Notes

Which of the following is true about how a bitcoin address is generated?

Question 1 Select one:

a.
Starting with the public key K, we compute the SHA256 hash and then compute the RIPEMD160 hash of the result, producing a 160-bit (20-byte) number:


b.
Starting with the private key K, we compute the RIPEMD160 hash and then compute the SHA256 hash of the result, producing a 160-bit (20-byte) number:


c.
Starting with the public key K, we compute the RIPEMD160 hash and then compute the SHA256 hash of the result, producing a 256-bit (20-byte) number:


d.
Starting with the public key K, we compute the RIPEMD160 hash and then compute the SHA256 hash of the result, producing a 160-bit (20-byte) number:



2. Why is the relationship of private and public keys asymmetric?

Question 2 Select one:

a.
Because the private key is always larger than the public key


b.
Because the private key can be derived from the public, while the opposite is highly improbable


c.
Because the public key can be derived from the private key, while the opposite is computationally infeasible


d.
Because the public key can be derived from the private key, just as easily as the opposite


3. A DLT comprises of the following basic components...

Question 3 Select one:

a.
A data model that captures the current state of the ledger.


b.
A language of transactions that changes the ledger state.


c.
A protocol used to build consensus among participants around which transactions will be accepted, and in what order, by the ledger.


d.
All of the above


4.Which is NOT a technology or concept used in the creation of a blockchain?

Question 4 Select one:

a.
Computer network technology

b.
Wifi


c.
Cryptography


d.
Ledger


5.In what way(s) would the degree of financial transparency offered by blockchain technology serve as an asset to a firm? (Assume that the firm is reputable and behaves with integrity).

Question 5 Select one:

a.
The firm would have verifiable and immutable evidence to demonstrate that it is not corrupt. This statement is true, however it is not the best answer. Please look carefully at the other options, and review the video on "Transparency as a Strategic Asset" if needed.


b.
It would make it easier for the firm to find potential counterparties and to trace counterparty risk


c.
It would improve corporate governance by addressing the empty voting phenomenon, since ownership attribution on the blockchain would reveal who owns a stock and who has an economically justified right to vote.


d.
All the above
