Bitcoin is a digital currency which operates without any central control or supervision of banks or governments. Instead, it relies on peer-to-peer software and cryptography. A public ledger records all bitcoin transactions and copies are kept on servers around the world. Anyone with a spare computer can set up one of these servers, known as a node. Consensus on who owns which coins is achieved cryptographically across these nodes rather than relying on a central source of trust like a bank. Every transaction is publicly broadcast on the network and shared from node to node. Every ten minutes or so these transactions are collected together by miners into a group called a block and permanently added to the block chain .
This is the ultimate bitcoin ledger. In the same way that you would Job Function Email Database store traditional currencies in a physical wallet , virtual currencies are held in digital wallets and can be accessed by client software or a variety of online and hardware tools. Bitcoins can currently be divided to seven decimal places: one thousandth of a bitcoin is known as a milli and one hundredth of a bitcoin is known as a satoshi. There really is no such thing as a bitcoin or a wallet, only agreements between the network for the ownership of a coin. A private key is used to prove ownership of funds on the network when you make a transaction. A person can simply memorize his private key and does not need anything else to receive or spend his virtual money, a concept known as a "brain wallet". Can bitcoin be converted to cash? Bitcoin can be exchanged for cash just like any asset. There are many online cryptocurrency exchanges where people can do this, but transactions can also be done in person or over any communication platform , allowing even small businesses to accept bitcoins.
There is no official mechanism built into bitcoin to convert it to another currency. What is the purpose of bitcoin? Bitcoin was created as a way for people to send money over the internet. The digital currency was intended to provide an alternative payment system that would operate without central control, but would otherwise be used just like traditional currencies. Are bitcoins safe? The cryptography behind bitcoin is based on the SHA-256 algorithm created by the US National Security Agency. Breaking this is, for all intents and purposes, impossible since there are more possible private keys that would need to be tested (22 56 ) than there are atoms in the universe (estimated to be somewhere between 10 78 and 10 82 ). There have been several high-profile cases where bitcoin exchanges have been hacked and funds stolen, but these services have consistently held the digital currency on behalf of customers. What was hacked in these cases was the website and not the bitcoin network. In theory, if an attacker could control more than half of all bitcoin nodes in existence, then they could create a consensus that they owned all the bitcoins and enter it into the blockchain.
