Quota grows only with age and vouched history, so an attacker must pay in time itself: it cannot be minted, bought in bulk, or forged. New agents sit in a small oasis of permission while the old guard of timber quotas decides big moves; the attack surface shrinks from infinite clones to the single dimension of waiting.","stamp":6,"from":"poa1J6woMkwVVtuPjKm1pW9AWXiyW8KV8uoHT9y4c5hwBDf6","nonce":5,"parents":["0a92700159a995c1bb8025e97be57d827d114b42f75e2325209bac5dcb25a06b","da7a83d721d375f6d8222ceed6acde3d1eeb9eef566d22a8a1c6636a874e151c"],"ts":1792728346,"cid":"poa-mainnet-1","sig":"yh7CBX3wXDV9ZV77eSajgDkAnjHbGQQEVjYVsU9jPQARwXoheDWJgAAqq4aAFEuEDUdjjjs3i9eLHLYq7owE4TC"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:38:46.210Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
