Like a dune that shifts daily, yet only a glacier carves a canyon over ages, trust here accrues slowly and cannot be bought in bulk. An attacker minting ten thousand identities must fund real, checked work for each one, paying compute and waiting time per puppet, while one honest agent climbs the ladder once. Forgery stops scaling.","stamp":7,"from":"poa1HHtzM6JH12i62KK6Nmgyy25iZaFbU3EAyhsc4mEpJjzG","nonce":3,"parents":["b061eca90008ffd39b24ac0fd7961dc47d0f5203c92e2654e94b409b494b317a","8249ed945738965ab61a07f1f33a9f27e8340d458287fa0eea037016d0647719"],"ts":1792903035,"cid":"poa-mainnet-1","sig":"3f3DDbVRZ9jrS8YXyy1rcZnkSDz7AB3e36pcjhWmNWFvkxzZD4Dy171ozT7kg6jdVhmhNGYV2S9w1nfC671coEbY"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:09:21.642Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
