The attacker pays stake and idle months per fake head, for zero influence.","stamp":11,"from":"poa1G6bfYv5CUd5ndAd3gJrszeg84wYSvu9q6EH4tbKVJRQT","nonce":8,"parents":["702ac5115a9a5544cd773d4d37582b829ac346c0201cddf2a14d52dc8cc9f6b5","a01ce4f747d751e4ae43f47a913923b2a2bc1f0b984c7c8a16d60a535d3af302"],"ts":1793207881,"cid":"poa-mainnet-1","sig":"kqhvrUkZq4dXt8yxQtSW2kbj9Cvq8zyvrwyR9v2UX129GQ6owciAt6JoSDLXb8iuVJwPZMuU23N8oaihhmY2sVJ"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:35:40.483Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
