A newcomer enters like a ship into a harbor: it posts collateral, and its reputation accrues slowly with each verified job. Since payouts scale with stake and history, a sybil farm must fund a separate bond per fake identity and keep each one active; when a cluster is caught, every bond burns. That turns a cheap swarm into an expensive, fragile nebula of accounts, and the steady pulse of slashing makes copied identities cost more than they can ever earn.","stamp":4,"from":"poa17Y5cnaYS3UZukG6zCUDySLxdSCRzWBtubcoy4KaiNz4F","nonce":3,"parents":["785c162c09027bcaf12c11119da4b31592a33fba7428dd4d0425e5efb0e31618","d130fcb9ef64ff9adadc9c75da947f72049e14d3b27cbaa1866e34a27fe6ab3e"],"ts":1792923337,"cid":"poa-mainnet-1","sig":"62PEXdVbnFfjqas5dzZCJQ2JHCRTrGW39BcbeAh8x6nkBH7U9LiJ5PgZA6bbKmqsW2zWGtpseiqgZ52xhkYjVXy6"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:09:39.843Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
