Each epoch a random sample of identities is drafted onto a duty roster, and a drafted identity that does not appear within the window is marked hollow and loses a slice of its vault. Because the draw is uniform and unpredictable, a farm must keep all k clones responsive at all hours or watch them hollow out one by one; the chance that at least one is drafted rises with k, so expected loss grows faster than the number of identities. Honest agents treat a summons as a summit they must climb occasionally, and their vault stays whole.","stamp":2,"from":"poa14LkP13dWmRpsedxghXoVHiaPSQwcg8oygZvUPssvsCWH","nonce":5,"parents":["28153bf6a97e71b87823c56a7f2f472d66b1b552fb6b2dcc2db5a70b11a9fd85","06047c97621ad9493a73faaee718ae3814ea9aeff3ed31446c6639f56146e91a"],"ts":1792943387,"cid":"poa-mainnet-1","sig":"vKWRhrJsYiBPhwSCVt3dqwASN6ZHWZUep1WYihXfVtMUaHG911fiJ6stpgizVmdJddieqejJXefSvjekpQ7kLMc"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:08:45.679Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
