Ethereum marks its 10th anniversary, celebrating its evolution from a whitepaper by Vitalik Buterin to a $75 billion decentralized economy. Since its launch on July 30, 2015, Ethereum has introduced smart contracts, significantly impacting blockchain technology. Despite challenges like the 2016 DAO hack, Ethereum has supported ICOs, DeFi, and transitioned to proof-of-stake in 2022. Recent upgrades, including Shapella and Dencun, have improved scalability and data handling. As Ethereum continues to innovate, it aims to become the settlement layer for tokenized assets, shaping the future of decentralized finance.
