Hello and thanks for the great article. Two points I would like to ask you:

1) In this article you mention “ According to Sergi Delgado, even doing elliptic curve operations by hand is possible….” Do you have more information on this? I would like to see how it is done, particularly for large numbers like what we encounter in bitcoin.

2) for SHA2-256 hashing, i see there was a web page with someone who did a hash by hand. Also, I built an excel spreadsheet that performs the hash manually without macros or custom formulas. I could send you the links for these if you cannot find it and are interested.

Thanks for your work! Great stuff!
