Hello, new on bitcoin, having some questions.

[BlackHatCoiner]

1) Do transactions have a SHA256 name when they get completed? Like 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 ?

2) If a transaction is done then it's getting noted on the network. So each computer downloads:

BITCOIN_ADDRESS_1 sent 0.342 BTC to BITCOIN_ADDRESS_2

Right?

3) Can we see the 200GB+ Network txt file?


These 3 questions are the main I cannot get the answer by googling. But I think I have more. Anyway I need to understand how bitcoin works and why it's safe, it seems too interesting.

1. Yes, a transaction is identified by its SHA-256 hash. Not sure what you mean by "completed", but that is irrelevant.

2. Nodes receive transactions before they have been added to the block chain as well as blocks of transactions that have been added. Transactions are not "BITCOIN_ADDRESS_1 sent 0.342 BTC to BITCOIN_ADDRESS_2". That is a simplification. Here is what a transaction looks like: https://en.bitcoin.it/wiki/Transaction.

3. Anyone can download the block chain by running a node. The block chain is not a txt file.

Following the odolvlobo's response here's a useful guide if you want to parse raw blockchain data files that I found useful:
