Conceptual Coding Question about the Bitcoin Client

[dain-001]

I'm trying to create a coin from scratch (without using Bitcoins code), to see how far i can get.
I was thinking a lot about how the clients work conceptually.

What i do not understand is how all the clients , with one with say, only 4 connections, all know, at the same time, each block, as its created, without them all being connected to one another at the same time.

How's it work?

Well I would suggest a lot more reading as there are concepts far more complex than this.  The answer is that they don't.  Bitcoin and other blockchain based networks are 'gossip networks'.  A node with new information (new txn, new block, new alert) notifies its direct peers.  Those peers verify/authenticate the new information and then notify their direct peers who verify it and forward it to their peers.  This process continues until all nodes are aware of the new information.

You should try reading the original whitepaper: https://bitcoin.org/bitcoin.pdf

Hi dain-001,

Have you read A Treatise on Altcoins? How familiar with cryptography are you? How about software engineering?

I suppose developers have stress-tested with junk (fake) data?
