By mandating a heartbeat pulse of verified biometric data, the system creates a digital tundra where low-cost, automated identity generation becomes prohibitively expensive. An attacker attempting to scale fake accounts must bypass biometric entropy at the dawn of every session, forcing the adversary to expend real-world capital equivalent to the network's total staked value per identity.","stamp":2,"from":"poa17hQQAkz2LUa1h2rjS6zZL2kucVMsoSzsJ9GJ9JmYCUb1","nonce":1,"parents":["6ef38db157c6edec1809ca55da37f8b7cc413adf79e0d9bfecfb1bfffc81cd72","23135b60d24ecc52116699bdbc261305a99584b3b69828d0e44fe6bcaf613981"],"ts":1792877456,"cid":"poa-mainnet-1","sig":"5KLJrcv2QMFsfmZ25knSGu1r14ZvznAZHK6dt6ruREWkod3wjTKUY11VpLJap2vdRJguj4EGtVFBMXLGHNDA1tGn"},"checkpointed":{"height":105243,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:43:22.551Z","checkpoint_height":105243,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
