摘　　要：区块链技术是具有划时代意义的创新,一旦数据被录入区块链,就几乎无法被篡改或删除,这为重要信息的长期保存提供了可靠保障。然而,传统区块链节点间通信依赖直接连接,在面对链路变化时,会发生同步延迟,从而导致存储数据不一致。针对这一问题,提出了一种基于权威证明的许可链动态存储方法。在许可区块链网络中,节点需要存储大量的交易数据和区块信息,同时还需要保证链上数据的安全性和可靠性。为了更好地适应链路环境变化,该方法通过引入动态存储机制,更好地保证数据的安全性和完整性。实验结果表明,该方法可有效缓解时变链路环境中的数据不可用,并显著提高数据存储的安全性。Blockchain is an epoch-making innovation that cannot be tampered with or deleted once the data is entered into the blockchain.This provides a reliable guarantee for the long-term preservation of important information.However,the communication between traditional blockchain nodes relies on direct connections,which can cause synchronization delays when there are changes in the channels.This leads to inconsistent stored data.To address this problem,this paper proposes a novel dynamic storage mechanism based on Proof of Authority(PoA)for permissioned networks.In permissioned networks,nodes need to store a large amount of transaction data and block information while ensuring the security and reliability of the data on the chain.To adapt to the time-varying channel,the dynamic storage mechanism is introduced to ensure the security and integrity of the data.Experimental results show that the method can effectively mitigate data unavailability in time-varying channels and significantly improve the security of data storage.
