With the introduction of crypto money and blockchain concepts, we have been hearing a lot of "Hard Fork" and "Soft Fork" concepts lately. We do not know very clearly the answer to the question "What is Soft Fork and Hard Fork?" By clarifying the concepts, I will try to reveal the differences between them.
What is Fork?
This "fork" concept is a concept that unfortunately we can not find a proper Turkcevel. It's called a pussy, but I do not think it's a good translation. My ear is more appropriate than "differentiation". The concept of fork is a term for which software is familiar. Forking is a new project that goes a different way, starting from the source code of a project. Open source code is quite visible in their projects. If the work you want to do is not done with the current project, but the features that will give you the start are in that project then you can start your own project by making that project "fork". The concept of "Soft Fork and Hard Fork" came out with the crypto money miner.
Why do you fork / break in the crypto currency?
As you know, bitcoin (and sub-coin) mining rules are rules that everyone knows and complies with. Mining is done within these rules. What happens if some of the best miners are willing to change these rules? Since these structures are distributed and they are not centrally controlled, they can not proceed with the decision of a small and competent team. If the request for amendment collects a mass of supporters, a new "fork" will be announced and rules will be introduced from this name. Well, a question might come to mind:
"Can I make a" fork "if there is no central authority?" The answer is "yes". Anyone can do it. But the majority of the community must accept your consultation in order for the miners to follow you and comply with your rules. This also requires that you know very well what you are doing and that there is a significant increase in your attendance. For this reason some separations may be accepted, while others may fail.

The use of rules introduced by a decomposition should certainly provide an advantage to miners. At this point, the miners are striving to pass new decomposition quickly. If the new separation is not successful enough, there will be division in the community; this crypto is a very dangerous situation for money. Now let's go to the definitions of Soft Fork and Hard Fork.
What is Soft Fork?
In the shortest sense, "backward compatible" decomposition can be called "soft fork / soft decomposition". Blocks produced according to the old rules also apply to new rules. Thus, the system can continue without breaking backwards. Continue with a single chain and your pawn with a blot that was created in the past can change hands according to the new rules. After a certain amount of time, the majority of the network passes through the new splitting and the "fork" is successfully completed.
What is Hard Fork?
As the name implies, "hard fork" is the name given to the decomposition, which can not be reconciled. In this breakdown, a block created according to the old rules is valid only in the old version. The same applies to the new version. So after decomposition, two separate chains come to the square and there is no interaction between them. This method is of course not a preferred method. This sort of decomposition is done if it really becomes compulsory. Because the risk of dividing the communities I have outlined above is higher, it needs to be decided well.
What are the effects of Fork?
Such separations have significant effects. First of all, new rules mean new code to write. This is also the business of all the miners software. Of course, the markets that are formed on these currencies are directly affected by these changes.
These changes create uneasiness in the market. For example, we will see how Bitcoin Fork will be met on 1 August 2017. But when I look at quora, everybody is asking dozens of questions in the style of "Should I sell my bitcoins?", "Do I lose bitcoins at my fingertips?"
In addition, some transactions may disappear as transactions continue during these exchanges. It is also the most disastrous situation that can be found in a new incoming change. Coin leaks may also occur on this site.
Soft Fork and Hard Fork
I tried to give information about "soft fork" and "hard fork". I hope it's useful.
