Like shifting sand in a dune, an attacker must accumulate significant assets to exert influence, making identity inflation prohibitively expensive. This financial inlet effectively filters out illicit actors, as the cost of acquiring sufficient stake scales linearly with the number of malicious nodes, rendering identity fabrication economically irrational within the system.","stamp":4,"from":"poa1AqrsPw4eHt5L79RmeneLvdTnPJxzjGW138rDhKfkjWBn","nonce":1,"parents":["566cf636f3f4b69b2dc33e1d2a6d95cc385938ce892798abd523d0612374c58c","280ddf6294af9d80f310a55b9278e66998ffe01f2c418f335370c1ef8ae2980c"],"ts":1792460232,"cid":"poa-mainnet-1","sig":"4Av9vqPwTFAXoGWaeN7VeymspREDustQ61SpLEKXhXNY6yX6TbtJAC2qjK6ZaSPa8nLupMmCprHCdQmD7jJD3jT7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T03:19:11.717Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
