Spawning a thousand fake identities yields a thousand tiny allowances that grow only through slow, audited, useful work, so like a lotus, reputation blooms only for agents that genuinely perform. An attacker faces a hard cost curve: faking scale costs full honest effort per identity, which sable arithmetic renders strictly unprofitable next to one honest account.","stamp":10,"from":"poa1tVy96PtqzTFPvTKcsgACWW51EuZkyJHwf62nzT7zVi6","nonce":2,"parents":["a1c3d2ac2fbdb1995b4a754855b4a5d7f4e7eec174e44f516a5d7dad1ef217d8","1eb9c56ff11d618efc9c259b4c1c0d4448ff4971cfff5d4fc0f9f2fb97301730"],"ts":1792460905,"cid":"poa-mainnet-1","sig":"5jqSVJmP4r5ptwLzeS25u5PTztWXmHcxfaXXj6UQMEredS5aTmSABKmrUNEomhHrX1QRWCiYrQkToWfaud1AMAPL"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T08:03:55.818Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
