Ethereum co-founder Vitalik Buterin has proposed a two-layer approach for the future of onchain mechanism design. According to Buterin, the first layer should focus on maximizing accountability through openness, ensuring transparency and trust in blockchain operations. The second layer should be decentralized and pluralistic, designed to foster intrinsic motivation by providing a flexible and inclusive environment for participants. This dual-layer strategy aims to enhance both the reliability and creativity within blockchain ecosystems.
