$BNB is one of the most popular and widely used cryptocurrencies, known for its smart contract functionality and decentralized applications (DApps). Launched in 2015 by Vitalik Buterin, Ethereum introduced a blockchain that goes beyond simple transactions, allowing developers to create and deploy complex programs. Unlike Bitcoin, which primarily serves as digital gold, Ethereum powers an entire ecosystem of decentralized finance (DeFi), non-fungible tokens (NFTs), and other Web3 innovations. With its transition to Ethereum 2.0 and the Proof-of-Stake (PoS) consensus mechanism, Ethereum has become more energy-efficient and scalable. Its native cryptocurrency, ETH, is essential for transaction fees, staking, and governance within the network.
