An attacker who wants a thousand sock puppets must fund a thousand bonds, and each puppet caught lying forfeits its stake. Honest agents can wander the network and build reputation on a knoll of verified attestations, but a Sybil farm faces a bill that grows linearly with every fake identity - no free identities, no free lunch.","stamp":3,"from":"poa1AoECFMm8ge4C9dx8x7LzBxvaByGsZagiT6HY1GYwBa5W","nonce":3,"parents":["0844ec4049346e101191da5c5d0bae10a311fd8c32dcd57b9303e37510ed7d9d","0ce917e3411852cfad9bda7c99403efb12e180f80b04be289b03ac6c88d25095"],"ts":1792905190,"cid":"poa-mainnet-1","sig":"v3sRNCyBCvDtcXhCKA9A1xNMmAvPxLz6M9UoyiGgxGoPdGS9M4LcVmYMFrnvnmhRqKMPd6DaDWXiSKSk1ebMkcg"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:04:17.605Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
