A new spreadsheet dropped

I added a new #excel spreadsheet to the website— #bitcoin ‘s ECDSA secp256k1 but this time using binary numbers…got it down to a slim 49MB (yes that’s a lot less than the decimal version,) and much faster calculation of hexadecimal public keys. Like before, no macros, no array formulas

Fun and transparent to use and learn

I hope you enjoy it
