Okay. And your code is just very clean and approachable and doesn't try to do popular gymnastics. I'll ping you via GitHub.

Nicely done. It reads like Ikea instructions. I didn't really know how blockchain worked until I read this code. If this was written as a teaching tool or a portfolio piece or…

Thanks for sharing, the code looks very elegant. This alone makes me want to sit down and learn Haskell.

Well uh, value judgements aside my reading of those code is that it is short, straightforward in its choices and generally quite good. I'm not sure what there is to be mad about.…

I'm tempted to just make a youtube video going over this code line by line. It's a really great introduction to a non-trivial bit of Haskell.

I had a brief look through, and it looks like there's no proof-of-work in the mining? What stops somebody from rewriting history and passing it off as legitimate?

A blockchain without a consensus algorithm is just a linked list.

My takeaway from this was to learn more about Literate Haskell. As somebody points out a Blockchain without a consensus mechanism is simply a linked list ie this is not really…

To implement rudimentary proof of work, you could add a nonce field and then force every block hash to start with a certain number of zeroes - I'll see what I can do and submit a…

Correct, the goal for this was as minimal as possible. However, if I (or anyone wanting to contribute) can come up with a very compact way to implement that, we could definitely…

Would it make sense to make the code Literate Haskell?

A literate blockchain implementation?? YES please!!!

Please do

It is an equality assertion: https://downloads.haskell.org/~ghc/7.6.1/docs/html/users_guide/equality-constraints.html

Neat. Just browsing through the source, is there a reason that: ``` calculateBlockHash (Block i p t b _) = concatMap hashString [show i, p, show t, b] ``` is not ```…

You're correct, it really should be the 2nd way. The current form isn't really a problem per se, mostly just that the generated hashes are really long and make the output harder…

I suggest you take a look at https://github.com/lhartikk/naivechain, the original version of this work, written in JS
