Developing a Wallet?

Obviously, you'll need programming experience to develop a new wallet. Which language you choose to write it in would be up to you, of course.

It is probably better to try and contribute to an open source wallet that already exists than to try and create your own from the ground up though. Not sure there is really a need for more wallets at this point.

We already have enough desktop wallets for the moment , If you want to build something then I suggest targeting phone and web wallets since we don't have that much and If we do , they definitely need improvements.
Unless you know what you are doing and you have the required years of programming experience and security , Its not really a good idea to stop making a wallet , at least not for public use.

Actually, what I want to know is the working logic of wallets. For example new altcoins are coming out. Different wallets are being developed for these altcoins.
Is it like the bitcoin wallets in the logic of the wallets developed for the new altcoins?

A wallet has to follow the protocol and consensus of whatever network and coin it is using. It has to be able to connect to nodes on the network and then send and receive messages to and from the connected nodes. It then has to be able to validate blocks and transactions according to the rules of whatever network and coin it is for.

A wallet also has to have some way to securely store private keys and then be able to use those private keys to sign things (usually transactions). It also has to know how to build transactions and how to sign them.

The actual details for how a wallet works varies from coin to coin as different coins use different technologies and specifications.

Well technically you could make a wallet on top of the RPC protocol and run the RCP cli in the background. This way you'd only need a GUI which isn't that hard to implement.

Depending on the amount of detail of the logic you want, looking at the source code of some open source wallets might be your best bet.

all features that we need to develop is to be more trusted and fully secure the walllets and do what they say and don't run away our money so that people didn't have any problem about it saving or storing they're money on to it.

I think you need to pursue other open source work and make some adjustments or add some helpful features in it. Also you need some security measures in it. If you are a skilled programmer, you know what to do. But if you don't have any idea on programming at all. Just proceed another projects. Bitcoin wallets need a lot of programming to be called a safe wallet or safer wallet.

As far as I understand it, I need a serious knowledge and experience in programming to develop wallet. It does not seem like a job that ordinary programmers can do.

Which technologies do we need to know? As far as I know bitcoin networks are working with p2p logic. So the programmer who develops the wallet needs to have the network information.

Finally, what programming languages do we need to know to develop your wallet? Can we develop with any programming language?

very important

I am also interested in this so I am going to try and answer and hope others correct me and add more info.

Yes, because we aren't talking about a simple tool, a bitcoin wallet deals with other people's money and the security aspect of it becomes paramount.

Which technologies do we need to know? As far as I know bitcoin networks are working with p2p logic. So the programmer who develops the wallet needs to have the network information.

Cryptography I think is the most part and most important part of it, and then it is network and connecting to nodes, knowing and following the network consensus, saving blockchain and read/write to it.

Finally, what programming languages do we need to know to develop your wallet? Can we develop with any programming language?

Any programming language should do.
Bitcoin Core is written mostly in C++
Electrum is mostly Python
Multibit is Java
Armory is mostly C++ and Python
Greenaddress is Shell and Javascript and HTML
mSignia is C++
mycelium is Java
breadwallet is Objective C
BitAddress is JavaScript and HTML

I have not yet seen C♯, Ruby, PHP, Go, C

Today, for a person I don't think developing a wallet is a good idea, Only A big company should do it, you won't get any trust by bitcoin users
since they're facing a lot of scams and trust is now a huge problem.

Anyway take a look on Electrum open source project, You need to have goods skills in Python.

In fact, programming languages are a tool. If it can be written in languages such as Java, Python, and JavaScript, it can be written in any language. But each of the topics you talk about requires special expertise.

As Bitcoin_BOy$ said, there is also a trust part. Even if the individual wallet is developed, it must be accepted by the bitcoin community.

Actually I don't agree with the trust part. Trust is earned over time, if any developer gives up because he has no history and no trust, development is over.
Also everything is open source and if it is good, it will get peer reviewed, you can see this on GitHub in the number of "Stars" and "watchers" and "contributors" and some other stuff.

Yeah, everyone may not trust a new wallet initially until others have had the time to inspect and audit the code, but this shouldn't discourage development. Trust comes with time and if the software is built well, you should be able to gain trust after some time as long as the code is open source.

Yes it is difficult for a new wallet to get the trust of many people, and it was reasonable in my opinion. I am very agree with you say that the trust will be built come with time and development wallet. To develop a new wallet I think it might be better if it focused on the development of security. Because if the security on wallet growing and increasingly secure, I'm sure many people will begin to believe and use the wallet.

[stardustin]

Nowdays there are so many bitcoin wallets which are safer and it's waste of time if you are going to built one wallet alone and that's hard doo. You need to know porgramming language, mostly c++ but also you can to write wallet in another language but I advice you c++

[saqibmunir]

there are many online wallet for bitcoin and there is no need to create new one but of course for developing a wallet you have to expert in a certian programming language you use it for making a wallet.........
