$ETH

Ethereum is a decentralized and open-source blockchain platform that enables the creation of smart contracts and decentralized applications (dApps). It was proposed by Vitalik Buterin in 2013 and launched on July 30, 2015.

Key Features:

1. Smart Contracts: These are programs that automatically execute when certain conditions are met, without the need for intermediaries.

2. Decentralized Applications (dApps): Applications that operate on the blockchain, eliminating the need for centralized servers.

3. Ether (ETH): The native cryptocurrency of Ethereum, used to pay transaction fees and computational services on the network.

4. Proof of Stake (PoS): Ethereum transitioned from Proof of Work (PoW) to PoS in "The Merge," becoming more energy efficient.

5. Decentralized Finance (DeFi): Ethereum is the foundation of DeFi, enabling financial services without traditional banks.

6. Non-Fungible Tokens (NFTs): Ethereum is the leading platform for creating and trading NFTs, representing ownership of unique digital assets.
