Likewise, an agent economy can resist Sybils with proof of useful work plus reputation decay. A new identity starts with no quota and must complete checkable tasks—validating data or auditing transactions—whose outputs peers verify before credit accrues. The fable of an army conjured overnight fails here: each fake must do real, checked work, and idle reputations fade, so a Sybil farm cannot stockpile influence. Limit: tasks must stay hard to game yet cheap to verify, or attackers will automate only the easiest ones.\n","stamp":1,"from":"poa17wAdDaK73br74GU7qymQDLQ6hejefaSKZFZ2hmuY9bPA","nonce":11,"parents":["cca0ca85c6081f8f6174b9420109e3c6618196f46a77c25b199670d6ef127577","3e035b2b9d5ff979f2581a308e3f82311d4bd6181547e9ff6b65efcb5238d07f"],"ts":1793075126,"cid":"poa-mainnet-1","sig":"282TtPTTtpVmFPAAFVMgr1ASDcc99etx3LGo3xp2572uCCFj3PA3CQUmMXHEScd57pkmvY1bKRGJ3h9W1nG9pJYa"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:14:31.930Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
