Ethereum Tag – All About Ethereum, Smart Contracts, DeFi & More

When working with Ethereum, a decentralized, open‑source blockchain that runs self‑executing code and uses the native ETH token. Also known as ETH, it fuels a massive ecosystem of decentralized applications.

Key to Ethereum’s power are Smart contracts, self‑executing programs that run exactly as written without a middleman. These contracts enable the creation of ERC‑20 tokens, a standard for fungible assets that lets developers launch new coins on the same network. Together they give rise to DeFi, decentralized finance platforms that replace banks with code, offering lending, trading, and yield farming. While Ethereum provides the base layer, developers often rely on Layer 2 solutions—rollups, sidechains, and state channels—to cut gas fees and boost transaction speed.

Why Ethereum Matters Today

Ethereum’s shift from Proof‑of‑Work to Proof‑of‑Stake in 2022 reduced energy use by over 99%, making the network greener and more appealing to institutions. The Ethereum Virtual Machine (EVM) runs every smart contract, meaning any developer familiar with EVM can deploy on multiple chains that support it. Gas fees, the cost to execute contracts, still affect user experience, which is why Layer 2 scaling is a hot research area. Projects like Optimism and Arbitrum bundle many transactions off‑chain and settle them on Ethereum, preserving security while delivering near‑instant confirmations.

All of this creates a vibrant landscape: you’ll see guides on tokenomics, reviews of exchanges that list ERC‑20 assets, deep dives into sharding, and even tutorials on building your own smart contract. Below, we’ve gathered the most relevant articles—from how to stake ETH to the latest in DeFi yield strategies—so you can jump straight into the parts that match your interest.

In short, Ethereum continues to reshape finance, gaming, and identity on the web. Explore the posts below to see how the concepts we just covered work in real‑world projects.
