Ether is a cryptocurrency that powers the Ethereum network, which is a decentralized platform that enables the creation of decentralized applications (dapps) and smart contracts. Ether differs from Bitcoin in several ways. Firstly, Bitcoin's primary purpose is to serve as a store of value and a means of exchange, whereas Ether is used primarily to fuel the Ethereum network and execute smart contracts. Secondly, Bitcoin uses a proof-of-work consensus mechanism to validate transactions and create new blocks, while Ethereum is in the process of transitioning to a proof-of-stake consensus mechanism. Additionally, Ethereum has a more flexible scripting language, allowing for more complex smart contracts to be executed on the network. Finally, Ethereum has a larger and more active developer community, leading to a wider range of dapps and use cases being developed on the platform. Overall, while both Bitcoin and Ether are cryptocurrencies, they have different purposes and use cases within the broader cryptocurrency and blockchain ecosystem.

Ether (ETH) is the native cryptocurrency of the Ethereum blockchain, which supports decentralized applications (dApps) and smart contracts. Unlike Bitcoin, which primarily serves as a digital currency and store of value, Ethereum aims to provide a platform for developers to build and run these dApps.

Ether is used to facilitate transactions and computational services on the Ethereum network. Its value is partly derived from the demand for these services.

The key differences between Ether and Bitcoin include their purposes and functionalities. Bitcoin focuses on being a decentralized digital currency, while Ethereum offers a versatile platform for decentralized computing. Additionally, Ethereum's network supports more complex transactions and applications through its Turing-complete programming language, making it distinct from Bitcoin's more straightforward transactional focus.
