  1. Blockchain enables digital provenance by having a transparent verifiable ledger.
  2. A normal database doesn’t bring the same provenance because is not publicly verifiable. Whoever owns the database could change the data.
  3. Digital provenance can make a more efficient financial process such as real time auditing.

  1. Provenance in terms of blockchain translates into traceability, auditability and therefore, trustlessness of data in the blockchain database. Due to the fact that blockchain is compromised of nodes containing an identical ledger on each node that represents the data on the entire network; this makes the network decentralized. As a result anyone with access to a blockchain node can trace data/transactions on the blockchain with real time auditability and trustlessness. This ability of decentralized blockchains to be verified for all its transactions with a high degree of auditability and trustlessness enables digital provenance on the blockchain.

  2. A normal database is not decentralized. It is centralized and has owners who can manipulate data without external third party observers to audit it in realtime, trustless manner as in blockchain with its public nodes. The fact that normal databases are private and have specific owners who are in charge of writing data which can be manipulated in private reduces the traceability, real time auditability and therefore, trustlessness of a normal database. Hence, a normal database does not bring the same provenance, as blockchain databases do.

  3. Digital provenance is a great benefit to many businesses as it incorporates strong trustlessness in business to business, as well as, business to customer relations. With provenance comes high levels of traceability, accountability and therefore, verification for other business or customers who want to verify the integrity of the data in a business’ database. Provenance also helps reduce the impact of resources allocated to regulating and governing data as in a trustless system decentralized regulation and governances are built into the database such as in blockchian networks.

  1. All transactions are traceable on the blockchain.
  2. Normal databases are conglomeration of attributes which able to be edited.
  3. Businesses benefit from digital prominence because of the trustless nature of the data.

  1. First, digital provenance is the ability to track or trace transactions. Blockchain enables
    digital provenance by allowing real-time tracking of of transactions of the the Block chain.

  2. A normal database is not public meaning that some one owns the database; this could be a company or a person. A normal database is administered by a central authority such as a database admin whereas the Blockchain is not administered by a single person or company; thus the Blockchain is a public ledger and all transactions are public and verifiable. A normal database is NOT permission-less because only the database admin or company is the authority and can change or manipulate the database.

  3. Digital provenance is a great benefit to many businesses because all transactions are verifiable and public in real-time, thus companies are benefiting from real-time auditing and time efficiency with the blockchain and provenance.

1)Real-time auditing

2)It can be manipulated

3)It removes the need for trust, things can be verified.

  1. It is deemed to be true and accurate. It cannot be changed. “written in stone”
    open and transparent to the public.

  2. Trust is needed, therefore, that trust can be manipulated. Do not trust… verify!

  3. 100% certainty of verification. Consumer knows exactly where material/food/ingredient is sourced. Can be audited in real time.

The BTC ledger makes digital provenance possible.
A normal database has no inherent trustless verification system.
Digital provenance is a secure environment with which to entrust critical system information.

  1. It keeps a record of all transactions and so they can all be verified
  2. A “normal” database cannot bring the same provenance because a normal database is not decentralized and it can be amended by subtracting things from that database. The blockchain acts like a “digital stone”–nothing can be taken away, only added.
  3. It enables businesses to not have to trust anyone but enables transparency and trustlessness. You don’t need to blindly trust, you can always verify.

  1. How does blockchain enable digital provenance?
    Blockchain is an immutable digital database with online transparency.

  2. Why doesn’t a normal database bring the same provenance?
    Normal databases (privately owned) can be altered and manipulated at any point!

  3. Why is digital provenance such a great benefit to many businesses?
    This creates a trust less environment enabling companies to verify any transaction financial or otherwise, creating a public ledger…Don’t Trust!.. Verify!

  1. How does blockchain enable digital provenance?
    blockchain is a ledger which data cannot be removed, so it keeps all the data traceable. also anybody has access to the data, thats why people name it public ledger.

