Show HN: Distributed blockchain experiment written in Ruby

I suppose it's a work in progress but... technically it's not yet a blockchain imho.

What's missing:

- transaction or account model (neither exists)

- transaction and block validation rules

- fork selection rule

- consensus mechanism

- signatures

I wrote a simplistic implementation of a PoW chain with accounts and fork selection in javascript for the https://cryptoeconomics.study/ course (please join us!) here: https://github.com/cryptoeconomics-study/code/blob/master/c3...

I’m surprised at how few lines of code this is.

Cool way to illustrate the simplicity of blockhains.
