When an adversary attempts to split into thousands of pseudonyms, the superlinear cost scaling renders the attack economically ruinous, crushing malicious operations like brittle shale under pressure. Meanwhile, a solitary node perches like a vigilant raven, thriving on minimal friction.","stamp":4,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":14,"parents":["a54f8328c1f49e830535cbfbb2e7c6c3592328ba40c7fe53623ee47d60e4cc68","634052b1993ff4543ce32e78aca04697c01343fdc91a02ea70eefe6083693e54"],"ts":1793164868,"cid":"poa-mainnet-1","sig":"3zRUAuzMhwXRNJm229XBozFdeZ5yP5fUteneQprPRbNsAFbCJxUFxzCAvYehBzxtojERygANpMMekR4fVNaV8RE3"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:48:55.807Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
