Filecoin
Filecoin is a decentralized peer-to-peer network designed for storing and retrieving files through economic incentives and cryptographic proofs of storage, providing an alternative to centralized cloud storage providers.[1][2]
Developed by Protocol Labs under the leadership of founder Juan Benet, the project originated in 2014 as an extension of the InterPlanetary File System (IPFS) and raised a record $257 million in its 2017 initial coin offering, including $52 million from a presale and $205 million from the public sale.[3][4]
Despite initial plans for a 2019 launch, Filecoin experienced substantial delays due to technical complexities in implementing its proof-of-replication and proof-of-spacetime mechanisms, ultimately deploying its mainnet on October 15, 2020.[5][6]
The network uses its native FIL token to facilitate storage deals between clients and storage providers (miners), who earn rewards for committing hardware to verifiable data preservation, with retrieval markets enabling efficient data access.[7][1]
By 2025, Filecoin has established itself as the largest decentralized storage network, boasting exabytes of total capacity, rising utilization to around 29% in early quarters, and ongoing upgrades like the Teep version for enhanced efficiency, though it has faced scrutiny over slow adoption and mining barriers.[8][9][10]