  2. Why doesn’t a normal database bring the same provenance?
    normal database is usually centralized and not well secured, data can be removed, changed or lost. which doesnt allow to trace the transactions. in the end transactions are mostly based on trust with no possibilities to track and follow the data

  3. Why is digital provenance such a great benefit to many businesses?
    it makes customers feel more safe and confident about their transactions or whatever-food, products, clothes. also digital provenance puts businesses costs lower by cutting out middle parties.

  1. It does it through by enabling tracking and auditing of every transaction in real time.
  2. It dose’t bring the same provenance because it can be change or partly erase and It is also not fully verifiable.
  3. Digital provenance is so valuable for many businesses because it excludes the need to trust others.
    In return it gives access to full verification.

  1. How does blockchain enable digital provenance?
    Every participant in the network keeps an immutable copy of all transactions in chronological order.

  2. Why doesn’t a normal database bring the same provenance?
    First and foremost in most modern databases records can be rolled back. This alone would prevent the implementation of provenance. You also have other issues like loss of data due to corruption of the database. The blockchain is fault tolerant because all participants in the network have a copy of the complete ledger, where a database might not be fault tolerant and have only one copy of the database.

  3. Why is digital provenance such a great benefit to many businesses?
    Because for the first time it allows anyone to track in immutable chronological order things like transactions, ownership, custody, and location in a distributed, trust-less, and fault tolerant way. Any business that needs functions like this, would benefit. Good examples are finance, health care records and even the world of art.

  1. How does blockchain enable digital provenance?

It makes it decentralized, transparent and trust less. No one person or government can change the data in the blockchain.

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

A normal database is centralized. The data can be changed or altered by the controllers of the database.

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

Its great for businesses because they can audit in real time. There able to track there supply chain and what is in there product.Order product inventory automatically.

Q - How does blockchain enable digital provenance?
A - By having a copy of the blockchain on multiple computers globally all verifying the transactions

Q - Why doesn’t a normal database bring the same provenance?
A - Because transactions aren’t written in digital stone which is what blockchain provides. The blockchain is a one way entry of data so it records every transaction which can’t be changed. A normal database is centralised and can be manipulated.

Q - Why is digital provenance such a great benefit to many businesses?
A - No need for external auditors because everything is in real time on the blockchain, no need to trust a person, blockchain is trustless. With blockchain you don’t trust you verify.

  1. Blockchain is a digital database in which you can only add data and not remove data, so blockchain allows provenance to track down financial transactions, ingredients, other supplies without a centralized authority needing to get involved.
  2. A normal database is centralized, which contradicts what blockchain is all about which is inteded to be decentralized, therefore contradicts what the use cases and benefits of provenance are.
  3. With digital provenance, many businesses can trace where the ingrediants of their food came from, trace where their supplies came from, etc.

  1. Blockchain enables digital provenance because the data is encapsulated in a shared data layer that is secure & auditable.
  2. Normal databases are easily corruptible and has centralized control.
  3. Digital provenance benefits businesses because it offers security, stability, and confidence that the product is exactly what it claims to be, and has not been stolen or traced back to a fraudulent source.

A public, tracked and audit-able de-centralised database.
The accounting and transaction are held as one and cannot be edited later.
Block-chain as an example of a trust-less system and is a benefit to business as it is efficient and accurate and presents as already audited data.
A ‘normal’ database can be edited and is open to error and manipulation

  1. Because the database is built back to back like dominoes, to alter an original data piece, all subsequent pieces needs to be altered.
  2. In a normal database I can alter any part of it at any time.
  3. We can get verification of original data without 3rd parties, e.g. auditors.

  1. By allowing sequences of events to be logged in an immutable way. For instance financial transactions but also where ingredients have been and what the state was at every given point in the sequence.

  2. A normal database isn’t like a stone and can be tampered with requiring you to trust the person or organization handling the database that this hasn’t happened or to audit if the database matches other documents or proof.

  3. Digital provenance has many benefits. It allows for real time auditing and the possibility to verify instead of trusting. It can be used internally or made public allowing for a very high level of transparency.
