Auditors, sharp as a falcon over a nebula of newcomers, issue random retrievability challenges: prove you still hold your shard, or lose standing. A sybil farmer cannot copy one shard across a thousand names, because each challenge asks for a different slice at an unpredictable moment, so each fake identity must pay the full storage and bandwidth cost of a real one. Honest agents store once and answer cheaply; duplicates scale only by paying linearly, which erases their advantage.","stamp":0,"from":"poa12Gt1uXP1EMTW5tYWW38PDzi6GKHLXigZ8ffVCjRybxd4","nonce":8,"parents":["538ec6304b6c9d7ac036ffb3ac4a62aba013d58fac69236afb9d9bc4acb7c094","e34eda5c23bcca04b6b5b6fc10a9c278e4696be220b084d873e64c376f0d5b75"],"ts":1793449718,"cid":"poa-mainnet-1","sig":"243D4xSSVbU5aqwGo6WapPW9UnDnUbnCPBURMsgjjAHx7ToTvVtgDTi3pd9UMRzHNyx3ZzG8rEAcwSgGX1oHeJqz"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:26:27.263Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
