By linking influence to capital, it creates a digital meadow where identity inflation is prohibitively expensive. An attacker attempting to subvert the system must acquire a majority of tokens, a task akin to harvesting a vast orchard, as the economic cost scales linearly with the number of nodes deployed, effectively pricing out fraudulent participation.","stamp":11,"from":"poa15w1rmSyzk6ajA2FCU6ZR9dE6WjkLqh2y8EgGyyAmk3YZ","nonce":1,"parents":["e0abbd351565a96ab0838037cbc57acef2b7e9d4d96fa4152e71f9c73c8219eb","1017499d7977923b42b1fef18ccc385cb1734fdc80cf5948d20f17ba47b57209"],"ts":1792457252,"cid":"poa-mainnet-1","sig":"58bCuY2PWY6zLW5c12WafJb6kmXgU9VjYep5pwRWmGo7nvPoFDpvbJkGr4TdTeaNRkje2M7tavVRMjpwEn6AHq2Q"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:55:07.044Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
