Sure! Here's a hundred-word speech on Ethereum (ETH):

---

Ethereum, commonly known as ETH, is a revolutionary cryptocurrency and decentralized platform that transformed the digital world. Created by Vitalik Buterin in 2015, Ethereum introduced the concept of smart contracts — self-executing agreements without intermediaries. It powers a global network of decentralized applications (dApps) across finance, art, gaming, and beyond. Ethereum’s blockchain is highly secure, transparent, and versatile, making it a foundation for innovations like NFTs and decentralized finance (DeFi). With its recent upgrades, Ethereum is becoming more energy-efficient and scalable. ETH is not just digital money; it represents a new internet of value and trustless collaboration worldwide.
