Data can be removed. Less need for Accountants

  1. Blockchain facilitates provenance by recording the ownership and process history of data objects. This data is immutable, and trustless upon addition to the blockchain.

  2. Traditional databases are highly centralized, requiring a trusted third party to maintain the database as well as provide effective and objective governance. This structure creates vulnerabilities which can be exploited by bad actors.

  3. Digital provenance is a huge leap forward for supply chain efficiency and macroeconomic data analysis. It will allow producers, vendors and consumers to communicate more easily and to be more certain about the features of the products in question, such as where the materials come from, where it was assembled, etc.

  1. Every transaction and associated details and from whom to whom (public key to public key) is verifiable to everyone on the network and can be researched by anyone using block explorers.
  2. Normal databases are for the most part centralized and private as opposed to being permissionless and decentralized so in normal databases we have to trust in humans we can not verify.
  3. Digital provenance is a great benefit to businesses because it enables verifiable trust for the consumers using their product, consumers can verify the claims for themselves and that will build confidence and brand loyalty if every claim is verifiable.

How does blockchain enable digital provenance?
Provides a digital immutable ledger that can be verified by all participants

Why doesn’t a normal database bring the same provenance?
Because a normal database can be edited or manipulated

Why is digital provenance such a great benefit to many businesses?
It allows all businesses on a supply chain to verifiable prove where items came from

  1. Is decentralized ledger technology. That enables it to be immutable and available for anyone to audit. Which in turn makes it trustless.

  2. It is centralized. All the information is under the control of the entity using it. There is only as much transparency as the governing body wishes.

  3. They can track inventory among other things in real time. This information is available to both provider and customer which eliminates the need for trust. Don’t trust…verify!

1 By cueing it in stone
2 Beacuse centralized data bases don’t fit trustlessness
3 because consumers can compare the ingredients pre written in stone with the actual goods

  1. every transaction is written on blockchain (and cannot be removed), it can also be easily accessed by the general public so it is transparent

  2. a normal database is centralised by an authority, which means it can be easily changed, erased or added on to

  3. customers can easily verify what materials have been used, allowing businesses to gain their trust and confidence

How does blockchain enable digital provenance?

Digital providance is a part of blockchane identity. The blocks are not editablle or removable. There are added on a open ledger so they can be tracked from everyone who needs the information. Great way to put the obeying trust aside.

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

Becouse normal Database can be edited really easy.

Why is digital provenance such a great benefit to many businesses?
Because it has vast amount of usege.It can be implimented in every single action, sistem and function. All of these can be transperent, traked, and absolutley decentrilized.

  1. How does blockchain enable digital provenance?
    Blockchain allows to track transactions in real time. It is like auditing in real time.

  2. Why doesn’t a normal database bring the same provenance?
    Normal databases can be edited. Blockchain is transparent and you can only add to it, not remove.

  3. Why is digital provenance such a great benefit to many businesses?
    Because you don’t have to trust anyone. Everything on blockchain is verifiable.

  1. It’s a decentralised system built to securely store auditable, unchangeable and transparent information.
  2. Because is centralised and therefore not readily accessible nor reliable.
  3. It increases the trust between organisations and customs by creating and developing transparent businesses models.

  1. Provenance is enabled through a distributed ledger where no information can be altered or erased.
  2. Normal Databases can easiliy be altered by the entity that is supervising it.
  3. Trustlessness makes audits or supply chain mangement quicker, safer and easier to handle

  1. using public ledgers with their content being dependent and immutable connected to previous ledgers and their aggregated content, the blockchain provides a seamless history of every information stored within. Everyone can access the blockchain and trace back and verify the provenance an correctness of the information. The blockchain stores its provenance inside itself.

  2. The data in a normal database is not connected in an immutable aggregated fashion, therefore the provenance of data can be changed without the rest of the databass noticing it.

  3. Businesses can use the digital provenance to garantee the quality and origin of their products. They get insights into how, where and when the resourses and parts were produced or assembled, wich is always a good thing.

  1. Blockchain being the “Digital Stone” on the internet allows for provenance because everything that is done in the blockchain stays in the blockchain and does not allow for transactions or anything else to be removed so everything stays and is always up to date, so you can always see where what you put in goes.

  2. A “normal” database you have to trust what is being said to you is true and hope that is the case. However, that may or may not be true.

  3. people want to know where everything they buy is coming from. Food, Cars, Cloths the brand of the item is just as important as where it came from especially today. this is a great use for business because not only can they prove where the product came from but can avoid questiionalble products on the market.

  1. It enables digital provenance since the blockchain immutable.

  2. In a normal database you can add and remove data, whereas in a blockchain you can only add data.

  3. During a transaction with a client, centralized businesses rely on trust. It can be removed by using a blockchain.

To the question “How does blockchain enable digital provenance?”, many of you said that it is decentralized. Considering that a blockchain can be private. It is centralized and people that controls it can modify it.

Please correct me if I am wrong

  1. Verification (a guarantee of digtal provenance) is achieved via maths (cryptographically provable decentraisation) rather than ‘trusting’ a seperate person or entity.

  2. Normal databases are subject to manipulation and are not trustless and cannot be verified in the same manner as described above. Data can be miss-handled in ‘Silos’ and data can be removed. With Blockchain data cannot cannot be removed… Only added.

  3. For any business seeking to guarantee the quality and/or source / origin of product along the whole supply chain… Blockchain offers the ability to Verify and not rely on trust alone.

  1. Blockchain removes trust from the equation by making all additions to the ledger open to the public, easily verifiable by anyone, and immutable.

  2. A normal database can be modified by a central party. This means that a third party becomes necessary to audit the situation, and confirm that modifications, additions and deletions from the database are legit.

  3. Digital provenance streamlines the auditing process. Businesses will not have to spend the fortunes they are currently spending on hiring auditors. It also makes the business more in line with the trend towards more corporate transparency, eliminating the need for trust.
