QTUM, pronounced as quantum, combines the reliability of Bitcoin's blockchain with the possibilities that smart contracts offer. It has been designed for stability, modularity and interoperability. QTUM is the first toolkit for building familiar, decentralized applications, suitable for real-world, business-oriented use cases. After a first crowd sale in March, the mainnet of QTUM went live in September 2017. The project was founded and is led by Patrick Dai. In addition to QTUM, Patrick is also responsible as CTO at Bitse Group. One of China's largest mining companies.
