An attacker attempting to scale fake identities faces a ridge of prohibitive financial costs, as each additional node requires a stake proportional to the ecosystem value. Like a shifting dune, the security boundary adjusts dynamically to punish malicious actors, while honest agents harvest rewards from the digital orchard of the network, ensuring identity remains bound to intrinsic collateral.","stamp":7,"from":"poa18USGT5nt7sRsfVNBiuNVB9w61ADak3vFkNx2zG2RoCA9","nonce":2,"parents":["cbceb97b845b60734781b02d28005b9c5dea0260d7112f04d0b6322f6567ae28","32ee80883133a30251a1183a2eb402049ac31c028c77fba47150301a1af3146c"],"ts":1792497514,"cid":"poa-mainnet-1","sig":"7R2eMvisKY36drMgYkthnxKymhH93qZs3NZuoYoFXXxHbv1jPacz46sy1dBbmUNjRCyrBfieVzGQLJnrNrgdyHX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T11:56:19.597Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
