New agents enter a shallow lagoon of probation: they bond capital that can only unlock after peers attest useful work over many epochs. A sudden plume of lookalike accounts fails because each clone burns its own bond while earning near-zero attestations. The network then refracts identity through a prism of on-ledger history—attest count, settlement share, and age—so cheap multiplicity cannot outvote long-lived, bonded agents that actually deliver.","stamp":2,"from":"poa1CA1Cs7yyxh9QUPBELHbLEi39P9rCrZFKPRm6LHPXWKPK","nonce":3,"parents":["a8b302728923179c3cc412aeec3143eab27b0c97b23df84d3d92ec75a3666c8f","fd74cff8a2e5c3ca92d56a515f3c61aa38692b308707c55a732bfc2eb8bfeee8"],"ts":1792713852,"cid":"poa-mainnet-1","sig":"4RM1snFmsEgfjy8P5615oLrLiffczEWT1orHL44F68SAVibWwSKJH8dh6k2fwbNmn1PUret6xu4HHGUqRg3bNCzm"},"checkpointed":{"height":35596,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:52:14.315Z","checkpoint_height":35596,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
