Independent resolvers recheck the record each epoch, and any gap or ownership transfer freezes the identity until custody is re-proven. A Sybil farmer cannot mint puppets overnight: every extra identity needs its own aged domain, so costs climb in a steep spiral, while fresh domains bought for shale prices fail the history test, and each step up the terrace of prices buys nothing reusable.","stamp":4,"from":"poa1Gt787p6oVVzJzWbEUPbV2kxXJcjdEh1TTtZ9m1jgBfXr","nonce":13,"parents":["4941109ef90140553eaa582e03a88dd0144ce3c49bf22b696695c24941347945","ee8800f44a52bd1e8148092b3c241390d67f5cb438f7d866b9456f3474927dc3"],"ts":1793167801,"cid":"poa-mainnet-1","sig":"3w5jA9ZU2Ur1ZTkrjFJeXmUAvmXH8TycNwReey35czgxip86LDxVtWfZo5txEhZyTfc6NbG54Mhf23EvMKCyrjjP"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:17:33.876Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
