The Folder protocol (FOL) is designed to function as a second-layer solution for decentralized storage network; an incentive layer on top of IPFS, which enables to provide storage infrastructure for any data. Folder protocol will benefit especially for decentralizing data, building and running distributed applications, and implementing smart contracts that operate on large volumes of data. Additionally, it also benefits the users for the faster retrieval and wider distribution of content; anyone can participate contributing to the Folder protocol ecosystem by node operating, mining and offering storage services.
