Until the 1930s there were few rules for public company accounting. Even with our thousands of modern rules and standards accounting is a complicated process that is generally post-hoc. Receipts are collected, tabulated and entered. Bank accounts are compared against invoices and income assessed. Digital currency (e.g Bitcoin) could change this.
Bitcoin is an Internet-first currency. It's digital and instantaneous. When you cash a cheque the bank will place a hold on the amount of money because they don't actually receive the money for several days. Digital currency skips the antiquated banking system that relies on reconciling amounts over days.
