$ETH is the second largest blockchain platform in the world, founded by Vitalik Buterin and others in 2015. Its core function is to support smart contracts and decentralized applications (DApps). Its native token ETH is not only the transaction fuel (Gas fee) but also the core asset of ecosystems such as DeFi and NFTs.

Ethereum is known for its technological innovation: in 2022, it completed 'The Merge', transitioning from the energy-intensive PoW mechanism to the environmentally friendly PoS consensus, and plans to enhance performance through sharding technology and Layer 2 scaling solutions (such as Rollups). Its smart contracts support automated execution of protocols, giving rise to innovative fields such as decentralized finance (DeFi), blockchain gaming, and DAOs.

As the infrastructure of Web3, the Ethereum ecosystem covers thousands of DApps, with a long-term total locked value (TVL) consistently at the top. Despite challenges such as high Gas fees and competition from other public chains (such as Solana), its security, developer community, and continuous upgrades (like the Pectra upgrade in 2025) still reinforce its industry-leading position, making it a benchmark in the evolution of blockchain technology.
