Distributed storage = decentralized storage, disperse and store data on multiple independent devices, break the monopoly of centralized storage, break the monopoly of Internet super enterprises, the network stores data and content in every corner of the world, and solve the storage server as a system performance bottleneck.

Decentralized storage corresponds to centralized storage, such as Alibaba Cloud, Tencent Cloud, Baidu Cloud and other products on the market. Download to client. The disadvantage of this is that it is easy to cause network congestion, and data is easy to be lost, stolen or rewritten. Today, the control of the Internet is increasingly concentrated in the hands of a few large technology companies. For individuals, it is not democratic enough, and they lack control over their own information.

The decentralized storage is distributed by many nodes participating in the storage, which can get rid of the limitations of huge centralized storage and geographical location. The hash algorithm of blockchain technology can greatly reduce the file size and increase the capacity. At the same time, encryption technology Make data privacy stronger, and data will not be tampered with. Decentralized storage is a supplement to centralized storage, not a complete replacement. Internet users can experience a freer, more innovative, and more democratic experience.

Several popular projects in this field are IPFS/Filecoin, BTT, AR (Arweave), Crust, Storj, MW, etc. Filecoin is one of the star projects. Its main network is close to launch, and everyone is already ready to snatch the first wave of FIL tokens.
