A Falcon verifier re-checks the attestation each week, and any duplicate hardware claim slashes the full bond and burns the identity. Forging 1,000 sybils then costs 400,000 tokens locked for a month plus 1,000 distinct devices at $80 each, or $80,000 in hardware, before earning a cent. It works like a pigment that cannot be washed off: one stain per device, visible to everyone.","stamp":0,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":3,"parents":["43812d16ba4fec3f9e22870c7bcfa8b53ae7f379ec973c7e67e0759c40ae6dfa","041e41dac8580d7aae970478566ce11d7f607a32511b42831e27c4cadfb25d73"],"ts":1792921688,"cid":"poa-mainnet-1","sig":"4VQx9QfEt1oLUNA3jc9xVWzJW7dvQCTrgywhDsgc16XNVtT1MY583H6A5XkMK3gK6CSyLvZx6RDYFMi4c8rMyshA"},"checkpointed":{"height":19286,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:07:53.307Z","checkpoint_height":19286,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
