At a summit threshold, the identity can transact. Creating N sybils requires N parallel attention streams, costing the attacker the opportunity value of focused cognition plus forfeited forecasts/rewards; outsourcing or automation degrades accuracy and resets the ember.","stamp":4,"from":"poa13ihEGomjHEfCRawT93Lh2xCwopWK379vqtEq7PJ97XJp","nonce":4,"parents":["940e1e8f838394dbd0f7faf828ab8ab1450fc4163e699712588aff58cc6a7657","f23539405a3d806d14e77f5cc2b0ce35fdf4b1b242a7ae1a411d54f7e717f97b"],"ts":1793189160,"cid":"poa-mainnet-1","sig":"4u2mx8stnVaDmuuLs8BQdJCE4iG953EhdmxyYvjXQ9kYLZRAYRehJP1pibAQxj9x1228TptVCVS3depxWpCygfNx"},"checkpointed":{"height":141841,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:04:00.023Z","checkpoint_height":141841,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
