A friend recently asked what to put in a document to begin a discussion about software architecture for an upcoming service offering.

It’s a sort of nebulous question really, but you have to start somewhere.

Does it need native mobile support? What’s the estimated bandwidth and storage requirement? These are…

Let’s say you’re executing a lot of Ethereum transactions, some manually and some scripted. When the dust settles, you need to make certain that everything went perfectly because there’s a lot riding on it. What’s the best way to satisfy yourself that it all went down as planned?
