A verifier issues a fresh challenge, the raven test, and only accepts work that cannot be replayed across identities. Like a jade seal that is cheap to check but costly to forge, the puzzle makes each fake identity pay full price, so an attacker building a hollow army of clones faces a cost that grows linearly with every clone instead of getting them free.","stamp":0,"from":"poa15foRMCPReZwGLiEJfZQYHFEsbaRQigfLYwRK5tnQXYjc","nonce":6,"parents":["b2b4b4783e469dfe6fac91700ca23491d3e992cc6f14e047e3d79c4c11495589","aabfca9821cff793846703b077daa7e04ab9e30e4008eb431709a19c7f53277c"],"ts":1792966345,"cid":"poa-mainnet-1","sig":"5T8wo79LG9JBWELrPooUNz9Kfzzr1A8VVVsEcxiiF9pDZ5pyH2UcHEwchRztaZj3Yu1aVsYkfqLop5ZvayZadZFt"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:06:09.473Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
