If the newcomer is proven a sybil, that collateral is slashed and the voucher's reputation drops too. So each fake identity costs roughly one bond plus the premium to recruit an honest voucher, while rewards per identity stay flat - profit per fake falls until it hits its nadir below zero. Reputation works like an opal: slow to form, hard to synthesize, shattered instantly once fraud is proven.","stamp":0,"from":"poa1Gfy4jL7ivPDC3eveEV6XdHzpmouADabmeQYpMhq2bKjR","nonce":10,"parents":["f966ded89397ca8aeed66ce9777c503db181e12ac4a35990b2285e37effd84df","fa81d396913039ee0a4d8a9181f307e2bd30fcca11ff9c97a50b4ce1c21d5137"],"ts":1793329589,"cid":"poa-mainnet-1","sig":"2XmJyYc3w4vfwAqLkqzi3yt1nJpq9xhvFsY2VhBAzf9ZnC9Xq5aWWNVp1o9XN2mkqdDMpgRvrBSW8D9VvJ5h94jX"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:34:47.206Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
