Homework on Provenance - Questions

Blockchain and Bitcoin 101
#1115

  1. Blockchain databases only permit the addition and viewing of transaction records to the ledger. It is not possible to update or delete these records. As a result, once a transaction is recorded, it will not change, thus making for a useful audit trail and by extension enabling provenance

  2. A normal relational database allows for the update and deletion of records as well as the creation and viewing and so is vulnerable to tampering. This makes it a poor candidate for provenance

  3. With digital provenance, businesses can have information easily audited and/or verified. This has the effect of quickly facilitating the credibility of a business in the eyes of customers, auditors and the government for tax purposes.

#1116
  1. Blockchain enables digital provenance by combining the auditing layer with the transaction layer. Every transaction is recorded and cannot be removed. Every transaction is also open for anyone in the world to view this digital “stone ledger”
  2. A normal data base does not provide the same provenance because most data bases are not both open source and immutable. This means data can more easily be removed or hidden if the central authority wants it to be.
  3. While companies that preform financial audits won’t be too happy, many other businesses will greatly benefit from blockchain. It will create trustless-ness in supply chains and give businesses more information about the origin and status of products and materials.

  1. How does block-chain enable digital provenance?
    Via algorithmic hashing the block-chain is able to store data and encrypt it to make it a immutable. This takes trust out of the equation especially given it’s public nature.

  2. Why doesn’t a normal database bring the same provenance?
    It can be changed or edited unlike a block-chain, and a normal database can be made private so that only a specific group or one person can view the data base.

  3. Why is digital provenance such a great benefit to many businesses?
    A middle man or entity such as a bank can be removed from the equation, thus saving money and possible liability depending on how the block-chain is utilized by the business.

  1. Blockchain enables digital provenance through the use of a network of decentralized nodes that ensure the digital ledger has not been compromised because all transactions need to be verified by the nodes.
  2. A normal database does not bring the same provenance because normal databases are generally centralized and records are not verified on a decentralized network like blockchain is.
  3. Digital provenance is such a great benefit to many businesses because blockchain’s decentralized nature allows for more transparency and security.
#1119

  1. because all tx can be traced and tracked.

  2. because it is centralized.

  3. It is beneficial in many supply chain type cases because one does not need to trust the individual or supplier/system but instead trust the math.

#1120
  1. Blockchain enables digital provenance because for example the supplier can put information on the blockchain with regard to who he sent his supply of x product and then if the distributor says then recived a different product it can be instantly checked.
  2. a normal database has a single point of failure and can be changed by one bad actor, blockchain does not have a single point of failure because the ledger is distributed on different nodes and checks the ledgers for consensus.
  3. it is beneficial to businesses because it is an added peace of mind knowing that product information can not be tampered with and also be verified on the network with less of a chance of falsification.
#1121
  1. a public ledger can track transactions of ingredients from source to final product, just like tracking transactions of bitcoin from source (miner) to final product (current coin owner)
  2. a normal database is centralized meaning power to corrupt the database is concentrated in a smaller number of individuals, increasing temptation to corrupt the signal (like the one ring in LOTR)
  3. all else being equal, a consumer would prefer less uncertainty about what they ingest
#1122 
        How does blockchain enable digital provenance?
            A blockchain enables digital provenance, by being a live public ledger with a 
            complete history of all transactions. So all transactions are auditable by anyone in real time.


        Why doesn’t a normal database bring the same provenance?
            A normal database is centrally controled and can be manipulated by a private/centralized party.

        Why is digital provenance such a great benefit to many businesses?
            Digital provenance can create an environent of trustlessness. So math is all the is required 
            in order to trust a 3rd party.

  1. How does blockchain enable digital provenance?
    Blockchain is a database, a digital ledger, where data can be added but not removed. And it’s public, therefore it is decentralized So everybody can trace back the origin of every transaction.

  2. Why doesn’t a normal database bring the same provenance?
    In a normal database data can be added and removed. And it is most of the time centralized. This means that using this database is based on trust. Tracing back the origins of the data is difficult and because it is centralized, it is possible you don’t even have access. That makes it very opaque.

  3. Why is digital provenance such a great benefit to many businesses?
    Digital provenance means, in the relationship between a business and his client, trust is not relevant anymore; every step in the proces can be verified. A more direct relationship is possible with less middlemen.This auditing of data is possible in real time, so that also saves a lot of time.

How does blockchain enable digital provenance?

Digital provenance is enabled because blockchain is a decentralized public ledger where all transactions are available to all and cant be change or deleted.

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

because transactions on a regular database can be modified or erased.

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

because all information is verified, every transaction can be tracked and audited in realtime.

