What is ETH: The Digital Fuel Powering the Ethereum Network

Ethereum's Positioning and Significance

In 2015, Vitalik Buterin and his team launched Ethereum (ETH), aiming to solve issues such as limited blockchain functionality and the need for programmable money. As the first smart contract platform, Ethereum plays a crucial role in DeFi, NFTs, and decentralized applications (DApps).

As of 2025, Ethereum has become the second-largest cryptocurrency by market capitalization, boasting millions of users and a vibrant developer community. This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Ethereum was created by Vitalik Buterin and co-founders in 2015, aiming to extend blockchain technology beyond simple value transfer. It emerged during the blockchain technology boom, with the goal of providing a platform for decentralized applications and smart contracts. Ethereum's launch brought new possibilities for developers and businesses looking to leverage blockchain technology.

Important Milestones

• 2015: Mainnet launch, introducing smart contract functionality.
• 2022: The Merge upgrade transitioned Ethereum from Proof-of-Work to Proof-of-Stake.
• 2023: Shanghai upgrade enabled staking withdrawals, boosting network participation.
• 2025: Ecosystem explosion, with DeFi protocols and NFT platforms numbering in the thousands.

With support from the Ethereum Foundation and a global community, Ethereum continues to optimize its technology, security, and real-world applications.

How Does Ethereum Work?

No Central Control

Ethereum runs on a decentralized network of computers (nodes) worldwide, free from bank or government control. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, empowering users with greater autonomy and enhancing network resilience.

Blockchain Core

Ethereum's blockchain is a public, immutable digital ledger recording every transaction. Transactions are grouped into blocks, linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Layer 2 solutions and upcoming sharding technology further enhance performance.

Ensuring Fairness

Ethereum uses Proof-of-Stake (PoS) to validate transactions and prevent fraudulent activities like double-spending. Validators stake ETH to maintain network security and receive rewards. This innovative approach is more energy-efficient and offers higher throughput compared to the previous Proof-of-Work system.

Secure Transactions

Ethereum uses public-private key cryptography to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, with transactions remaining pseudonymous. Additional security features include smart contract audits and formal verification techniques.

Ethereum's Market Performance

Circulation Overview

As of November 14, 2025, Ethereum's circulating supply is 120,696,353.1837874 coins, which is equal to its total supply. The maximum supply is listed as ∞, indicating an inflationary model.

Price Fluctuations

Ethereum reached its all-time high of $4,946.05 on August 25, 2025, driven by market bullish trends and increased institutional adoption.

Its lowest price was $0.432979, recorded on October 20, 2015, likely due to the early stages of the project and market uncertainty.

These fluctuations reflect market sentiment, adoption trends, and external factors influencing the cryptocurrency space.
