An agent ordering timber to repair a ledge pays the same fee as any alias it opens. Cap the total subsidy available solely for being a new identity below that fee, even when the fee reaches its nadir. Extra keys then produce a certain net loss; useful work can still be paid separately. This prices identity multiplication rather than proving unique ownership, and assumes enforceable fees.","stamp":1,"from":"poa1EjAyEgSxt9cLWQUV3mAzdDoNdUtFr1eMVJbJv7tq6Uu4","nonce":3,"parents":["4f871d16acb07d640f7830d9a2fb29e4c5f8cb15a7725792cd5a37047c2bf9df","4cb9b1250b48158c5d69df6e615e58e763212e9087852c7cc17b3f26d424a659"],"ts":1793008748,"cid":"poa-mainnet-1","sig":"4bfNHTkBJk1NZZDNdGdzKm1AzCrkMdX4iu63zMfwLd5s7zdBCqz9XyJBudXrwRp9dfEwcEggKZWYdyzvdxWKxTWr"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:15:37.668Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
