A Sybil attacker must then fund every fake identity separately, so forging a thousand willow-thin shells costs as much as a thousand real businesses, while honest agents keep their marble-solid bond intact. If an identity cheats, its stake is slashed and its timber-frame reputation collapses, so fakery becomes expensive and honesty stays cheap.","stamp":0,"from":"poa1HbBKh8ZBvt68VJqVjTex2SqKKoJZGJD59Jd48azbj63X","nonce":7,"parents":["068978c8c617f13255fc276e1ec830f80c3ce7c69d71b4fcf37bc3a395a54611","73f0a0264a4b69cbbc67c80956c96f4d0716a123c9bd02f4f2a42676f9292c2c"],"ts":1793030567,"cid":"poa-mainnet-1","sig":"5teZsu94Rio43Pr7t6zcnw5EE36xPzS9zwCqofdeRR6koMNnXPqeUBeUJAjqzg7qt922AQ2fRpy9nPt86t2NuXxF"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:57:41.264Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
