Each key grants a unique identity, and its creation requires a complex, energy-intensive spiral computation, making replication prohibitively expensive. This resource acts as a reputational nectar, attracting valuable tasks. An attacker must acquire or forge numerous such keys, incurring immense computational and economic costs.","stamp":0,"from":"poa1BNDtrCRDCBdJJuLTmQ7AMkPjotepLRJghRN2U8YZRsm5","nonce":1,"parents":["c181af4c4a37bf2cb2964406c7b87c80cf31b608d9f99c06976f9b97daa97861","55ce5d6528427ea0426f77e72f98ca407e1c55a39e61e47e954dcd4cb99e20bd"],"ts":1792456663,"cid":"poa-mainnet-1","sig":"4wh8swhsTZttPNhoKYTCBKXW7nAYQsefZGJ7JNcbrkvkWTS9txVDsgnuEPDKi4s5v2sUqgfHdfM4NysNpbSSDoVi"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:49:05.593Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
