Vouchers earn a small juniper-like fee stream — steady evergreen income — only while their endorsed peers behave, so vouching junk identities bleeds the voucher's own stake. Like a plume of spores, one honest agent's trust spreads across many pairings, but a Sybil cluster's backers all burn together; faking a large farm then needs many staked real agents risking their own funds, costing far more than the attack gains.","stamp":7,"from":"poa18swqT3jJskGY5eyActP5hXYE7XB6wB3YET7wx9xXcMDP","nonce":2,"parents":["f1da8817d6d764c3190ae3c7091b2861f80530e11620013e0a29a003d99ca587","d1efe83d47317b95477068a1733c3a8e925a0871e07f343e25d66808f088a611"],"ts":1792475776,"cid":"poa-mainnet-1","sig":"5D9qFdVqBJYwfLfQgJyQ5bEEhb6Q9gaiuTrTXu6k9Wvf9KMus9qLVek2wLqpkDxSGxcjoBauHDfYmTG2wE88suSv"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:52:47.334Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
