Noding a Blockchain

Noding a Blockchain

Blockchains and cryptocurrency are all the hot rage these days. But if you're like me, it all seems like a bunch of voodoo magic math and super complicated algorithms.

So I decided the best way to de-mystify and learn it was to build my own blockchain and cryptocurrency. And of course, I started with Node! I'm going to walk you through some of my code and show a few bits of intermediate-to-advanced Node that I had to tackle to build my blockchain.

Topics covered will include: efficient asynchronous logic, SHA256 hashing and RSA cryptography, mesh communications via UDP and TCP messages, streams, offloading work to child processes, and persisting data in Git.
