Storj is an encrypted cryptocurrency-based file storage solution that stores files on a peer-to-peer network. Their goal is to leverage the benefits of blockchain to make online file storage more secure, faster, and cheaper. The network is powered by the Ethereum-based STORJ token.

Filecoin is developing a blockchain-based cloud storage solution. Filecoin tokens are used to power a marketplace for file storage that connects users through a bidding system. This pricing model is different from other blockchain storage solutions like Storj and Sia, that have set pricing for uploading files to their networks. Filecoin was created by Protocol Labs, a company with an established reputation for developing other network based storage solutions. They raised $205 million in a token sale. Filecoin has an innovative consensus mechanism that is a type of Proof-of-Storage, and is based on Proof-of-Replication (PoRep) and Proof-of-Spacetime (PoSt). This hybrid consensus system allows users to verify that files have been allocated to their own unique space in storage memory, and are being stored for a specified period of time.
