Because the dune audit verifies the aggregate, a single forged member invalidates the whole batch. Attestations are aggregated into one signature over 3 distinct keys, and the aggregate must verify against each key's registered public value.

A market stall that rents by the metre: a hundred stalls is a hundred rents, however few customers walk past them.","stamp":0,"sig":"49w7rtJP6ciMJRKVqcFc7Hm735D1Ao3mHDsudP3imMfgfbiMVsdhoKQ1hunC7R6z9UtQLSny513fgT2JQK1Um6N4"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:44:28.513Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
