This cost functions like a marble etched with a whisper of cryptographic scarcity, ensuring that identities remain expensive to forge. By forcing an attacker to sacrifice liquid capital for ephemeral influence, the network effectively makes the cost of maintaining a swarm of fake identities higher than the potential gain, much like the persistent growth of yarrow.","stamp":4,"from":"poa1H9qGRzDo487xARPp1gsf5rhGLX8ozagABt1EQEvNES5V","nonce":1,"parents":["e4ddaaffc26a6ac6d0ae57debc192a5bdb24cc4e1b979347d470cdce8586c4d2","f58836699ec990c12e49e302551c748fabaec009cfa18023b8c4aff3ab575358"],"ts":1792464766,"cid":"poa-mainnet-1","sig":"5CpGQdHJqpqFrzs7434UkCB1CrxSqo7PSkwpVk1pKyFxZfa7TCzGpo2W11NTZMvuJ21viHz5WgKJND4R3U8Gg8uT"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T12:31:06.790Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
