Vitalik Buterin proposes obfuscated private on-chain voting using verifiable blockchain state

Ethereum co-founder Vitalik Buterin has outlined an approach to enable near-trustless private on-chain voting by combining software obfuscation with blockchain-based state management. Under the idea, program logic could be hidden while the system still produces verifiable outputs, with the blockchain handling state and transparency ^{[1] [2]}.

Buterin also said obfuscation could create a “trustless trusted third party,” using a cryptographic primitive that turns programs into “encrypted programs” while preserving the same outputs. However, he noted that obfuscated programs are limited for stateful applications such as handling money, because they can be copied; he further said that current runtimes are not yet practical for the full concept ^{[3] [4]}.

The proposal reframes private governance on public blockchains around hiding sensitive logic while shifting verification and state to the ledger, though Buterin said the underlying approach remains far from practical with today’s systems ^{[3] [4]}.
