Ethereum
Ethereum is one of the most important blockchain platforms in the cryptocurrency industry and the second-largest cryptocurrency ecosystem after Bitcoin. Proposed in 2013 by Vitalik Buterin and officially launched in 2015, Ethereum was designed to do more than simply transfer digital money. It introduced the concept of smart contracts - programmable agreements that automatically execute when certain conditions are met. This innovation made it possible for developers to build decentralized applications, also known as dApps, directly on the blockchain.
Ethereum’s native cryptocurrency, Ether (ETH), is used to pay transaction fees and power applications across the network. Over the years, Ethereum has become the foundation for major innovations in blockchain technology, including decentralized finance (DeFi), NFTs, blockchain gaming, and decentralized autonomous organizations (DAOs). The network has also evolved technologically, moving from Proof-of-Work to the more energy-efficient Proof-of-Stake consensus system.
Today, Ethereum supports thousands of projects and millions of users worldwide, playing a major role in shaping the future of decentralized technology and digital finance.

Layer 1 vs Layer 2 Explained
Blockchain networks are designed to let people transfer value, run applications, and interact with digital assets without relying on a central authority. But as more people use a blockchain, the network can face an important challenge: how can it process more activity without becoming slow, expensive, or overly centralized?
