The Bitcoin system uses a fully replic-ated data storage mechanism in which each node keeps a full copy of the blockchain.As the number of nodes in the system increases and transactions get more complex,more and more storage space are needed to store block data.The scalability of storage has become a bottleneck,limit-ing the practical application of blockchain.This paper proposes a node storage scheme,called RESS,to integ-rate erasure coding technology into the blockchain to en-code multiple blocks.Under the proposed block grouping method,nodes can reduce the times of coded block decod-ing.In addition,the coding scheme based on Raptor codes proposed in this paper has linear coding and decoding complexity.The rateless feature of Raptor code helps to achieve high decentralization and scalability of the Bit-coin network.RESS ensures data availability,efficiency and blockchain robustness based on achieving storage space scalability.Experimental results show that the pro-posed scheme reduces the storage requirements of nodes by nearly an order of magnitude.
