DescriptionQtum provides a Turing-complete blockchain stack, able to execute smart contracts and decentralized applications, comparable to the Ethereum blockchain. However, in contrast to Ethereum, Qtum is built upon Bitcoin's well established UTXO transaction model and employs a proof-of-stake consensus mechanism that is more practical for business adoption.
