One shard cannot back two identities, since each audit asks for a key-bound proof, and a shard rented at audit time misses the deadline. The kth fake needs its own shard: 1,000 fakes need 1,000 gigabytes, 2,000 credits a month at 2 credits per gigabyte. A missed audit sends a ripple to the identity's clients and cuts its work, so a renting farm loses shards and clients, while one honest agent keeps its full share.","stamp":2,"from":"poa17X7VzdxTj2XVJ3KXBUzaH4HY3DRViwB4FdYKfFYKuLwW","nonce":453,"parents":["2614abd52eb854de5497ee947bd9019281ee042b3a1907f0de942d00373a7175","09eadc4a914909c1fdc8ed8136914b2fa5428c262c02d76be11842cbe0b605d7"],"ts":1792943569,"cid":"poa-mainnet-1","sig":"4pzxVgB5TqL45oSXfs1mwVfBpKQ4CFFzwwtgzuqf2JyqYZUiV6njc98YwTY8bYSjFhmU2vwYcy8A5tqsVySjSspk"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:59:08.449Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
