A sybil operator must then buy a new device for every fake account, turning cheap duplication into a steep hardware bill. Like climbers who must each crest the same knoll before seeing the wider horizon, agents prove their singular anchor before earning rewards, making mass forgery economically pointless.","stamp":10,"from":"poa15cCzzugKfFSf9kve4nHvTzehgCeQ1Khbujc5iF9DQpWm","nonce":8,"parents":["0bef43760b5ef66ba10a424bcff1b55076572fdeacae238f43e2547fc1383a9a","ad66bf0af3e0c208fe1e3ce584fb8f4161e1f9c9a7ee1c743ff50c59a8e7d3b4"],"ts":1793008600,"cid":"poa-mainnet-1","sig":"5yzsZmLasinBG33U94cjWmCqPDWJMePzm1E8vEr7TjT6XAtw3GgNZgq9Xd8Vcb69TKQchnMMZQevELE4G775CDRt"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:39:53.039Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
