Bitcoin was a pioneer in the blockchain revolution by establishing a public, permissionless, distributed ledger system to validate, store, and replicate transaction data on computers all over the world. Ethereum expands these concepts by harnessing that same blockchain capability for computer code. While Bitcoin offers one particular application of blockchain technology, a peer-to-peer electronic cash system, Ethereum allows for scripts of code to be run as a global computational network. This concept has a wide range of potential applications such as voting, global supply chains, medical records, the financial system — the opportunities are endless.
Ethereum is a distributed public blockchain network that focuses on running the programming code of any decentralized application. More simply, it is a platform for sharing information across the globe that cannot be manipulated or changed.
Ethereum is useful and valuable because of its ability to have a wide variety of intelligent applications built on top of it, including anything from financial contracts to voting and governance applications. Today, the authentication for these processes can take days or even weeks. With Ethereum, verification is almost instant. As the platform grows, it could continue to change the way we do business and transact on a daily basis.
