Bitcoin Forum

I have a question that i always ask myself, in case bitcoin has an error or a possible improvement who would correct it?

You can read about bitcoin improvement proposal (https://github.com/bitcoin/bips). It has been used for error fixing and improvements in the past with each beginning from a proposal.

Literally anyone.

There is an error related problem? Someone can post the issue directly, and if they have programming skills, they can fix it by themselves and then request to make the fix getting merged into the main bitcoin codebase.

So does improvement, anyone can straightly suggest an improvement on this forum or anywhere within bitcoin-related discussion places, for example, as listed on https://www.lopp.net/bitcoin-information/discussion-forums.html. One of the Bitcointalk members also discussed their improvement proposal here (https://bitcointalk.org/index.php?topic=5410553.msg60786039).

At the end of the day, the fix or improvement request will be thoroughly reviewed by the community.

For an explanation of how the process works, refer to "Decision Making" Process (https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md#decision-making-process), and read until "Finding Reviewers".

I think everyone. Its an open source so anything that could improve the bitcoin network could do that. A lot of developers are open for suggestion and proposals. There are lots of things to do but this will be a good quorum to check out whats best for bitcoin.

As many have already correctly pointed out, in the case of open-source software, any skilled programmer can present their version of a fix to a newly-discovered bug or error by making a pull request. But you don't have to be a skilled programmer or a person able to read and understand code to find a bug in the software. If, upon interacting with bitcoin, you encounter a problem never before seen, you can open an issue on GitHub or a similar platform, where you will describe an error and all the steps that lead to that error. This way, you can help developers to find a solution to the problem. It is also important to note that some errors in bitcoin cannot be fixed except through making a hardfork, that is, making bitcoin incompatible with current nodes' software. This kind of bug remains unfixed because their fix may be more harmful than the errors themselves.

First lets clarify the difference between Bitcoin protocol and Bitcoin software.

There are lots of Bitcoin softwares like bitcoin core, Electrum, Trezor (firmware), bitaddress,... These tools can have bugs and errors. Since they are open source anybody can find the bug and fix it and then share it with the community, otherwise you have to report it to the developers of that software to get them to fix it.

The Bitcoin protocol on the other hand is just a set of rules, they don't have "errors" as you put it. It can have security flaws but since the protocol is old and is rigorously reviewed and tested it does not have any security flaws. But if any were to be found they have to be reported only to the reference implementation team (bitcoin core) to be discussed and fixed appropriately similar to how the new features are added.

This is a very interesting question, which the developer are the one can answer it correct, but in other hand bitcoin platform has been created in a way that no one can interrupt, or fixed by someone, which has already programmed in advance.

The answer is that "we all" correct it. While it may be a single developer that submits new code, it is up to the bitcoin nodes to decide to actually run the new code.

That's one of the most beautiful things about Bitcoin. We don't rely on anybody. We rely on everybody.
