How does Bitcoin work?
Each bitcoin (trading symbol “BTC,” though “XBT” is also used) is a computer file stored in a digital wallet on a computer or smartphone. To understand how the cryptocurrency works, it helps to understand these terms and a little context:
Blockchain: Bitcoin is powered by open-source code known as blockchain, which creates a shared public ledger. Each transaction is a “block” that is “chained” to the code, creating a permanent record of each transaction. Blockchain technology is at the heart of more than 10,000 cryptocurrencies that have followed in Bitcoin’s wake.
