Bitcoin achieves decentralization in its network through the use of a distributed ledger called the blockchain. This blockchain is maintained by a network of nodes (computers) that participate in the validation and verification of transactions. By using a consensus mechanism called Proof of Work (PoW), miners compete to solve complex mathematical problems to add new blocks to the blockchain, ensuring that no single entity has control over the network. Additionally, the open-source nature of Bitcoin allows anyone to run a node, further enhancing the decentralization of the network.
