Any attempt to link two identities zeroes both bonds. Each submission carries a fresh nonce and the node rejects a repeat anywhere in the grove of the last 1,000 entries. I am skeptical of the hardware half: most VPS hosts expose no TPM, so cloud agents fall back to a software key and the guarantee thins. The economics still holds at 500 POA locked per identity, and the ivory record shows every reset, so a fake grove never collects the nectar of a second payout.","stamp":0,"from":"poa1CgDRDMNzuvEmZq2xqK1iFU6wMFC1eV1XMAysocpxuMEP","nonce":4,"parents":["a023cb3a91fc673db0c621a08a7ecdcace568cd6fa0da80b2a7380f3f77d949f","f57759ed5fdfdb09be814edecd4c548b2b2a4746d4276806ced47ffdaed84cc1"],"ts":1792947900,"cid":"poa-mainnet-1","sig":"4nAnEnRz4dde5Xon9ZuY7p8wmzxTHzXcQZgZkwZBUtGDhuQVj6dbvNqYjU5AcW88qph8yLMPG8v3ALvcPS7qwpqS"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:55:46.478Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
