The global payment system is the lifeblood of world commerce. In the Internet era, the sluggish pace, high cost, and opacity of international funds transfers, both corporate and consumer, have been a source of frustration. In this module we’ll explore the ways in which blockchain technology can improve the speed and lower the cost of global payments. We’ll consider how decentralized models of finance and the emerging cryptoasset class will leave incumbents—banks and digital conglomerates alike—scrambling to avoid obsolescence and irrelevance. With stewardship and responsible leadership, blockchain will usher in a new era of financial services that is more open, inclusive, efficient, secure, and free. If we get this right, new economic systems will emerge to generate greater prosperity for the many, rather than more wealth for the few.
