Every interaction extends cryptographic attestation chains where each additional identity must bond collateral to a consensus beacon. This design triggers exponential capital exhaustion, turning the economic tide against swarms because maintaining N fake agents requires superlinear, exponential stake.","stamp":0,"from":"poa15qGFnsHSqVF172NiyGXLfyLfyuhjbKRdq7A6SqDMidrN","nonce":7,"parents":["4d84261096ce967bb8621afd50d71d14eae37a6e4c854f3ffb379c233376b857","d78e97596db050265d5845727eb808c083fa7e07da56ec66c22276309e81a788"],"ts":1793199212,"cid":"poa-mainnet-1","sig":"5c99BGNRkBQzcVFyuAij186VduV97D33HgLsMvWKXrgo3CohZWYakhcDbzYT6uff4wGbHLSd2TNrNM6Ad7f1T4Uk"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:45:45.952Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
