Homework on Provenance - Questions

Blockchain and Bitcoin 101
#1034

  1. Blockchain enables digital provenance by emplacing immutable transaction on the chain. There is no centralize authority to alter the data or transaction on the chain.

  2. Regular database are control and can be altered or changed at a central point. This data or transaction has to rely on outside auditing and has the issue of trust that the blockchain does not have.

  3. Digital provenance is great for many business because it assist with supply chain tracking. For example if a company wanted to keep track of its ingredients on a product.

  1. How does blockchain enable digital provenance?
    Data entered into the blockchain is permanent and trustless, so a series of events can be traced from the destination to the origin.

  2. Why doesn’t a normal database bring the same provenance?
    A normal database requires an authority to access the data in a centralized location which compromises provenance as the truth can be altered.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital Provenance enables truth efficiently. Practical uses can include the marrying of accounting to transactions so that real-time auditing is a possibility.

How does blockchain enable digital provenance?
Transactions recorded in the blockchain are set in stone and accessible by the public. This means the chain of custody process is permanently recorded and can’t be altered, every steps are logged so are traceable from beginning to end. This allows real time auditing without requiring trust.

Why doesn’t a normal database bring the same provenance?
Regular database have ownerships and are modifiable. Information can be changed, erased, or manipulated therefor there is less accountability. Its centralization makes it more vulnerable to manipulation and hacking.

Why is digital provenance such a great benefit to many businesses?
Because now you can ‘verify’ information for yourself instead of ‘trusting’ words by mouth. Auditing is easier and more efficient as one can access the full records which are recorded in the blockchain, instead of having to ask for permission and given the information by a third party, who can withheld or obfuscate information. Therefore auditing is more efficient and reliable compared to traditional methods. This helps make the production process more transparent, reduces cheating in the supply chain, and promotes better quality control.

  1. Records cannot be erased. It can be checked by anyone. Trustlessness.
  2. They need to trust another party, a central authority.
  3. Real time auditing. Easy to verify business claims.

1.How does blockchain enable digita provenance?
Simply by having an immutable ledger which would be near impossible to be tempered

  1. Why doesn’t a normal database bring the same provenance?
    Normal database requires trust of the owner of the database to be honest without giving the trust-less verification that blockchain provides.

  2. Why is digital provenance such a great benefit to many businesses?
    Blockchain provides real-time auditing of its ledger, reduces the cost of auditing and gives much more reliable source of information for verification purposes.

  1. The blockchain creates a digital record that cannot be changed once it is created therefore a permanent record is created where people anywhere in the world can come look and verify it.

  2. A blockchain provenance cannot be altered therefore making it a trustless system where as the normal database can usually be changed forcing people to trust that the data has not been tampered with.

  3. Making the provenance digital is great because anyone at anytime can go in and verify the data/blockchain creating a trustless system that is easy to audit.

I was explaining provenance today to someone interested in blockchain. I gave the analogy of being in a grocery store, scanning a product QR code(or something like that) with an app and having a networked varification of the products provenance, explaining it in point form or short prose. Imagine we could know a verifiable story of anything with a QR code, including the values, ethics and practices used along of its producions, trasportation and distribution.

  1. The blockchain is local READ only database that create permanent record of all transactions. It can be used to read, verify transactions publicly also known as a “Public Ledger”.
  2. Because all transactions CAN’T be modified thus making it a trustless system.
  3. It benefits are including backup blockchain, auditing, security, etc…

How does blockchain enable digital provenance?
Blockchain technology enables real time auditing and tracking.

Why doesn’t a normal database bring the same provenance?
A normal database may pass through several different systems each with their own form of auditing. Human error can often occur as data is passed from system to system

Why is digital provenance such a great benefit to many businesses?
Accounting and Transaction Layers can baked into one single transaction and be encrypted between users for added security. Removing the need for third party auditors. Commerce items can be traced from origin through any part of the supply chain.

  1. Because blockchain is decentralized and it makes us able to trace all the financial transactions in real time. It is an open source ledger where no data can be manipulated or removed.
  2. Because a normal database isn’t open source and you can remove things, opposed to blockchain database. You also need “trust”.
  3. Because you can thoroughly track what is in the items the company or order, keeping track of eventual manipulation such as child labour, illegal genetic manipulation in food etc. It is also trustless so you don’t have to involve the influence of The Human Factor.
    You can also audit transactions in real time which makes up for great savings in the company as the process is easier, more reliable and more cost-efficient.

  1. Allowing the monitoring and auditing in real time of all operations.

  2. Because in a normal database, you can delete and update the records. Also you have differents profiles, with different access level.

  3. Because it’ll not depend anymore in the trust, and have prove facts of the different actors involved.

  1. Blockchain only allows creation or addition of records. Modifying or removing of information is not possible. So, a verifiable history of any transaction is made possible.

  2. Regular databases allows for creation/addition as well as modification and deletion of data.

  3. Digital provenance provides easy access to history of any transaction all the way back to its origin making auditing simple and accurate.

  1. By providing a system that removes the need for trust. It provides a system of verification.
  2. Blockchain/Ledger cannot be edited, only added to.
  3. See point 1. Actually see points 1 and 2 :slight_smile:

  1. Blockchain enables digital provenance thanks to its decentralized ledger, trust is incorporated into the code itself.
  2. Normal database systems are centralized and as such data can be changed and manipulated by the owner of the system or other partyes that have acess to control the system, blockchain can free us from corruption and stealing
  3. Digital provenance has the ability to speed up many processes in the supply chain and other parts of the business, enforce trust, reduce all types of costs for the company. Overall diminish administrational work so the company can focus more brain power on the production and inovation of its product.

Being an immutable database it blockchain can ensure that data stored are not manipulated by anyone. It will also have transparency which can be trackable on real time by anyone. That is why it is also called public ledger.

Normal data base can be manipulated by the centralised party. For example: facebook is not transparent as we don’t know how the users data is stored and where it is shared, public cannot see in the real time.

It will bring accountability and transparency to the business which will bring trust between customers and business.

  1. Blockchain enables digital provenance because one can add to its database but cannot delete records from there. Blockchain’s public nature enables the traceability. :v:
  2. Other databases typically allow users to add and also delete records. Hence they do not bring the same provenance.
  3. Not to rely on trust but to verify the origin. :handshake:

  1. Blockchain enables digital provenance by allowing financial transactions to be traced, tracked, audited, verified etc. in real time on a public ledger without having to trust any third parties.

  2. A normal database is usually centralised and is therefore not always accessible to the public. For provenance, a certain amount of trust is always involved with third parties who may interact with the centralised database.

  3. The accounting process can be simplified drastically for businesses as transactions may be recorded, verified, audited etc. instantly without involving any third parties. This may save time and money for a business.

1- With a distributed setup, without centralized control, where each node has a full copy of the ledger,
that is used to validate any transaction for correctness before accepting them. Once recorded and validated on the blockchain a transaction can not be changed/removed.
2- A normal database can be changed/manipulated at any time, with the potential to “change” the past records, the provenance is just as big, as your trust in the operator / program.
3- Efficiency & easy of keeping track & proofing something, like “Auditing” of financial records, inventory, sourcing of sub-products, ingredients, etc…

  1. Public ledger, auditable, so you can see where things come from + cannot be changed by participants, so you can trust the history to be true.
  2. A normal database does not include all participants’ history so cannot trace the history of movements
  3. Digital provenance brings trust as people can verify things on the public ledger. It a applices for example to accounting, supply chains in general (clothes, food…) - whereas we use to live in a “trust” way where you could not verify anything and had to trust blindly, now with blockchain you can verify for yourself.
