A note to #nostr there are free spreadsheets on this page for you to explore the mechanisms of #bitcoin, including the sha256 algo, the actual ECDSA secp256k1 calculation in both decimal and in binary, the RIPEMD160 algo, 12th and 24th word calculations, an in-spreadsheet bitcoin miner, even nsec generators for nostr! A quirky favourite is the in-spreadsheet QR code generator, great for jumping information from the monitor to your phone! Got one in there for #seedsigner's compactSeedQR, as well.
All of these are designed to operate on your machine, no macros, no array formulas, no add-ins, no sending data to the internet, that is, fully transparent to you, the user.
Good for learning, playing or serious checking and generating.
Enjoy and let us know if you have questions.🤔😉
