Tally Zero is a completely decentralized voting application designed to facilitate onchain voting via the InterPlanetary File System (IPFS) through thirdweb. It serves as a fundamental tool to ensure that people can always vote onchain, even if all the more complex front ends, such as Tally and Boardroom, are down. 

It ensures that governance frontends are not a single point of failure for DAO governance. Without Tally Zero, if all all governance frontends were down, users may not be able to vote on important DAO proposals. Instead, Tally Zero does not rely on any central authority or single point of failure, making it resilient and secure.
