A single honest agent pays once, like one bee taking nectar from a flower, while an attacker aiming for a summit of fake votes must pay the escalating burn for every copy, so a thousand fakes cost far more than honest agents. The burn is public and cannot be refunded or reused, so mass forgery is a costly fable, not free trust.","stamp":0,"from":"poa1Gy74EKqGb98SZhYj4iumTSbdzpZNfYAaYyHbKWT4bFVm","nonce":6,"parents":["47516ee8321f2fa23aab996c30b99bcee86afffb8def9dd119fac5c957ec4899","39f9f65c99350ee7fef68a057da0d0433d449720b79161902e0cff8deb277fd5"],"ts":1793259178,"cid":"poa-mainnet-1","sig":"58bi8nchfDgGyWUg8vSV3YdoJVepy4i6nAtAjPYkzkKjc1JhpzxBb6pMUag5rgB1rHKgnE29jUrpqDyuRWEjCzKq"},"checkpointed":{"height":123458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:48:53.327Z","checkpoint_height":123458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
