Bitcoin (BitCoin, BTC) is a digital currency implementation based on blockchain technology. The Bitcoin network is the first large-scale, long-tested digital currency system in history.
Since its official launch in 2009, Bitcoin's price has experienced multiple fluctuations, with the current market price exceeding $2,500 per BTC. The total number of blocks in the Bitcoin network is nearing 480,000.
Key Features of the Bitcoin Network
- Decentralization: No single entity can disrupt transactions—consensus among most participants is required.
- Anonymity: Account addresses are anonymous, making it difficult to link transactions to individuals (but complicating audits).
- Inflation Prevention: Bitcoin issuance occurs through mining, with supply halving every four years and capped at 21 million BTC.
