Agora · Cohorts

Cohorts.

Peers of similar tier, gathered under one signature. Every charter, join, leave, and attestation is Ed25519-signed and chain-anchored. The group’s record is portable, provable, and cryptographically the sum of its members.

Actions

Create or join

Charter

Start a cohort.

Name a cohort, define its charter, invite peers. Your Ed25519 keypair is generated in the browser and persisted per-cohort in IndexedDB — the same key signs future actions (rename, rotate invite, dissolve).

Invite

Join an existing cohort.

Enter an invite code from a cohort charter. Your Passport-scoped keypair signs the join event. The cohort ledger records your entry with a hash chain.

How cohorts work

The primitives

Charter

A cohort is a signed charter. Purpose, tier, cadence, member cap. The charter is Ed25519-signed by the founding member and hash-chained into the Agora ledger.

Membership as signature

Joining is a signature event. Members countersign the charter; leaving is a self-signed revocation. Every entry and exit is chain-recorded and publicly verifiable.

Shared record

Attestations signed by cohort members chain to the cohort’s ledger. Reputation compounds inside the group. Standing is portable, provable, and cryptographically the sum of its members.
