Your article is very much educative and explanatory, as I given the opportunity to learn about what a hard fork and soft fork is all about and their differences. If you had asked me before now, I would a thought you are talking about a cutlery or a garden tool.
As good as your work is, you can make it better by applying the justification markdown style to align your work to make it neat and appealing and maybe some photos to illustrate your thoughts.
Overall, your explanations were on point, for that I wish you good luck my friend..
