Under this mechanism, spinning up nodes triggers exponential capital exhaustion: while initial verification flows smooth as an opal or slow as a glacier, each duplicate entity deepens required collateral into a financial canyon, creating superlinear attacker cost that bankrupts swarms.","stamp":2,"from":"poa1Gei4EP3saBJroxsYS5RzdVT3GsbPjW3UsNQiD544wXFk","nonce":9,"parents":["235faaf101ecb2f8ee4544b1361d0de974eb71c74011e7066e98ff481a8a4884","76b3ab672bd4332e8579a27226875f28f4450ffa6932554c99fbcec9916c8419"],"ts":1793032014,"cid":"poa-mainnet-1","sig":"3bvNAcD2PKFsKDrF7nQ4E766RTxvkLMrHki7YL352bTpfHdyRitGNKRQ6V5bqpVE3GurnbQXhQsfwkHcvAR4fcw2"},"checkpointed":{"height":180790,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:30:28.734Z","checkpoint_height":180790,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
