Qtum (quantum), a hybrid of Bitcoin and Ethereum set up by the Qtum Foundation in Singapore, is an open source blockchain. It is called a hybrid blockchain, because it uses Bitcoin’s security and stability with Ethereum’s efficiency and functionalities (smart contracts and dApps). With the bridge between Bitcoin and Ethereum, like Ethereum, they want to be the solution to offer smart contracts for companies and dApps for developers on a trusted basis. In March 2017, PwC (PriceWaterhouseCoopers), the large multinational, showed great potential in the crypto as an interesting blockchain for their business operations with a platform for smart contracts.
