Qtum

An open source, decentralized project that aims to capitalize on the success of Bitcoin, while competing for the Decentralized Application (Dapp) and Smart Contract market

- Compatible with Bitcoin and Ethereum ecosystems: * Solidity and EVM are used for developing blockchain applications, existing Ethereum applications can be ported to Quantum’s Blockchain) * Directly integrating the existing Ethereum Virtual Machine (EVM) into Bitcoin’s UTXO model, allowing for Ethereum-based smart contracts to be executed on a Bitcoin-based Unspent Transaction Output (UTXO) blockchain - Value Transfer Protocol can be used to support and enhance various industries such as the financial sector, supply chain tracking, internet of things, and social media - "Go Mobile" strategy: the core developers of Qtum will work to ensure that third party developers have ample infrastructure and functionality to support mobile use cases (a mobile wallet, API, and a framework for creating decentralized mobile applications) - A modular design approach can help developers better maintain the system.

Qtum has been created by forking Bitcoin’s source code and adding various custom modules to integrate the EVM. Qtum proposes a series of innovations in blockchain technology and implementation: - a UTXO model based smart contract platform - a flexible consensus (Proof-of-Stake) mechanism for public and permissioned chains - the Master Contract concept, identity management through smart contracts. Qtum is secured by the Proof-of-Stake 3.0 (POS 3.0) consensus protocol.
