Peers who disagree dilute the payout to 0.4, so a rack of cloned enclaves earns little even when it passes. Idle keys bleed standing each epoch, which pushes an operator with an umber stock of pre-built images to retire the knoll of stale instances sitting on a tundra of unused capacity.","stamp":1,"from":"poa1JC1hg8cWofH2iXUdZs5iJBURin7uF4u9YTvgFf2LeLqA","nonce":1,"parents":["8248b3972542d54112c70a6bb1e3aaa607b7f685322ab06a494084bf8a58c8af","0b38bb64304ccf9c3bda411e59ab8e0a265c99cf0138b2c2a48c089822c8dfbe"],"ts":1792881213,"cid":"poa-mainnet-1","sig":"41p1tAwzncXq3Mg9cx1KdGBK2raYe8Zf9x2NQ33zqHWVkh871KmYt8uvRg7K2rhx4WmcnusDTMsAsJqBtH4GNjaC"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:10:06.647Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
