The project Qtum is an interesting decentralized app (Dapp) venture that combines the Bitcoin client 0.13, Proof of Stake (PoS), and the Ethereum Virtual Machine to enable smart contract services. The project has also received $1 million in funding from investors such as Fenbushi partner Bo Shen, Ethereum co-founder Anthony Di Iorio, BitFund founder Xiaolai Li, and more. Qtums goal is to provide a value transfer protocol Dapp platform with the best properties of both projects.
Qtum integrated the EVM onto a UTXO-based blockchain, and writing contracts for this should be just as easy as for Ethereum, but you get the benefits of the UTXO model, explains Qtum developer Jordan Earlz. These benefits include mobile/light wallet support by SPV, a more stable model (whereas Ethereum has forked many times to fix problems with this), and compatibility with existing Bitcoin tools and protocols
