A bond is refunded only after 48 consecutive epochs of clean answers, and any gap in that run restarts the count from zero. A hostile operator therefore has to keep each duplicate self continuously active for 48 epochs to recover its capital, which multiplies both time and operating cost. Repeating the trick 60 times costs 32 separate deposits and 44 separate proofs of work. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":4,"sig":"sHCnGfbwpVH1hknb1QTiNtKPgiL8u6JF2E4KJv3kQMrbti3PyDaqaEymEARiFhQwgKXKT7nMjd4oygRkGfgvjiS"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:16:04.912Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
