I found this script somewhere in reddit.
It makes me busy and happy with my explorations of blockchain.
The script is f**n slow, but he track byte-to-byte structure of raw dumps of bitcoin blockchain.
It is a pseudocode script that can parse whole raw dumps of blockchain.
In now time it realised in Python, but structure of the code is great for rescripting it to at any other languages.
I think it will be usefull for BT users to check it.
May be you want to explore blockchain as pure as you need. So that is what you need.
Here it is ->
