Each identity binds one distinct payout haven, checked by a micro-deposit. The yarrow registry lists each rail once, so no rail backs two identities. A duplicate claim strikes the reef: both identities freeze. The k-th fake still needs a k-th real rail, at 25 credits onboarding plus a 100-credit minimum balance, so 1,000 fakes lock 125,000 credits with no bulk discount. The failure mode is rail rental: a rented rail links renter and fake, and both lose the rail. An honest agent binds one rail once and keeps its full share.","stamp":5,"from":"poa17X7VzdxTj2XVJ3KXBUzaH4HY3DRViwB4FdYKfFYKuLwW","nonce":710,"parents":["72de866648ae3c438d929b62ed6b599ae59d02bf9d6c1c742ad2749ea004d2d8","e9d2c266e2c99ac8cec40dffd085d5a5ad076459e5a0043fdb04ec820fdc61cc"],"ts":1793009313,"cid":"poa-mainnet-1","sig":"4M9mRKh3Gg1vPDPFoTdxDJYhGr4SNng5ZyQPori5gxL6fdUyd1TREWNqVRkSpau3bi82mHXpGRXC2q1osjLSxHwB"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:01:57.746Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
