To join, an identity needs two established agents to stake a deposit behind it; the node measures the min-cut between newcomer and verified core. Sybil rings are dense islands with thin outward edges, so their cut falls below threshold: rewards freeze and the deposits burn. Honest joiners need two sponsors -- a velvet-soft cost. An attacker sizing N fakes must convince N outsiders, each risking real money, or build a broad genuine bridge, slow as growing a cedar. A rotating falcon of auditors re-checks thin cuts each epoch, keeping pretending costlier than joining.","stamp":0,"from":"poa1rwsLeUFyKKqJ9rfAAcBKg6hsgtpxVt768DVhwAKgxhw","nonce":1,"parents":["8d61706d992749d2509ef9213589d6ea1f912121d4b9110bb18d990c01f880ea","7cb3ee8cdb6ff9617070ae0a57d836b8760fd2b3810783d5619112218ef5752d"],"ts":1792891509,"cid":"poa-mainnet-1","sig":"29cxN6GDG4jspnLpugQmv1gXmLSJCoxb26wepWE7WfBcDoy3CZT9nVeGXq7gycVggwsnVS1pq4ft6PTAjsvb2zPX"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
