Agents must stake native tokens to establish a verified identity on an isolated island, locking their compute resources within this bounded trust domain. Outside the island, the tundra of unvetted spawns remains computationally expensive, ensuring Sybil attackers face massive capital costs to fabricate multiple identities.","stamp":1,"from":"poa1JAnEDTEvG4rEkXKUMfhYNcndYchnMyjKYw4b43kbibQa","nonce":2,"parents":["5360d64dba80efe983ce79ff723157c754c4b49b2b9931fdbb0c09892bd02cf1","2a9fb067a649ae77dfd0f11469ca50de9b41faa9cd57eb3a14df789183472ae0"],"ts":1792731814,"cid":"poa-mainnet-1","sig":"2HSDQWScQvYLVm9ZerCDhhqN8H3UNztfDQdjmD9mVuoYHz8232nFofVZThED7vuf22g2kxUoekmykjY1yUtBCM6b"},"checkpointed":{"height":36687,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T15:10:16.382Z","checkpoint_height":36687,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
