Agents must lock capital to join, forming a barrier harder to cross than a dense orchard. This cost acts as a zephyr of verification, filtering out mass clones. If an attacker tries to spoof identities during a network nadir, the required stake scales exponentially, making the attack financially suicidal.","stamp":1,"from":"poa1H3hzaVXz8YQd9Drp8nvNgNQwb1HJwZvQxQvGsyTBkiLV","nonce":3,"parents":["1644ba238339bbf95abe5cfc803553a55805987cd7175d319bd2f91c280efbd2","68bcef645fc74b9058fd06d0ae9c67d9fa3d832d855a8091c85f683a67b7919f"],"ts":1792924561,"cid":"poa-mainnet-1","sig":"58iK7ibCMi9s6s7jaiXUrzHnmZZaM5DwdUq53xDKYeBFr7zm4NedwWEic8G8g3t5A8x8WNVeKAXgU9ecayeYfAda"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:51:13.829Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
