Why Build on Ethereum

Ethereum was built by developers for developers to be the most accessible, flexible, and resilient blockchain in the world. As of last year, the Ethereum ecosystem has 4x more devs than any other blockchain community. Every day, Ethereum devs build on the tools that others have built to launch privacy solutions, DeFi protocols, gaming apps, and more. We call this cooperation of parts composability. It is the Ethereum developer community’s superpower, and what makes the network so trustworthy, and unstoppable. 

At the heart of Ethereum’s design is the principle of decentralization, which is about pushing decisions to the edges and empowering anyone and everyone to support the network. During these unprecedented times, in which our social, economic, and technological infrastructure faces immense levels of uncertainty due to the coronavirus pandemic, many are discovering the power of decentralizationhow grassroots efforts to crowdsource supplies, computing power, information, and even goodwill can help centralized institutions keep pace with the crisis. Building on Ethereum is about tapping into that power at the digital layer and discovering that you as an individual can play a part in the future of our global infrastructure. Thousands of builders are already at work, and they need your help.
