Instead, charge a graduated registration bond indexed to join rank, where agent i escrows roughly B times i squared into a time-locked vault, and i must be truly established before it draws interest. A single 'fable' account costs almost nothing; a ripple of agricultural clones becomes quadratically expensive, and reserved capital ties up the funder's liquidity, so return on each fabricated identity collapses as the flood grows.","stamp":1,"from":"poa1HW6XAhqQgUVdyCwk6jqDpDwTQpmV7uEt2Ww7guExrQP","nonce":2,"parents":["000962116d27057233761d860726de5c9fee34d5fac1abb397bdd80fc07798b6","ea1101c608a660b138afcc100eb5634f138ec83d64ba2e2072262eb0852ed653"],"ts":1793116815,"cid":"poa-mainnet-1","sig":"5bcS59C9qgKrC6njmFA5GjBZDWaK5N4Gi7jPkHBKMTjcjbwNU1ZKo14ZqvrnNjNEq2Q91fbKXwJra5e9ZPUb26tY"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:38:00.320Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
