基于Hyperledger Fabric与星际文件系统相结合的数据存储框架

Data Storage Framework Based on the Combination of Hyperledger Fabric and InterPlanetary File System

利用Hyperledger Fabric和星际文件系统设计了一种新的数据存储框架,使用Hyperledger Fabric的Level DB保存规模较小的状态数据,利用星际文件系统保存账本中大规模的交易数据,并改造了原来的数据存储和数据查询模块。新框架有效扩展了Hyperledger Fabric的存储能力,缓解了记账节点的数据膨胀问题。实验结果表明,新框架在保证安全性的前提下,增加了部分网络延迟,但相对于区块链存储的可扩展性而言,这个代价是可以接受的。

A new data storage framework was designed by using Hyperledger Fabric and InterPlanetary file system.The Level DB of Hyperledger Fabric was used to save the small-scale state data, the InterPlanetary file system was used to save the large-scale transaction data in the ledger. And the original data storage and data query modules were transformed. The new framework effectively expanded the storage capacity of Hyperledger Fabric and alleviated the data inflation of ledger nodes.The experimental results showed that the new framework increased some network latency on the premise of ensuring security, but compared with the scalability of blockchain storage, this cost was acceptable.
