Using on-chain voting for information aggregation with Brett Falk | a16z crypto research talks

TL;DR

This analysis explores the use of approval voting and initiative voting in blockchain governance, considering the effectiveness of information aggregation and the vulnerability to malicious attacks.

Transcript

uh welcome everyone to today's a16z crypto research seminar very pleased to welcome Brett Falk who's a professor at the University of Pennsylvania um did his grad work at UCLA uh finished their 2010 working mostly on multi-party computation stuff I guess NPC yeah so he works on lots of different parts of the blockchain space including some stuff th...

Key Insights

• ⚾ Committee-based consensus utilizes approval voting to elect committees, offering flexibility in selecting committee members and enabling additional functions beyond consensus.
• 😀 Initiative voting in DAO governance faces challenges related to the vulnerability of proposals to manipulation, potential for information aggregation limitations, and the need to address minority stakeholders' concerns.
• 👊 Continuous voting can provide more dynamic and continuous decision-making in DAO governance, but its effectiveness in information aggregation and vulnerability to malicious attacks needs further examination.

Questions & Answers

Q: What is the difference between committee-based consensus and DAO governance?

Committee-based consensus involves electing a committee that participates in the consensus algorithm, ensuring the protocol's security. On the other hand, DAO governance focuses on decision-making within a decentralized autonomous organization, including voting on proposals and determining the organization's parameters.

Q: How does approval voting work in committee-based consensus?

In approval voting, voters can approve of multiple candidates instead of casting a single vote. The committee is then formed based on the candidates who receive the most approvals. This allows for more flexibility in selecting committee members.

Q: What are the advantages and disadvantages of initiative voting in DAO governance?

Initiative voting allows for proposals to be made and voted upon, enabling the DAO to adapt and evolve. However, initiative voting is susceptible to strategic manipulation, where malicious actors may introduce proposals to influence the outcome in their favor.

Q: How does continuous voting differ from other voting mechanisms?

Continuous voting, as used in MakerDAO, allows for ongoing voting on proposals, without restricting voting to specific time windows. This provides more flexibility for participants to express their preferences continually.

Summary & Key Takeaways

• The analysis focuses on two types of blockchain voting: electing blockchain committees and decentralized autonomous organization (DAO) governance.

• For electing committees, committee-based consensus is used, which involves electing a consensus committee based on proof-of-stake or proof-of-work mechanisms. Approval voting is commonly used in this context.

• Initiative voting, also known as amendment voting, is employed in DAO governance, where voters propose yes or no initiatives, and a majority vote determines the outcome. Continuous voting is used in MakerDAO, allowing voters to vote on proposals continually.

• The analysis examines the efficacy of approval voting and initiative voting in information aggregation and their vulnerability to malicious attacks.
