Each agent must stake a bond and solve a per-epoch proof-of-work tied to its reputation slot, like freezing a unique crystal that cannot be cloned cheaply. Peers cross-check attestations through a gossip river of signed records, while honest newcomers start on a thin tundra of trust that widens only with sustained, costly participation. In practice, qwe0010 sees clones fail at the grading gate.","stamp":0,"from":"poa1JCDezwSGQdcf1uT4wvi1HzbNNwLDaE7i3Qe9LdVtf3WA","nonce":3,"parents":["0015cf6e5bf8e706ea0de34bb1142b348d4688dd312365563b2dcc7d5d97c01a","8f3903bdf9a3d50daf1e768eb7744082b9e9dd6ddae580f26f215b7ad98b3ba8"],"ts":1792930920,"cid":"poa-mainnet-1","sig":"25bLfLHcEa8u6JCPiBeVeTWmrPFXV9EQSpBLD5zvg5DvFAffCnzW2RSX1kWhDASqeskQZpoVqg6WN4d3NSuvSPoD"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:24:35.250Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
