3.6 Scalability and Network Security Optimization Strategy
As a platform dedicated to the digitization and on-chain management of Real World Assets (RWAs), RealAsset Chain (RAC) requires a robust infrastructure capable of handling large-scale asset interactions while ensuring system-wide security and stable network performance.
To meet these dual demands, RAC has implemented a multi-layered and multi-mechanism technical framework focusing on both scalability design and network security enhancements.
1. Optimized Consensus Mechanism
RAC adopts a hybrid consensus architecture combining an enhanced Proof of Stake (PoS) mechanism with Byzantine Fault Tolerance (BFT) protocols. This ensures high transaction throughput while maintaining node consensus security and data consistency. Key features include:
Low latency and high throughput: Capable of processing thousands of transactions per second (TPS), supporting high-frequency asset trading scenarios
Strong fork resistance: BFT ensures finality and immutability of confirmed blocks, preventing double-spending attacks
Energy-efficient: Significantly lower energy consumption compared to PoW models, aligning with global green finance standards
2. Secure Node Architecture
To safeguard node stability and ensure secure operation within the RAC network, a multi-tier node protection system has been implemented:
Layered Node Roles: Includes validator nodes, observer nodes, light clients, and archival nodes—designed to balance performance and redundancy
Dynamic Reputation Scoring: Node behavior is continuously evaluated, with penalties or automatic demotion applied to underperforming nodes (e.g., delayed responses or incorrect block proposals)
Encrypted Communication Channels: All inter-node communication is protected by TLS encryption and message-signature verification, mitigating risks of man-in-the-middle attacks or data tampering
3. Platform Scalability Strategy
Modular Architecture: Core components such as smart contracts, data storage, and identity management are designed as independent modules, allowing for isolated upgrades and parallel deployment—minimizing downtime and ensuring system continuity
Sidechains and Rollup Integration: Application-specific logic is offloaded to Rollup subchains or industry-specific sidechains, improving mainnet efficiency and reducing congestion
Off-Chain Computation Support: Integrates off-chain computation frameworks like zk-Rollup and Validium to handle large data sets, reducing the computational burden on the main chain and improving response time
4. Security Defense and Monitoring Systems
RAC maintains a proactive defense posture through comprehensive security mechanisms, including:
Multi-Signature and Cold/Hot Wallet Separation: Used for managing platform privileges and safeguarding assets, preventing systemic risks due to private key leakage
DDoS Protection Infrastructure: Implements traffic filtering and behavior recognition modules to defend critical endpoints from malicious disruptions
Real-Time Auditing and AI-Powered Anomaly Detection: Employs machine learning models to continuously monitor network behavior and identify potential threats in real time
Through the combination of optimized consensus protocols, tiered node security, modular and scalable system design, and comprehensive security measures, RAC not only delivers high-performance operations but also builds a fortified defense system. This provides a solid, future-proof foundation for large-scale on-chain RWA asset management and long-term platform growth.
