What is ETH?
Ethereum is a decentralized blockchain platform that allows for smart contracts and decentralized applications (dApps). It serves as the foundation for the next generation of the internet, often called Web3.
- Programmable blockchain – Runs self-executing agreements (smart contracts) without needing middlemen.
- Proof-of-Stake system – Secured by validators who stake ETH, cutting energy use by 99.95% after the upgrade known as The Merge.
- Ecosystem backbone – Supports decentralized finance (DeFi), NFTs, DAOs, and institutional tokenization through ERC standards.
Deep Dive
1. Purpose & Value
Ethereum was created to support trustless and censorship-resistant applications using smart contracts—computer programs that automatically carry out agreements like loans or trades when certain conditions are met. Unlike Bitcoin, which mainly focuses on digital payments, Ethereum acts as a global platform for programmable value, powering everything from decentralized exchanges to tokenized assets (Cube Exchange).
2. Technology & Structure
In 2022, Ethereum switched to a proof-of-stake (PoS) system through an upgrade called “The Merge.” This replaced energy-heavy mining with validators who lock up ETH to help secure the network. Other improvements, like EIP-1559 (which burns transaction fees) and the upcoming Dencun upgrade (introducing proto-danksharding in 2024), have made the network more scalable and lowered transaction costs on layer-2 solutions by about 90% (CCN).
3. Ecosystem Basics
Ethereum’s ERC standards (ERC-20 for tokens and ERC-721 for NFTs) support a $160 billion+ ecosystem. It hosts over half of tokenized real-world assets, including funds like BlackRock’s BUIDL, and handles roughly 60% of stablecoin transactions. Layer-2 networks such as Arbitrum and Base process 75% of daily activity, making transactions faster and cheaper (CryptoPotato).
Conclusion
Ethereum has transformed blockchain technology by combining decentralized trust with programmable features. It now serves as the infrastructure for global finance and digital ownership. As more institutions use its tokenization tools, the question remains: can Ethereum keep its edge against other solutions aiming to improve scalability?
