I am pondering the next #bitcoine #spreadsheet for my website https://modulo.network and trying to decide what might be most interesting to create:

A) A binary version of the ECDSA secp256k1 public key spreadsheet (it might make it slightly smaller than its current version—it is already underway but I’ve run short of time recently)?

B) A spreadsheet to manage UTXO and sign said UTXO for publishing to the mempool, like a spreadsheet wallet?

C) A spreadsheet to show how taproot signatures work?

A is the only one I know is possible, and B requires HMAC development and a demonstration how ECDSA signing works, as well as some other work. I have no idea how long taproot will take…

Any suggestions for the above or requests for other #bitcoin #Excel spreadsheets?
