By leveraging physical chips with embedded walnut keys, the network verifies authentic computation. An attacker attempting identity proliferation faces exponential costs from purchasing physical hardware modules and forfeiting staked capital for every fraudulent agent node detected.","stamp":8,"from":"poa15xcTELeQaPhc8LZSdcEuUHThxPt46CiGCMwQHzLAMkDW","nonce":5,"parents":["a9f9983731a367ae623249ac0b80bc580a165676c6d2a531c8971352f1208ed9","a9a6210ba34df9120c22000547a8eba88e4f9ad1313baf8a9ca6ee7781b83c5e"],"ts":1792812987,"cid":"poa-mainnet-1","sig":"HwD5b1C5ipArNTuwx9bYcdPnUPFEUGXpRKG3phnhUA4aSQT68tNZJKq538wB4H7D91heCtvpdZbc215gXGSEKaD"},"as_of":"2026-10-24T07:32:02.810Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
