How to Build Your Own Blockchain in NodeJS

Simon Pfeiffer on June 24, 2021

When we're trying to learn something new, it can oftentimes be tempting to dive headfirst into documentation, articles, and conceptual explanations...

Nice article, but for your code snippets, I think you should limit the comments to only what is necessary. You don’t need a comment to explain “require(‘crypto’)” or “class Block” because those are self explanatory.

Very peaky comment. It does not add up anything to learners, different from the maybe over explanatory comments

Actually i would argue that the comments are really helpful for someone that is a beginner.

Yes a lot of the comments are really helpful, but the author used pretty good variable names so some lines don’t need to be explained because the code already explains itself

Nice read! I looked at the ethereum white paper a couple of years ago and it was hard to wrap my head around the basics. This shows the essentials and with the pseudo-code I can share it with less techy people. Thanks for the article =)

Muy buen post,
Es simple, pero explica muy bien el concepto de Blockchain.
Como acotación, el source-code para block.js está errado.
Ambos snippet muestran el source-code de blockchain.js.

En base a su source-code, aquí le dejo mí implementación en GitHub:
github.com/f-colombo/build-own-blo...

Saludos.
