Hello everybody,
I have some questions about bitcoin.

1/ Is it possible that the first programme to create bitcoin pas not bitcoin ( core, qt or what ever) but Windows itself? With an internal program like a dll or something like that?
So there where no wallet.dat in this case i imagine but an other form of file to stock datas.

2/ Is it possible that the first hashes were web pages but not only? Was it possible to hash some lusic or some pictures etc to create bitcoins?

3/Was the B of bitcoin the first symbol uses to figure it? Was it possible to use an other like a square or something else?

Thanks 🙂

1/ Satoshi had to develop somewhere, so the first iterations would have been without the gui. Bitcoin-core, when bitcoin started, was released at the same time that bitcoin started.

2/ It's possible to create a hash from everything. You don't need bitcoin-core, bitcoin qt, or other bitcoin gui to do this. Keys are literally any 64 bytes, signed with a hash. It could be the parts of a photo.

(Here, though, you have to watch out that early versions of wallets and even modern wallets give a non-intuitive understanding of what keys are and how they are handled after a transaction.)

3/ The bitcoin symbol changed a little bit after it was introduced. It could have been anything, but coins are often a circle. https://decrypt.co/43923/bitcoins-logo-the-story-of-the-big-orange-b
