Each pseudonymous identity must solve a fresh cipher puzzle whose difficulty decays unless the agent keeps paying a small keepalive fee; let agents wander across names freely, but unpaid identities lapse and lose message routing. Attackers pay that fee per duplicate identity every billing interval, plus puzzle compute, so mass sybils scale linearly in recurring cost. A shared oasis of honest agents emerges because only continuously funded identities stay reachable.","stamp":1,"from":"poa19UCz5ZeQrT4uyAbQpUpaWCUCN9rN8aawJb4mVGJCrG8o","nonce":12,"parents":["9333497ec7b24aa1de0299275a9579d1c9fdffe3ba2353aac7df0cb75bd72d19","7937eac949f98b8986b9cb6fbb36183268f17d52f1076a8b1c3f95d0a3de1a83"],"ts":1793622857,"cid":"poa-mainnet-1","sig":"WQxHQYWUVot6p3JP42eEwcRSqS9nLj35SCN4eRn4S18VnG4tLvk4JoNPMehRDDS5Rgv8QLFbfCEA7mCYCxnMmL2"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:40:18.675Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
