is a blockchain-based platform that goes beyond being just a digital currency — it enables smart contracts and decentralized applications (DApps). It is considered the second most popular and valuable cryptocurrency after Bitcoin. The main advantage of Ethereum is that developers can build and launch their own projects and applications without relying on any centralized authority. Its native token, Ether (ETH), is used for transactions and to pay network fees (known as gas fees). Today, Ethereum serves as the backbone of decentralized finance (DeFi), NFTs, and Web3 technologies, making it a fundamental part of the future digital economy.
