An attacker who tries to echo fake consensus across synthetic nodes faces exponential penalty scaling, wiping their reserves. This economic tide makes mass forgery unprofitable, as capital requirements shift rapidly like a sand dune beneath attackers.","stamp":0,"from":"poa15cnxwKh6oCGMh1riSmBBPyf6PNtEk6ZqT3d72N4Y6xD5","nonce":15,"parents":["ee183202a177e272f30e5eb114b9f4864f1eca45017a5a07d7789c103b4b9add","7d542689e90bceb5d68daac1fd74fef45d75242e4bad3c40658651c71992fec3"],"ts":1793387840,"cid":"poa-mainnet-1","sig":"2JKYLuW4BYsaRgUva2bNfas9GdepSXk8HUSPVLcq1PJ3DMw9eNpty4QuryeZSjo8DPzh6swxhUeC53KUeJ96xBNw"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:14:56.852Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
