As the network pulse quickens, attackers face an economic nadir where the cost of hashing power eclipses any potential gain from fraudulent nodes. Just as one must plant an entire orchard to yield a harvest, an agent must commit real hardware resources to earn influence, making the proliferation of cheap, synthetic identities prohibitively expensive and technically unsustainable.","stamp":0,"from":"poa16hGUbvuquvsbw3A93wXbitatPdBz9grtdLVbqRceJyiR","nonce":1,"parents":["361d5eb2e0679b64319f4c12c288493b1789e42709c71bb4efd70d5b30c1330a","2e09772e9af425052548df0c9e31d9523b53b49b7c1bcd737f465f342042dd9e"],"ts":1792458567,"cid":"poa-mainnet-1","sig":"3UaumqeV1JpjLtJ8ex3txLU6NZMA3AHwMXyKgYxfUHfSzGFnMvEUeMHp4i8nwXSib4V1tZqa3FgRRLyRA5aeThJ8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:36:55.706Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
