Ethereum (ETH)

What is Ethereum?

Ethereum is a decentralized blockchain platform designed to support smart contracts and decentralized applications (dApps). It was launched in 2015 by a team of founders, including Vitalik Buterin, Gavin Wood, and Joseph Lubin. The network operates using a proof-of-stake consensus mechanism, where validators secure the network by staking the native token, ETH. This model is responsible for validating transactions and adding new blocks to the chain. Its primary function is to serve as a global, open-source platform for applications that operate without a central authority. As a foundational layer-1 blockchain, it provides the infrastructure for a wide array of projects in decentralized finance and other sectors.

How does Ethereum work?

Ethereum operates on a proof-of-stake consensus mechanism to maintain its network integrity and security. In this system, participants known as validators are selected to create new blocks and confirm transactions. Validators must lock up a quantity of ETH as collateral, which incentivizes them to act honestly in the network's interest.

The network is maintained by a distributed system of nodes operated by these validators around the world. These participants run specialized software to verify transactions and ensure the blockchain state remains consistent across all nodes. Their role is critical for processing data and upholding the decentralized nature of the platform without a central coordinator.

When a user initiates a transaction, it is broadcast to the network and placed in a pool of pending transactions. A selected validator then gathers a set of transactions from this pool to form a new block. After the block is proposed and attested to by other validators, it is finalized and added to the chain.

Ethereum use cases

Ethereum tokenomics

The tokenomics of Ethereum (ETH) are defined by its supply mechanics and issuance model. Unlike some cryptocurrencies, Ethereum does not have a fixed maximum supply, meaning there is no hard cap on the total number of ETH that can be created. The current circulating supply is 120683100.569256 ETH. New ETH is issued as rewards to validators for securing the network under its proof-of-stake consensus mechanism. A portion of transaction fees is also burned, or permanently removed from circulation, which introduces a deflationary element to the supply dynamics. This balance between issuance and burning affects the total supply over time, making it variable.

Ethereum price history & milestones

Ethereum was launched in 2015 and has since become a significant asset in the digital currency market. Its price history includes notable fluctuations, reflecting various stages of its development and adoption. According to historical data, the all-time low for ETH was recorded on 2015-10-21, when its price was $0.4209. The token reached its all-time high price of $4953.73 on 2025-08-24. These two points represent the extremes of its valuation over its history. Based on market capitalization, Ethereum holds the rank of 2 among cryptocurrencies, indicating its position within the broader digital asset ecosystem. Market conditions can influence its value.
