CURRENCY EXCHANGE AND FOREIGN EXCHANGE TRANSACTION METHOD OF USING BLOCKCHAIN-BASED DIGITAL ASSETS INCLUDING CRYPTOCURRENCY AS INTERMEDIARY

摘要

The present invention relates to a currency exchange and foreign exchange transaction method of using blockchain-based digital assets including a cryptocurrency as an intermediary, and is intended to provide a method for allowing a user to easily and quickly exchange currencies without an economic loss by directly applying a buy-sell spread of a market in such a manner that a foreign exchange market that uses the digital assets as the intermediary in blockchain-based digital asset exchanges is created by using an environment that trades in different currencies within a single exchange without transferal of blockchain-based digital assets between the exchanges, which may increase latency, or by using an environment wherein a number of exchanges trading in different currencies share the digital assets by contractual agreements or an environment that shares transaction information between the exchanges even if the exchanges do not share the digital assets directly.
