Bitcoin is a decentralized digital currency proposed by Satoshi Nakamoto in 2008 and officially launched in 2009. It is the world's first successful cryptocurrency, operating on blockchain technology, aimed at creating a peer-to-peer electronic cash system without relying on traditional financial institutions or central authorities.
The core technology of Bitcoin is blockchain, which is a distributed ledger technology. The blockchain consists of a series of blocks linked in chronological order, each containing multiple transaction records. These blocks are linked together using cryptographic methods, ensuring data immutability and transparency. The Bitcoin network is maintained by nodes around the world, each holding a complete copy of the blockchain to ensure the system's decentralization and security.
The total supply of Bitcoin is limited, capped at 21 million coins. This scarcity design gives Bitcoin anti-inflation characteristics. Bitcoin is issued through a process called 'mining,' where miners validate transactions and create new blocks by solving complex mathematical problems. As a reward, miners can receive newly generated Bitcoins and transaction fees.
Bitcoin transactions are characterized by anonymity and global reach. Users only need a Bitcoin wallet address to transact, without providing personal identification information. Transaction records are publicly transparent, but users' identities are hidden, protecting privacy. Additionally, Bitcoin transactions are not limited by national borders and can be completed quickly worldwide, with relatively low transaction fees.
Despite its many advantages, Bitcoin also faces some challenges. Its price is highly volatile and speculative, leading to insufficient stability as a payment tool. Moreover, the energy consumption of Bitcoin mining has raised concerns, as the process requires substantial computational resources, impacting the environment.
Overall, Bitcoin, as an innovative financial tool, has driven the development of blockchain technology and sparked widespread discussions globally about currency, financial systems, and decentralized technology.
