Blockchain and Bitcoin 101

  1. How does blockchain enable digital provenance?
    Blockchain brings together the transaction and accounting and origin information in a decentralized ledger that can be audited and verified by anyone, making it trustless. Information written to the blockchain can never be changed or rewritten
  2. Why doesn’t a normal database bring the same provenance?
    Normal databases can be subject to “gatekeeper” controls, the information contained in a database can be changed or modified and redacted therefore they dont bring the same provenance and need to be from a “trusted” source
  3. Why is digital provenance such a great benefit to many businesses?
    Digital Provenance is a great benefit to a business because information regarding a product can be audited and verified by anyone, this could bring a competittive advantage for the business

How does blockchain enable digital provenance?
Blockchain is digital database that can store data without removing.Only add and everyone can track transaction.
No authority control like bank.No need to ask permission to do anything.It is decentralize.Trustless.

Why doesn’t a normal database bring the same provenance?
Normal database can be manipulate by somebody who have permission to execute command.
Normal database also store at the center location instread of multiple node on network to verify transaction like blockchain

Why is digital provenance such a great benefit to many businesses?
It can audit in real time.No need to trust third party and secure.

1-The information is verified by a lot of nodes and then chained to the previous block. After it is connected to the blockchain, it is immutable.
2-Normal databases control by organizations. Because there is central control, it’s not possible to bring the same provenance.
3-Trustlessness. In blockchain technology, you don’t have to count on anyone’s word. There is no conflict of interest because blockchain doesn’t care about who you are.

  • How does blockchain enable digital provenance?

Because of its immutability. Its digital all the way.

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

they are corruptable
Takes too much time and very expensive.

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

rely on verification, hence, its trustless, its fast, private and has access to public.

  2. Because it is base on trust more than verification.

Blockchain enables provenance because every transaction can be tracked in real-time.

In a normal database, the account layer & transactional layer are separate making it difficult to accurately track every transaction in real-time.

The benefit of provenance is it removes trust in a transaction, instead of trusting something was done, we can now verify it was done.

  1. Blockchain technology CAN ONLY add ‘x’ NOT REMOVE ‘x’, WHILE tracking every addition or transaction providing transparency.
  2. data is not immutable and could be changed by the owner of the database
  3. Creates opportunity for supply-chain operations, Real Time audit or access records on transactions with chronological history of all transactions. This historical transparency can also fight corruption & tax evasion

  1. How does blockchain enable digital provenance?
    Records cannot be erased, its public and can be checked, it is permissionless-anyone can add
  2. Why doesn’t a normal database bring the same provenance?
    You would have to trust the database owner. Can add and subtract from another
    database but only add on blockchain.
  3. Why is digital provenance such a great benefit to many businesses?
    Businesses can prove easily, easy verification by customer/consumer, its trustless.

Homework on Provenance - Questions

  1. its not changeable or able to be manipulate by anyone

  2. you can manipulate and remove enteries in a standard database, you are not able to do that on a blackchain, once it is there, it stays there and cannot be removed.

  3. because it is real time, less admin, also able to have more real time data able to make better decisions for your business

  2. Why doesn’t a normal database bring the same provenance?
    a) Changes can be made to a normal database (without any verification)
  3. Why is digital provenance such a great benefit to many businesses?
    It removes the need for trust or for (independent) third parties to do the checks

  1. Combining the account and transaction information into one. All of this info on a public ledger for anyone to verify and cannot be removed.
  2. Information from the account and transaction are separate. And can be removed from the database.
  3. Being able to keep tract of all transactions. The ability to become trustless.

-by being decentralized it allows the system to be trustless. No central authority or government can manipulate the system.

  • Because normal databases can be manipulated and controlled by a central authority.

-digital provenance allows us to verify instead of trusting the suppiler

  1. It is a trustless ledger which can only be written to and can be read in real time.
  2. A normal database is separate from the transaction and thus not in real time, and can also be altered.
  3. It is fast, trustless, and more accessible.

  1. It is a digital database, a public ledger if you will, where every transactions is stored, and none of it can be removed.
  2. A ''normal" database is controlled by a third party who maintains it and everyone else needs to “trust” the third party not to manipulate it (remove or erase data).
  3. The ease which it offers to verify/track data in real time and not have to take someone’s word for it.

  1. DLTs, in particular blockchain in this instance, enables provenance because records/blocks entered on the chain (ledger) are immutable i.e. “set in stone”, so once written and committed, they cannot be changed or removed due to the sequential correlation of the hash functions of the merkel tree.

  2. A normal database doesn’t bring the same provenance because the exact opposite is true. Records in tables can be amended, reordered, deleted etc. Even relational databases which may be replicated for resilience etc can crash and not synchronise in real-time so data loss can occur.

  3. Digital provenance is such a great benefit to many businesses for a variety of reasons including governance, safety, integrity, honesty etc. There are so many use-cases which would benefit from this such as for example Uber where the drivers, cars etc are audited in realtime so reduces risks of say an illegitimate driver kidnapping someone. Another good example could be corrupt cops arresting people falsely or changing evidence after the incident. Medical records and staff including paramedics administering wrong or incorrect medication etc. Insurance companies, the legal or judicial system and many other businesses could really benefit from digital provenance.

  1. Blockchain network creates an immutable ledger of transactions that is public. It cannot be changed or altered.

  2. A normal database is made of tables with variables and can be altered. Blockchain uses computers or nodes to keep track and verify each transaction. Every computer has to agree on something in order for a transaction to be made.

  3. It will give buisnesses an easy way to collate data and be able to verify key information.
