基于树形多链模型的数据一致性保证机制

iming at the problems of low performance and insufficient scalability of the blockchain single-chain model in diverse data processing, a multi-chain tree model and data consistency guarantee mechanism are proposed in this paper. Firstly, two types of blockchain structures, verification chain and data chain, are introduced in the model. Multiple data chains implement parallel classification and processing of diverse data, and verification chains implement consistency guarantees for transactions in data chains. Secondly, based on this model, a data consistency guarantee mechanism is designed, including a trusted anchoring method for inter-chain transactions based on hash lock and a rapid verification method for inter-chain transactions based on cross-connections. While improving the performance of the blockchain, it maintains blockchain's original advantages in terms of data security and credibility. Experimental results show that the model and mechanism have significantly improved transaction throughput and query efficiency compared to the traditional single chain architecture.
