Vitalik Buterin, co-founder of Ethereum$ETH and influential blockchain researcher, has outlined a forward-looking vision for future on-chain mechanism design, advocating a “two-layer structure” that combines accountability with decentralized, capture-resistant preference formation. Buterin’s concept seeks to address governance and coordination challenges in decentralized systems by separating execution from preference judgment — a move away from token-based voting dominance toward more resilient, intrinsic mechanisms.
In a recent post on X (formerly Twitter) responding to community discussions on decentralized platform design, Buterin described a framework consisting of two distinct layers:
A highly open and accountable execution layer — akin to prediction markets, where participants’ decisions are subject to economic incentives and penalties.
A decentralized, pluralistic preference and judgment layer — designed to be capture-resistant, non-financialized, and non-token-based, favoring anonymous voting mechanisms such as MACI to prevent collusion and centralization of influence.
How the Two-Layer Structure Works
According to Buterin’s description, the first layer functions similarly to prediction markets, where correctness is rewarded and incorrect judgment results in financial loss. This structure promotes accountability because participants’ stakes are tied directly to outcomes, making it difficult for bad actors to influence decisions without economic risk.
The second layer focuses on establishing collective preferences and judgments in a pluralistic and decentralizedmanner. Buterin emphasized that this layer should avoid token-based governance — where ownership equates to voting power — because such systems are vulnerable to capture, including 51 % attacks or disproportionate influence by large holders. Instead, he proposed anonymous voting systems, ideally implemented using Minimal Anti-Collusion Infrastructure (MACI) or similar privacy-enhancing protocols that make it difficult for participants to coordinate vote buying or dominate outcomes.$ETH
