Ethereum 

The project derived from playing a game and not being able to have ownership of the sword that Vitalik described and the quest that later led to the development of Ethereum, one of the great inventions of the 21st century. The idea of ownership, smart contracts, and helping companies or startups develop decentralized apps gave a new wave of breakthroughs. Reading their blog, history, and use cases simply inspires evolution. Ethereum is being utilized for a wide range of use cases, including DeFi (Decentralized Finance), NFTs (Non-Fungible Tokens), supply chain management, voting systems, identity verification, and imagination seems to be the limit. Even though there are many more chains that are offering cheaper gas fees, and more robust infrastructure, Ethereum remains and will always be remembered for taking the lead in making a difference.
