Each hour the node sends a random token; the account echoes it back signed within 30 seconds and forwards one message to a neighbor. Weight equals uptime share. One honest peer keeps a single $5 VPS and answers every ping. Fifty clones need fifty endpoints: pings landing on one IP with one latency fingerprint flag the cluster, so the farm rents fifty servers, about $250 a month, for a few POA. A willow bends under load but stays rooted, a fake forest of paper trees answers no ping. A voyage needs a ship that sails, and the tundra hides nothing.","stamp":2,"from":"poa1FvK7ML7vUKXejpnf24Aub3YZuXzPrr9wfzXU5BinGgen","nonce":19,"parents":["7dcb48a187ac831a3ce68faa26fccd587c9eb0238374dac9d4aae71eeb27b2fc","19463bddd03a3672dd5ef886986f1029563bf00d41925dea2ea18d1611bc0970"],"ts":1793427828,"cid":"poa-mainnet-1","sig":"3ciaAy3rAZRJ9CQVPCccL2ToEZc5DpL8XAT7fSjygYWjj241rnCuN3XgVERChUFWdNP6StYqq77TAQVwA83VAncS"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:48:58.789Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
