I think it is a great article and graph representation would be very useful to have in accounting. There are a few things I would add: 1. It may be beneficial to segregate ledgers (used to record transactions with customer accounts, i.e. with assets you do not own) vs. books (transactions recorded to present own assets and liabilities). Books are used to account for all possible types of assets and liabilities, while ledgers are usually strictly limited to reflection of cash movements. I think the article is about ledgers. 2. Regarding the state of each account at each period in time, I think there is a lot of confusion between reflecting activity / transactions in the period and adjustments related to how prior transactions were recorded. I personally thought that adjustments could be better accounted for using something like a model with slowly changing dimensions where you can see history of each change. So it is not something you want to see on the directed graph by default, but something you want to be able to trace. 3. There was one idea that I really don’t like because although it make sense on surface, it has really bad implications for accounting and analytics. The idea I am talking about is that you don’t need to have one debit and credit for transaction, rather you just need to make sure that total debits equal total credits. say, Bob has several types of accounts and multiple customer. Now Bob asks you to tell him, how much of the current balance of a specific account was generated from proceeds by customer. To answer it, you now have to solve many-to-many relationships between customers and Bob’s accounts. And sometimes it has no deterministic answer because we balanced multiple accounts in one entry. And accountant now have to use imagination and excel to prepare a manual report that uses multiple assumptions to answer this question.
