1 Blockchain enable digital provenance by providing tracking history via public ledger which cannot be changed as it is a decentralized database.
2 Normal database cannot bring the same provenance as it is centralized. Transaction history can be changed, values can be added or removed by whoever controls the database. It is also much easier to hack a centralized database
3 Digital provenance is such a great benefit to many businesses as it increases transparency and trust . Provides real-time audit capabilities. Reduces costs, it allows verify claims of origin, authenticity and production.

  • How does blockchain enable digital provenance?

Blockchain provides a complete transparency about the origin of transactions. As it is not possible to place fake transactions - the BC will refuse those -, or to change saves transactions, the original information is always available for every member of the BC community.

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

Databases as we know them are single information storage entities controlled by few individuals. Unauthorized changes of information are possible and reality, in fact there is no guaranty for the real provenance of an information in common databases.

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

The basic principle of current business relations is trust. We trust our product builders that the products provided consists of the parts/ingredients the product builders declare. A public available digital provenance information relaxes business relation chips and eliminates surprises.

  1. By making all transactions public in a trustless environment.

  2. Because a normal database is mutable and you can delete and modify data, not only add.

  3. It removes the need of auditing what it’s reported as no information is dark but public.

1 by the fact that no data can be changed

2 because It can be edited

3 because you finally can get into a decentralized, trustless, developed system which finally takes out the few institutions on power and give us the possibility to live equally

Homework on Provenance - Questions

  1. How does blockchain enable digital provenance?

Blockchain provides an immutable database where things can be verified without the need for trust.

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

A normal database is governed by a centralized authority that has the ability to change the information within a database.

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

Businesses through digital provenance can now verify things throughout the supply chain process, This includes things like status, ingredients, as well authenticity.

  1. Since data can only be added, not erased, it is possible to track all transactions in a trustless way since all the computers in the network agree on the tranactions on the ledger/database.

  2. A normal database can be changed at will by the entety controlling the database. You have to trust the part controlling it. Its not trutless, like a blockchain is runing thousands of thousands of computers verifiying the transactions onto the ledger.

  3. Their customers can trust them since everybody can look in their ledger and see for themself. Auditiors have all the information about transactions in real time as soon as its written onto the ledger. And when its on the ledger it can not be changed.

  1. How does blockchain enable digital provenance?
    answer: Blockhain enables digital provenance by its architecture that is based on immutable digital real-time records that is accessible publicly through its nodes

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

answer: Normal database is isolated and cannot be accessible from the public, thus it cannot bring the same provenance as the Blockchain

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

answer: Digital Provenance brings many benefit to many businesses as it provides a trustless transaction since all events are real-time verifiable and does not require a third-party auditing body or authority

  1. How does blockchain enable digital provenance?
  • The verification needed by multiple devices on the network, traceability of transactions, and immutability of data enables digital provenance in the blockchain.
  1. Why doesn’t a normal database bring the same provenance?
  • A normal database would have the capability or function to remove the data from the storage. Also, they are generally centralized and the data can be manipulated.
  1. Why is digital provenance such a great benefit to many businesses?
  • It is of benefit to businesses because of the reduction of cost/fee. The traceability of the transactions. Easier accountability through the transaction itself. Unforgeable data, as the all the device in the network needs to verify the data.

  1. It uses a public ledger which it’s is transparent and can’t be altered. It can give a great amount of data which is verified.
  2. It’s not public and can be altered. You have to trust that the given data is correct.
  3. It doesn’t require trust but it verifies. It can provide a great amount of verified data which will take away auditing and save a lot of time and money.

  1. How does blockchain enable digital provenance?
    Blockchain does not rely on a centralized “trusted” company or person to ensure the information being given is factual or correct, it relies on a digital ledger that can be verified and audited by anyone in order to maintain factual data.
  2. Why doesn’t a normal database bring the same provenance?
    Normal databases rely on a central owned or run system that can be changed or manipulated by any one person with access to change the data, which can lead to inaccuracies based on human error or deceptive practices.
  3. Why is digital provenance such a great benefit to many businesses?
    The need to not rely on the potential inaccuracies in human error or deceptive practices can give companies the peace of mind that data is correct when transferred, given the trustlessness of blockchain. They will be able to VERIFY the data and audit in real time, allowing a trustless system, saving time and money.

  1. Blockchain provides a transparent and immutable method of recording transactions. It removes any guess work or approximations.

  2. A normal database may use alternative methods that are probabilistic in nature and therefore imprecise. They may be corrupt, approximate, or inaccurate and are not reliable.

  3. Digital provenance is great for many businesses because it can remove expensive and cumbersome processes. It is also secure and verifiable which makes it more reliable and providing decision makers with confidence.

  1. Blockchain makes the ledger open to the public and accessible for everyone to see. You can only add data and not remove it.

  2. Normal data is stored on servers that are controlled by an entity. the entity can change the data at will.

  3. It allows business transactions between two parties to be more transparent and more efficient. Everything is traceable and doesn’t have to be based on trust. Eventually, we could reach a point where real-time auditing For companies occurs alongside their transactions that are being made because records are being recorded as transactions are being made and are unable to be changed.

  1. Blockchain provides a platform in which digital provenance can allow entities to use a blockchain to verify and store data in a trust-less manner.

  2. A normal database can be controlled and manipulated by a single entity. Therefore its validity can be put to question

  3. Its a great benefit to business as it can streamline operation and provide a immutable ledger in the case that something needed to be traced or tracked.

  1. Blockchain can be used as ledger to record all transactions, which is created in a decentralised manner with consensus on the validity of the transactions performed by a network of nodes. Once transactions are validated and recorded, they can not be undone. This provides a full audit of transactions, open and publicly available to all.
  2. Traditional databases are centralised and private. They can be manipulated by individuals, companies or governments to suit their own needs.
  3. Digital provenance provides benefit to businesses because it is openly available to all to see. This allows businesses to share details of transactions and allow anyone to track them through time, allowing businesses to build trust with their customers and encouraging all businesses to operate in an honest and open manner.

  1. Acting as a public ledger where all the transactions are tracked in real time.
  2. Above alll because other database are centralised. Blockchain it’s descentralised, can’t be changed it’s information once it’s writed in the database being inmutable and completely transparent for audit.
  3. It’s a big benefit because as public ledger can be used to track any information thant need be tracked or validated. This goes from financial purmpose to logistics, etc…

  1. How does blockchain enable digital provenance?
    Blockchain enables digital provenance by acting as a digital stone in which data can be entered but not removed.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database does not bring the same provenance because in a normal database, data can be added, removed, and overall tampered with. It is not set in stone like it is in the blockchain.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance is such a great benefit to many businesses because record keeping will be made simple. It will be easy to go back and examine and verify all transactions with ease and accuracy.

How does blockchain enable digital provenance?
Public ledger where all the history of transactions ownership are stored and not removed in a decentralized manner.

Why doesn’t a normal database bring the same provenance?
Normal database has to be trusted by database provider. whereas in blockchain, because of decentralized nature. we do not have to trust anyone instead we can simply verify it. It can be verified in trustless manner.

Why is digital provenance such a great benefit to many businesses?
Since the transaction stored in blockchain, it adds trustless transparency. Customers do not have to trust the supplier. In case of real-time auditing, it can save money spent for auditing.
