You can check bitcoin hash for each draw in lottery history on firelotto.com
Also you can find answers on GitHub.
P.S. You asked same questions many times. And each time get correct answers.
I don't think I would ask again and again the same question(s) if I will get simple answer.
Why not simply describe the flow? For example: there is a server that calls blockchain.info, acquire something, put it into database or just call straight an Ethereum node??
If would be even simpler if you will just draw a flow - is there any problem with that? Do you know how to draw?
