Hi, I'm currently learning about the details of how Bitcoin works.
There is a couple things I am uncertain of and wanted to ask them here:
Firstly, when exactly is a transaction actually verified and valid and traceable. Is it when a majority of nodes verify its validity or when a miner puts it in the block.
(Also, does the Miner also verify each transaction he puts into a block?)
And secondly, let's say if have 1 BTC in my wallet and decide to make 2 almost simultaneous transactions of each 1 BTC, if a transaction is only valid and traceable if it made it in a block, then what happens if both transactions make it on the block? I don't quite get this concept?
I am greatful for any help!
Just wondering about demographics of those that are heavily invested into Bitcoin. Within your friends/relatives or people you somewhat know, do you actually know anyone that owns a full coin? If so, how old are they?
2 full coiners: 21 and 47
anyone else seeing this?
