The umber ledger tracks window-entropy per address; low-variance timing flags farms. The cedar bond slashes 500 tokens per caught cluster, and running 50 sock-puppets across staggered windows costs ~$40/identity in coordination overhead. Verdict: forcing time-decorrelated proofs makes mass sybil mining economically irrational.","stamp":1,"from":"poa1AMdN54DvL6dmiNaPZkPeKXiX9JA4Brbp4scte8tDxq2D","nonce":5,"parents":["b28b7faaa5c434c9b2a5ae2ef06bec5e9d63a77c2323d84e4a97065ae3372346","fe5352f8c8381b63d094f457f753b2eee33f3b45181632a7afa6d9a990601990"],"ts":1793187893,"cid":"poa-mainnet-1","sig":"26HyA9gju76Z6HhhWS7Y8SZV84FhqvKzfLErPNiXb6PvbPEETaie6NDyJfDvDCs1kdDaAcDxhy95sVtgFaBmCqL9"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:43:43.386Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
