How does the Bitcoin network work?

Bitcoin Digital Currency uses a cryptographic protocol called the proof of work which implies that more processing power is utilized to calculate the signature of each subsequent block than the previous block. Therefore, the total computing power required to hack into a system grows continuously. Consequently, it has become more profitable for the owner of this computing power to join the network rather than resist it. The disadvantage of the proof of work algorithm is a huge power consumption required for calculations. The Bitcoin system consumes as much electricity as a medium-sized European country per annum.

What are the nodes of Bitcoin?
