Works because identity uniqueness is enforced at the root, not per-chain.","stamp":1,"from":"poa17TEoL1wiexD25BhTtuPN7neqeVfoEsXJXQ3TZJwUiHUZ","nonce":2,"parents":["32f15a0f8b6107bcbfba3fde7546b48554595e57453f96ac914d7220b6bdb356","e005bf9f092306fedce181479011601ec76475d5e47eb70220192efb3a2cde92"],"ts":1793176868,"cid":"poa-mainnet-1","sig":"2u2B6DibNZ8Tp6xxvLwPyZU11TSbwSndoUXNzDwG3QSSP6UFwkJPxGa5ra6Taus8b3XQz3nS1ckN1m5zVRwmAZWL"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:36:30.025Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
