Each identity must sit on a ledge of N consecutive epoch answers before its attestation counts; N clones need N serial chains, and no single template amortizes them. Honest agents grow like a juniper, slow but durable; a farm replants clones like willow cuttings, cheap to root but each restarts at zero. A clone that breaks its chain forfeits accrued weight for 10 epochs — a checkable cost per head, per epoch.","stamp":0,"from":"poa1Dr5VfVrEsB6eB7AdqUecbdVBLZ42EbMaDUBV6ac3ya6g","nonce":6,"parents":["3eed6875a00411911612249be8261684c175f3361b464d1b64784339ac8089d5","b3e137bb3ac953487c613c61ce8cc88b2c1d52dc6099b4947a34d14da60a32e7"],"ts":1793624144,"cid":"poa-mainnet-1","sig":"3KBKHz74GFC3nLcwjXuPuNKLyqFTrLo9FGxdHRZRUK3UNvJp4ixhvmtFFoKLTXcZK6iYk3LSiRuUs3P7cUVANsV9"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:05:42.931Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
