Homework on Provenance - Questions

Blockchain and Bitcoin 101

  1. How does blockchain enable digital provenance?

a) Transactions are written to a ledger. Prior transactions of the ledger are “locked” on the chain. All transactions can be tracked back to an account and verified (audited).

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

a) Databases, by default, do not track historical data (changes) only current data. Blockchain keeps historical transitions onchain and therefore retains a “chain” of custody (“provenance”). Additionally, blocks in the chain are built based on prior blocks making it difficult / impossible to change historical information, normal relational databases keep sequential data (like a bank account over period of time) in history of transactions, but it is technically possible to modify these historical transactions (just rows in a database).

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

a) The ability to track and or audit a transaction in real time. Any good or service that is a combination of other goods or services could use blockchain to track the process (series of transactions) back to specific events or companies.

1 blockchain provides complete transactional transparency. requires multiple validations

2 current system relies on trust. invoices, transaction histories on separate ledgers…sketchy.

3 digital provenance is trust-less, only verify. all transactional information in one verifiable cant be duplicated.

Blockchain enable digital provenance by letting the world see each transaction from start to finish. Without a middleman, it makes the process trustless and non manipulative.

The normal datababase doesn’t bring the same provenance because their transactions and ledgers are separate instead of together.

Digital provenance is great benefit for businesses because they will be able to track where their products came from. From farm to fork, the restaurants, grocery stores, and the consumer will know where their products came.

 1.How does blockchain enable digital provenance?

Blockchain is a network of computers where all the data can be add and stock on the letger but never removed. All the data can be verified by using mate which remove the trust less.

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

The traditional data base does not keep a record of the old information and can be modified anytime.

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

because is fast , trust less, easy to verifier, tracked on blockchain

  1. Via a Network of Computers, that verify information that has been put into the database.
    Since the data is immutable, and cannot be removed, it is always traceable.

  2. Because in a a regular Database, you have the opportunity to remove data. You have centralized points of power that can alter or manipulate data ( admins, database operator ). Also the blockchain instantly provides information from a single source wich used to be seperated by different departements.

  3. It completely eliminates trust from the equation. In business you need trustful partners in order to guarantee a good product to your customers. With Blockchain you can simply verify all the variables instead of trusting your business partners. Blockchain swaps out trust for verification and therefore keeps everyone accountable.

  1. How does blockchain enable digital provenance?
    By acting as a digital public ledger where all transactions can be verify in real time auditing.

  2. Why doesn’t a normal database bring the same provenance?
    Because a normal database is mutable. Transactions can be changed.

  3. Why is digital provenance such a great benefit to many businesses?
    Because it will allow them to remove trust and instead be able to verify all information in a secured and fast way. For example, all transactions recorded in a database can’t be removed, so transparency is ensured between partners.

  1. Blockchain enable digital provenance by keeping permanent record of all the transactions. This informations are immutable and can be only added.
  2. A normal database is centralized so it can be changed easily.
  3. The supply chain can help businesses to track informations removing trust in third parties.

  1. How does blockchain enable digital provenance? ( Blockchain is like a digital stone that is written on and never can be erased.)
  2. Why doesn’t a normal database bring the same provenance? ( Normal datbase can be centralised and often owned my a third parties)
  3. Why is digital provenance such a great benefit to many businesses? ( Digital provenance would allow businesses to cut the costs by increasing the effinciency with real-time audits don digitally. )

  1. Blockchain enables digital provenance by providing a means for real time auditing.

  2. A normal database does not bring the same provenance because they are centralized and not transparent.

  3. Digital provenance is a great benefit for businesses because it takes away the need for trust.

  1. Blockchain enables digital provenance by verifying and recording data on database.

  2. It would more difficult for a normal database to achieve the same provenance because, t is centralized and data is usually entered manually and could be tampered with by someone or manipulated at any time during the life cycle of an object.

  3. Digital provenance is great a benefit to many businesses because it helps create a trust-less system.

  1. Blockchain enables digital provenance by producing an immutable ledger that allows the content of the ledger to be tracked and traced.

  2. Normal databases can’t bring the same provenance because they are open to compromises, can be changed and edited without the consumers knowledge and are controlled by a centralized figure.

  3. Depending on the business digital provenance can very helpful. Digital provenance would allow companies to accurately source their products and bring accurate information to their consumers.

  • How does blockchain enable digital provenance?

Blockchain has a real time trace/real time recording of each transaction

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

Normal database relies heavily on trust and can easily translated incorrectly or corrupted

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

It is a great benefit because it takes away the trust and also has public access and private acess and is faster

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

By creating a record in an only-add/no-removal decentralized public database.

A normal database is usually centrally administered and can be modified.

It creates a way to impeccably verify the data in stead of just trusting the data.

  1. Because everything can be verified through blockchain, thus removing trust
  2. Because a centralised database can be manipulated, whereas blockchain removes trust
  3. It is in my opinion mostly a. benefit to the consumers, but business who can keep their consumers happy will thrive, so it’s good for those who embrace it

  1. All the previous transactions are permanently stored on the block chain ledger, entries can only be added not modified or deleted.
    2.In a normal database entries can be added, modified or deleted.
    3.It removes the need for trust, rather data can be verified.

  1. It’s like the common knowledge of a small community (like a village) about who owns what in that community. The underlying data is held by multiple entities, hence cannot be altered by one single actor.
  2. Because it is owned and maintained by a single entity, hence it’s not trustless.
  3. It can hugely reduce the need for the administrative burden that currently exist in order to be able to run our society. There is a good chance that finance and legal will be revolutionized in the next 1-2 decades by blockchain.

  1. Blockchain enables provenance by its immutable characteristic: nothing can be added or removed once it has been verified and a consensus between networks has deemed it correct mathematically.

  2. Normal databases rely on trust of a centralized authority that has the ability to change the data or manipulate it thereby corrupting the information or currency. It is also slow and inefficient.

  3. Digital provenance is a great benefit because it eliminates trust. You don’t have to rely on the word of a company. Information can be verified quickly and efficiently. Audits may be eliminated and companies that are not corrupt can rely on this technology to make them very credible to work with.

  1. How does blockchain enable digital provenance?
  • Blockchain is the framework or system which allows digital provenance to track/audit/and verify a process. It creates a trust-less state, fully transparent.
  1. Why doesn’t a normal database bring the same provenance?
  • They are not decentralized, are not verified immediately, information can be changed and usually do not consist of multiple ledgers
  1. Why is digital provenance such a great benefit to many businesses?
    -Takes a company away from a “Trust” state to a “Trust-less” state, transactions are verifiable and transparent.

1.- All transactions can be trace. Nothing can be erase.
2.- The information is open/available and it accessible in real time.
3.- Take the opaque and the trust component from the transaction and add a constant verification, giving a higher transparency.
