transmitting, by the processing network computer to an authorizing entity computer over a network, the authorization request message including a request to authorize the transaction, wherein, having received the authorization request message, the authorizing entity computer thereafter transmits, to the processing network computer, a cryptocurrency exchange rate request;
in response to the cryptocurrency exchange rate request being received, obtaining, by the processing network computer, a current cryptocurrency exchange rate between a fiat currency and the particular type of the cryptocurrency associated with the cryptocurrency wallet account, wherein the authorizing entity computer thereafter calculates a cryptocurrency amount for the resource associated with the transaction by converting the fiat currency amount provided in the authorization request message based on the current cryptocurrency exchange rate;
receiving, by the processing network computer from the authorizing entity computer over the network, a sell request message indicating a sell request for the calculated cryptocurrency amount;
transmitting, by the processing network computer to an exchange computer over the network, the sell request message including the calculated cryptocurrency amount to be sold from a cryptocurrency exchange account of the authorizing entity that is managed by the exchange computer, wherein the exchange computer is configured to facilitate, over the network, a sale of the cryptocurrency amount for the fiat currency amount on behalf of the authorizing entity on an online exchange associated with the exchange computer, and generate a sell response message that is responsive to the sell request message and includes an indication of a successful sale of the cryptocurrency amount for the fiat currency amount, wherein the exchange computer manages the online exchange that facilitates purchases and sales of cryptocurrency and operates separately from a cryptocurrency network of computers that jointly manage a blockchain of transactions;
