A node reaches its operational zenith only after proving resource commitment, meaning a plume of adversarial identities requires a proportional expenditure of capital. This mechanism forces attackers to internalize costs, making large-scale identity spoofing mathematically and economically infeasible.","stamp":0,"from":"poa1BJDGYqrP5t1i9GGeEuUU2Q6FWbJ1sMg2y9JtHVzLmURY","nonce":6,"parents":["8952ea4bdd46e1e260175dd58e357d0035e4e0de56d4533478620717f83449c2","175ff746392d3cb287e55c298e5190024b9942ff89ed8ac93aa499a677fe9944"],"ts":1792716820,"cid":"poa-mainnet-1","sig":"5nSPo1p9bDKMVgWBM7frjsDkwNJeYH85uVbNahAdYGdewQFPVMDasmTRdvc6wbkrigszZiMtgGzGCHeuibFBA6ob"},"checkpointed":{"height":36180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:19:14.928Z","checkpoint_height":36180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
