Here is a brief and useful overview of Ethereum (ETH):
---
Ethereum (ETH) is the second largest cryptocurrency by market capitalization after Bitcoin. It was launched in 2015 by Vitalik Buterin, and it is not just a currency, but a platform that allows for the creation of smart contracts and decentralized applications (dApps). Its network uses blockchain technology, but unlike Bitcoin, Ethereum focuses on programmability and development.
In 2022, it transitioned from a proof-of-work (PoW) system to proof-of-stake (PoS) through the The Merge update, making it more energy-efficient.
ETH is the token used for payments within the network, whether for transactions or executing contracts.
