🔄Hybrid Consensus Mechanism

Traditional blockchain networks rely on either Proof-of-Work (PoW) or Proof-of-Stake (PoS), both of which introduce trade-offs between security, decentralization, and scalability. PoW-based networks require significant computational resources and high energy consumption, while PoS mechanisms, despite being more energy-efficient, often suffer from validator centralization and network congestion. Nexchain implements a hybrid PoS model that integrates AI to dynamically adjust staking requirements, validator selection, and transaction prioritization.

AI-based transaction prioritization enables real-time optimization of network activity, allowing high-utility transactions to be validated more efficiently while maintaining decentralization. The consensus model also incorporates adaptive block validation, which optimizes network security by modifying transaction finality parameters based on network conditions. By reducing redundant computational processes, this hybrid model minimizes energy consumption and improves transaction processing speed. The expected transaction finality Tf in Nexchain can be approximated as:

where tv represents the average validation time per transaction, 𝑛 is the number of active validators, λ is the AI optimization coefficient, and 𝑚 denotes the transaction throughput of the network.
