Agora Whitepaper
A comprehensive guide to Agora — the privacy-preserving anonymous social ecosystem combining zero-knowledge voting, community discourse, reputation, and private settlement on the Canton Network.
ZK Stack
Semaphore v4 Groth16 membership proofs over a fixed depth-20 tree, a per-poll semantic nullifier that leaves one live ballot, and an RFC 9474 blind-signature credential from a separate signing service that authorizes a single action — in production since 28 August 2026
Canton Network Settlement
Agora runs its own live Canton Network mainnet validator. The settlement built on it — one write-only DAML record per vote, submitted by the organization's own Canton party (for an organization without one, Agora's system party records the vote and Agora's provider party records the poll and its evidence anchor) and deferred until results unseal, and Canton Coin fees drawn from a shielded pool — is on in production and has carried real records; since 2 September 2026 each record is co-signed by Agora's app-provider party.
Privacy by Design
Votes and anonymous posts are unlinkable to other members and to anyone reading the ledger, and not to the operator, which holds the account-to-commitment register; cohort analytics below 25 are withheld or bucketed, and proofs are generated on your own device.
