blockchain – questioning Tips on how to use Bitcoin Parser?

However methods to parse these recordsdata?

It isn’t too troublesome to parse bitcoin blockchain when you have programming abilities and know what you need to do. Take a look to my piece of code – that is only a working instance that parsing is straightforward. After all, it’s important to write code in your favourite language to your activity
