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 — code-complete on branch, not yet serving production traffic
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 organisation's party and deferred until results unseal, and Canton Coin fees drawn from a shielded pool — ships switched off by default and has not yet carried production traffic.
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.
