Ethereum (ETH) is a groundbreaking blockchain platform that was introduced in 2013 by its founder, Vitalik Buterin and was official launched in 2015. Unlike Bitcoin, Ethereum doesn't have a fixed supply, making it a highly adaptable ecosystem. It empowers the creation of smart contracts and decentralized applications (DApps), with faster block generation and improved scalability, earning it the nickname "Blockchain 2.0."
 
ETH, the native cryptocurrency of Ethereum, plays a pivotal role in transactions and services within the network. Ethereum's concept of smart contracts has attracted developers and projects, enabling trustless and automated agreements. Ethereum has transitioned from the energy-intensive Proof of Work (PoW) to the more efficient Proof of Stake (PoS) consensus mechanism, which significantly reduces energy consumption and improves scalability.
