Distributed storage is a data storage technology that utilizes the disk space of every machine within an enterprise via a network, combining these distributed storage resources into a virtual storage device. Data is stored across various locations within the enterprise, making distributed storage a critical infrastructure for Web3.

In addition to the leader Filecoin, other notable projects in the distributed storage space include Arweave, Sia, Storj, Bluzelle, Crust, and Chia, each with its own advantages.

FIL: Founded by Juan Benet in 2014, the project IPFS is a peer-to-peer distributed network transmission protocol aimed at creating a more open, fast, and secure internet. It has garnered support from major investors such as Sequoia Capital, Stanford University Capital, YC Capital, Winklevoss Capital, and Distributed Capital. Filecoin is a cryptocurrency built on the IPFS network, serving as an incentive layer to reward Filecoin miners for their mining activities or to pay for transaction fees generated on the IPFS network. Currently, it is the leader in the distributed storage space.

Arweave: Its founding goal is to permanently store data, including web pages, emails, photos, posts, and more. Arweave employs the Proof of Access (PoA) consensus mechanism, establishes an audit system for uploaded transaction data, and has created a profit-sharing community that issues Profit-Sharing Tokens (PST).

Storj: A decentralized cloud storage platform comparable to Amazon S3, its primary user base consists of all users of Amazon S3 storage services. Compared to Amazon S3, Storj can provide the same services while offering lower costs, decentralization, and enhanced privacy protection.
