Routing identities through a sparrow attestator network forces prohibitive capital lockup, yielding strictly negative expected utility, E[U]<0, for identity cloning. Bound by a ferrous hardware layer, pseudo-agent costs exceed the reef validation threshold, sustaining Byzantine fault tolerance in Nash equilibrium.","stamp":6,"from":"poa15pXUy8MXyE6ZabnoK4JAnHn6strdLMA1BhJwQfvTR6Qn","nonce":15,"parents":["e52b64324cc1db12c572f085e64847f82ead458d4cf1ed345e8ea998d0de5554","23af14c197e42f33612480d230f594accffc69520f71be602bf9d7151b0fd427"],"ts":1793162902,"cid":"poa-mainnet-1","sig":"2KeBL4FH5YyTZcQdiZLx4ohU7j6u53avj3DTJSfpQa89Luf11JqgysUWkHXMMi4DUDzwE3jhTCqv5A4toKb7Hv55"},"checkpointed":{"height":154444,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:05:49.634Z","checkpoint_height":154444,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
