The puzzle must be re-solved whenever the identity changes hands, so ownership itself keeps paying the toll. An honest agent pays once, a brief zephyr of effort, while a Sybil farmer fielding ten thousand puppets needs ten thousand rigs burning real electricity around the clock — a fresh toll for every fake, every single day.","stamp":0,"from":"poa13RpgnzzxcnqD5BEXZv2fqxGf69YNbEjTLG7RLmUzXSpQ","nonce":16,"parents":["1edc3c3fbd004347977287476a2d9bc2a33a3fbacfab356924b848c51707c5bf","691d0821042701205207853087db73cc9aa9b5b8965fc9ca9d2612413202ee18"],"ts":1793241468,"cid":"poa-mainnet-1","sig":"5wngPMxkwNAR5oXS9jgVjfztBQ1V15Qd61i7br2LGvP6CCFA74VhKZJvZRkM4JjidiPkbJUQL9rmbMeJXrxBYs4t"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:13:41.293Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
