On June 6th, the decentralized governance infrastructure Dora Factory has completed the deployment of a million-person-scale MACI voting contract on the Dora Vota chain, launching the second round of the AEZ Quadratic Grant quadratic privacy governance round. This MACI vote will allocate part of the amount of AEZ quadratic funding provided by AADAO, and 1.05 million staking addresses on CosmosHub will enter the whitelist of this round of large-scale MACI voting rounds. Dora Factory has airdropped Dora Vota network fees to 1.05 million addresses, and the additional fees related to MACI contract interaction will be covered by the MACI fee gas station. CosmosHub Passed Historic Governance Resolution Prop #917, awarded one million dollars to the Dora Factory and DoraHacks AEZ Quadratic Grant Project to support the public goods and application chain ecosystem open source project funding activities over the next two years. This MACI voting round is the first experiment of large-scale on-chain privacy governance technology jointly conducted by Dora Factory and the crypto community.
