论文摘要
随着区块链应用的开发，区块链中文件存储的要求迅速增加。已经提出了许多协议，包括Filecoin，Arweave和SIA，用于为区块链应用提供可扩展的分散文件存储。但是，现有协议并没有很好地承诺可靠性。受保险概念的启发，我们创新地提出了一个分散的区块链的分散文件存储协议，称为FileInsurer，以实现可扩展性和可靠性。在通过分布式存储中确保可伸缩性的同时，FileSurer通过增强鲁棒性并充分补偿文件丢失来确保可靠性。具体而言，在轻度条件下，我们证明，即使一半的存储空间崩溃，也应补偿所有文件的0.1 \％值。因此，仅存储提供商只需要支付相对较小的存款才能支付潜在的文件损失。由于存款负担较低，存储提供商有更多的激励措施参与存储网络。 FileInsurer可以在行星际文件系统（IPFS）的顶层中运行，因此可以直接应用于Web 3.0，无填充令牌和元视频中。
With the development of blockchain applications, the requirements for file storage in blockchain are increasing rapidly. Many protocols, including Filecoin, Arweave, and Sia, have been proposed to provide scalable decentralized file storage for blockchain applications. However, the reliability is not well promised by existing protocols. Inspired by the idea of insurance, we innovatively propose a decentralized file storage protocol in blockchain, named as FileInsurer, to achieve both scalability and reliability. While ensuring scalability by distributed storage, FileInsurer guarantees reliability by enhancing robustness and fully compensating for the file loss. Specifically, under mild conditions, we prove that no more than 0.1\% value of all files should be compensated even if half of the storage collapses. Therefore, only a relatively small deposit needs to be pledged by storage providers to cover the potential file loss. Because of lower burdens of deposit, storage providers have more incentives to participate in the storage network. FileInsurer can run in the top layer of the InterPlanetary File System (IPFS), and thus it can be directly applied in Web 3.0, Non-Fungible Tokens, and Metaverse.
