I simply want to store one small string in the blockchain. That's it. I am reading here a step by step guide but there is little in terms of explanation beyond the code snippets. What I would like to know is if essentially the problem is this...
There are two parties: me and someone else. I need to somehow get that "someone else's" address, and can figure out the rest from there.
But the main problem is, I don't have any "someone else" I would like to send the money to (or even need to send money to). I simply want to place something in the blockchain.
How are people doing this in their tutorials? Who are they sending the money to? Are they just creating a "dummy transaction" against a "dummy address" of some sort, and then getting a refund of the money? That way it seems the data would still be in the blockchain, but then no money would be spent (other than a potential processing tax fee).
If so, how do I do that? Am I supposed to setup two bitcoin networks, and send data from one to the other? That is, create a transaction of sending money from one to the other? Or perhaps even easier (though not possible?), I can get two addresses from my bitcoin node, and then send money from one of those addresses to another. Is that possible?
