What is Bitcoin ?
Bitcoin is the oldest and most popular cryptocurrency, which enables a decentralised payment-system for goods and services.
BTC uses the blockchain-technology to enable a decentralised payment-system without the need of banks or other financial-institutions. For every Bitcoin-transaction, encrypted hash-codes get digitally exchanged across the peer-to-peer network of the bitcoin-community. The blockchain, which is a continuously growing list of transaction-records (blocks), monitors and verifies the transfer of Bitcoins between users. The compute-intensive progress of processing all the transaction-data (blocks) is made by miners all over the world. The miners get a little amount of bitcoins for processing the transactions. So there is no need to trust in financial institutions like banks. The bitcoin-community and its decentralised system controls the money by itself.
Each user’s Bitcoins are stored in a program called digital wallet, which also holds each network-address the user sends and receives Bitcoins from, as well as a private key known only to the user and required as key for secure money-transfer.
