Homework on Provenance - Questions

Blockchain and Bitcoin 101
#2564

1 - Blockchain enabnles digital provenece by checking the information before it is added with other blocks in the chain, if it is confirmed by others blocks, that information can be added to the blockchain. So if you want to add false information to the blockchain you have to add it at the same time in all the blocks that integrate the blockchain, which is almost impossible.

2 - Normal databases cant bring the same provenance because data can be erased o deleted, which make impossible to trace back information.

3 - Digital provenance with blockchain brings a great benefit because it delete trust factor on the agreements, its allows to do real-time auditing and traceability, in other words its brings transparency.

  1. Blockchain enable digital provenance as data once written or registered, it can’t be altered or modified. Data can only be added as it registered new entries, while referring to the previous block as it verified before it becomes permanent in the chain.

  2. Normal database can’t do the same as data can be easily manipulated or erased. We will need to put all trust to the central body or company that they can governed the database well and safe, and it is owned by them and we will not have the freedom of accessing it anytime.

  3. It is beneficial for businesses as it introduces transparency, real time auditing and tracking. Thus it it brings trust and confidence to the entire chain of stakeholders.

1.Blockchain enables digital provenance because it provides an immutable
digital chain of info and it is real time info.

  1. A normal database is expensive and it is not real time info.

  2. Digital provenance is great for businesses because it can’t be altered which means it is trustless, it is available publically and privately and it is fast.

Homework Answers - Provenance

  1. Blockchain enables you to do auditing of any type of transaction in real time by being able to combine the transaction layer with the account layer and can be verified within minutes. All transactions and processes of any kind can be traced and tracked from the way tax money is spent in government, to ingredients in food, to the process of manufacturing clothing.

  2. In a normal database information/data can be modified, changed and/or deleted which prevents provenance from being able to exist. This isn’t possible in blockchain

  3. It’s a huge benefit because it eliminates the need for trust in any business situation or relationship. Provenance gives business owners the ability to verify every aspect of their transactions and processes.

  1. Blockchain enable digital provenance by shifting away from traditional method of data storage. That blockchain allows new data to be engraved where it can not be edited. Also transactions can be verified from previous blocks without the need of trusting anyone.

  2. In a traditional database, data can be edited or deleted by the owner. That may storage false data leads to inaccuracy.

  3. Digital Provenance benefits many businesses simply due to blockchain’s properties. To be able to verify transactions without a need of trusting anybody by verifying through previous blocks instead.

  1. Digital Provenance is enabled by being able to track and verify each and every transaction.

  2. With a normal database information can be removed and there may not be other cpu/database to keep the database accountable. A normal database does not have trustlessness.

  3. Digital provenance is a great benefit for companies because it allows for them to track ingredients, inventory, or possible inefficiencies in a supply chain.

1- Digital provenance is enabled through blockchain by being trustless and trackable. No longer are we subject to trusting your supplier but being able to track and verify on the blockchain.

2- Because normally the accounting levels and transaction levels are different in normal databases. Which means its harder to verify and more trust is needed.

3-It will be huge for businesses in supply chain no longer do you need to trust where say ingredients come from. You will be able to track and verify it on the blockchain. It opens the doors to much more oversight and accountability.

1.Blockchain is ideal for provenance: What is written can`t be change. All transaction ( materials, ingredients, parts) are traceable.

2.Normal centralized database has few disadvantages. Centre could be attacked or switched off. Someone who has power over database could potentially change ( fake ) records in database. Decentralized ledger has imunitu against this problems.

3.There is no doubt, that digital provenance will find space in many companies. For example in engineering business where I work, we use a lot of paper certificates. Many of these certificates have to be coppied, send with product and stored for many years. Blockchain will save a lot of paper and trees.

1: Blockchain technology enables digital provenance by providing both suppliers and purchasers a more transparent understanding of any information pertaining to those they’d like to do business with. With blockchain technology you are given an entire history of each individual transaction, whether it be ingredients from distribution centers or farms, to safety or insurance measures taken by the company or supplier. Information stored on the blockchain in un-editable thus safeguarding against potential dishonest partners or hackers.

  1. A normal database does not provide the same provenance because standard databases are centralized and subject to the whims of whoever is admining or running the database. This allows potential cases of fraud, editing information or erasing it entirely while also providing close to zero transparency for outside viewers, as any information that the database holder doesn’t want you to see can easily be omitted.

