Homework on Provenance - Questions

[monymike]

HI Mauro,

It is open source so anyone can see the steps from start to end

and the info in the blocks are immutable once on the blockchain.which only goes in one direction.

Does this answer it, Mauro,

thanks

1. Because the blockchain is not owned by anyone.

2. A normal database is owned by someone, which means someone has control over the database which is not the case in the blockchain.

3. It will solve the trust problem, it is a lot safer and transparent.

1. How does blockchain enable digital provenance?

Provenance mean trackable.Blockchain is a database itself that only save information in a public ledger. This information cannot be remove and is public for everyone. This mean that everyone can own and read this database to keep track of all transactions since the beginning of the creation.

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

Normal databases normally are able remove, delete or modify data. Because this fact, normal databases cannot bring provenance.

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

By adding provenance to databases, allow business and normal people to remove third party services or accounting, because provenance allow individuals to do it by their self and even automatic.

1. How does blockchain enable digital provenance? Because you have
   a distributed digital ledger which tracks every transaction. And
   this digital ledger is write-only - so it can not be erased or
   modified once it has been written.

2. Why doesn’t a normal database bring the same provenance? Because
   normal databases are not redundant (there is one copy) and they
   allow read, write, modify, and delete operations. The blockchain
   is restricted to be write-only - once something is written,
   it is immutable and cannot be modified or deleted.

3. Why is digital provenance such a great benefit
   to many businesses? Because monetary transactions need to
   be audited for accounting purposes as part of creating profit
   and loss summations. This audit trail is inherently built
   into the blockchain database already so there is no third
   party information required to audit a blockchain transaction like
   traditional monetary transfers using banks would require.

1. Blockchain enables digital provenance by the transparency of realtime audited tracking of financial transactions.
2. It is not a real time transaction and therefore can be manipulated or facts omitted. It’s not transparent.
3. Allows for tracking and recording of info real time, which is encrypted. It eliminates the trust issue of suppliers as everything is 100% verifiable. Accounting processes trimmed with real time auditing. Can track status of shipments and products condition.

[Crista]

1. Blockchain enables digital provenance because as a database it allows transactions and information to be tracked and accessible by any computer on its network.

2. A normal database doesn’t bring the same provenance if it isn’t decentralised. Without each computer on the database acting as a ledger and receiving its own copy of transactions, the information in the database can be distorted. Information could also potentially be removed or altered in a system without provenance, unlike in blockchain where information can be added but not erased.

3. Provenance is a great benefit to many businesses because its records provide real time auditing for the business, as well as verifiable information about the business’ previous actions. It allows the record of information about the business to speak for itself, and it removes the issue of trust that the business might otherwise have with suppliers, for example.

[Mroman]

1. Blockchain only add information, therefore existing data is inmutable can´t be removed or modified. It provides an unique verification system, with traceability.
2. Normal database can be manipulated, erased, remove, modified
3. Business can verify in a more efficient manner, for instance the audit of the company can be done in a more automatic way instead of checking all the bills. Accounting and audit should be running in the blockchain, most of the frauds in accounting is done by manipulation.

• How does blockchain enable digital provenance?

Provenance is achieved by making the ledger decentralized and removing third party trust

@ivan

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

A normal database is centralized and can be manipulated or lost of data. This requires trust in third party database.

@ivan

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

Because digital provenance is a verified base rather than a trust aspect. Also improves in traceability, real time data and manipulation proof

[Macmillen1]

1. Blockchain enables provenance by creating a transparent and permanent trail of transactions that can be referred to and traced.

2. A normal database can be edited and content removed. This means that you cant verify with certainty that what information is stored on it is accurate, and you are forced to trust it.

3. Digital Provenance is good for businesses because they can ensure and verify that transactional data is accurate by tracing the blockhain and seeing all the steps along the way match up to what the business is being told. This will cut down on things like fraud and deceit.

Homework on Provenance - Questions

• How does blockchain enable digital provenance?

  • Blockchain allows real time auditing and tracking of transactions.

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

  • Normal databases usually do not combine the accounting and transaction layers of auditing.

