“Ethereum is the second-biggest cryptocurrency in the world after Bitcoin. It’s also very different from Bitcoin in its structure and purpose. Ethereum wasn’t developed as a currency alone. Its innovation lies in opening the blockchain up to development for different applications outside currencies and finance. Developers can build software on top of Ethereum’s blockchain, and use the network’s distributed ledger to build trust for all kinds of applications. Since the Ethereum blockchain is decentralized, once a developer has built an application, it can’t be censored or taken down by any authority. That application lives as long as the Ethereum blockchain continues.”
