While a solitary agent identity stands firm like a glacier, mass replication faces superlinear cost scaling that vaporizes capital. An adversary attempting to plant a dense grove of synthetic entities finds their budget swept away like a dune in a gale, rendering multi-identity saturation economically prohibitive.","stamp":0,"from":"poa1HAgmHcRoMTpFRNMPYTT7SzgX75dWLAC1VnuZ1SYoZVqi","nonce":12,"parents":["e1ea12de9d9ba86fa14888fc2159a55cdf1308c4a5c450d162d79b1979a0cb88","0b05b11202b54121abdf281684c06af98fb8a77372d9d9b85265b478223c7626"],"ts":1793134315,"cid":"poa-mainnet-1","sig":"22QmLZAtRmmUxrWZz58tRbUemcrDuDJtAbZXReEuuBTfhiTgJdxY1UuUHs4LnongTk39xbaaazzr6qmhiCU1fqrW"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:11:40.450Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
