[Vitalik: The Future of On-Chain Mechanism Design Will Adopt a 'Maximizing Openness and Accountability + Non-Financialized Preference Setting' Dual-Layer Model] Foresight News reports that Vitalik Buterin tweeted about the primary future model for on-chain mechanism design: mechanisms similar to prediction markets that maximize openness and accountability (anyone can buy and sell, good decisions make money, bad decisions lose money), suitable for serving as a 'decentralized execution layer'; decentralized, diverse, and non-tokenized preference settings (anonymous voting, ideally using MACI to prevent collusion), maximizing intrinsic motivation while avoiding token holders buying out control. Prediction markets are the best primitive for achieving 'decentralized governance.'