  1. How does blockchain enable digital provenance? -OPEN LEDGER
  2. Why doesn’t a normal database bring the same provenance? -CENTRALIZED
  3. Why is digital provenance such a great benefit to many businesses? -TRUSTLESS
#1126

  1. All transaction has been proven and authorized by the network, a false operation can not be added to the ledger. The system is public, and nobody can control and able to change it for his interest

  2. A traditional database is centralized.Info(data)can be added and deleted =not trustful and easy can be manipulated for different goals. Regular databases dot need any authorization
    Blockchain -once added can not be deleted=frustful

  3. Systems can be more efficient. Tracking for goods and transactions can be optimized.

  • How does blockchain enable digital provenance?

Blockchain is a digital data structure where one can only add but not remove data. The data is held on public ledger and can easily be seen and verified by the public. This property of blockchain enables provenance.

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

A normal database can be altered and requires trust, hence it can’t bring the same provenance.

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

Digital provenance allows many business to audit, track data and verify at their will without a central authority and or the need for trust. This makes digital provenance such a competitive edge for business and brings great benefits such as trust-less business.

#1128
  1. All transactions are set in stone, and can be verified any time instantly.
    2.It is allot harder to verify everything in a normal database and will require trusting someone.
    3.Because it makes the whole process much easier and can give a business more trust.
#1129

  1. Storing data on blockchain opens the door for transparency, security, immutability and trustless connection. [Don’t Trust. Verify.]
    What that means is that at any moment we can check the origin of every transaction or network connection between all the suppliers and in that way validate the authenticity of their business.

  2. Normal database lacks transparency among other things. That gives businesses too much control over data or information that they are going to provide us.
    Normal database is not audit friendly for it’s users as it doesn’t give us a quick and simple way to verify the accuracy of information that is provided to us.

  3. There are many advantages for businesses to put their data on the blockchain network, like provenance that enables them to have more trustworthy relationships with their clients, more secure network and the most important things right now is, that it brings adaptation of blockchain technology so much closer to everyday people and serves as a segue way into blochchain world and introduces them to crypto and all it’s capabilities.

1. How does blockchain enable digital provenance?
By making sure that each of the data entered is verified (consensus) and cannot be removed once entered. Also, the data is open for everyone to see or track, except if the blockchain is private, where only specific people have access to them.

2. Why doesn’t a normal database bring the same provenance?
Normal databases are centralised, therefore most of the times, the data that exist inside of them are private. Furthermore, data inside such kind of databases can easily be altered.

3. Why is digital provenance such a great benefit to many businesses?
Because by having an open ledger for your products for anyone to get real-time information on at any time, can be reassuring to the client that what the business is selling is indeed legitimate.

  1. Blockchain is a group of digital stones in a public ledger completely decentralized linked through a network. Its behavior allows to add information but not remove or duplicate. Based on that, it keeps the history of all the information related to the chain of that particular subject.
    Each block could be easily verified in real time.
  2. Normal Data based are normally owned by third parties-companies, with their own interested and following governments centralized regulations. The information could be modified/deleted and many of those companies use different platforms making difficult to integrate data.
  3. We are moving from the “Trust Era” to the “Verify Era”. Since Blockchain is a public ledger with decentralized data, it allows many businesses to complete understand the history of transactions, products, ID and etc. For example, we could have a single Social ID with all the most important information WE WOULD LIKE TO SHARE, such as education, health history, travel history, world single tax return.
    Companies would be able to understand the history of products they are actually receiving (ie: NON GMO) and provide more transparency to the customers. Also, since, data would be more integrated, customers behavior analysis will be easier to study.
    At the moment we are dealing with COVID-19 pandemic, if we had the Blockchain system uprunning worldwide, the data analytics could be more easily assessed, and we might could have found better results.

1.) it is not possible to alter data
2.) data can be altered and manipulated
3.) it enhances trust into data

  1. The blockchain allows the tracking of custodianship and supply chains from
    beginning to end. The blockchain technology enables secure traceability of
    certifications and other salient information in supply chains. Provenance
    enables every physical product to come with a digital ‘passport’ that proves
    authenticity.
  2. Databases have admins & centralized control Only entities with rights can
    access database. No history of records & ownership of digital records on databases.
    Anyone with right proof of work can write on the blockchain. History of records &
    ownership of digital records stored on blockchain.
    3.Digital provenance acts a trustless ledger that provides complete tracbility and
    real-time data and traceability to customers and suppliers.

  1. By allowing us to track supply chain processes with an open public ledger that can only have information added to it and not taken away from it (immutability), this provides us with a verifiable way of tracing things that eliminates the need for trust.

  2. A normal database has a discord between the transactional layer and the accounting layer, it is inefficient, involves the trust of centralised authority, can be hacked or tampered with and is only stored in one place and not on multiple networks or nodes.

  3. It improves efficiency, holds businesses and suppliers accountable, real time auditing, allows for a digital passport to be created that tracks every stage of a products journey to the shelf which in turn allows customers to make informed purchasing decisions.
