Filecoin is a cryptocurrency and blockchain platform that aims to provide a peer-to-peer file storage system.

Filecoin was first described in a white paper published by computer scientist Juan Benet in July, 2014. It was later described in an updated white paper published in July, 2017. Filecoin is the proposed incentivization layer for a new decentralized storage network that would allow users to pay for the peer-to-peer storage of their files. The Filecoin network is being developed by Protocol Labs, a U.S.-based company founded by Juan Benet and focused on building internet infrastructure technology. Filecoin runs on the InterPlanetary File System (IPFS) protocol, a peer-to-peer file storing and sharing protocol developed by Protocol Labs and launched in February, 2015.
