Combining a modified Bitcoin Core infrastructure with an intercompatible version of the Ethereum Virtual Machine (EVM), Qtum merges the reliability of Bitcoin’s unfailing blockchain with the endless possibilities provided by smart contracts. Qtum makes it easier than ever for established sectors and legacy institutions to interface with blockchain technology.
Qtum extends Bitcoins 'Script' language so that it functions as a vehicle to transport code to Qtum’s version of the EVM. With this, it is now possible to execute smart contracts and run decentralized applications. Building on Bitcoin’s UTXO model, the simple payment verification (SPV) protocol is supported by the Qtum codebase by default. As a result, it is now possible to execute smart contracts from lite wallets, which can be easily installed on any given mobile device.
