Qtum (read Quantum) is a Chinese hybrid platform that connects the existing blockchain with a virtual machine, such as Ethereum. In the Qtum blockchain, there is an internal token – Qtum coin. It is a platform that enables developers to build applications and smart contracts on the current blockchain technology.

Focusing on building a platform that helps companies create smart contracts on blockchain, Qtum is a toolkit in the first place. Designed to be both robust and modular, the platform can create small contracts to be used on most major blockchain.
