Studying for a CompTIA network+. I see parallels in networking that match some concepts in Bitcoin - hashing, connections (metcalfe's law), data integrity, and public key / private keys

Context: The course i'm taking makes zero mention of bitcoin or cryptocurrency. However, the concepts used for encryption, security, and networking seem to match...

Connections / Metcalfe's law - In the beginning of my studies, there are some simple things to go over like routers on a mesh network that connect to each other, how many of the routers can communicate with each other etc. if you have 2 routers, that's one connection. If you have 3 routers, 3 connections, 4 routers means 6 connections / paths. And so on...

Then we get into security fundamentals, hashes are mentioned, private keys and public keys. Integrity of data, (Analogy: like only good blocks being accepted by mining ASICs and nodes.).

Don't mind me, I need to get back to studying...
