Decentralisation refers to the distribution of control over a blockchain network. The primary goal of decentralisation is to increase blockchain network functionality by eliminating the need for a centralised authority. For example, the bank institution is the central authority in traditional banking. It manages the transfer of funds and may impose conditions like overdraft fees. In a decentralised financial system like Bitcoin, no authority is needed to confirm and process transactions. Instead, Bitcoin miners sustain the network by solving complex mathematical equations to verify transactions.
