Learn why Ethereum added programmable applications and how ETH differs from a token on Ethereum.

A programmable shared computer
Ethereum’s early whitepaper described a general-purpose platform for applications using a blockchain. Its mainnet launched in 2015. Developers can deploy smart contracts: programs whose execution is checked by the network. ETH is the native asset used for transaction fees and staking.
A token created by a smart contract is not the same asset as ETH. An application’s failure also does not necessarily mean that Ethereum itself failed.
Major changes to the network
The Merge on September 15, 2022 replaced Ethereum’s proof-of-work consensus with proof of stake. Shapella in April 2023 enabled staking withdrawals. Dencun in March 2024 introduced blobs, a data mechanism intended to support rollups.
The published technical roadmap records Pectra in May 2025 and Fusaka in December 2025. As checked on September 8, 2026, later roadmap items remain plans rather than completed upgrades. Dates and scope can change; use the linked roadmap for the latest status.
Understanding the present ecosystem
Ethereum includes a base network, rollups, wallets, applications and infrastructure providers. A transaction on a rollup can have different costs, withdrawal steps and operational assumptions from one on the base network.
Read a network update by asking three questions: what changed, who must update software and which users are affected? Keep those engineering questions separate from predictions about ETH’s price. Our Ethereum news category tracks reported developments; this guide supplies the background.
