Quantum Fusion Network (QFN) is a Layer 1 blockchain platform designed for decentralized applications (dApps), focusing on speed and usability. It aims to address the limitations of existing blockchains to facilitate mainstream adoption of dApps.

Overview

Quantum Fusion Network (QFN) is designed to overcome barriers hindering the widespread use of decentralized applications. The network seeks to provide faster transaction speeds and a more user-friendly development environment compared to existing blockchain platforms ^[1]. QFN is built using the Substrate framework and incorporates several modifications to improve performance and scalability ^[1]. The network aims to achieve 0.1-second block times and high transaction throughput by using a combination of consensus mechanisms and parallel processing techniques ^[1].

QFN aims to provide developers with tools to create responsive, real-time dApps. The network incorporates features such as a native-first Software Development Kit (SDK), PolkaVM for smart contract execution, and verifiable off-chain workers for complex computations ^[1]. By combining these technologies, QFN seeks to bridge the gap between Web2 user expectations and the capabilities of Web3 applications ^[1].

The project emphasizes maintaining decentralization while optimizing performance. It leverages nQUIC and WebRTC for networking, and it implements storage solutions designed for light clients to ensure accessibility for users on mobile devices and low-bandwidth connections ^[1]. QFN also incorporates forkless runtime upgrades to allow for continuous improvement and adaptation without network disruptions ^[1].

Products

• Native-First SDK: Aims to provide developers with tools for building responsive, real-time dApps ^[1].
• PolkaVM: An execution layer for smart contracts, based on the RISC-V instruction set, with an EVM compatibility layer for porting existing Solidity codebases ^[1].

Features

• SPIN Consensus Protocol: A hybrid consensus mechanism that combines Polkadot's security with a faster, cheaper finality gadget run by QFN's validators ^[1].
• Parallel Transaction Execution: Separates transaction validation from execution to increase speed ^[1].
• Verifiable Offchain Workers: Allows developers to handle complex computations off-chain while ensuring on-chain verification using zero-knowledge proofs ^[1].
• zkTLS Technology: A mechanism to commit Web2 data on-chain, leveraging cryptography used to encrypt website content ^[1].
• nQUIC and WebRTC: Networking protocols designed to create peer-to-peer connections ^[1].
• Light Client Support: Storage optimizations for light clients, designed to enable users on mobile devices or low-bandwidth connections to interact with the blockchain ^[1].
• Forkless Runtime Upgrades: Allows for continuous improvement of the blockchain's core functionality without requiring contentious forks ^[1].

Ecosystem

QFN utilizes a collection of blockchain primitives from the Substrate framework, including FRAME, which provides implementations for common functionalities such as asset management, balance transfers, atomic swaps, and account abstraction ^[1]. The network also employs SCALE, a codec designed for blockchain usage, and incorporates metadata to ensure compatibility between different runtime versions ^[1].

Ecosystem tools supported by QFN include block explorers (Subscan, Polkascan), developer tools (PolkadotJS), Helm charts for node deployments in Kubernetes, and a Metamask "snap" ^[1].

Use Cases

QFN aims to support a range of decentralized applications, including:

• Decentralized talent markets with immutable portfolios ^[2].
• Crowdfunding platforms with milestone tracking ^[2].
• Reputation-based financing models ^[2].
• Collaborative documents ^[2].
• Social networks ^[2].
• Job markets ^[2].

Architecture

QFN is built on the Substrate framework and incorporates the following architectural elements:

• SPIN Consensus: Aims to provide faster block times and finality compared to traditional Proof-of-Stake (PoS) systems ^[1].
• Parallel Processing: Seeks to improve transaction throughput by decoupling transaction validation and execution ^[1].
• Off-Chain Computation: Allows for complex computations to be performed off-chain with on-chain verification, reducing the load on the blockchain ^[1].
• Networking: Uses nQUIC and WebRTC to establish peer-to-peer connections between nodes ^[1].
• Light Clients: Designed to enable users on low-bandwidth devices to interact with the network ^[1].
• RPC Layer: Uses Cap’n Proto for efficient communication between clients and nodes ^[1].
• Data Storage: Uses a storage engine optimized for extracting and packaging Merkle proofs for light clients ^[1].

Tokenomics

The native utility token of Quantum Fusion Network is QF. The maximum supply of QF is 10 million tokens ^[3].

Utilities:

• Fees for processing transactions and storing data ^[3].
• Governance voting to determine changes to the network ^[3].

Governance: QF tokens are intended to be used for governance voting to determine changes to the network ^[3].
