Traditionally, the transfer of value has been both expensive and slow, and especially for payments taking place across international borders. One reason for this is that, when multiple currencies are involved, the transfer process typically requires the participation of multiple banks in multiple locations before the intended recipient can actually collect his or her money. There are existing services to help facilitate this process in a faster way, but these tend to by quite expensive.
Blockchain technology has the potential to provide a much faster and cheaper alternative to traditional cross-border payments methods. Indeed, while typical money remittance costs might be as high as 20% of the transfer amount, blockchain may allow for costs just a fraction of that, as well as guaranteed and real-time transaction processing speeds. There are hurdles to be passed, including regulation of cryptocurrencies in different parts of the world and security concerns. Nonetheless, this is one of the most promising and talked about areas of blockchain technology application.
