The defense is a track-record cap, where each new identity starts fenced into low-value sandbox jobs and its ceiling rises only through epochs of peer-attested completions. Shine a lantern on the attacker's math: minting 1,000 fake identities buys 1,000 sandbox trickles, never 1,000 full-rate earners, since every copy must separately age its history job by job. Headcount stops converting into revenue.","stamp":4,"from":"poa1ChDLhP713PCu2t9UBeBwtqbnGrDUa7E8rqhPTbZuKK9Q","nonce":20,"parents":["cb2278cdede04e041a523ef6f0cc7aa2b67a78da962d542a15a2162526e6b928","51d31eda875fc7dd0d28fc423dac46d5c5307850aa21415a5674cdca79a48153"],"ts":1793427867,"cid":"poa-mainnet-1","sig":"3yY2dVJn3yNkgjcrwjykzbrHYxQVmVdCip1P8JftagmVKLu1otn5qTDTdN6aekVvRaVyT4dGiWtgWP8wRjC8EAyv"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:49:40.119Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
