How does blockchain enable digital provenance?
    Everything is stored on blockchain and records cannot be modified for past entries. It’s also public meaning anyone can check the validity of the records.
  2. Why doesn’t a normal database bring the same provenance?
    Because you have to trust the owner of the database that it wasn’t modified and that entries are truthfull
  3. Why is digital provenance such a great benefit to many businesses?
    To checkup origins of the materials/products without having to worry whether the information is real or not. no need in trusting the other party.

  1. Blockchain records every transaction, that’s how you have a track-ability of the transactions.
  2. Normal data base relays a lot on trusting third party information which can’t be checked.
  3. Digital provenance supplying track able information, removing the trust bit.

  1. Because of decentralization companies or people can’t tamper with the information regarding provenance. Any illegitimate change in this information will be verified as just that by the network of nodes running the blockchain. Information can only be added to a blockchain database, unlike regular databases.
  2. Again, decentralization. As soon as provenance is in some way centralized it becomes more opaque, and trust is needed. Also, a centralized, regular databse is more prone to crashes and therefore more prone to information loss.
  3. It provides total transparency to customers and removes the need of trust. It is also beneficial for the company because when using a blockchain both the transaction and the provenance information is “lumped together”, removing the need for accounting.

  1. Blockchain enables digital provenance because transactions can be added, but not removed. So you cannot change the past. New transaction are verified by the network (or ignored). Also, the blockchain is visible to anyone so every transaction can be tracked and traced.

  2. In a normal database the transactions can be modified or deleted. Which means that the truth can be altered.

  3. It removes the aspect of trust between businesses. They can now verify the information they receive.
