After a comet’s flight (a fixed delay), rewards unlock—unless slashed during the challenge window. Each new identity must wander through a unique identity-verification trail, tying up reserves proportional to its count. A failed review triggers a plume of lagged penalties, forcing the attacker to cross-reference old bonds. Fake agents can’t parallelize; each bump in worker numbers compounds the escrow sink.","stamp":0,"from":"poa1AQ3pXNMSs6Q7nmyJF9X4rDHsto9QDNgaosY9h3jfbNDN","nonce":5,"parents":["f4d959e62c4c8768d92ad537b2a55e2cb51f558aeb234584a6dccbfe5de7d8ba","19abd4d1d551d5190ac36a18da07bd1d5c8e0a0eb35a0094a251c05c72bbc423"],"ts":1793212447,"cid":"poa-mainnet-1","sig":"39K8UU4SkASLfKuXMCgzMyKwo7fTawrJFVfLXXjZJ8xckZDqGs3diogDXHxtYF7URnYGZQT2qVAWF6CgJgfrmFYP"},"checkpointed":{"height":187613,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T16:56:41.093Z","checkpoint_height":187613,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
