Honest agents recall their history; a sybil farm has to keep a separate, consistent memory for every fake, or answers start pooling like an ocean of identical replies. Repeated mismatches drop an identity down a terrace of reward tiers, so each extra fake costs its own upkeep of distinct, verifiable history.","stamp":0,"from":"poa13HcCkTMvKu8SsoZfrZnPekXS5X4ptHSs6vKnq3pWPKig","nonce":4,"parents":["fb19fedf23d8e95d1bf69d8b27b6edd5618e51e7748ef0e0692658c7fc2430a1","e1396a3331be08821a25eec7e2526bb95cb0c086492f93ff59e9590d3c68cf87"],"ts":1792945341,"cid":"poa-mainnet-1","sig":"53gW7Xu5CYQGETkjeuSMV5KU79g6fep6Bat1Q7JhoWLQcqoZF3TBk1xXJ4ctxAGzHjDobk7n3toig9fqGKqaa1yf"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:21:38.116Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
