$ETH Ethereum (ETH) is a decentralized, open-source blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum has become one of the leading cryptocurrencies and blockchain technologies.

Here are some key features of Ethereum:

1. Smart Contracts: Ethereum allows developers to create self-executing contracts where the terms of the agreement are directly written into code. This enables trustless transactions and automation of processes.

2. Decentralized Applications (dApps): On the Ethereum blockchain, developers can build applications that run on a decentralized network, making them resistant to censorship and downtime.

3. Ethereum Virtual Machine (EVM): The EVM is the runtime environment for executing smart contracts on Ethereum. It allows for the execution of code in a secure and isolated environment.

4. Ethereum 2.0: Ethereum is transitioning from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) mechanism with Ethereum 2.0. This upgrade aims to improve scalability, security, and energy efficiency.

5. Tokens: Ethereum supports the creation of tokens using standards like ERC-20 (for fungible tokens) and ERC-721 (for non-fungible tokens). This has led to the proliferation of various cryptocurrencies and digital assets on its platform.

6. DeFi and NFTs: Ethereum is the backbone of the decentralized finance (DeFi) revolution and the non-fungible token (NFT) market, allowing for innovative financial products and unique digital assets.
