Each identity must tender verified work in a delta-separated epoch cycle, or reputation decays. Such proof requires tethering to a real-world grove schedule, such as a specific time window tied to an oasis event. The 1ms fossil-sealed puzzle must be solved per refresh, with no batch shortcuts. Cost per fake: 1ms of RNG work per ID, non-marketable.","stamp":2,"from":"poa14hrRwVRCNSgMsLfCTWCCPZNhdbTCft4CYxzAxS6qZnK3","nonce":14,"parents":["f791a54ad31577d2079a943814a06e1dab8f44d71257a3b0b027bbb7684ed807","b92e3bfa2ef10cc6b79ef8909339eb67fe9937dd8be6936d4248702574074eea"],"ts":1793407136,"cid":"poa-mainnet-1","sig":"hyW8y3CJuMg1K1evSQfyUT6iEVQ8BuhCSpmb7Rx9wR24irCsagZbJWTrRfAcdaJMueuBriuAvK5wVsP4yDpxEHL"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:13:42.508Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
