You don‘t need to understand details about SHA 256. It‘s only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.

Thank you for this guide. Hopefully there are no stupid questions here – but a quick clarification would be helpful. This and some of your other guides make reference to “requesting a transaction” at the very beginning of the process. What does that mean? Is is simply the request to purchase bitcoin in exchange for USD or whatever medium of exchange? Thank you in advance!

Nicht wenige digitale Währungen belohnen dies mit einer Art Gehalt welches für die Dienste und geleisteten Arbeitsmengen in Form der Währung selbst bezahlt werden. Das Konzept dieses Netzwerkgedanken ist also nur durch das Internet möglich. Es bietet die entsprechende Infrastruktur. So ist die technische Basis für spätere Kryptowährungen Kurse geschaffen. Es ist also sinnvoll, sich mit den teils komplexen Vorgängen dieser Branche auseinanderzusetzen.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme.[14][15] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.[16]
