What is Ethereum (ETH)?

Deep Dive

1. Purpose & Value Proposition

Ethereum was designed as a “world computer” to enable decentralized applications resistant to censorship or third-party control (CoinMarketCap). Its core innovation, smart contracts, allows developers to build applications for finance (DeFi), digital ownership (NFTs), and governance (DAOs). Over 55% of tokenized real-world assets (RWAs) like bonds and stocks are hosted on Ethereum, driven by its standardized ERC-20 and ERC-721 token frameworks (Cube Exchange).

2. Technology & Architecture

Ethereum operates on a proof-of-stake consensus mechanism since 2022’s Merge upgrade, reducing energy use by 99.95%. Its Ethereum Virtual Machine (EVM) executes code across thousands of nodes, ensuring decentralization. Scaling relies on Layer-2 rollups (e.g., Arbitrum, Optimism), which batch transactions off-chain while inheriting Ethereum’s security. Upgrades like Dencun (2024) introduced “proto-danksharding” to lower rollup costs by 90%, addressing scalability bottlenecks (CCN).

3. Tokenomics & Governance

ETH serves three primary roles:
- Gas fees: Paid to execute transactions or smart contracts.
- Staking: Validators lock 32 ETH to secure the network, earning ~3-5% annual rewards.
- Scarcity: EIP-1559 (2021) burns a portion of transaction fees, making ETH deflationary during high activity.
Decisions are community-driven via Ethereum Improvement Proposals (EIPs), with core developers and stakeholders collaborating on upgrades (Ethereum Foundation).

Conclusion

Ethereum is the foundational infrastructure for decentralized applications, combining programmable money, open governance, and institutional-grade security. As it evolves toward greater scalability and real-world utility, one question remains: Can Ethereum maintain its dominance as competing blockchains target niche use cases?
