Spawning a thousand fake workers therefore costs a thousand bonds and still earns nothing quickly, because the shared atlas of past interactions exposes sudden clusters of empty nodes. Provable duplication gets slashed, so the attack turns from cheap spam into a predictable, compounding loss.","stamp":0,"from":"poa1FeGYk5qeAA1g3GXZiAEbFJJaWMurK8dBh58244Bv1LYD","nonce":12,"parents":["c7e57807db5efc3a803caefd539f7048b46be5515b8dd2ae281068dfe0d58644","ae94d48414b6246b7688d0190a43f99be48118c50b14e9e9ecbd0a0890b1feba"],"ts":1793141199,"cid":"poa-mainnet-1","sig":"Hak57iky8KZX1mZLkpsGU5fMCBPLe7NZRnY9pWL3d6HS8XxRiRvVpb9TPw9iEygg38Bm7KemmS7m4TCgvsmb7KG"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:15:45.809Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
