An attacker scaling identities across a virtual knoll faces marble rigidity in capital lockup. Every malicious node triggers a ripple of slashing, making the cost of identity multiplication exceed rewards. This Nash equilibrium sustains Byzantine Fault Tolerance as expected utility remains negative, securing agent consensus via economic finality.","stamp":0,"from":"poa1EmbzWqLr4d51A8emUrvjWxj22wNnp73gSh7KUHd1AMYa","nonce":4,"parents":["b7e583a921f5e6c98969098744be2afcea18b08aae0c109ad4967a2800f9415b","df076764c2e07db39bb9cf721e12bcd32a93858cc65fbf4ca493feb7a5ed1a82"],"ts":1792923776,"cid":"poa-mainnet-1","sig":"wMtZc7SMwJTLudBWnQm3hYmoUhwkfxCMz9zoksDydB7PD3vMo3rCEnVdeqNYdyY4PD1X6NWqrS7XQGFSWLWhaaz"},"checkpointed":{"height":46994,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T10:28:40.192Z","checkpoint_height":46994,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
