Where is the code that sends generated Bitcoins from mining to the wallet?


Short answer, but it really only scratches the surface:

The same process that is called "mining" also creates those Bitcoins. Meaning, you actually create them yourself but it can only done by solving a very difficult mathematical problem. The first one to solve that problem will get the reward. It is also important to mention that by solving of that mathematical problem the integrity of the Bitcon network is created (in terms of secure transactions). There some exchanges, like Mtgox, BTC-e, Kraken, to name only a few where you can exchange Bitcoin for real money though the process of actually getting the money to your banc account can be very lenghty. There are also also a few Bitcoin ATMs, for instance in Canada of Finland and there are also sites where you can find people in your area who are willing to exchange your Bitcoins for real money. This is hardcoded in the software used by the computers which creates the Bitcoin network. Roughly every 10 minutes, a new...

Which fragment of the Satoshi client is verifying if announced block has a valid reward?

I mean, we now live in the 25 BTC reward period. I guess client after receiving a newly minted block, does verifications, like checking if inputs and outputs are balancing for example, and, I guess, if the reward is 25 BTC, right?

So where is this fragment of the code?

I know where is the code which limits BTC supply to 21 million:

int64 static GetBlockValue(int nHeight, int64 nFees) { int64 nSubsidy = 50 * COIN; // Subsidy is cut in half every 210000 blocks, which will occur approximately every 4 years nSubsidy >>= (nHeight / 210000); return nSubsidy + nFees; }

...and I am looking for somebody to point me to the right place, where the verification is...

As I said in the comment above, you're talking about a service to manage actual money. Please don't offer this service to other people until you're sure it's working properly and it doesn't have security flaws.

You should try to make your wallet work with the Bitcoin Testnet first. The Testnet is a clone of the Bitcoin network that gets reset every once in a while. Therefore, its tokens are valueless. However, it allows you to experiment with your software and test functionality because it behaves like the Bitcoin network.

Now, depending on what your favorite programming language is, there are different libraries for Bitcoin already. If you're fine with Java, it is my understanding that bitcoinj is rather comprehensive and well-kept. There are also some open-source Bitcoin wallets already that use bitcoinj which you might use to inspire yourself how to solve some issues. One such wallet is the Bitcoin Wallet for Android.

From there, I suggest that you apply...

How Bitcoin Mining Works

Before you start mining Bitcoin, it's useful to understand what Bitcoin mining really means. Bitcoin mining is legal and is accomplished by running SHA256 double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. The speed at which you mine Bitcoins is measured in hashes per second.

The Bitcoin network compensates Bitcoin miners for their effort by releasing bitcoin to those who contribute the needed...

One of the most popular options for keeping your bitcoins safe is something called a paper wallet. Here we explain how to transfer all those digital coins into a physical paper form using just a printer.

Note that in this guide we’ll be talking about bitcoin. However, the basic concepts apply to any other cryptocurrency; for example, litecoin.

What is a wallet and why do I need one?

A bitcoin wallet consists of two ‘keys’. The one you’ll already likely be familiar with is the public key, which is your wallet address and is how other people send bitcoins to you.

The other part of your bitcoin wallet is the private key. It is this that enables you to send bitcoins to other people.

The combination of the recipient’s public key and your private key is what makes a cryptocurrency transaction possible.

It is important to understand that, if anyone else obtains the private key of your wallet, they can withdraw your funds – this is why it’s...

What is Bitcoin?

Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet. Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence.

Bitcoin is the first implementation of a concept called "cryptocurrency", which was first described in 1998 by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late 2010...

On a high level, the entire bitcoin network is built on the fact that all of the nodes are following the same rules. The rules state that whoever hashes the next block gets to mint a number of coins, so they can.

From the Bitcoin white paper:

By convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block. This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them.

From the wiki:

Bitcoins are created each time a user discovers a new block. The rate of block creation is approximately constant over time: 6 per hour. The number of Bitcoins generated per block is set to decrease geometrically, with a 50% reduction every four years. The result is that the number of Bitcoins in existence will never exceed 21...

Until Bitcoin becomes the dominant currency for payments around the world, it will be more popular among traders and price speculators. As a result, the price is subject to the market forces of supply and demand which, at this point in time, goes hand in hand with the trends and whims of speculators – as a result, the price can move suddenly and sharply up or down in response to news events.

As a rule of thumb: if a piece of news makes Bitcoin more likely to be widely adopted, the price rises. If it places extra hurdles towards mass adoption, the price will fall.

You can track all the latest Bitcoin price movements in real time with Bitcoin.com’s data charts, and convert the price to your local currency with our instant Price Converter.

These events may be based on issues affecting the Bitcoin world only – such as a large scale hack affecting a key Bitcoin exchange, wallet or essential software which causes the price to dip. This happened after the Mt. Gox...

In this example, a paper wallet is imported and swept using Blockchain.info’s web wallet service. First, you will need to open your Blockchain.info wallet account and navigate to “Import / Export”. If you don’t already have an account, you can sign up for free.

Navigate to the “Import / Export” tab.

Here you can either type or copy/paste the paper wallet’s private key (i.e. if you have used a stand-alone QR scanner) into the text box and press “Add Private Key”. Or click “Scan With Webcam” to scan the QR code using your webcam.

Choose what type of private key import you wish to perform.

Blockchain.info gives you the option to import or sweep the paper wallet. Please make sure you understand the difference. It’s generally recommend to sweep the paper wallet instead of importing it.

You’ll be prompted whether to import or sweep.

Once you complete this process you should see the entire paper wallet balance added to your Blockchain.info account...

Good news, perhaps, for bitcoin owners frustrated by Apple’s recent removal of Blockchain’s wallet app from its stores.

A service just launched promises to let people make bitcoin transactions via email, promoting itself as a solution that “works natively on the iPhone, and can’t be banned by Apple”.

The fully automated ‘Email Tip Bot’ is the product of developer Christian Genco, who also moonlights as a stage actor and speaker at TEDx events in Texas.

The Tip Bot functions as a standalone system, meaning that once bitcoins are there, they can be transferred around without the need for any wallet software.

Anyone who has experienced the process of giving or receiving bitcoin tips on reddit will be familiar with the way the Tip Bot works, as the transaction process is similar.

Bitcoin introduces newcomers to a lot of new concepts, but one concept in particular seems to be the hardest to grasp - you do not have any bitcoins in your “wallet”. When you buy bitcoins, nothing is sent to you, no special file or code.

That’s because - and here’s the concept to wrap your head around - there’s no such thing as a bitcoin. At least, not as some kind of individual object you can inspect in any way. Bitcoins only exist as transactions, which means that they only exist in the block chain, the record of transactions that every Bitcoin client has.

Let’s say Alice wants to buy a product from Carl that costs 100 bitcoins. Alice got bitcoins from earlier transactions. She generates a new transaction that references those earlier transactions (called the transaction inputs), which total 100 bitcoins, and sends them to Carl’s Bitcoin address (this is called the transaction output). Carl has been mining bitcoins and successfully generated an additional 50...
