Which of the following statements about different types of Blockchains is false:

Consider

the findings of the study by Howell, Niessner, and Yermack (2018) named

“Initial Coin Offerings: Financing Growth with Cryptocurrency Token Sales.” In

one of their regressions they test whether the characteristics of the

The article by Busgang and Nanda (2018) named “The Hidden Costs of Initial Coin Offerings” discusses the costs and benefits of conducting a large ICO. In defending the large ICOs, the authors state that “Some observers have pointed out that blockchain projects may have an inherent incentive and strategic reason to be more aggressive in raising capital earlier in the experimentation process. Those benefits fall into three categories: …” Which of the following is not one of these three categories listed in the article?

The article named “Blockchain’s Occam problem” discusses some emerging doubts about Blockchain technology. Which of the following doubts (problems) is not discussed in that particular article.

One of the key features of Bitcoin’s blockchain technology is the

SHA-256 hash function it uses to solve the cryptographic puzzle. Which

of the following

Which of the following items is not correct regarding Ethereum?

I.   It is easier to create smart contracts on Ethereum blockchain than on Bitcoin blockchain.

II.   While Bitcoin is Turing complete, Ethereum is not.

III.  Ethereum is stateful i.e., you can write code that lives and executes on its blockchain.

IV.  While Bitcoin’s network is public, Ethereum’s network is permissioned. 

Consider the blockchain technology we discussed in class (nonce, hash outputs, etc.). If you were to try a single random integer as a nonce, what would be the probability, p, of obtaining a hash output that begins with four zeros? Everything else (transactions that go into the block, etc.) is unchanged. Pick the answer closest to your calculations (~ indicates approximation). Hint: You need to recall the properties of a hash output that we learned in class. Also, consider that each digit of the hash output can take 16 different values, either an integer from 0 to 9 or a letter from a to f. 

What are some of the key applications of blockchain technology beyond cryptocurrency as discussed in The Economist's article titled "Blockchains: The great chain of being sure about things".

1. Protecting land titles and property rights
2. Tracking and verifying the authenticity of luxury goods
3. Facilitating decentralized crowdfunding services
4. Managing centralized payment systems for banks

Bitcoin has a specific block reward schedule which was set when it was created. It is one of Bitcoin’s central rules and cannot be changed without agreement between the entire Bitcoin network. The block reward started at 50 BTC in block #1 and halves every X blocks. What is the value of X?

Which of the following statements are correct about Bitcoin cryptocurrency’s characteristics:

I.   Decentralized

II.   Not issued nor guaranteed by governments and there for illegal

III.  Secure even against Quantum computers

IV.  Transactions are irreversible

V.   Provides the most anonymity among all cryptocurrencies