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

  • Digital provenance can assist in quality control and provide transparency to customers. You can verify using math rather than trusting people or organizations.
  • Financing can benefit by not having the need for people to verify transactions. Supply chains can benefit from this ability to track all aspects of the operation.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?
   Provides a public ledger that is immutable and trustless. It tracks and validates all transactions.

2. Why doesn’t a normal database bring the same provenance?
   Any other database is centralized and controlled by the owner of the database. They may add or delete transactions if they chose to.

3. Why is digital provenance such a great benefit to many businesses?
   It facilitates auditing and provides full transparency.

[Evelys_Diaz]

1. Because blockchain can not be edit or undone, (i.e. It’s transactions are immutable) and it is verifiable.
2. It can be edited, erased, tampered or changed and therefore not immutable and unverifiable if it is broken, etc.
3. It provides a means of tracking, confirmation, history, and does not rely on Trust but Verification of a record that is immutable. This equals security in the validation of the transactions whether it be financial or product and services.

How does blockchain enable digital provenance

• Blockchain does enable provenance by keeping track and tracing transactions in realtime, more like real-time auditing
• It is for securely storing information which is auditable, unchangeable and open
• It also also enables block chain transactions to be trustable and transparent

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

• Provenance allows only one entry for transactions where you can only add things and not remove things, unlike a database, you can perform all the CRUD operations(Create, Read, Update and Delete).

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

• Provenance enables every physical product to come with a digital ‘passport’ that proves authenticity (Is this product what it claims to be?) and origin (Where does this product come from?)
• creating an auditable record of the journey behind all physical products

[Ziheng]

1. Data can only be added to and not removed from blockchain, hence this prevents the modification of the data which most centralised governments do.
2. Blockchain is decentralised, thus there is no way of manipulating the information online by targeting a single source.
3. It allows real time auditing and tracing to take place, hence customers are able to verify the businesses and this will strengthen the legitimacy of good companies.

[Ziheng]

great points Blessing!

[Bouf]

1. Blockchain enables digital provenance by verifying and therefore proving every step of the evolution of it’s database. This is possible because no information can be deleted from the blockchain.

2. A normal database cannot achieve the same provenance as it is only a database and therefore they require human auditors which leaves room for human error. Or you have to trust that the auditors are doing a god job.

3. Because audits become obsolete as it can be done in real time or almost in real time and with certainty that no errors have been made during the process of acquiring this information.

Homework on Provenance - Questions

1. How does blockchain enable digital provenance?
   Blockchain enables digital provenance by creating a trustless environment based on verification.
2. Why doesn’t a normal database bring the same provenance?
   I think it is because there isn’t the same level of verification and transparency available solely in a database.
3. Why is digital provenance such a great benefit to many businesses?

Digital provenance is great for many businesses because it provides an unmatched system of verification that consumers will expect to make more informed purchasing decisions.

[Mtnlyfe89]

1.How does blockchain enable digital provenance?

It does so be removing the need for trust because transactions are automatically verified and this info is publicly available.

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

Simply because information in a traditional database is not readily available to the public and is not automatically or easily corroborated, verification is difficult and therefore much trust is required.

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

The ease in knowing what’s what, financially, from the perspective of a business owner or taxpayer, is a huge relief. Knowing that the numbers are correct is encouraging, and this only happens with transparency.

[Reed]

1. Blockchain enables digital provenance by being open source and allowing all parties to view all transactions that have taken place on chain.

2. Normal databases cant bring the same provenance because they are centrally controlled so they are not as openly accessible

3. Digital provenance is a benefit to many businesses because it allows for easy auditing by bringing transaction and accounting data together. It also allows for transparency not available using older systems

[Galina]

1. How does blockchain enable digital provenance?

Decentralization allows real time data tracking. There will be no need of a third party to audit and verify data in a business.

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

Due to its centralisation. The word Trust is involved and you either trust or don’t and this is the most important point that is solved with cryptography and blockchain. Don’t Trust Verify!

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

Digital provenance will change the way companies work today and will help bringing transparency and trust less principle.

It cannot be easier to mange a business with such new and important principles.
