How does Bitcoin work

Bitcoin introduced a type of currency (called cryptocurrency) that can be created and tracked on a public ledger (called blockchain), and which is not controlled by any central authority like a company or a country. Unlike with traditional currencies, everyone who can contribute the computational power needed to maintain this network will keep a record of every single Bitcoin transaction. In return, these participants will be able to gain Bitcoin by mining, which is the process of validating transactions being added to the ledger by solving complex puzzles. This is called the proof of work (PoW) consensus algorithm.
