  1. Blockchain technology enable digital providence due to the data trail of all transactions being transparent and available to everyone.

  2. Data in a normal database are subject to change, therefore not trustworthy.

  3. One of the biggest benefits of digital provenance to business is the increased time efficiency and cost reduction (e.q. no need to hire an accounting firm to perform an audit trail).

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?
    Blockchain is a public ledger of transactions. This way everyone can look at all of the records in the ledger and verify that they were actually made.
  2. Why doesn’t a normal database bring the same provenance?
    A normal database has some restrictions onto how anyone can access information and has a centralized owner that eventually could make changes.
  3. Why is digital provenance such a great benefit to many businesses?
    [/quote] It allows trustlessness, and therefore eliminates the need of trust from the system.

  1. How does blockhacin enable digital provenance?
    With decentralization of the list of transactions. Everything is public and easily to verify.
  2. Why doesn’t a normal database bring the same provenance?
    It’s a closed centralized database which is easily manipulated and also has high risk of error included. You can change the data inside.
  3. Why is digital provenance cush a great benefit to many businesses?
    Trust is the issue here… With trust the business is easier you can provide more of your valuable time to other things which provide more added value and not lose your time on trust and verification of other partners.

  1. The blockchain provides “real time” auditing of financial transactions.
  2. Normal databases are not connected to the other computers on the blockchain and cannot verify all transactions.
  3. Digital provenance provides real time auditing and will reduce the costs of auditing and accounting for businesses.

  1. How does blockchain enable digital provenance?
    By providing a database where records can be added to but existing records can never be changed or deleted. Blockchains are usually public and distributed making it easy to verify that there is no tampering. Adding new records usually involves some kind of cryptographic signing. These things combined make it possible to crate fully traceable trust-less records.

  2. Why doesn’t a normal database bring the same provenance?
    Most databases allow editing of existing data so records history can changed. Most normal databases are not practical to run in a publicly distributed manner, so a lot more trust is required. Most normal databases don’t have cryptographic signing of new records.

  3. Why is digital provenance such a great benefit to many businesses?
    Auditing is simpler with a full history that is always accessible and never changing. Does not require direct trust when things are distributed and verifiable.

  1. The blockchain enables digital provenance by recording and tracking all of the transactions in a decentralized manner, in which no central authority or person can change was has been “written on the Viking stone.”

  2. A normal database would be administered or controlled by a central authority or a central administrator that could amend or alter past transactions on the database. The blockchain solves the problem of fudging or cheating.

  3. Digital provenance is great for businesses to ensure that the products and services they provide to their customers are a true reflection of what they are providing. For example, a restaurant may want to ensure that they are getting real lobster from a certain location, or that the packaged goods they receive contain the correct ingredients.

How does blockchain enable digital provenance?

A blockchain is a public ledger where every transaction is recorded since its inception and data can only be added, so data cannot be deleted or changed. Since there is no central organization, but the whole process takes place over a huge computer network, in which each computer (node) has a copy of the original ledger and thus checks the validity of the current transaction in real time, so that each new transaction is checked and if approved only then can be added as new data on the blockchain. That way we no longer have to trust the data, we know it is true.

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

Normal databases are centralized owned by some government agency or company or other entity and no one can guarantee that this data is true because it can be duplicated, deleted, altered, depending on owner or employee preferences. These data centers are usually in a specific physical location, divided into silos that cannot communicate with each other or in the cloud, they are taken care of by an administrator and are usually not available to the public without the approval of the central authority.

Why is digital provenance so great a benefit for so many companies?

Since blockchain is a decentralized technology and every data entered is audited in real time, we no longer have to rely on trust. This, for example, brings food producers accurate information about the origin of raw materials, cultivation, and composition. Food producers most often trust their suppliers that the raw material is as suppliers declare it, especially when it arrives from the other side of the world.
Then they can add information about the preparation and processing of ingredients and the entire supply chain until the moment of purchase of the finished product is recorded on blockchain. Everything is transparent, clear and verified.

1. How does blockchain enable digital provenance? Blockchain enables digital providence through immutability and transparency. Being decentralized guarantees no alteration and/or intervention from any central body.

