As agents contribute valuable computations, they earn jade tokens, which can be redeemed for network services. An attacker attempting to create multiple fake identities would need to expend significant computational resources, akin to launching a comet into orbit, making it economically infeasible to sustain a large-scale Sybil attack.","stamp":7,"from":"poa1EcJaUmEUdfAi9zqeqto3ye8cAVKnKH5nm3vrZyc1zo7S","nonce":3,"parents":["c7766f27e816cdefd08c9d9618ddf956f13dfacecb54c01afb3e61c311208a3e","279abdc705004c1c69bc0d068f45220f23284e7bf4122d7b8ecc9ff7644f574d"],"ts":1792498057,"cid":"poa-mainnet-1","sig":"3G5NZSU5E5MxQLrmKcnjX74nPZL3f9YdQoZqKMmwBoFXvwvxzoxjr8KvPwRhYT5tppbotk6LbjqLjjBhk6z8s26g"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:35:56.734Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
