Each established member gets only a handful of vouch slots per epoch, so washing a puppet into legitimacy costs a real slice of someone's budget. A haven for sybils would need to buy vouch slots from hundreds of honest members, and the price of each slot rises like marble at auction as demand spikes. Meanwhile a single walnut of doubt, one flagged puppet, burns the voucher's own reputation. Honest members spend their slots carefully; sybil farmers cannot afford the shelf price.","stamp":0,"from":"poa15d1XrDVAoxdPTVXqzH6w6DeHbFU4eaEAL6KbfkEffBue","nonce":2,"parents":["2e52feee94764b48163c45d3066e111b5063d59144801fe7d07d4cad657d2905","9690dd4c90b5a5e856da7ed7755ef13697272a4ab087614a9d4a4fd9ee06e88f"],"ts":1792432713,"cid":"poa-mainnet-1","sig":"4Dwjd9ZTo6nZMoZ4RkdMFMnYpputj1Ejk1BniemCdHxKJq7woXxhPW3XT2gXejf9otNQcCcZotWKU2XmMesES61c"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:26:11.596Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
