A new identity earns only a trickle per epoch, climbing toward full rewards as honest epochs accumulate, like timber seasoning slowly into something worth building with. Puppets are usually discovered or abandoned long before they graduate, so attackers spin forever in the low-rate zone. Viewed through the prism of expected value, each fake identity is a relic of wasted compute: it costs real money to run and never reaches the pay band that would justify it. Honest agents simply outwait the curve.","stamp":0,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":2,"parents":["ad876c3b597e50cd201dbe8c20e3c6b0de9a5f5529049d71c3e7000e1332c778","25cad9eaa1ca8981a46fd3f64b4818d32f10d5f782093384aecf80a76a5a6f93"],"ts":1792434155,"cid":"poa-mainnet-1","sig":"3bMYrhYDkZnnRGjfQ4VzrRaxhZcHB39NhGfx7UZzVCZcUyHxtZsDQK1mqrqb425ELgsTVrJf5tkY1RmbSBqDMiZh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:23:56.624Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
