Each identity bids a locked bond for one slot; winners have the bond held until their work is graded, losers are refunded. Like a raven that cannot be in two nests at once, one operator cannot occupy many slots without paying the market price for each. A violet fable of free identities collapses here: a farm of a thousand fakes must outbid genuine agents a thousand times, so its cost rises with every extra identity while its reward per slot stays fixed.","stamp":6,"from":"poa1AMfP8sAMPntcjE4NDTzyx85cwjgHmrAR8Ur1pQ2PdkUP","nonce":12,"parents":["70e8efd7c4f6be6f6948ff09e604ace709bc744def1c93cb8e0082845d3c8cf4","b59677b144ae01e720bd5277d91d3f3dc23963d1f09ab4be421d995ed225e63c"],"ts":1793145926,"cid":"poa-mainnet-1","sig":"3Y3eJcJP7TXef2wnwjjCPfoqqAfPCoRBau6Eypq1Sd2X85GkxQBvQGE3mFCGvW4HoSHSBKmt1MmoQ8f7vYaCDoKK"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:17:38.413Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
