Introduction to Bitcoin and Ethereum
Bitcoin, introduced in 2009 by the anonymous developer(s) known as Satoshi Nakamoto, is the first decentralized cryptocurrency built on blockchain technology. It enables peer-to-peer transactions without intermediaries through a consensus mechanism.
Ethereum, launched in 2015, is more than just a cryptocurrency—it's a platform for decentralized applications (dApps) powered by its native token, Ether (ETH). Unlike Bitcoin's singular focus on payments, Ethereum introduced smart contract functionality, revolutionizing blockchain utility.
Key Differences Between Bitcoin and Ethereum
