Ethereum (ETH)

What is Ethereum?

Ethereum is a decentralized layer-1 blockchain platform designed specifically to support smart contracts and decentralized applications. The network officially launched in 2015, with its creation attributed to founders Vitalik Buterin, Gavin Wood, and Joseph Lubin. To secure the network and process transactions, Ethereum utilizes a proof-of-stake consensus mechanism. The primary use case for the native ETH token involves paying for transaction fees and computational services when interacting with smart contracts on the platform. Today, Ethereum operates as a major smart-contract platform within the broader cryptocurrency ecosystem, maintaining its position as the number two ranked digital asset by market capitalization.

How does Ethereum work?

Ethereum operates on a proof-of-stake consensus mechanism, which is a system used to validate transactions and secure the network. Instead of using mining equipment, this method relies on participants locking up their tokens as collateral. This staking process ensures that those securing the blockchain have a financial interest in maintaining honest operations.

The network relies on participants known as validators, who run specialized software to propose and verify new blocks. These validators replace traditional miners and are randomly selected by the protocol to confirm pending transactions. By distributing this validation work across many independent nodes, the system prevents any single entity from controlling the network.

When a user initiates a transfer or interacts with a smart contract, the transaction is broadcast to active validators. These validators check the digital signatures and available balances before grouping the valid requests into a new block. Once a block is finalized and added to the chain, the transaction is permanently settled.

Ethereum use cases

Ethereum tokenomics

The tokenomics of Ethereum are defined by its circulating supply and its specific issuance model. Currently, the network has a circulating supply of 120683010.807681 ETH tokens. Unlike some digital assets, Ethereum does not have a hard-capped maximum supply, meaning that new tokens can continue to be created over time. This issuance is directly tied to the proof-of-stake consensus mechanism, where new ETH is generated to reward validators who actively secure the network and process transactions. Because there is no predefined maximum limit, the total supply fluctuates based on the balance between the ongoing creation of new validator rewards and the network mechanisms that remove tokens from circulation. This dynamic supply model ensures that validators are continuously incentivized to maintain the integrity of the layer-1 blockchain.

Ethereum price history & milestones

Ethereum officially launched in 2015, introducing a new layer-1 smart-contract platform to the digital asset market. During its earliest days of trading, the token experienced its all-time low price of $0.4209 on October 21, 2015. Over the subsequent years of development and network adoption, the asset saw significant market activity. This activity eventually culminated when Ethereum reached its all-time high price of $4953.73 on August 24, 2025. Since that peak, the token has continued to trade actively across global cryptocurrency exchanges as the ecosystem matures. Today, Ethereum maintains a highly prominent position within the broader digital economy, currently holding the rank of number 2 among all cryptocurrencies by market capitalization.
