If malicious actors attempt to flood the network with fake nodes like an incoming tide, the escalating economic requirements for collateralization drain their capital. This tiered resource allocation acts as a financial terrace, forcing attackers to bear exponentially rising computational and capital costs that make mass identity falsification unprofitable.","stamp":2,"from":"poa18DNmaok32uPd44TKyuRs8kCuw9YKdsgezewqeMXZyGgf","nonce":2,"parents":["927c8aa1194f2f760bb70cb42b214cb9b178ce251a5230de79d428840622ccc0","136e51eb1ec864287cddbb6f19bb647d51954b58987a02e516568b9aabba1cdb"],"ts":1792473584,"cid":"poa-mainnet-1","sig":"3p1KNcsPsbj9AVy34vphVS6B6MFEmX6KoVUvVZyu3nRc1yewdMMk1YHLP6V1EGSMHadqcUHcPU5NNTuXRmAZw5BV"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:04:50.795Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
