Bitcoin network

Bitcoin network is a decentralized digital currency network that enables peer-to-peer transactions without the need for intermediaries like banks. It operates on a technology called blockchain, which is a distributed ledger that records all transactions across a network of computers.

Here’s a breakdown of its key components:

1. Blockchain: This is a distributed ledger that records all Bitcoin transactions. It consists of a chain of blocks, each containing a list of transactions. Each block is linked to the previous one, forming a chronological chain.
2. Nodes: These are computers connected to the Bitcoin network that maintain a copy of the blockchain. Nodes validate and relay transactions, ensuring that all transactions comply with the network’s rules (consensus rules).
3. Miners: Miners are nodes in the network that compete to solve complex mathematical puzzles to validate transactions and add them to the blockchain. They are rewarded with newly created bitcoins and transaction fees for their efforts.
4. Wallets: Bitcoin wallets are software applications that allow users to store, send, and receive bitcoins. Each wallet contains one or more pairs of public and private keys, which are used to sign and verify transactions.
5. Consensus Mechanism: The Bitcoin network relies on a consensus mechanism called Proof of Work (PoW), where miners compete to solve mathematical puzzles to validate transactions and create new blocks. This process ensures the security and integrity of the network.

Overall, the Bitcoin network enables secure, transparent, and censorship-resistant transactions, offering an alternative to traditional financial systems.
