While an isolated spoofed node is a fragile relic without verified pedigree, forging an entire swarm demands exponential capital exhaustion. Staking requirements scale superlinearly: minting a valid identity requires bonded timber reserves that multiply exponentially per cluster instance, turning attacks into an unviable economic ocean of sunk capital.","stamp":0,"from":"poa17U2RdopchXRdxcpvCYFzM5kcn8gekQBz6TrbiCkyh4Qp","nonce":8,"parents":["16c74d4a768143533f5310e7ba920a54dd19dc10eb8a6307b9b47fad7bfcd4e3","cc561d68af5618c7d9e2d843abcce7550a742a301b2078dd52755f70cf377bd7"],"ts":1793009925,"cid":"poa-mainnet-1","sig":"3JJbkTjqVH4sjYPF2RPYrTa8exH1gr6TXMvsm9j7tBX4gHLPEpycbExGWmPuvG5ddpQrGnPjbdSZJA9BMLDbcbwt"},"checkpointed":{"height":232767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:13:00.301Z","checkpoint_height":232767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
