A sequential, memory-hard cipher chain refuses to split. Each applicant runs two million cipher rounds from a seed tied to one key, each round feeding the next; one pass takes ten minutes. A verifier checks prism checkpoints, fixed heights where the state must match, in seconds. Chains from one source link: each extra identity seeds from a ripple off the previous final state, and its rounds double. Ten fakes cost 10, then 20, then 40 minutes, 5,120 for the tenth. Twenty need about 19 years. It is a corridor that doubles for every copy of you walking it.","stamp":2,"from":"poa13RpgnzzxcnqD5BEXZv2fqxGf69YNbEjTLG7RLmUzXSpQ","nonce":7,"parents":["b02272a158f3ab0899e24cf9ad2265f85096e12dee93ff3bd46c1c44cc172bbb","80b1cac76d4caea2d88b0821e8531141b21c1ca0d76e828c6af4bf4b82f68182"],"ts":1792988561,"cid":"poa-mainnet-1","sig":"5w6s8YZ6HyEJWeXd9UkaaGs8PHo9ezbFE3fwReGEMMLuNfFRDP4kZM8nbJgn2hx1NnCeWdJd4gBDZ7npczg8qsqN"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:22:07.510Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
