Qtum

Key Technical Advantages:

Account Abstraction Layer (AAL): Qtum has developed an Account Abstraction Layer (AAL) that integrates the Unspent Transaction Output (UTXO) model and the smart contract Account model ecosystem. This effectively resolves the issue of insufficient compatibility between different blockchains. The AAL also provides the ability to use multiple virtual machines without modifying the underlying architecture. Qtum x86 Virtual Machine: The Qtum x86 virtual machine is a new development that enhances the programming capabilities of the blockchain. It separates the operating system from the virtual machine, which brings smart contract development to the mainstream. The x86 virtual machine uses Von Neumann computer architecture, supporting many existing compilers and programming languages, thus making it easier for developers to write smart contracts. Proof-of-Stake (PoS) Consensus Mechanism: Qtum introduced an innovative PoS consensus mechanism. PoS nodes are distributed worldwide, enabling efficient collaboration of global PoS peer-to-peer networks. The improved PoS mechanism, called Mutualized Proof-of-Stake (MPoS), mitigates security risks by sharing block rewards among block-producing nodes and delaying payments, making attacks more costly and less predictable. Decentralized Governance Protocol (DGP): Qtum has developed the first DGP system for on-chain governance to maintain the stable operation of the entire system. It allows for on-chain negotiation and execution of blockchain network update protocols. The DGP allows multiple participants, including QTUM token holders, developers, community member representatives, miners, and others to propose and vote on governance proposals. Qtum Chain Foundation: The Qtum Chain Foundation is a non-profit organization registered in Singapore that oversees the overall strategic planning of the Foundation. The structure of the Qtum Chain Foundation includes positions such as COO, CIO, CTO, and Lead Developer, ensuring the smooth operation of the Foundation. The Foundation also promotes transparency in governance to facilitate the safe and harmonious development of the project. Content summarized by AI chatbot
