CBSA Blockchain Governance & Economics 3

Question 1

What is 'futarchy' as a blockchain governance model?

Accepted Answer

Governance by prediction markets where policies are chosen based on which option produces the best forecasted outcome metric

Answer

Futarchy, proposed by Robin Hanson, uses prediction markets to select policies: voters define success metrics, and markets bet on which policy best achieves them, theoretically aggregating dispersed information.

Question 2

Why is 'governance minimization' considered a design virtue in DeFi protocol architecture?

Accepted Answer

It limits the attack surface for governance exploits by keeping protocol parameters immutable or tightly scoped

Answer

Reducing governable parameters limits the damage a governance attack or cartel can cause, and protocols with fewer adjustable levers are harder to manipulate for extractive purposes.

Question 3

A CBSA architect is designing an enterprise blockchain consortium governance model. Which structure best balances decentralization with accountability?

Accepted Answer

Federated governance with a voting consortium of member organizations, each operating validator nodes with equal voting weight

Answer

Federated consortium governance distributes control among vetted member organizations while maintaining accountability and regulatory compliance, suitable for enterprise environments requiring known participants.

Question 4

What is 'coin voting cartels' and how do protocol designers mitigate this governance risk?

Accepted Answer

Large exchanges lending governance tokens to collude on votes; mitigated by separating voting rights from transferable tokens

Answer

Exchanges or large holders can borrow or lend tokens solely to vote, forming cartels; designs like non-transferable governance tokens or quadratic voting reduce concentrated voting power.

Question 5

In designing token emission schedules, what is the trade-off between high early inflation and low long-term inflation?

Accepted Answer

High early inflation attracts validators but dilutes early investors; low long-term inflation ensures scarcity but may reduce validator incentives as fees must cover security costs

Answer

Front-loaded emission bootstraps network security and participation, but must transition to a fee-based security model as inflation drops, requiring sufficient organic transaction volume to maintain validator incentives.
