Bitcoin (BTC) is a revolutionary virtual currency that operates on a decentralized peer-to-peer (P2P) payment system, free from centralized control by governments or entities. Created in 2008 by the anonymous individual or group known as Satoshi Nakamoto, Bitcoin has become the cornerstone of the digital asset industry.
Although not technically the first cryptocurrency, Bitcoin and its innovative blockchain technology are widely regarded as the catalysts for today's thriving digital asset ecosystem. Currently, Bitcoin holds the largest market capitalization among cryptocurrencies.
How Does Bitcoin Work?
Bitcoin is entirely digital, functioning on a decentralized blockchain network—a public virtual ledger that records all transactions. Transactions are broadcast to nodes for validation. Once confirmed, they are grouped into blocks and added to the blockchain through a process called Proof of Work (PoW), which secures the network.
Key Features:
- Immutability: The blockchain ledger cannot be altered or deleted.
- Transparency: Anyone can access the ledger, making it an open blockchain.
- Anonymity: Transactions can be conducted privately, ensuring both privacy and transparency.
- Decentralization: Bitcoin can be traded freely via P2P trading without intermediaries.
Who Created Bitcoin?
Bitcoin was conceptualized by Satoshi Nakamoto in response to perceived flaws in traditional banking systems. Launched shortly after the 2007–2008 global financial crisis, Bitcoin’s purpose was outlined in the whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System. Its mission: to democratize finance by eliminating reliance on centralized banks.
