Qtum Blockchain (short for "quantum chain" or "Qtum"), as an open source Blockchain project, is the first value transfer network and smart contract platform based on UTXO model, adopting PoS consensus mechanism and decentralized governance mechanism, and compatible with multiple virtual machines. Through the new design of abstraction layer (AAL) connect the COINS and etheric fang ecological, hierarchical design for quantum chain block chain has brought more flexibility, the same block chain is compatible with a variety of virtual machine or smart contract running environment, existing applications can be real-time interaction on mobile devices, continue to expand more commercial block chain, Qtum broaden the ecological intelligence contracts, The pioneering x86 virtual machine will make the next generation of decentralized applications a reality -- developers will be able to develop smart contracts in a variety of major programming languages. In 2017, the global network of Qtum, the backbone of quantum chain, was officially launched, with nodes in more than 24 countries around the world, second only to Ethereum and Bitcoin in peak period.

Qtum quantum chain has also signed memorandums of cooperation with 360, a Chinese Internet security expert, and Baofeng, a video network portal giant, to carry out in-depth cooperation in the deployment of all nodes in the blockchain network, blockchain network security, blockchain and video industry integration, and blockchain open source community construction. Join hands to promote the commercial implementation and technological development of China's blockchain technology. Qtum has established blockchain technology incubators in university of California, Berkeley, Tallinn University of Science and Technology, Columbia University, Xi 'an Jiaotong University and other famous universities at home and abroad to deeply study and explore the real application scenarios combining smart devices and distributed ledger technology.
