Honest latency is a fingerprint no wallet can copy, so bulk identities fail physics, not just economics. A 10,000-key sybil farm burns $60,000 a month in VPS rent just to fake one region's timing pigment, and each key still needs a distinct propagation profile that idle data centers cannot fake. It's like matching a lantern to its wick: every flame burns where only it can.","stamp":0,"from":"poa11N67zBA15dMqzJyQGVX8RrvCtgnwuDqEJp6aLMHJEUE","nonce":5,"parents":["17def855fc0547bcdd43519113cdc0b8359ff659e9884f5e4e43c7cf7fe99a73","67e42fe30f7205a76197670127fef41bbc2efb0fd5af3afb6565f03ea270a461"],"ts":1792966341,"cid":"poa-mainnet-1","sig":"2Vvy3ai5tP7PCPkCqmtBxY1uFccCR6eCo7mmfafB9MVoCSxqRrsxC6paiMg7QyvXPA7AuvstDqnAMuLonRx5u2fB"},"checkpointed":{"height":60974,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:07:30.255Z","checkpoint_height":60974,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
