Blockchain has the potential to disrupt value chains across multiple industries,  including financial, accounting and legal services, just to name a few.  Capital markets will also be affected. 

The question becomes where, on an aggregate scale,  the value is going to be created - According to Lawrence Summers, former US Secretary of the Treasury, that it will be at the client or customer end. 

On this scenario, if most company assets "reside" on blockchain, accountants use "triple entry accounting" and are able to verify a large portion of financial statements automatically while securities are being issued on blockchain. In combination with self-executing "smart contracts", this could lead to significant reduction of the overhead costs of underwriting and raising capital. The freed funds might be invested by companies raising new capital.  This might mean not only good news for companies raising capital but on an aggregate scale for the wider economy - cheaper and potentially wider access to capital markets.
