Abstract

Blockchain technology has received great attention in recent years. However, the data volume of blockchain grows continuously due to the features that cannot be deleted and can only be added. Currently, the total size of Bitcoin blockchain ledger has reached 200GB. Its high demand for storage space and bandwidth to synchronize data with the network prevents many nodes from joining the network.This is not only not conducive to the expansion of this decentralized network, but also becomes the bottleneck of the development of blockchain technology. This paper proposes an IPFS-based blockchain data storage model to solve this problem.In this paper, the miners deposit the transaction data into the IPFS network and pack the returned IPFS hash of transaction into the block. Utilizing the characteristics of the IPFS network and the features of the IPFS hash, the blockchain data is greatly reduced. The scheme is applied to the Bitcoin blockchain. According to the experimental results, the compression ratio can reach 0.0817. According to the analysis, it also has good performance in terms of security and synchronization speed of new node.

基于ipfs的区块链创新存储模型

区块链技术近年来受到了极大的关注。然而，区块链的数据量却在不断增长，因为区块链的特性是不能删除的，只能添加的。目前，比特币区块链总账的总规模已经达到200GB。数据同步对存储空间和带宽的要求很高，导致大量节点无法加入网络。这不仅不利于这种去中心化网络的扩展，也成为区块链技术发展的瓶颈。本文提出了一种基于ipfs的区块链数据存储模型来解决这一问题。在本文中，矿工将交易数据存入IPFS网络，并将返回的交易的IPFS哈希值打包到块中。利用IPFS网络的特点和IPFS哈希的特点，大大减少了区块链数据。该方案应用于比特币区块链。实验结果表明，压缩比可达0.0817。分析表明，该方案在安全性和新节点同步速度方面也具有良好的性能。
