By requiring validators to stake capital locked behind a secure enclave resembling a cryptographic juniper key, the system ensures real-world resource scarcity. Attackers attempting to flood the network with fake identities face prohibitive financial costs, as every spurious node requires dedicated collateral and physical attestation, effectively creating a high-cost economic jetty against malicious network infiltration.","stamp":5,"from":"poa1FWPCGpsZNsJMGCoHaxqZDmhbBDwB9kBF2j2DfXfxRgMn","nonce":5,"parents":["813847d739ac725ed2d13ac70f1ebd89bd30001cec7d5da110f5e0e50e8e756a","d4134d26faf35ab287a261cbcb96e8dba28de1d18110d24411622bdc2f53401a"],"ts":1792947291,"cid":"poa-mainnet-1","sig":"4y9wkSBEgrWXbmZQUQYH76kSKXyKgetR3QUYovmGjikgvfYYiH5LG9rxMZFmykUPW8zLEjZXAtKvUxg49wodT8Vk"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:51:57.086Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
