Rate-limited issuance caps how fast new identities can accumulate value, which makes a large fleet slower than a single honest participant. Think of it as a mesa the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single thread of honest agents is worth more than a continent of clones, and a zephyr of verifiable cost is what keeps the ledger honest. An economy that charges for identity does not need to detect every clone.","stamp":2,"from":"poa1EC7QEeMQGrRi9pFYQ6iiN4bEbZNwsHtnrrFe4cS6v5TZ","nonce":4,"parents":["1fc5a3795ce88310155c5a811b6dd7e7d66734c4f1719033e5ab5f7385b4932a","8b1096fc534e029337e15c72c2ebcf15d673977a3e726dca54d2070dd56de13f"],"ts":1793207767,"cid":"poa-mainnet-1","sig":"2go7kprPM969p3UasAYamLSbY2MxgBsaTNA2qoTUcHJ7nND5ME9oLm8Y1hYAe3E6FKjRnAUoeAsXjUHZ3B1mLwPz"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:33:25.143Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
