Cryptoassets

 

1.
Question 1
What is a cryptoasset?

1 point

  • A cryptoasset is a digital representation of a physical asset.
  • A cryptoasset is the same as a cryptocurrency, and these terms can be used interchangeably.
  • A cryptoasset is any digital asset that has value and can be bought or sold online.
  • A cryptoasset is a digital asset that uses cryptography, a peer-to-peer network, and a public ledger to regulate the creation of new units, to verify transactions, and to secure transactions without a middleman.

2.
Question 2
Utility tokens (or “app coins”) are primarily designed to:

1 point

  • function as cash for the Internet
  • provide consumers with access to services or resources within a DApp
  • pay for the computational costs required to execute smart contracts as part of a DApp
  • represent tangible goods, such as gold or oil, in in peer-to-peer markets

3.

1 point

  • Cryptocurrencies
  • Protocol tokens
  • Utility tokens (app coins)

  • By permitting a central authority to control the block size

9.
Question 9
Why is the term “Initial Coin Offering (ICO)” a misnomer?

1 point

  • Because investors aren’t buying “coins” per se, but rather cryptoassets or tokens that can represent many different things (e.g. network access, securities, carbon credits etc.)
  • Because ICOs are essentially no different from existing crowdfunding platforms, such as Kickstarter or Indiegogo.
  • Because the process of raising equity capital through an ICO is identical to that of Initial Public Offerings (IPOs) and Private Investments in Public Equities (PIPEs), which hasn’t changed since the 1930s.

1.
Question 1
A smart contract is:

1 point

Any interaction between two or more parties on a blockchain network.

A browser-based tool capable of viewing all transactions on a particular blockchain.

Software that mimics the logic of an agreement and automates the execution of transactions

2.
Question 2
What is/are the benefit(s) of using a smart contract?

1 point

It reduces mental transaction costs, enabling the computer to do more precisely and more ably what the human mind cannot

It increases predictability, enabling users to measure losses and manage risks more accurately

It provides broad security over users’ business dealings

All of the above

3.
Question 3
A key feature of a smart contract is:

1 point

It cannot be seized, stopped, or redirected to another address once it has been set in motion on a blockchain

It typically entails a zero-sum game wherein one party benefits and the other party loses

It provides incentives for parties to modify or alter the actions that were mutually agreed upon when the contract was formed

All of the above

4.
Question 4
What happens during the performance phase of a smart contract deal cycle?

1 point

Buyers and sellers find each other

The smart contract manages the collateral to affect an outcome

Parties agree upon and commit to the terms of the contract

How does a smart contract differ from a traditional legal contract?

1 point

The language of a smart contract is flexible and corruptible, whereas the language of a traditional contract is rigid and predictable

In general, a smart contract is more complex and contains a greater number of conditions than a traditional contract.

A smart contract is executed by impartial technology (e.g. sensor-guided effectors), whereas a traditional contract contains rules and conditions that are subject to human judgment

All of the above

7.
Question 7
How do smart contracts fit within the traditional legal system?

1 point

While smart contracts are inspired by and can replace some of the functions of traditional contracts, they are largely complementary

An identifier is what a centralized system uses to grant us access to their services

All of the above

2.
Question 2
What is/are the problem(s) with using a birth certificate as an overarching record of existence?

1 point

A birth certificate must be created and verified by a licensed hospital or midwife, yet one quarter of all births go unrecorded worldwide.