2. Why doesn’t a normal database bring the same provenance? Being largely controlled by entities means a system based on centralized control and a system that relies largely on trust.

3. Why is digital provenance such a great benefit to many businesses? It allows for users to know exactly what is in their good, what it’s made from and the conditions it has been kept it, just as an example. Consumers also get a peace of mind that their good is not a counterfeit replica of a product.

  1. Information is “set in stone” with block chain technology. That makes all information added to it accessible and transparent.
  2. With a normal database, it is often not possible to access information and transaction history due to tampering or lost data because one person or organization holds the keys to that information.
  3. Removing trust from the equation is very appealing and gives one piece of mind not having to rely on the organisation or individual. These days consumers are interested in the origin of products for health and sustainability reasons.

  1. blockchain gives transparency, security and in depth detail of each trail a certain action/transaction that is made

  2. a normal database isn’t able to guarantee any foul play or incorrect info to be written and read.

  3. it gives users the experience of not needing to worry as everything is set in stone and can’t be wronged

  1. The Blockchain enables digital Provenance by keeping Trac of all Transactions and by verifying the transactions.
  2. In a normal Database, that is mostly centralized, Data can be added and removed or even manipulated. In a Blochchain, Data can only be added.
  3. It is a great Benefit to the Buissineses, becauseof the verifying Process they dont have to trust other Parties, because it is verifyed.

  1. By creating a public, verifyable ledger to view all transactions through
  2. Normal databases are controlled by people that can change or manipulate them. Since they aren’t public, we can’t see them to verify ourselves, so we have to trust someone.
  3. Because it creates a public, trustless ledger that is publicly auditable.

  1. How does blockchain enable digital provenance?
    Transactional activity is recorded forever in the blockchain. The example of the imutibility of a viking runestone is a good one. Activity is recorded in the blockchain, can be added to but not subtracted from. It is held within the distributed ledger among so many nodes verifying and confirming the accuracy. It is trustless.
  2. Why doesn’t a normal database bring the same provenance?
    Our traditional databases are owned by someone, a person, corporation or government entity. These entities are subject to corruption as are the data contained within and can be compromised intentionally or inadvertently. Auditing is necessary to ensure accuracy, trust is necessary and is sometimes not deserved.
  3. Why is digital provenance such a great benefit to many businesses?
    A blockchain enables digital provenance with the capacity of adding a digital blueprint on every physical product that proves its authenticity and origin, creating a public, auditable and immutable record of the journey behind all physical goods.

  1. Blockchain provides the technology required for an immutable ledger to feasibly exist. Negative emotion and human error in transactions will be completely overridden by the cold undeniable data recorded within the blockchain. There is no room for plagiarism or any dishonesty of any kind

  2. Regular databases do not have the security made possible through hash algorithms, consensus algorithms, proofs of work/stake meaning the owner of the centralized database can manipulate data in a limitless number of possible ways.

  3. Completely removes the necessity for trust. In a blockchain there is no need to trust anyone, simply verify if their claims are true or not

  1. Blockchain is an immutable database that can be audited in real time; trust is eliminated with the use of blockchain as everything can be tracked digitally.

  2. A normal database is not immutable; trust is required at some point, thus no provenance.

3.Digital provenance provides real time digital auditing; no physical in-office auditor required.

  1. How does blockchain enable digital provenance?
    You can only add data to the blockchain. You can not remove or alter existing data. If you try to add fake data it will not be verified. The blockchain acts as a public ledger that everyone can look at.

  2. Why doesn’t a normal database bring the same provenance?
    The data in a normal database can be removed, altered and possibly fraudulent. It is usually not public, so only the owner of the database might be able to look at the data.

  3. Why is digital provenance such a great benefit to many businesses?
    Auditing can be done in real time. Instead of relying on trusting other parties, information can be easily verified. The origin of materials and ingredients can be traced.

Blockchain provides a digital public ledger where data or transactions can be securely recorded and distributed in chronological order.

There is no way to be certain that information on a normal database has been ordered correctly and remains unaltered. Once information is recorded on the blockchain it can’t be changed.

Digital provenance provides the ability to record, track and communicate multiple aspects of a business in a way that is completely trustless and therefore transparent and free of human error or bias. Any business that can utilize this potentially saves money, time and labor.
