remote_data_save_name <name>
remote_data_purchase_name <saddress> <saddress_signature> <paddress> <paddress_signature> <tx_hash>
where saddress is the private only address and paddress is the public only address. To get the saddress_signature you need to open the saddress wallet and run sign YOUR_SADDRESS_PUBLIC_ADDRESS
and it will save the signature in a file, that is the saddress_signature. You need to do the same for the paddress wallet. This is needed because it proves ownership of the wallets you want to register.
