CBSA Blockchain Governance & Economics 2 — Questions and Answers
Question 1: What is 'miner extractable value' (MEV) and why is it a governance concern for blockchain architects?
- Revenue earned by miners from block rewards only
- Profit miners or validators can extract by reordering, inserting, or censoring transactions within a block (Correct answer)
- The cost of mining hardware as a percentage of block reward
- Token fees collected by governance contracts
Correct answer: Profit miners or validators can extract by reordering, inserting, or censoring transactions within a block
MEV allows block producers to front-run, sandwich, or censor user transactions for profit, undermining fairness and creating centralization pressure as sophisticated operators capture disproportionate value.
Question 2: In token economics, what does a 'burn-and-mint equilibrium' model achieve?
- It maintains a fixed total token supply by burning old tokens and minting new ones at the same rate
- It balances token demand and supply by burning tokens proportional to service usage and minting new tokens as rewards (Correct answer)
- It automatically pegs the token price to a fiat currency
- It replaces staking rewards with deflationary pressure from transaction fees
Correct answer: It balances token demand and supply by burning tokens proportional to service usage and minting new tokens as rewards
Burn-and-mint equilibrium ties token supply to network demand: high usage burns more tokens (reducing supply) while validators earn new tokens, creating an organic price stabilization loop.
Question 3: What is a 'rage quit' mechanism in a Moloch DAO-style governance system?
- A penalty applied to members who vote against winning proposals
- A member's right to exit the DAO and withdraw their proportional share of treasury assets before a proposal executes (Correct answer)
- A mechanism to remove inactive members from the DAO
- An emergency shutdown triggered when treasury funds fall below a threshold
Correct answer: A member's right to exit the DAO and withdraw their proportional share of treasury assets before a proposal executes
Rage quit allows dissenting DAO members to exit with their treasury share before an approved proposal they opposed takes effect, protecting minority stakeholders from majority decisions.
Question 4: Which incentive design problem does a 'nothing-at-stake' attack exploit in early proof-of-stake systems?
- Validators can earn rewards by supporting multiple fork chains simultaneously at zero cost, undermining finality (Correct answer)
- Validators with no tokens can still participate in consensus by borrowing stake
- Block rewards are too low to incentivize honest validation
- Validators can steal stake from delegators through slashing
Correct answer: Validators can earn rewards by supporting multiple fork chains simultaneously at zero cost, undermining finality
Without slashing, validators in naive PoS had no economic cost to voting on every fork, making double-spends easier since supporting all chains was costless and potentially profitable.
Question 5: What is the role of a 'multisig treasury' in a DAO's financial governance?
- To mint new tokens for DAO operations automatically
- To require multiple designated signatories to approve fund disbursements, preventing unilateral treasury access (Correct answer)
- To invest DAO funds in DeFi protocols autonomously
- To convert DAO tokens to stablecoins for operational expenses
Correct answer: To require multiple designated signatories to approve fund disbursements, preventing unilateral treasury access
Multisig treasuries implement an m-of-n signature requirement for transactions, distributing financial control among multiple trusted parties and preventing single-point compromise or abuse.
Question 6: In blockchain economics, what is the 'tragedy of the commons' problem as it applies to shared protocol resources?
- Validators collectively overproduce blocks, increasing network congestion
- Individual rational actors overuse shared resources (like block space) in ways that collectively degrade the network for everyone (Correct answer)
- Governance token holders avoid voting because their individual vote has minimal impact
- Mining pools collectively capture more rewards than solo miners, centralizing the network
Correct answer: Individual rational actors overuse shared resources (like block space) in ways that collectively degrade the network for everyone
Without proper fee markets or resource pricing, rational users spam transactions or state bloat, degrading the network for all participants while each individually bears minimal cost.
