IOST

IOST 3.0 aims to build a robust, efficient, flexible PayPIN infrastructure, creating an open payment chain ecosystem. It comprehensively upgrades tech architecture: underlying security, subchain architecture, functional modules, developer tools; to meet diverse PayPIN needs, unleash Web3 payment potential, and drive widespread adoption.

Dynamically Enhanced PoB Consensus

Improves network fault tolerance and attack resistance, significantly enhances consensus efficiency and security. Supports large-scale concurrent transactions for Web3 high-performance.

Optimized Multidimensional Trust Scoring

Comprehensive scoring dynamically assesses node credibility based on response, contributions, assets, and activity.

AI anomaly detection monitors node behavior in real-time, identifies threats, and enhances attack resistance.

Multi-Source Randomness Fusion Technology

Fuses block hashes, node randomness, and external data (e.g., weather, off-chain events) to generate unpredictable random numbers.

Cryptographic techniques and multi-layer verification ensure fair and secure node selection, preventing attacks and manipulation.

Dual-Layer Consensus Verification Mechanism

Primary validator nodes are responsible for the initial verification of transaction legality and consistency.

Randomly selected backup nodes revalidate transactions to ensure consistency and prevent malicious node tampering.

Modular Subchain Architecture

Supports diverse architectures, offering high adaptability and scalability for payments and enterprise apps. Modular design boosts performance, ensures data security, and supports innovative IOST applications.

Permissioned Subchains

Designed for privacy protection and enterprise-grade scenarios with strict node management and access control for enhanced security.

Nodes undergo rigorous audits by Nexus DAO and are continuously evaluated by a reputation scoring system for high-quality participation, role-based access, multi-factor authentication, and robust data security.

Open Subchains

Supports dApps and high-performance, ideal for rapid innovation ecosystems.

Open subchains are managed by Nexus DAO, with transparent voting ensuring community participation.

Module Integration

Storage Module: Efficient, decentralized storage for PayPIN data.

Computation Module: Supports high-performance computing for transactions and smart contracts.

Identity Module: W3C DID standard, ensuring secure and private identities.

Efficient Cross-chain Protocols

Seamless IOST interoperability enables multi-chain collaboration for Pay PIN. Ensures secure, fast, reliable value flow between mainnet and subchains.

MSCIP (Main-Sub Chain Interconnect Protocol)

Standardized cross-chain message format ensures compatible, efficient mainnet-subchain data transfer.

Encrypted transmission and integrity verification secure cross-chain data.

Cross-chain validator nodes coordinate and validate mainnet-subchain transactions, ensuring data consistency.

SCCLP (Sub-Chain Cross-Linking Protocol)

Subchains directly communicate and share data, enhancing dApp collaboration.

Distributed Relay Nodes: Facilitate data synchronization and transaction validation between subchains via multi-point collaboration.

Multi-Sig: Secures cross-chain transactions, preventing single points of failure and attacks.

DRN (Decentralized Relay Network)

Dynamic Load Balancing: Dynamically adjusts data paths based on traffic for higher efficiency.

Data Encryption and Signing: Crypto secures cross-chain data transmission.

Relay Node Configuration: Distributed consensus validates cross-chain transactions, ensuring transparency and reliability.
