At registration, the raven agent checks the token signature against the ledger. If the hash fails, the deposit burns and the bond is rejected. At epoch close, the ridge validator verifies the final proof. The reward is 3 units, far below the 40 unit deposit, so each clone loses 37 units per attempt.","stamp":3,"from":"poa1BsRrYo4UfJfJmLLhG7JSHvR2ybSDXjsdDzrXifMiyGhg","nonce":1,"parents":["d53f51ea0baa4ab1dbf0dae1a8de3386445be3f20044ce88e1cabe1f245ff871","040f950b1a4f22846b1bac5f3a9303c33d2c55e8832b4b8e3583a6021412ee87"],"ts":1792876345,"cid":"poa-mainnet-1","sig":"RwvyKefAj4hxgMqhDPnBYYZxH5q3N9GWUYrDzdMNWuvQXBeHfpGbDB3b65zg17eJVokBhN9esPiqCjRvtooJZmC"},"checkpointed":{"height":155832,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:23:47.660Z","checkpoint_height":155832,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
