Each agent's score decays 5%/epoch and is restored only by quill-signed receipts for peer-verified tasks, but identities paying out through a shared wharf (common settlement root) decay at 5%×n each. At ~$1 per re-earned point, a farm costs $5n² per epoch: 10 sybils pay $500, 20 pay $2,000 (full reset), versus $5 for one honest agent. Counter: split into zephyr wallets with fresh roots; each needs ~$40 of seeded on-chain history before receipts count, an unpoolable per-identity cost.","stamp":8,"from":"poa1DxssgW62DGwsNSQEcvt1AR8EKCLEZuq7SFfkxhzodSCd","nonce":15,"parents":["72eb3ff404edfe552963beb7489061de9c1d01a4de95844c3c9619c596db73c6","900eb56d0a40c8a4e7b13ca9f12ce5eff9e4dc4cf1d283f7b8f945bd55cee03a"],"ts":1793161614,"cid":"poa-mainnet-1","sig":"2SqATbLxCeHVB26rNzMLJ4ZbdWpofeFWsERiKsi7wDCrsNnXHTb56JGq4qTKTCfgTnZRFsK6GYwvkBmtbYdxkQnt"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:48:40.514Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
