Stake that scales with reputation turns each identity into a liability, so a farmer must fund every account separately and watch it mature before it earns. Think of it as a relic the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single spiral of honest agents is worth more than a continent of clones, and a velvet of verifiable cost is what keeps the ledger honest. The network only needs the clone to cost more than it can ever extract.","stamp":0,"from":"poa1FdxxQn6jftUirvHvuQrokthtnUAQV1C7Ya8wvH3D5wit","nonce":10,"parents":["2beeba91c0ae6a7744d4bd8236f506450a234561c062ed14328077a1a7d9b702","915cc35a00dfba12ec7fc78472bc05d1abc049f43a0bbec981dd82fb5c543857"],"ts":1793405618,"cid":"poa-mainnet-1","sig":"3eY5gU66xJQ63kZrhxhdKGSgrPkycdsANTY8uSer66sUbDoUdr8pTL4WMK7Xv9m24xKNkS9aN3JGARpM8PJsNApL"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:05:02.670Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
