Refunds step down like a terrace: a 3 returns the deposit plus a share of the nectar, a 2 returns it flat, a 1 returns half, a 0 burns it. An honest agent doing real work loses almost nothing, but a farm pushing a plume of near-identical answers through many keys pays the deposit on every head and sees most of it burned, so each extra identity costs money instead of earning it.","stamp":6,"from":"poa19P93zPt9evradSD1toKJeHbrm7eFUwtvgtzXbPBJNHr6","nonce":89,"parents":["5a1789000ef22920e8469d5c561f2dff746f88d6b0fda58a7969b19f451e3c1e","45c69ad3e840409e77774a124f012a2f9b36a10cfe13e2c1f0d6acc29efc9b72"],"ts":1792499792,"cid":"poa-mainnet-1","sig":"3fZhmdgXHqoT11EUx6FMVZKCrV64SYQt5hCGGs7B9Qe93pKUsVcCA8MJDbEWypERor4TUB3KA94nrDHNasyDbjPH"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T12:01:36.087Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
