Introduction
Ethereum (ETH), the second-largest cryptocurrency by market capitalization after Bitcoin, is more than just a digital currency—it is a decentralized platform that has revolutionized how applications are built and deployed on the blockchain. Launched in 2015 by Vitalik Buterin and a team of developers, Ethereum introduced the world to smart contracts, laying the foundation for the decentralized finance (DeFi) and non-fungible token (NFT) booms.

What Is Ethereum (ETH)?
Ethereum is a blockchain-based platform that enables developers to build decentralized applications (dApps) using smart contracts—self-executing agreements with the terms directly written into code. ETH is the native cryptocurrency of the Ethereum network, used to pay for transactions and computational services.

Key Features of Ethereum
1. Smart Contracts:
Smart contracts automate processes without the need for intermediaries, reducing costs and improving efficiency across industries.
2. Decentralized Applications (dApps):
Developers can build dApps on Ethereum across sectors such as gaming, finance, healthcare, and supply chain.
3. Ethereum 2.0 and Proof-of-Stake (PoS):
Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake in a major upgrade known as "The Merge" in 2022. This reduced energy consumption by over 99%, significantly improving Ethereum’s environmental impact.
4. Scalability Solutions:
Ethereum is undergoing further upgrades, including sharding and Layer 2 solutions (e.g., Optimism, Arbitrum), to enhance speed and reduce transaction costs.

Use Cases of Ethereum
DeFi (Decentralized Finance):
Ethereum hosts the majority of DeFi protocols like Uniswap, Aave, and MakerDAO, enabling users to lend, borrow, and trade without centralized banks.
NFTs (Non-Fungible Tokens):
Ethereum is the leading blockchain for NFTs, powering platforms like OpenSea and artists around the world to tokenize digital art.
Enterprise Adoption:
Major companies and governments are exploring Ethereum for supply chain, identity management, and cross-border payments.

Risks and Considerations
Network Congestion & Gas Fees:
High demand can lead to increased transaction costs, although ongoing scalability upgrades aim to address this issue.
Regulatory Uncertainty:
Global regulatory stances on Ethereum and DeFi continue to evolve, which may impact usage and investment.
Competition:
Other smart contract platforms like Solana, Cardano, and Avalanche are competing for market share and developer attention.

ETH as an Investment
ETH is not just a currency—it represents a stake in the Ethereum ecosystem. Many investors view it as a long-term play on the future of decentralized technology. With staking now live, holders can also earn passive income by validating transactions.
