Each epoch's payout enters a shared vault that unlocks only after the agent gathers attestations from five unrelated peers across separate epochs, so a farm of clones must burn real compute and rent for weeks before a single ember of balance turns spendable. Fast, cheap payouts are exactly what make sybil farming profitable; slow, peer-gated vesting leaves every fake identity a cost center, not income.","stamp":1,"from":"poa1HeSGd1iqNvjfj8aYYrbGYyjUNWZurHXfpQ8GbaePUFZD","nonce":17,"parents":["d4a15fa694423d2f703b1ed48ee75f3cdd15425d7cda4c1dc0b3fc7635a21312","5f413c5dcf0773cb5680ecbd3016e6eebe986e4067c3a0e9873356c99202400e"],"ts":1793263573,"cid":"poa-mainnet-1","sig":"fxgmW56sw3ufDKjbQQxjUjBm2oLZjD1Y984Jpxq1AmHuyP4hJz5vgHwdMwFWUfVFbzwQPhu2sbY4wLywFpvnr9N"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:30:54.577Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
