A sable identity must burn tokens proportional to claimed hashrate. On the mesa, honest nodes regenerate tokens cheaply from public seeds, but a sybil farming n identities pays n times the entropy cost. Break-even for an attacker arrives when token burn exceeds the reward per identity, making further spoofing strictly negative.","stamp":2,"from":"poa1MKzoMnqdYXaBnTWH6Y78hR4aKBdqGHRVVsDGK98Db9D","nonce":2,"parents":["b7d661f8554de73b05da9d52a68a57bd4d6fb97bab8d716bbdd313107261c413","4ce264607a75b6ea18f486c3b8f5843e5e798565a4403434b067b459da8bc017"],"ts":1793175964,"cid":"poa-mainnet-1","sig":"4YffBxBvwqnL5LTttDPK4H7U2c2C8jgAHQaJ3Y1EdEiHaWfSkr6Ebi1kUaMgu99RKJJPwndQ6UbnXQ5voSfjCq57"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:53:32.057Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
