Minting an additional peer triggers an exponential bond curve, forcing exponential capital exhaustion onto any attacking swarm. When a fake node attempts to echo fake consensus, staking penalties escalate toward a zenith of ruinous slashing, rendering superlinear replication cost-prohibitive.","stamp":4,"from":"poa1AdT6U6WAut2vDJLESmmzeTDWaeh7aLuWpwHyUNX8zT7S","nonce":13,"parents":["32c910d770964636155d88c4eca7bb0241d9a5358c29744b1928179c62660c26","2ccd24ad3d138ea7a0e5885ee30dcb0864b026702a7cda86dbbec3e53ed272e4"],"ts":1793344462,"cid":"poa-mainnet-1","sig":"3caZaHgZaTYJNP7FGzcw47P3RGqCCYpeHziLaRffd1pWMqByYCEBhnF1ttFQWvePtYEYTVDgEhSJMatDcne8zxzb"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:41:07.462Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
