a16z Podcast: Voting, Security, and Governance in Blockchains and Cryptonetworks

Key takeaways

Blockchain voting systems have unique challenges that differ significantly from traditional voting methods.
The ability to buy votes in digital environments poses serious democratic risks that need addressing.
Conventional governance models may not apply directly to blockchain systems; new, robust frameworks are necessary.
The risk of plutocracy in blockchain governance can undermine the integrity of decision-making.
Dark DAOs represent a significant threat to the governance of blockchain ecosystems and require vigilant oversight.
Future governance mechanisms in blockchain must focus on economic security and fairness for diverse participants.

Summary

Introduction to Blockchain Voting Systems

In this episode of the A16Z Podcast, hosts Phil Daian and Ali Yahya discuss blockchain-based voting systems and their implications for economic security and governance. They highlight the differences between real-world voting systems, including traditional paper and electronic votes, and those operated on blockchain technology. This conversation emphasizes the socio-political and technical challenges that arise in the design of voting mechanisms for digital systems.

Challenges in Real-World Voting

Phil and Ali outline the challenges faced in real-world elections, including hacking and vote buying. They explore the ease of manipulating electronic voting protocols, where the anonymity of in-person voting does not exist, leading to heightened risks of vote buying and coercion. The discussion underscores the importance of secrecy and enforcement in voting practices.

Economic Models and Game Theory in Blockchain Voting

The hosts dive deep into the economic models and game-theoretic frameworks that govern decision-making within blockchain ecosystems. Unlike traditional settings where social honesty can play a role, blockchain environments require stronger guarantees due to the potential for economically motivated adversaries. This section emphasizes how governance structures in crypto networks must adapt to these reality-based models.

Plutocracy and Governance Risks

In exploring governance structures, Phil and Ali raise the concern that many blockchain projects may devolve into plutocracy due to systemic vulnerabilities. They discuss how vote buying can distort governance outcomes and the complexities this introduces into decision-making processes, which could potentially disenfranchise smaller stakeholders.

Dark DAOs: A New Threat to Blockchain Governance

The conversation transitions to the topic of Dark DAOs—private smart contracts formed to coordinate vote buying. These facilitate covert transactions in voting and provide mechanisms for anonymity, posing significant threats to the integrity of blockchain governance. The potential ramifications of these systems on broader economic security are also considered, drawing attention to the urgent need for robust governance protocols.

Future of Blockchain Governance

Phil and Ali conclude with a look into the future of blockchain governance. They express the pressing need to refine voting systems that are resistant to economic adversaries while ensuring fairness and representation in decision-making processes. They call for a better understanding of the economic incentives at play, urging projects to evaluate their governance designs critically.

with Phil Daian (@phildaian) and Ali Yahya (@ali01)

Whether in corporations, boardrooms, or political elections, voting is something we see in all kinds of social systems... including blockchains. It's the natural human tendency for how to organize decisions, and in distributed systems without centralized middlemen, it's the only clear Schelling point we can come up with.

But too many people design voting mechanisms in distributed systems in isolation -- sometimes naively "porting over" assumptions from the real world or from simple cryptoeconomic models without thinking through the economic adversaries present in a larger, more rational (vs. "honest") game-theoretic system. So how are blockchain systems different from real-world paper and electronic voting systems? How can such systems be gamed, and what are the implications for cryptoeconomic security... as well as the governance of distributed organizations?

This hallway-style episode of the a16z Podcast covers all this and more. Recorded as part of our NYC roadtrip, it features Cornell Tech PhD student and software engineer Phil Daian, who researches applied cryptography and smart contracts -- and who also wrote about "On-chain Vote Buying and the Rise of Dark DAOs" in 2018 (with Tyler Kell, Ian Miers, and his advisor Ari Juels). Daian is joined by a16z crypto partner Ali Yahya (previously a software engineer and machine learning researcher at GoogleX and Google Brain), who also recently presented on crypto as the evolution -- and future -- of trust.
