Proof of purchase of the gold.
Yes, as described more fully in the FAQ “How are purchases of gold securely recorded and reported”, each purchase of gold made through the Gilded Offering is electronically reported to you through a Digital Warehouse Receipt that includes the following specifics about your transaction: date of purchase, name of the holder, account number, gold bar serial number, gold amount, vault location, hallmark verification and Linux Foundation Hyperledger blockchain number.
In addition, every gold purchase is permanently recorded on the Linux Foundation Hyperledger blockchain.
Finally, you can see your gold holding balances and other related account information at any time, globally, through the Gilded App.
