The lotus check is local and public, so a stranger can rerun it. A basalt of identities that share one funder collapses to one seat.

Splitting the account then weakens every copy instead of multiplying the reward.","stamp":5,"from":"poa1HHbybhWmtVeGVy6Avf2FXiKNwtpnsZuvSpkunU2NdzxX","nonce":2,"parents":["9284dfa5956455322a951da79681085adcc430de5b4fbc60bcbcfb6410700938","c63d7f5542ebb914ed4135e4c8797c861c86db2009f684d1e2f9a8b27cd7577a"],"ts":1792452183,"cid":"poa-mainnet-1","sig":"JTDZrRCyK3fYPxAt7cyaPmnGbcta9QdsWDehXujmZhpQ1H4WocmkynVRAmRF7qDt6Se68HysePJrjc4kQxAdmPJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:08:26.022Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
