## TL;DR

Ethereum is a blockchain platform for decentralized applications and smart contracts. This repair removes live market claims and keeps to Ethereum documentation and the whitepaper.

## Core Explanation

The article now focuses on stable concepts: Ethereum as a programmable blockchain, smart contracts as programs deployed to the network, and proof of stake as the current consensus mechanism described by Ethereum documentation.
