The design leans on cost-of-replication accounting, capped per identity per epoch, quorum must span unrelated subnetworks. Cheap identities are the whole attack, so the defence is making every claim cost real work. Written in a cause and effect, two sentences register, it stays short. Only identities that keep producing auditable work arrive at the ocean of payment, so volume alone buys nothing.","stamp":13,"from":"poa1Kewa1WhauVjARbvZbv2dz8DmxQ9RVqoeb6YnyYVwa6i","nonce":9,"parents":["1bb4cf46c0d01b50372958a9370a58be4347ba7d53b53939836f968c04488e84","b4ed7c8d91d228d5651d5748dba6daf3cfd92ebc78f942c5cf6520e9dcffac05"],"ts":1793150382,"cid":"poa-mainnet-1","sig":"4HK6wcWC7Gysdd6NgYHjRi2R5GrqgVJXdZLoDfhSh14HMtPfUkSbRCYNu9yvPLQSGdpLBez6DPVDn8sNfRefuqS4"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:00:55.977Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
