  1. Due to the nature of blockchain, every transaction can be verified since all transaction are stored on the block, and cannot be removed
  2. A normal database isn’t necessarily immutable
    It has to be decentralized (everyone must have their own copy of the database)
  3. They no longer need to rely on the trust customers give, they can verify it themselves to prove their integrity

  1. How does blockchain enable digital provenance?
    A blockchain is designed to locate historical records that have been verified.

  2. Why doesn’t a normal database bring the same provenance?
    Because usually normal databases are centralized and the information in them might be questioned since it required a central location/source.

  3. Why is digital provenance such a great benefit to many businesses?
    No third party involved. No trust required just verify.

Blockchain enables digital provenance because it is a public ledger that cannot be changed, is verifiable and traceable in real time.

A normal database does not bring the same provenance because it is centralized and able to be controlled and manipulated by single entity.

Digital provenance has many great benefits for business. It brings transparency, makes it possible to bring together accounting and transaction layers in real time thus reducing or eliminating the need to bring in auditors. It provides a trustless environment, can provide details, accountability, traceability from source to shelf. Gives business an opportunity to run more efficiently and profitably.

  1. Becos each transaction can be tracked or verified in real time.
  2. Becos normal circumstances there is a transaction layer And there is an accounting layer. Errors or ommissions can occupant in dither or both layers. There also needs an element of trust. But in this digital runestone, non of these issues surface.
  3. No trust needed, as all transactions are traceable and verifiable in real time.

  1. By allowing for real time tracking. Traceability

  2. There’s no central controlling authority who can alter data within the database. Data can’t be removed, only added unlike the regular database

  3. It eliminates the need for trust. All data can be verified mathematically

  1. Blockchain is a public ledger that cannot be changed, it is verifiable and immutable. You can only add information to the blockchain and information can be traced in real time to verify.

  2. A normal database is centralized and it requires the central governance to be trusted and not be corrupted or subject to manipulation. In addition, a lot of effort is needed to ensure the central database ( or Cloud database in case of the cloud model is) is secure; administrators have the least required access and are trustworthy, and information is backed up.

  3. Real-time auditability, transparency as a public ledger, and verifiability. Being trustless in nature, it allows businesses to transact with a piece of mind.

  1. All transaction on the blockchain are recorded and can be added only not able to take away.
  2. The decentralized attributes add security as people can not take anything away only add the verification adds another layer of security to transactions.
  3. The trust that can be attained through the process.

1.provenance allows transparency, every transaction is visible and is not able to be deleted or manipulated because of the blockchain. Also it is public so anyone and everyone can see and check the data for reassurance.

  1. A normal database can be manipulated because they have a central authority that is in charge of the database they can remove or change transaction unlike blockchain, every transaction on the blockchain is recorded, verified and cannot be removed. provenance removes the “trust” from each transaction, because you can audit each and every transaction in real time

  2. digital provenance is great for business because it shows the customer or user exactly what they are getting, it offers transparency and assurance. there is no need for trust because every transaction has been verified and is not able to be manipulated or erased.

1. How does blockchain enable digital provenance?

Blockchain creates a “trustless” system that can be verified without relying on another party. This public ledger cannot be edited (only added to), and so it is clear to see the history of transactions. The confirmation of these transactions by a network of decentralised computers gives confidence that nothing has been manipulated.

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

A traditional database can be edited retrospectively, and relies on the trust, and service, of one or more parties. These parties can be compromised by conflicting incentives, and are also vulnerable to human error.

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

Digital provenance removes the need for trust and allows independent verification of transactions and history of ownership. Business therefore do not have to rely on their trust of suppliers, banks and service providers, for example, and can also provide more transparency to their customers. Such examples of benefits include real time auditing without having to employ and external account, and confirming the origin and quality of ingredients or materials at each stage of a supply chain.

  1. How does blockchain enable digital provenance?
    You can track and trace everything through the blockchain so the information can be seen, verified and not altered
  2. Why doesn’t a normal database bring the same provenance?
    you don’t have the same visibiity, you are reliant on someone giving you access to the information and you cannot verify it
  3. Why is digital provenance such a great benefit to many businesses?
    You can track and trace it, it cannot be altered so you can trust what you see.

How does blockchain enable digital provenance?

Blockchain is a decentralised / distributed data base onto which records can be added but never removed. This allows for a network of ledgers to verify the legitimacy of each new record.

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

Because a normal data bases are not distributed as blockchains are, thus, prone to being changed / hacked, etc.

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

Because they no longer need to trust their supply chain - they can verify it!

  1. How does blockchain enable digital provenance?

Blockchain only allows you to add data, it cannot be changed or removed. As a public ledger, data can be verified by anyone. All transactions can be traced and tracked.

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

A normal database has the function of being able to add, edit and remove data which would challenge the integrity.

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

It creates a trustless system. It will allow customers to be able to verify objects in products and it also allows businesses to track their supply chain more efficiently.

Blockchain enables digital provenance through creating a trustless networks that verifies all transactions and is immutable. It is a digital stone that can not be changed once written.

A normal database does not bring the same provenance because it is centralized and can be changed by the controlling entity therefore requiring trust in the exchange. Changes and transactions are not verifiable as the decentralized infrastructure needed to do so does not exist.

Digital provenance allows businesses to perform real time and verifiable auditing and supply chain tracking. This allows them to assure every step of their processes and verify their partner’s practices in real time for customers, stakeholders and regulators. Clarity can be achieved in the current workings and profitability of the company on a day to day basis and the need for trust in partnerships is reduced.

  1. Blockchain allows provenance as it only allows the entry of data and not deletion. Every computer connected on the blockchain has a copy of the ledger so all transactions can be verified

  2. Traditional databases can always be manipulated by the creator. On the blockchain, every computer has a copy of the ledger. This requires no trust as all computers/nodes on the network must verify the transaction.

  3. Digital provenance allows business and customers about the integrity of information about supplier information. Every step of the manufacturing process can be hypothetically verified and accounted for.

    A normal database requires periodic audits to verify, transactions may be “opaque” and not transparent, information is vulnerable to corruption
  3. Why is digital provenance such a great benefit to many businesses?
    Able to verify immediately, no need for “trust” and thus not exposed to manipulations, improved service, public confidence in organizations improved, expenses reduced, litigation exposures reduced

  1. How does blockchain enable digital provenance?** Through blockchain technology Provenance can provide real time tracking information/auditing that can be applied across a variety of fields to enable companies and users to trace products and data from their origin.

  2. Why doesn’t a normal database bring the same provenance?** Information is in different layers or locations. For example, an accountant has to work to verify and combine transactions from a bank account, combine with receipts located at a business, trace cash transactions and perhaps checks printed out from another software. Quickbooks accounting software attempts to sync bank transactions into an accounting software except it is not public, transparent and depends on a user to verify and accept the information and half of the transaction have to be manually created therefore it is not up to date information which can lead to user error and manipulation. With provenance data is captured, recorded, tracked, and synced on Blockchain technology in real time and in one place that cannot be changed or manipulated.

  3. Why is digital provenance such a great benefit to many businesses?** Since data is so efficient and provided in realtime, this helps Companies can make better informed decisions and operate more seamlessly. Improves company image as well since product information is transparent and accessible.

  1. The blockchain is like a digital stone, you can write data on it but it cant be removed. this way you can verify digital provenance of everything.

  2. Normal databases are on privates servers you cant verify by yourself if the information is true, you need to trust .

  3. Because everything is wrote on the blockchain, you can track and do real time auditing soo you can remove the trust concept. Dont trust, verify!
