Bitcoin is a digital currency that, unlike other currencies, is not printed and generated by central banks, but is computed and managed by many people in a distributed manner. Bitcoin is not just the currency but also the name of a booking system and a cryptographically legitimized allocation of work and computational cost. Bitcoin as a digital currency is not subject to governmental or central control.
After Bitcoin, Ethereum (ETH) is the best-known cryptocurrency and combines the benefits of blockchain with automatically executable and programmable action chains, so-called smart contracts.
Satoshi Nakamoto is the inventor of the Bitcoin cryptocurrency. What’s certain is that the name Satoshi Nakamoto is a pseudonym. But it is still unknown which person or group stands behind it. In 2008, he published the Bitcoin white paper and the first version of the Bitcoin core via an encrypted e-mail.
