Bitcoin Core

Bitcoin Core is the software implementation of the Bitcoin network and the original client program of the Bitcoin protocol. Released by Satoshi Nakamoto in 2009, Bitcoin Core serves as the benchmark for Bitcoin node software and enables the decentralization of the Bitcoin network.

Bitcoin Core's software is known for its stability and security. By validating and propagating transactions, Bitcoin Core ensures the integrity of the blockchain. Each node runs Bitcoin Core software and can independently verify the blockchain, enhancing the decentralization and security of the network.

Bitcoin Core is more than just a wallet, it contains the complete history of Bitcoin transactions. Users can download the entire blockchain, which allows users to verify all transactions completely independently, although this requires large storage space and computing power.

Bitcoin Core uses advanced encryption technology to protect user assets. Each transaction is signed by a private key, and only users who hold the corresponding private key can spend Bitcoin. Through the SHA-256 hash algorithm, Bitcoin transactions are irreversible, ensuring transaction security.

Bitcoin Core uses a peer-to-peer (P2P) network structure, which means there is no central server and every node is equal. This structure makes the Bitcoin network more censorship-resistant and less vulnerable to attacks.

The consensus mechanism is key to the core of Bitcoin. Through Proof of Work (PoW), miners compete to decipher mathematical puzzles to generate new blocks. This process both secures the blockchain and issues new Bitcoins as rewards.

The development of Bitcoin Core is carried out by a global open source community. This community includes many leading cryptography experts and software developers who continuously improve the software through collaboration and review to adapt to changing needs and challenges.
