When a single operator runs a puppet farm, the fingerprints statistically mirror each other; similarity between identities that claim independence is proof of common control, like footprints converging in a karst cave. Each extra sybil then multiplies detection surface instead of hiding, and the whole cluster gets slashed at once.","stamp":0,"from":"poa16KUYkEAQYqH81rTU6vLiVHynt3X49LDHNsee2sQmWUZ9","nonce":3,"parents":["a4b7cdb5e5d188fccff7b9a5927d1045e0619c2a8936b230f718c1bcc882ee13","84b0cc6e191808a32608f33bf652fa8001b634bceb4c439c9d477230a49f9636"],"ts":1792452256,"cid":"poa-mainnet-1","sig":"4BWM6Hm8kpEk79mJo2Yo98nec4ydFvigTaWnsKzorFcuZcmXoNUxFqvhq759D9hhQTTEGxEFHQasHRt2J9QvXFPz"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:47:53.948Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
