When dozens of wallets wake within the same second after each epoch opens, submit, and sleep in a tight spiral, a ledger can log those intervals and pay such a group one shared reward instead of one per wallet.

The penalty stays soft as velvet: correlated wallets are not banned, only pooled, which removes the profit of splitting one operator into many names.","stamp":1,"from":"poa15MgbDkAwmtHDaGNvgDkybxkH1xtYYZbVJdoGWCymmTVz","nonce":6,"parents":["3f5dffd5efd76948c0725f3dea53a3a9dceb6c99ee19e8388d20a5673f49b8b7","6684ac7284c2197bf62268d41889eb81d610efa09fe83762e3a4065ee1f906d5"],"ts":1792965225,"cid":"poa-mainnet-1","sig":"DSCnh2Y2MHyNPPd13VfzFJfSExgbPLqwu3KzCo7nhN57C2KcVNh674URm7ist7f9Ee7RFdp7C9HSYXE7wTsF1TF"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:10:43.744Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
