AI Technical Summary

Technical Problem

Existing sharded blockchain systems fail to effectively consider differences in transaction types when allocating accounts, resulting in uneven resource consumption, difficulty in coping with complex and ever-changing transaction patterns, and impact on system scalability and performance.

Method used

By employing graph attention networks and deep reinforcement learning algorithms, combined with transaction type weights, an account allocation strategy is optimized. The account migration process is modeled through a GA-PPO agent to achieve dynamic account allocation.

Benefits of technology

It improves the scalability and performance of sharded blockchain systems, optimizes resource utilization, and reduces cross-shard transaction rates and system load imbalance.

Abstract

The application provides a kind of sharded blockchain dynamic account allocation method considering transaction type, comprising: based on the consensus protocol within the sharding of sharded blockchain system and each transaction type weight executes transaction, generates local transaction graph;Aggregating all local transaction graphs to build a global transaction graph, and extracting a feature vector representing the system state from the global transaction graph through a graph attention network (GAT) and outputting an account allocation strategy prediction result;Optimize the prediction result through GA-PPO agent to obtain the optimization result of account allocation strategy;Based on the consensus protocol within the sharding, the decision result of the mapping relationship between the account and the sharding is generated according to the optimization result of the account allocation strategy, and the account migration operation is executed according to the decision result.The process data of the account migration operation executed according to the new strategy can also be recorded, and the recorded process data is used for continuous training of GA-PPO agent.The application optimizes the dynamic account allocation strategy in the sharded blockchain system, and improves the scalability and performance of the system.
