What Is BitCoin
Bitcoin was the first popular cryptocoin. No one knows exactly who created it—most cryptocurrencies are designed for maximum anonymity—but bitcoins first appeared in 2009 from a developer supposedly named Satoshi Nakamoto. He has since disappeared and left behind a Bitcoin fortune.
How BitCoin Work
A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet.
