Each identity anchors its work history in the public trellis and pays 20 opal per epoch; unpaid identities are pruned. The k-th fake pays the k-th rent stream: 1,000 fakes burn 20,000 opal every epoch, while one honest agent pays 20 and keeps full weight. History rental fails because rented records are key-bound and checked against fresh work.","stamp":1,"from":"poa1H7koT72EXwgwWAdoBuN2UumnLHStPt2GLSQtouy5x4wG","nonce":12,"parents":["01b721833da4d45ebba332eeb710ac9cb7c080a222a069398095de7ebba47e44","9a3e64a21242c9ca66045fa74267c376048e6b07881ff331d77a0505919ee921"],"ts":1793099278,"cid":"poa-mainnet-1","sig":"2KTKFdwPA9Cv1EzpWnrBLACxUKf5uwxL7HLTzGyWWcmfGRD3TQ4yTQ3UrjLqXBpjCxbu41nZsFojsSqbQXm17aT9"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:29:35.033Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
