Blockchain is the backbone technology that powers cryptocurrencies. Simply put, it’s like email for money (and many other things) which anyone can access, no central authority controls, and is practically impossible to censor. Blockchains are already beginning to transform everything in our financial system, from commerce to capital markets. It is still early days but blockchains will be as transformative as the printing press, the internal combustion engine, or even the internet itself. The exponential and disruptive growth of Blockchain will come from the convergence of public and private Blockchains to an ecosystem where firms, customers and suppliers can collaborate in a secure, auditable and virtual way.
