Andreessen Horowitz (a16z) announced a brand new non-public, on-chain voting device for Ethereum builders referred to as “Cicada.”
In a weblog submit, a16z developer Michael Zhu acknowledged current on-chain voting options however famous that a lot of these programs are absolutely public and clear.
Operating tally privateness
By providing non-public voting, Cicada addresses points present in public voting, akin to vote manipulation and improper voter incentivization.
Cicada particularly permits for working tally privateness, which means it conceals the variety of votes for every choice till voting ends. This strategy depends on time-lock puzzles, which conceal particular person votes for a set period of time, and homomorphic time-lock puzzles, which mix the opposite puzzles and conceal the general tally.
Zhu mentioned that Cicada is also used for voter anonymity and poll privateness with the addition of zero-knowledge group membership proofs.
Cicada is a Solidity library, which means it’s suitable with the programming language utilized in Ethereum sensible contracts. Zhu mentioned the library is environment friendly sufficient for use on Ethereum’s mainnet (versus layer 2 networks).
Actual-world use not advisable
Zhu acknowledged on Twitter that on-chain voting is just not “not prepared for high-stakes real-world use circumstances but” however expressed hope for future progress.
Within the meantime, quite a few blockchain initiatives have governance programs that depend on on-chain voting. For instance, Uniswap and different DeFi platforms use on-chain governance to decide on which blockchains to deploy to, whereas the stablecoin challenge Maker makes use of on-chain voting to find out the make-up of its reserves and different selections.
