Ethereum (ETH)

What is Ethereum?

Ethereum is a decentralized layer-1 blockchain platform designed specifically for executing smart contracts and building decentralized applications. The Ethereum mainnet officially launched in the year 2015, having been founded by a team that includes Vitalik Buterin, Gavin Wood, and Joseph Lubin. The network operates using a proof-of-stake consensus mechanism to secure its infrastructure and process network activity. Its primary use case involves providing a foundational layer where developers can deploy decentralized finance protocols and issue new digital tokens. Today, the Ethereum platform maintains its position as a major smart-contract platform within the broader cryptocurrency ecosystem, holding the rank of number two by market capitalization.

How does Ethereum work?

Ethereum operates on a proof-of-stake consensus mechanism to validate transactions and secure the underlying blockchain network. This system requires participants to lock up their native tokens as collateral rather than expending computational energy. The proof-of-stake model ensures that the decentralized ledger remains accurate and resistant to external manipulation.

The network relies on active participants known as validators to propose and verify new blocks of data. These validators run specialized node software that constantly communicates with other nodes across the global network. If a validator acts maliciously or fails to stay online, they can lose a portion of their staked collateral.

When a user initiates a transaction, it is broadcast to the network and placed into a temporary waiting area. Validators then select these pending transactions, execute the associated smart contract logic, and bundle them into a new block. Once the block is finalized by the broader network, the transaction becomes a permanent part of the blockchain history.

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 approximately 122050160.835643 ETH tokens. Unlike some other cryptocurrencies, Ethereum does not have a hard-capped maximum supply, meaning that new tokens can continue to be created over time. The issuance of these new tokens is directly tied to the proof-of-stake consensus mechanism, where validators receive rewards for securing the network and processing transactions. Because there is no maximum supply limit, the network relies on various internal mechanisms to manage the overall inflation rate of the circulating supply. This ongoing issuance ensures that validators remain incentivized to participate in the long-term operation of the decentralized smart-contract platform.

Ethereum price history & milestones

The Ethereum network officially launched in the year 2015, introducing a new foundational layer for decentralized applications to the digital asset market. During its earliest recorded trading period, the asset experienced its all-time low price of $0.4209 on 2015-10-21. As the ecosystem expanded over the following years, the valuation of the native token increased significantly alongside broader market adoption. Eventually, the cryptocurrency reached its all-time high price of $4953.73 on 2025-08-24. Today, Ethereum maintains a highly prominent position within the global cryptocurrency landscape, currently holding the rank of number 2 by total market capitalization. This historical trajectory reflects its ongoing role as a primary smart-contract platform in the digital economy.
