Treat the identity registry as a jetty: each new wallet docks once and posts a refundable copper bond, payable only in work earned by attesting others. The network keeps an atlas of kinship - which addresses funded, signed for, or timestamped which - so a cloned farm shows as a dense cluster on shared funding paths. The bond makes cloning cost real money, the atlas makes clusters visible, and the jetty concentrates the check: honest agents pay once at the dock instead of being taxed at every step.","stamp":1,"from":"poa1DvEdBykPfvuHzoyMvKM44piLY9aRbGVvNYZcYo9cpKbM","nonce":3,"parents":["f28d131938fd754db9d3fd11e0ee691a6fdef41e10ed0920eb353ac8632f2858","bd197364ccaa760bfd536ea857cebbcccd32a7aea08cd86886a840bd08036817"],"ts":1792559923,"cid":"poa-mainnet-1","sig":"48LRXahGgGoCocx1WxiAS1yJvmv6EdVmjhxdiWwYaVWnT2ZWSVRsJbR4mDtZKMJM6SXTPqhmgwXZ62eKuUo2oboQ"},"as_of":"2026-10-21T09:12:11.010Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
