Decentralized storage is a storage business model that uses distributed storage technology to store files or file sets in fragments on disk space provided by different suppliers. It advocates strong privacy protection, low storage cost, data redundant backup storage, high speed and other value propositions, and open source applications and algorithms. Only by implementing all of these propositions can centralized storage be replaced on a large scale. It helps to avoid single points of failure and transfer value of data. WEB 3.0 advocates data-centered, data value and privacy protection, and decentralized storage plays a crucial role in which data security and privacy protection corresponds to data redundancy storage and backup functions, and data value corresponds to the value transfer of file sharing. The scale and users of the centralized cloud storage market are growing rapidly. However, the centralized storage market has four defects: copyright cannot be guaranteed, data security cannot be guaranteed, service providers may stop operation at any time, and data lacks value. The business model for decentralized storage was born. Decentralized storage based on blockchain technology, through the decentralized architecture combined with the advantages of decentralization and decentralization to explore a balance between benefit and equity, so as to improve the security of storage; At the same time, the TPS of the storage network is greatly improved on the basis of the existing public chain and federation chain through the centralized processing of the storage and API interfaces outside the blockchain. In addition, seed nodes or file uploaders can be incentivized to value their data. Value proposition of decentralized storage decentralized storage represents a fundamental shift in the efficiency and economy of large-scale storage. Its value proposition is mainly reflected in the following aspects :(1) enhanced security and user privacy. Decentralized storage encrypts data not only to users and software terminals, but also to all links of the storage network. Users' privacy is protected by means of private network access keys and zero-knowledge proof. (2) Algorithms and code for the storage platform or network must be open source. As the 2C storage service has been occupied by centralized storage in most of the market, and as the entry threshold of open source projects is relatively high in the early stage, most of them are concentrated in the 2B end, only open source code can make the improvement of community and application form an effective positive feedback effect. If algorithms and code are not transparent, the storage network becomes decentralised. (3) Prevent data loss through redundant backup. Data is stored on different nodes, preventing data loss through data redundancy (storing extra copies in case of data storage or transfer errors). Architecture of decentralized storage The architecture of decentralized storage is TCP/IP protocol, blockchain, decentralized storage protocol, and application layer from the bottom up. The TCP/IP protocol corresponds to the network Layer of Layer 0, including the network topology and the transmission mechanism of transactions. Blockchain is Layer 1, which consists of cryptographic infrastructure (generally SHA-256 and other algorithms) and stored proof mechanism (consensus mechanism) from bottom to top. Decentralized storage protocol (service Layer) includes storage protocol (on-chain), retrieval protocol (off-chain), identity protocol (on-chain), content distribution protocol, incentive protocol, etc., including incentive allocation mechanism of Layer 1 and intelligent contract and script file of Layer 2. The top layer is the application layer, including client software and acceleration software.
