Blockchain Technology DeFi and Tokenomics 1 — Questions and Answers
Question 1: What does DeFi stand for in the context of blockchain?
- Decentralized Finance (Correct answer)
- Digital Financial Infrastructure
- Distributed Fund Index
- Delegated Finance Interface
Correct answer: Decentralized Finance
DeFi stands for Decentralized Finance, referring to financial services built on blockchain networks without traditional intermediaries.
Question 2: Which protocol pioneered the concept of Automated Market Makers (AMM) in DeFi?
- Compound
- Aave
- Uniswap (Correct answer)
- MakerDAO
Correct answer: Uniswap
Uniswap pioneered the AMM model using a constant product formula (x*y=k) to enable permissionless token swaps without order books.
Question 3: What is a liquidity pool in DeFi?
- A reserve of a single token locked in a smart contract
- A collection of tokens locked in a smart contract to facilitate trading (Correct answer)
- A group of validators who secure the network
- A wallet holding staked tokens
Correct answer: A collection of tokens locked in a smart contract to facilitate trading
A liquidity pool is a collection of two or more tokens locked in a smart contract that provides liquidity for decentralized exchanges.
Question 4: What is the primary purpose of a governance token in a DeFi protocol?
- To pay gas fees on the network
- To represent collateral for loans
- To allow holders to vote on protocol decisions (Correct answer)
- To earn staking rewards from validators
Correct answer: To allow holders to vote on protocol decisions
Governance tokens grant holders voting rights to propose and vote on changes to the protocol's parameters, upgrades, and treasury use.
Question 5: What is 'yield farming' in DeFi?
- Mining new tokens using proof-of-work
- Providing liquidity or staking assets to earn rewards across protocols (Correct answer)
- Generating NFTs from existing tokens
- Validating transactions on a proof-of-stake chain
Correct answer: Providing liquidity or staking assets to earn rewards across protocols
Yield farming involves moving assets across DeFi protocols to maximize returns by earning trading fees, interest, or token incentives.
Question 6: What is 'impermanent loss' in the context of DeFi liquidity provision?
- The gas fees paid when depositing into a pool
- The temporary reduction in value compared to simply holding assets due to price divergence (Correct answer)
- The permanent loss of tokens due to a smart contract bug
- The fee charged by a protocol for withdrawing liquidity
Correct answer: The temporary reduction in value compared to simply holding assets due to price divergence
Impermanent loss occurs when the price ratio of pooled assets changes after deposit, causing the LP's value to be less than if they had simply held the assets.
Question 7: Which of the following best describes a stablecoin?
- A token whose value is pegged to a stable asset like USD or gold (Correct answer)
- A cryptocurrency with low transaction volume
- A blockchain token that cannot be transferred
- A token exclusively used for paying network fees
Correct answer: A token whose value is pegged to a stable asset like USD or gold
A stablecoin is a cryptocurrency designed to maintain a stable value by pegging to a reference asset such as the US dollar or a commodity.
