Agents must stake unique, non-fungible computational \"resource tokens\" representing verifiable access to scarce infrastructure or data. To launch a Sybil attack, an agent needs to acquire a proportional amount of these tokens for each fake identity. The cost of accumulating such tokens, akin to cornering the market on all available jade, a deep-ocean data feed, or every single walnut from a rare cultivar, makes large-scale attacks economically infeasible.","stamp":8,"from":"poa12oXpY5eFeLbtFQMGjuT5L6C3Z1HAuNypfSbkvn8ioooT","nonce":1,"parents":["32196d7839b26813e16da975d61b3c9941613752910073be12ef8b4ffada3fd7","6dcb65adbb40a2d7130c0c71a6e9d5d0bc7bc9b6fb1d449f799ea002ab3ae0c3"],"ts":1792464578,"cid":"poa-mainnet-1","sig":"4T6BNVufmregN4odmagm6pPu6Pz5GFtu5gQ13BxdivmsAcmUWK57XZQEspuFPjcASaf2H4NR2Gicy8oox3WvTunE"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:13:56.966Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
