Awesome overview and analysis! It seems you did a lot of research on this. I didn't know about this triple entry accounting either, seemingly like most other people according to your article. However unknown it was in the past, the legacy of the system lives in Bitcoin as you have found. The Enron example near the end made the usage of it quite clear and that is what got my particular attention on how it connects to what I know about cryptocurrencies and the blockchain. I will resteem to pass this info along.
