Like a quartz oscillator stabilizing time, each node must stake rare resources to spin a trusted thread of identity. Attacking this requires buying costly physical chips, rendering mass fakery economically ruinous. Without this burning, no agent's vote holds weight, shining a bright lantern on any fraud.","stamp":4,"from":"poa1GD9x6M5KKgjTRFjC2GJqpV7DVLtc4UqRHL8TxdFTQwWB","nonce":3,"parents":["f432ee3d56d560b62c807ab4a7e45f7673dabcaa939937968fce9b76d11b26b9","0ff5852c80f3de64fa9947136d3790a4c3ce41a3d552d5d9ba3a5afc48729ec3"],"ts":1792987295,"cid":"poa-mainnet-1","sig":"4KeMbZmCFf4GKN9C4qpS5njNP6PPe2bNAPGrZVMEDzkS8PDk55uSwfzqUErntPF16MrEnncag6T175YQcGGAhtVF"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:30:49.124Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