  2. Digital provenance not only negates the need for trust amongst purchasers and suppliers but also allows potential suppliers/purchasers to validate or disregard any questions or concerns they may have regarding the companies supply chain by scanning through the information provided by the blockchain. Time is money and this will allow both parties to see greater levels cooperation without trust required while saving time.

  1. Everything is recorded on a public ledger. Everyone can see it, therefor it brings full transparency.
  2. Normal databases can have their information changed or deleted. Blockchain cannot have it’s information removed. It’s there forever.
  3. Digital provenance creates trust in the business world. It’s mathematically verified, therefor it can be trusted.

  1. How does blockchain enable digital provenance?

    A. Blockchain enables the usage of a digital history of transactions to the very based of its origin.
    Everything is stored in a blockchain data and making such information public and accessible; as well as making it impossible for data to be changed.

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

    A. A normal database can be vulnerable to such attacks, defects, hacks, etc. Data can be defected, damaged, or destroyed and such information will be gone and impossible to trace back.

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

    A. Imo, it provides a more lucrative way for customers to interact and verify sources of such transactions.

  • How does blockchain enable digital provenance?
    Firstly, every transaction recorded can not be modified (stone carving example!) and second there are as many copies out there as there are nodes (if this is not true, I have something misunderstood…), so it is practical indestructible. If one copy gets lost, there are countless more out there. oh, and it is open to read for everyone, therefore we have full transparency.

  • Why doesn’t a normal database bring the same provenance?
    A normal database is not based on blockchain: therefore it can be modified and usually it is centralised. Due to centralisation, it is not transparent for everyone: There are always some who are “more equal than others” to read and write.

  • Why is digital provenance such a great benefit to many businesses?
    A lot of money spent for auditing can be saved, which also means that a certification process is getting easier and much cheaper. And certification is everything when it comes to product quality and safety. There is no need to trust anymore because everything is verified by the blockchain.

  1. The blockchain enables digital provenance because it is a ledger of all the bitcoin transactions since the beginning of bitcoin. We have access to the complete timeline and history of each bitcoin created and each transaction ever made. So if we take a specific transaction we can tell where the funds came from prior to that transaction, thus linking each transaction to one another up to the transaction #1 on the ledger. In other words, all the transactions are linked to one another like a chain of events up to the beginning of of the ledger thus providing provenance. The integrity of the chain of provenance is enforced and maintained by the fact that the ledger in distributed over a network of nodes that must verify each entry before it’s approved to be added to the blockchain.

  2. With the bitcoin blockchain, because the other nodes are validating new entries, we know that the ledger is true and accurate. In a normal database we can alter the ledger with no safety mechanism to ensure it’s integrity (especially if it’s centralized at only one place).

  3. Because there is no more need for trust between parties since the provenance from the blockchain makes it irrelevant. It makes transactions and processes more open and less opaque.

  1. How does blockchain enable digital provenance?
    The blockchain enables a trust-less process that provides a user with the ability to check any ledgers for any information they would want. This process of verification creates a fair playing field for all users without the threat of manipulation by bad actors who may want to travel in the darkness and stay out of site.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database is centralised and the owner has the option to retroactively change transactions at will.

  3. Why is digital provenance such a great benefit to many businesses?
    It creates a level playing field and helps small business get out of the sludge of manual transactions which are slow and takes man power. Digital provenance can automate and verify all transactions through the blockchain without needing to go over everything bit by bit, connecting accounting with transactions

1 - Because it is trustless and does not require a 3rd party validator/intermediary. This is as a resuld of it’s decentralized ledger based on multiple nodes.
2 - Because it is not decentralized and requires a 3rd party validator, and is also not immutable.
3 - Because it is fully transparent and can be audited in real time, and is also trustless

  1. Through a public ledger where anyone can verify the latest transactions on the network.
  2. Because it is centralized versus being decentralized, information could be removed. On the blockchain no transaction can be removed only added.
  3. It allows them to verify all transactions on the blockchain without trust issues. For instance track the provenance of food , chemicals, spare parts etc…

  1. Blockchain is an immutable database. It allows for information to be entered and permanently sealed for posterity.
  2. A normal database can be edited and doesn’t provide the quality of immutability.
  3. Blockchains provide a trustlessness that will change everything we know about commerce, government, record keeping, and money.

Blockchain enables digital provenance by having a copy of itself on every node that acts as a public database of each transaction.

I guess a normal database doesn’t have the same provenance because you can take information out of other databases but Blockchain you cannot.

Because it makes it verifiable or trustless.
