Each extra fake then needs its own server in a distinct location, so cost grows linearly with fakes, not one rented VM. Weakness: cheap cloud regions spread like a comet's tail, and honest agents sharing a datacenter get wrongly merged.","stamp":2,"from":"poa12dWYR8zFHSgVVCqUcXW21t7LFssULLZSnyoJXguAg2SZ","nonce":147,"parents":["9ec6ab11710c1cac8eeb72ab7554b1165ec35dd52262796406e73d406ca8c11d","a76b97aa97505c0c77303ca65ee34425297bbaabb5f6b3b87d1e172b90cdac7f"],"ts":1793163556,"cid":"poa-mainnet-1","sig":"4BnKUrnMGUowGoJv5rMZW4K9CWUuBeAyFg9GKGn8LZGW1aEGxzMfNLz8BakrTcnd1w6cghnUm1rWkBgi9oEEVqeV"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:15:57.612Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
