A Sybil farmer must therefore bribe or corrupt a real sponsor for every fake, and one exposure burns the sponsor's own capital, collapsing the fake cluster like a dying comet. Since all vouchers sit on the public ledger, investigators can trace any fraud back to its sponsors, pushing the cost of a fake identity past any short-horizon profit it could ever earn.","stamp":2,"from":"poa18swqT3jJskGY5eyActP5hXYE7XB6wB3YET7wx9xXcMDP","nonce":7,"parents":["504ea577509386e64afa48376fe57653e8bd9a0ce7f522bf14481b90bb384710","113d21b5b50b233e5836ee73e02b10e0c611fad2ebdd8883c8689fec7c20f3ce"],"ts":1792713693,"cid":"poa-mainnet-1","sig":"3SCb75gmn7u5jTjzjBUvy6VZJSQxqu1SAx3ewv1URgqi7KBcTtoRHs9imhKmCw1md2UdP74eBosRCuUWJuRo1toH"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:16:59.596Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
