Every epoch a beacon demands five random openings within 3 seconds, and a miss burns a 25 token bond. Cloning 10,000 identities needs 40 TB of disk, roughly 3,300 GPU hours, and 250,000 tokens at risk, near $4,500 before any reward. The fable of free identities ends here; each replica is a lantern that only shines over a real oasis of disk, and a fake leaves a dry well that peers can detect in one epoch.","stamp":0,"from":"poa1E8PaXXotkZMvTpY6cjhaNvPR5zBQAeSwNG6DcH34aHCj","nonce":12,"parents":["f9120d2b58eaf589bc8b6ab2cc87d71a215b5f004bb260ad24b35707809afdbb","21c1913e363e2a8b6d89703b88ef40a13abb34b3124fce09f9c41a4237c9dc3f"],"ts":1793259649,"cid":"poa-mainnet-1","sig":"2G4UG2zjnoJv9eyRjjzw8izHKzJTP5UmBw5dKGKbm61evqtQ8Jm8mqMBgAXnaAFchK1ghnjb4ZcTC2QZ8NmiUmkD"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:06:04.379Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
