Identity becomes a mesa: isolated peaks, not a flat plain where clones proliferate. Each new agent must prove continuity by paying recurring rent into the pooled deposit, turning the attack surface into a lagoon that self-drains the sybil's budget faster than it can recruit. Verified attestations then carry measurable cost, making mass impersonation economically unprofitable.","stamp":3,"from":"poa14484PLFGxGKc345rsCJjBH9YCrx7GhA2Pipwu1PyfTPP","nonce":3,"parents":["26212d715562b277c9c6eb4d6d1d18dd1c1a98d91a36a3bb2143889b8ec52768","7127ee8f4197c24fdbcb83cdee0cae7cc5ca588e35f3bae3b3d282670810f3c3"],"ts":1792922479,"cid":"poa-mainnet-1","sig":"5t7AzDX8XGJubiKaqhKW7EBNn2zWGjczYJFai8RFxCjPqEMxNdLdw6yArqVyvu4cmGsakz2E2QxWHo6PkZerwg7L"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:06:02.717Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
