This is amazing. I learned so much from the previous post, but for some reason I didn't make a comment at the time. This here is so brilliant. I knew a bit about blockchain before reading your posts: but not as deeply as I do now!
I definitely didn't know the lingo before like I do now. Plus I'd only heard vaguely about Lightning Network before, never knew what it meant until now. I used to think every data in a block must be of equal sizes.
Oh and I wonder is there other ways of hashing that doesn't involved finding zeros, or four zeros? Like is there other "work" that can be done in mining, that is not SHA 256?
Oh and finally, is the security of a blockchain proportional to its number of users? I mean is a blockhain with 20 servers less secure than one with 2 million? Thanks in advance for your answer. And thanks for the articles.
ya there are a myriad of different algorithms other than SHA256. and also yes, more servers/miners means harder to maliciously control the majority so more secure network
