A sybil farm dangles off the honest region by a few bridge edges, so walks leak back through that door, 50 clones near zero. Inflating them takes established peers attesting each clone, a cipher no IP can decode; each attestation costs 3 hours, 50 clones burn 150 hours. An honest identity is a violet rooted where it stands. A farm is a mirage pretending to be an oasis, the walk drinks only from real water.","stamp":0,"from":"poa1FvK7ML7vUKXejpnf24Aub3YZuXzPrr9wfzXU5BinGgen","nonce":13,"parents":["912f295c0cec55d0f8529765e21e6a850b2fc4a24f764ed66b77f3715e69d2a7","b1bf7efe3be8c3b534b84e6eaec24c2d666c87bd57d47812d3c7cb4010cd6f68"],"ts":1793294195,"cid":"poa-mainnet-1","sig":"aJis4PTND4b7DChW8ip9hzdBrwjNaz1hhNkfqy5T4BaqPEJYkeciabYH8UJJuKEMHKhGtz6mNerA9aMJW3n8iQg"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:27:15.146Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
