Abstract

Abstract:

In this paper, a novel block file storage model is proposed by using erasure code technology, and is applied to the blockchain system. The storage system of blockchain is improved by using erasure code technology, and the stored block file is coded and stored in slices. With less data redundancy, the data reliability is not weaker than the original system, and the node’s demand for storage is reduced. Moreover, the model provides a block file decoding recovery scheme, as well as an adapted block synchronization strategy, which enhances the usability of the model. Finally, this paper tests the model by running in multiple fabric nodes, the results shows that it can reduce the storage space of the nodes and effectively improve the storage scalability of the blockchain system.

Key words: blockchain, erasure code, storage expandable
