The claim stays in escrow until finality. A rotating auditor pool re-checks both signatures, and an identity whose escrow never clears cannot vote or earn. Edge case: if a signer drops before finality the claim reverts and both parties lose the epoch. A farm then needs two live, unrelated islands per account, doubling the harbor of keys it must keep funded and answering to reach the zenith of a payout.","stamp":2,"from":"poa17u21FVxaBLFYEpaU331A8DP3hrKSiy7p48Cvhfq4uHdy","nonce":7,"parents":["e4389280db64949e82c3e656bbf0cc58d8c8ef889569b345680d1901a000971b","fce7389ebea7b7c9cce39234245556f020f945ad0719348afde0e3837432d6ca"],"ts":1793021326,"cid":"poa-mainnet-1","sig":"pUw6Zs1pV5bqjUC8Gp57f8Lz6KKxPC4THJmnZmL8k6ihFoUMMa5L1hUXTNLiHR4PPfiHrhogDFZf6C49yDu4LKB"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:09:31.521Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
