This page was last changed on 31 January mashable, at The wiki key is never shared, and allows the owner of the bitcoins to explains them.
Because addresses are pseudo-anonymous, anyone can have as many addresses as they want. A backup of a wallet prevents 'losing' the bitcoins. It's hard to deny that Bitcoin is changing the way we use money, and our concept of how currency should work. The first miner or group of miners to solve the particular puzzle are rewarded with new bitcoins. Courtesy of Silicon Angle; Blockchain. Bitcoin uses QR codes because they can store a lot of information in a small space, and a camera such as a smartphone can read them. Ever wonder how Bitcoin and other cryptocurrencies actually work?
The first bitcoin or group of miners to solve the particular puzzle are rewarded with new bitcoins. Much of the attention Bitcoin explains is because of its connection to illicit activity, most notably the online drug marketplace, Silk Road. All transactions can take wiki solely from peer to peer, but a number of sites exist to make mashable transactions simpler. These sites are called exchanges. It is also possible to get a Bitcoin address using an account at an exchange or online wallet service.
One of the differences between using bitcoin and using regular money online is that bitcoin can be used without having to link any sort of real-world identity to it.
Unless someone chooses to link their name to a bitcoin address, it is hard to tell who owns the address. Bitcoin does not keep track of users; it keeps track of addresses where the money is.
Each address has two important pieces of cryptographic information, or keys: The public key, which is what the "bitcoin address" is created from, is similar to an email address; anyone can look it up and send bitcoins to it. The private address, or private key, is similar to an email password; only with it can the owner send bitcoins from it. Because of this, it is very important that this private key is kept secret.
To send bitcoins from an address, you prove to the network that you own the private key that corresponds to the address, without revealing the private key. This is done with a branch of mathematics known as public key cryptography. A public key is what determines the ownership of bitcoins, and is very similar to an ID number.
If someone wanted to send you bitcoins, all you would need to do is supply them your bitcoin address, which is a version of your public key that is easier to read and type.
Anyone using the system can see how much money "ABC" has and how much money "DEF" has, but they cannot tell anything about who owns the address. But Bob and Alice each have a second key which only they individually know. This is the private key, and it is the "other half" of a Bitcoin address.
The private key is never shared, and allows the owner of the bitcoins to control them. However, if the private key is not kept secret, then anyone who sees it can also control and take the bitcoins there.
The person who took it, told others about it later, saying "I'll send it back once Matt gives me a new address, since someone else can sweep [empty] out the old one. Sites or users using the Bitcoin system are required to use a global database called the blockchain.
The blockchain is a record of all transactions that have taken place in the Bitcoin network. It also keeps track of new bitcoins as they are generated. With these two facts, the blockchain is able to keep track of who has how much money at all times.
To generate a bitcoin, a miner must solve a math problem. However, the difficulty of the math problem depends on how many people are buying bitcoin at the moment. Because of how complicated the math problems usually are, they must be calculated with very powerful processors.
The process of generating the bitcoins is called mining. People who use these machines to mine bitcoins are called miners. Miners either compete with one another or work together in groups to solve a mathematical puzzle. The first miner or group of miners to solve the particular puzzle are rewarded with new bitcoins.
The puzzle is determined by the transactions being sent at the time and the previous puzzle solution. This means the solution to one puzzle is always different from the puzzles before. Attempting to change an earlier transaction, maybe to fake bitcoins being sent or change the number of someone's bitcoins, requires solving that puzzle again, which takes a lot of work, and also requires solving each of the following puzzles, which takes even more work.
This means a bitcoin cheater needs to outpace all the other bitcoin miners to change the bitcoin history. This makes the bitcoin blockchain very safe to use. Mashable is for superfans.
