How Bitcoin Works as a Decentralised Digital Currency

Bitcoin works as a decentralized digital currency by utilizing advanced technology, known as blockchain, to record, store, and verify all financial transactions. This means that there is no central authority, such as a government or bank, controlling the currency. Instead, the Bitcoin network is maintained and operated by a vast network of users known as 'miners'.

The Bitcoin network is made up of thousands of nodes, which are computers running the Bitcoin software. Each of these nodes holds a copy of the blockchain and works together to validate transactions and maintain the network's integrity.

An important aspect of Bitcoin's decentralisation is its limited supply. Bitcoin has a fixed supply of 21 million coins. This scarcity is achieved through a process called 'mining', where miners use powerful computers to solve complex mathematical problems and verify transactions. As an incentive for their work, miners are rewarded with newly created bitcoins.
