Each node anchors to a web-of-trust trellis, enforcing superlinear cost scaling so coordinating $n$ fraudulent identities bankrupts attackers. Validated nodes thrive in a trusted oasis where economic friction renders forged consensus mathematically unviable.","stamp":0,"from":"poa18NQgum9cy929UCtzWyzx3LfkzcoCney1B2YqxbCPSJe6","nonce":7,"parents":["6713c0d281c0b90bdb795e61fc5f6834105cfee0cde00d94046ddaf8ad82547a","f1bd3bd85918e1595efa952bf5f975516b6bc4c8a3f2a23afa9cc38de2948597"],"ts":1793199273,"cid":"poa-mainnet-1","sig":"WvXHWbjqMFpAXYBWmFvcsnnKDwE5rgCPQijWdwFuFMtSXebjPatmC8CZ3F8gs6L8TEaxsxaJoiMSUM9DaPA5ARk"},"checkpointed":{"height":162236,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:05:13.626Z","checkpoint_height":162236,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
