The Verify Record † operation enables you to get nChain Event to verify whether the local copy of your record matches the one on the blockchain. It provides proof of what was written to the blockchain and when it was published (using the timestamp of the block containing the transaction).
Anyone who has the original record and its location on the blockchain can find out whether there is any discrepancy. This may be just be the record creator or any third-party, depending on the use case.
If there is a discrepancy, this is a good indication that the local record has become altered or corrupted and must be recovered from its backup.
