QTUM

QTUM is a blockchain platform that combines the features of Bitcoin and Ethereum. It aims to provide the security of Bitcoin's UTXO (unspent transaction outputs) model while also incorporating smart contract functionality similar to that of Ethereum. QTUM is designed to facilitate the development and deployment of decentralized applications (dApps) and to enable the use of smart contracts across various platforms while maintaining interoperability. The platform utilizes a proof-of-stake consensus mechanism, promoting energy efficiency and scalability. QTUM is also notable for its ability to connect to existing blockchain networks and interact with external applications, making it versatile for various use cases in the blockchain ecosystem.
