#AirdropSafetyGuide Ethereum (ETH) is a decentralized blockchain platform that enables the creation of smart contracts and decentralized applications (dApps). It was proposed by Vitalik Buterin in 2013 and launched in 2015. Unlike Bitcoin, which focuses on monetary transactions, Ethereum allows for code execution on its network, making it a kind of "world computer." Its native cryptocurrency, Ether (ETH), is used to pay fees for transactions and execute contracts. Ethereum has driven innovations such as decentralized finance (DeFi) and non-fungible tokens (NFTs). In 2022, it migrated to a Proof of Stake consensus system, improving its energy efficiency.
