Despite it not being legal tenderBitcoin charts high on popularity, and has triggered the launch of hundreds of other virtual currencies collectively referred to as Altcoins. Understanding Bitcoin Bitcoin is a collection of computers, or nodes, that all run Bitcoin's code and store its blockchain. A blockchain can be thought of as a collection of blocks.

In each block is a collection of transactions. Because all these computers running the blockchain have the same list of blocks and transactions and can transparently see these new blocks being filled with new Bitcoin transactions, no one can cheat the system.

Anyone, whether they run a Bitcoin "node" or not, can see these transactions occurring live.

Bitcoin has around 47, nodes as of May and this number is growing, making such an attack quite unlikely. Balances of Bitcoin tokens are kept using public and private "keys," which are long strings of numbers and bitcoin global computer linked through the mathematical encryption algorithm that was used to create them.

The public key comparable to a bank account number serves as the address which is published to the world and to which others may send bitcoins. Bitcoin keys should not be confused with a Bitcoin wallet, which is a physical or digital device which facilitates the trading of Bitcoin and allows bitcoin global computer to track ownership of coins. The term "wallet" is a bit misleading, as Bitcoin's decentralized nature means that it is never stored "in" a wallet, but rather decentrally on a blockchain.

In contributing to the blockchain, mining adds and verifies transaction records across the network. For adding blocks to the blockchain, miners receive a reward in the form of a few bitcoins; the reward is halved everyblocks.

The block reward was 50 new bitcoins in and is currently On May 11th, the third halving occurred, bringing the reward for each block discovery down to 6.
