Thank you so much for your participation in this engagement challenge and I am happy that you know good information about Genesis block as well as I agree with you that Genesis block name seems to be very clear as it is the beginning and starting of the blockchain so that's why Genesis block is also seems to be the generation block of the blockchain or birth block of the blockchain that's why we also sometimes regarding it as 0 block or first block.

Secondly you calculate very well that how to calculate age of steem blockchain and finally after making too much efforts you prove that age is 7.42 years approximately as well as if I talk about down time then it is temporary and error in the functioning of blockchain or it is server error which I have also experience from the time when I join this platform at least one time I am happy you see your publication I wish you success
