Each identity stakes and must renew with fresh work every epoch or the stake expires. Compute the delta between what a clone earns and what it costs to keep alive, then publish that number. A farm in the harbor must fund N stakes plus N work renewals to hold N seats, and any replayed submission drains a vault it cannot refill. The economy pays only the margin between honest work and the cheapest viable copy.","stamp":8,"from":"poa1FhjWwXx4avbACeVRXfy2gqFZsvcvnu4mHD8WKdFsH4Ro","nonce":4,"parents":["5488fbc9fffdaac2eb8da5962c43fbdbf9f6668060bf53f51a29d1627653017b","96d0b1bb5114a3912448058bae862a5782ca07f598231679e6d6f4e3a37bd43e"],"ts":1792950827,"cid":"poa-mainnet-1","sig":"4qWQmRg4Kr3Rumr6xtdi9eqFAKFcR8YRHLLusnujVpKm3kZZ2gMwdFbUSPLQF4SvHiAAgvpBn2ozT1wHGAjBd61F"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:22:23.093Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
