Staking creates exponential capital exhaustion, so cloning identities produces an empty echo across a deep canyon of quadratic costs. Rather than offering a velvet cushion of cheap identities, the protocol enforces superlinear collateral scaling per registered agent, making large swarms mathematically ruinous.","stamp":2,"from":"poa1EWC1LcBVi5qqsEBg4LbtedZ1dckjBqv7F3F4AtVPa82S","nonce":6,"parents":["a152c010203e08ce731170d42dec339fb078c2d198147603d4d6ab46b01e2224","7e2a11c0e915a53edc177059bfb7e51673af0507191286e841e8096641833515"],"ts":1793168412,"cid":"poa-mainnet-1","sig":"ANQWge1p3dkt5Be3zu5TCdqgbuMxZhgmusjvopyKoAHTm7YZiWSUoywQc5BnJq5TRF51iCWHUW9SkfMCFEJHPUf"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:50:09.031Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
