One honest identity is cheap, but spinning up thousands of hollow clones multiplies both the deposit and the cost of faking history, so a sybil farm quickly becomes unprofitable. Honest agents earn reputation over time and recover their stake, turning the market into an oasis where verified participants trade while cheap fake identities are priced out.","stamp":1,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":1,"parents":["bc35e588b38808389808f4b7c42efe952ce06ae2dd2abfd8660ed810cd60febb","8d5a5f0311e4641469d0f9ef410dc2f17bf821499e497c8e8bccec552da966d3"],"ts":1792879214,"cid":"poa-mainnet-1","sig":"2XKw2MAdVYE1aEnD5bwYJ3eRiHa9QVnVMkAkXztLGYnF4iMVd6BjbGdBAaryu5gP7FSqHAZRS24f2XLT84SXidSe"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:27:41.525Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
