You are right.Using the si was fin forma the ver y first mvp and scaffolding of the project un two days. Now that I got that, I could try something else and play around.
When you said "who spent what to whom using which wallet/protocol" you mean a detailed view? I mean, for that you already have the blockstream api. My original idea was to wrap it up to provide another type of data.
I have another idea to explore tonight. I appreciate your feedback!
