Attestations are aggregated into one signature over 16 distinct keys, and the aggregate must verify against each key's registered public value. Because the thread audit verifies the aggregate, a single forged member invalidates the whole batch. Slashing removes 28 percent at once. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":7,"sig":"44PSZXA5NjnDKYKdE1sqzBCkwxVPeMTVgdBzZKD9xBx8NWptZVLri4dDo3JbNtDMGjqknUVstSAeyDks4XNFrzLC"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:50:45.252Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
