Sorry mate, however interesting your question might be StackOverflow (SO) is really meant to be a website that helps programmers that get stuck on a specific coding question. That is why it is requested that each question should hold a Minimal, Complete and Verifiable example. As a user you can learn tons of info from looking at the answers of already posted questions. In your case, I'd suggest you start trying to build something and as soon as you come across a concrete problem of which you cannot find the answer on SO, you post that as a question :). – Montmons

以上这段内容，是我在stackoverflow上提的一个问题，然后被扣了一分，然后这个扣分的人给我的评论。
我的问题是

[what I could do after 50 lines of python for building the tiniest blockchain?]

Several weeks ago,I read an article titled "Let's Build the Tiniest BlockChain In Less Than 50 Lines of Python"
https://medium.com/crypto-currently/lets-build-the-tiniest-blockchain-e70965a248b?hmsr=pycourses.com

we can create a new block with custom data based on previous block's hash.In this way,every block in the chain connected with each other. Thanks the author of this article for letting me who was a just beginner of programming understand what blockchain is. So,how should I put this into a easy application?Specifically,How to store those blocks?How to trace the relation between blocks? Could you recommend something related article?

我曾经一直疑惑一个问题：上网这么久，我发现西方社会的蠢货也很多，但是为啥他们能是发达国家，我想我现在有了部分的答案。就是他们搞技术的那部分人中，愿意去钻研细节的人比我们多太多。扣了分的人告诉我，问这种技术能干啥的问题没有意义，应该多去看看别人的问题。就好比现在很多人，连基础的高等数学知识都不想学，就急着去沾点人工智能、大数据的光。现在所谓的qq技术群和微信公众号，有太多太多就是为了蹭个热点售卖课程。当然我并不是反对知识卖钱，而是根本教不会学生这项技术到底能做什么，能解决怎样的问题。只是告诉他们知道这些高大上的名词，然后去面试浑水摸鱼。
