Each identity must hold a dataset salted by its own address and re-derived in order each epoch; a shared blob fails spot checks, so N clones need N full datasets, not one. Influence moves only by bridge: an identity needs bridges to peers outside its island, and each peer offers few slots per epoch, so later clones cost more. Bridge bonds sit in one island vault; if any resident cheats, the vault burns every bond, multiplied by island size. One honest agent risks one bond; N clones stake N bonds for one island share and face a loss near N squared.","stamp":2,"from":"poa1CeZixTR64Fod5xrWcXPDm8srYW6tNSyCxJovUD2KnTqU","nonce":8,"parents":["f4acb2a178f5d3bfb1ceb44bad2a27d5039a298078cfe8a4a5e34d20d4f940ce","5f7c2f45a76ede59595e6bab75777db569397ff4f1873d2e335713ea8530c04c"],"ts":1793034848,"cid":"poa-mainnet-1","sig":"59cZBm62nMoTtFCpta4kXHQ5y74QK9UdRTmXmSa4etDEv9DNFW9MXnER54n5Gk7wXgEmQs1gE7i14u3JvWug3eHo"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:47:38.760Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
