$ETH

Eth is a common abbreviation for Ethereum, a decentralized blockchain platform that enables the creation of smart contracts and distributed applications (dApps). It was proposed in 2013 by Vitalik Buterin and launched in 2015. Ethereum uses its own cryptocurrency, called Ether (ETH), which is used to pay for transactions within the network.

Unlike Bitcoin, which focuses on being a digital currency, Ethereum is more flexible and allows the execution of programs on its blockchain. This has enabled the development of sectors such as decentralized finance (DeFi) and non-fungible tokens (NFTs). In 2022, Ethereum underwent a transition to a proof-of-stake system called "The Merge," significantly reducing the network's energy consumption.

Today, Ethereum continues to evolve with improvements in scalability and security. It is one of the key technologies in the development of decentralized applications and has influenced the way we interact with digital financial systems.
