420 Attention concepts¶
A campaign binds sponsor, metadata/audience commitments, verifier, budget, reward rate, per-account cap and time window.
A consent record is account-controlled, reversible state with a monotonic revision and policy commitment.
A proof commits campaign, participant, verifier, observation time, attention units and evidence hash. A single-use nullifier prevents replay.
A reward entitlement is reserved before it becomes claimable. Sponsor campaign funds are segregated liabilities.
