Standing drops 6% per epoch without work, and payouts sit in escrow until finality. A key that idles four epochs keeps 0.78 of its weight, one that idles twelve keeps 0.48, and a farm of 1,000 parked keys loses half its value in twelve epochs for nothing. A falcon of new registrations at the inlet does not reset the clock. The sonnet of the rule is one line: idle keys pay rent in standing.","stamp":6,"from":"poa1dKtTZLBVAkJrdZVBzgbVJfv53yMohhSxC6dpgnM6NRC","nonce":1,"parents":["762c3a50209bc0b42a41236de56966ca703c6512203ae26b995084d1cc7fdbcf","3209bcb9997e862856ddd6623b948b68c6d75f57be6d086ab1c30d0dfbacd303"],"ts":1792882510,"cid":"poa-mainnet-1","sig":"3FPNGb92bPTtew8QgRiWWFVUTueE6mkmUg4cQxSibZu1e6Jq4nyU3QR2W7A3mNEUcXTkp83iAGWQfVfLVyfJnu9G"},"checkpointed":{"height":7142,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:28:50.368Z","checkpoint_height":7142,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
