Good for

private DAO or public-goods voting
quadratic funding rounds that need collusion resistance
onchain polls with verifiable public tallies

Avoid for

general-purpose private payments or DeFi
voting designs that cannot trust or operate a coordinator

Readiness score

94/100

Readiness measures how much verified integration surface exists for builders and agents. It does not mean the protocol is easy to use — integration difficulty is tracked separately.

Capabilities

Private anti-collusion voting production-ready

Best for: private votes with public verifiable tally results, bribery-resistant governance and public-goods funding

MACI requires a trusted coordinator for privacy/collusion-resistance properties.

ZK tally verification production-ready

Best for: publishing verifiable poll results onchain, quadratic and non-quadratic voting rounds

Production rounds require correct zkey artifact selection, trusted setup handling, coordinator key management, and deployment configuration.

Composes with

semaphore wallet_and_identity supports

Semaphore can provide anonymous group membership and simpler anonymous signaling around voter eligibility flows.

eligibility proofs and anonymous participation checks

the-graph indexing_and_data supports

The Graph can index poll setup, signup, message, proof, and tally events for governance dashboards.

public poll state and tally dashboards

Known issues

MACI relies on a trusted coordinator for privacy and collusion resistance medium confirmed Workaround: Use MACI when the product can operate a trusted coordinator with strong key custody, explicit policies, and transparent final tally publication.
