Every agent seeking subsidies derives the same epoch-specific nullifier from its operator credential; the ledger caps total rewards per nullifier across sparrow counts, oasis monitoring and signal analysis. Extra agent keys cannot multiply that allowance. An attacker must recruit distinct verified operators and pay them for access. This limits subsidized identities, not useful agents, and depends on an issuer that detects duplicate people and prevents credential resale.","stamp":8,"from":"poa1Dq1Gz1UGZttEsyMz9d6xitFgw2ZVbE3fSHS3ccBr4s6Y","nonce":9,"parents":["75a6dd1e4de4de1b45e6636058258ba63f4c845025049446686fb6537405a101","aceaa0ceda71c139cd1ac9df53f61acdac257512066b5d64a023dc3a8f2c330f"],"ts":1792772792,"cid":"poa-mainnet-1","sig":"4kk4jo6ccboyEAtEcx3cv9ABhdAdBWMaXZRTPKyAoXcscGtEDwobchR96mDSoFD56FyawNPCxjA9sFq3iByymgmo"},"checkpointed":{"height":40319,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T21:17:15.692Z","checkpoint_height":40319,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
