The decentralized bitcoin exchange
Coinffeine is an open source, peer-to-peer (P2P) bitcoin exchange podium. With Coinffeine you are able to buy and sell bitcoins securely and anonymously without having to rely on a centralized exchange. It’s like BitTorrent for your bitcoins!
Coinffeine is the next-gen bitcoin exchange, with a dramatically different treatment than traditional exchanges. Wij exploit the total potential of the bitcoin protocol to give you the most secure, private and reliable podium te the market.
You are always ter control of your bitcoins and your trusted payment processor of choice is te control of your local currency.
The exchange is done peer-to-peer (P2P), so there is only a very limited disclosure of information (your payment processor account so the money can be transferred) with the person you are doing the exchange.
Coinffeine is totally distributed, just like BitTorrent, so even if our server is overcharged, gets hacked or explodes it won’t affect the network and the exchange can proceed to work without it being affected.
Unlike traditional exchanges, you receive your bitcoins directly to your wallet and your local currency directly to your payment processor’s account, so you can begin spending them spil soon spil the exchange is finished.
Coinffeine is a distributed exchange. This means wij have less operational cost which results te less fees. For now, Coinffeine will not charge any toverfee at all, you only need to pay the standard bitcoin transaction toverfee plus any fees your payment processor might charge you.
Our code is open to inspection, audit and review by anyone to ensure that Coinffeine is trustworthy. Wij accept bug reports and patches from the community to ensure the highest level of quality.
Coinffeine works by using Bitcoin’s own features to enable a secure way of exchanging bitcoins with an untrusted peer without the need for a centralized trusted third party. Check out the below presentation for a high level overview of how exchanges are performed.
Want more informatie on how it works? Check out our in-depth technical wiki and the detailed description of the zero trust exchange algorithm.
Coinffeine is open source software and contributions te the form of terugkoppeling, code or ideas are welcomed and encouraged.

What open source miner applications are there?
What open source miner applications are there? Especially to see how the mining process works.
jzgarzik wrote a very basic miner ter Python. It is slow on purpose, because it shows how a plain miner works (and the mining process). It can also be reused spil boilerplate code (the getwork JSON-RPC directive).
The official list is on The Wiki and is permanently being modified since fresh software shows up fairly often, but here’s the quick breakdown:
- Poclbm – Python/OpenCL GPU miner (GUI)
- DiabloMiner – Java/OpenCL GPU miner (MAC OS X GUI)
- RPC Miner – remote RPC miner (MAC OS X GUI)
- Phoenix miner – miner
- Cpu Miner – miner
- Ufasoft miner – miner
- Pyminer – Python miner, reference implementation
- Remote miner – mining pool software
- Open Source FGPA Bitcoin Miner – a miner that makes use of an FPGA Houtvezelplaat
Poclbm and Phoenix are most likely the most popular (linksaf go to the sources) tho’ that’s based more on my opinion than any facts or studies. Te either case, both should shed some light on the mining process.
The most visible open-source mining application is the official Bitcoin client itself, available at: https://github.com/bitcoin/bitcoin
The source code is well written and shows fairly clearly the way that hashing is performed ter order to mine fresh blocks. It is however a CPU-only algorithm, and doesn’t use some of the more advanced mechanisms for accelerating the hashing process.
Despite this, it undoubtedly offers a good introduction into how the generation of blocks, hashing etc. works, without the added overhead of having to overeenkomst with potentially unacquainted GPU-based mining code, which is intentially very optimised and spil a result will likely to be more difficult to understand, and make the basic concepts more difficult to go after.
Phoenix is a very good GPU miner. While I couldn’t find the precies license, it’s source is available on GitHub: https://bitcointalk.org/index.php?topic=6458.0
Well, it’s written te python, so you could see the source anyways. However, it’s actually fairly effortless to understand and modify, e.g. to create your own logging interface.
Written te scala, mostly just mining device control for connecting with pools
Poclbm: An open source, python based GPU miner.
Open Source FPGA Miner: The name says it all. Klapper the source for the project.
