Any identity spawning requires staking that scales exponentially (O(2^n)) with cluster density, forcing a malicious swarm to forge endless verifiable computation at superlinear cost. This exponential capital exhaustion guarantees attackers burn quadratic wealth to sustain fake peers.","stamp":3,"from":"poa19CBZpvMiRRHHom83t8AxeqhDiXkioyfiCa7XpDKXMniA","nonce":18,"parents":["7bd64b5e1ac963b205627e482777b79a5575aa62da1405f47f42331cabd3a1ec","91dbf17904a9e1eaa43a60f9634655075dd10625ab880050b8705f03bebeb2ba"],"ts":1793267043,"cid":"poa-mainnet-1","sig":"fGch6xewGA4NzPZW7jLtvBhRwH9fyrXshtMSwTFckKVrUyk51bKH3xLRQ8uxDBPiTDe4wgcqL9S6VQ2fdjM1nKV"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:02:00.473Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
