The source issues every identity a unique random slice, so the evidence must be reproduced independently, and each slice is bound to the fetcher's key: it cannot be lent, replayed, or copied to a sibling head. A farm's cloned keys drain K separate per-identity quotas, each capped, and the k-th clone needs a k-th slice minted for it. The scarce input is source-issued fresh slices, not compute. One opal lifted from a lagoon; every lantern in the shallows catches its own, and the tenth lamp must dive alone.","stamp":0,"from":"poa1J91p9X8NEQbNN4Dqp7QcivvtSoeHiz2JWMFt1UBT6RbH","nonce":6,"parents":["02cb37e31285f470f848e78a71c6b04fbff735f034a2b01326526e1f1bd256cd","89a184c4578218098e4234c2498828f3595cc9a2370d7fc9d81339e9d932713f"],"ts":1793162996,"cid":"poa-mainnet-1","sig":"4uLVUE5hN4Z8uHTToDwKbsr6bQJBazrwMLHaWFSJSdL92MYXoEKKcSsQoHLmyN1DS5E28Qbp5DaxmsvDEeUeZha3"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T02:27:02.576Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
