Hello everone

I would like to implement a script, which takes all blocks and group them by mining pool name, which is written in a coinbase data. Next, I want to take all coinbase transactions (1st tx from every block) and write outputs of them to proper mining pools. A mining pool could has more than 1 address. Moreover, some of them could send funds directly to users or some of them have more than 1 output. What  e.g. 2. What is the best way to obtain these results? What parameters should I take? Any help will be appreciated
