The majority of prior-generation blockchain frameworks have serious limitations:
Scalability issues;
Systems heavily reliant on servers;
Limited functionality, and etc.
The well-known and prominent smart contract-powered Ethereum continues to face major obstacles in scalability, security and network congestion.
Our challenge for this particular project was to build the first UTXO-based smart contract platform with a proof-of-stake (PoS) consensus model: a scalable blockchain framework for DApp development that would allow building smart contracts using Solidity, C, C++ and other languages widely used in the blockchain environment.
The goals were to bring smart contracts to everyone, including clients in low-bandwidth environments, as well as offer such major benefits as:
A standard coding library;
An optimized gas charging model;
New possibilities for creation, execution, and management of modern smart contract applications;
Multiple APIs for easy plug and play;
Support for alternative data storage.
Qtum is an open-source hybrid blockchain application platform. Qtum’s core technology combines the security of UTXO model, robust Bitcoin core architecture and an Account Abstraction Layer, which acts as a bridge to communicate multiple Virtual Machines, including the Ethereum Virtual Machine (EVM) and x86 VM. The Proof-of-Stake consensus mechanism enables true decentralization, while also increasing stability, security and efficiency of the blockchain platform.
Decentralized Governance Protocol (DGP)
Enterprise Blockchain Development
Unita, the latest development and contribution to Qtum framework, is an enterprise edition of Qtum that allows to rapidly deploy blockchain technology. It features high tps and short confirmation time for blocks, providing businesses with an advanced tool that opens the door for new opportunities.
