Filecoin (FIL) is the incentive layer of the IPFS (InterPlanetary File System) interstellar file system and is the token of IPFS. The goal of Filecoin is to use IPFS technology to create a decentralized storage network, so that stored files cannot be maliciously tampered with, stored permanently, and accessed at any time. In 2017, Filecoin completed a total of US$257 million in financing, setting a record in the history of the currency circle.

QFIL is a Filecoin token based on the ERC2.0 version launched by QuickCash. The current total supply is 10,000 pieces (obtained in the arms race). After the Filecoin mainnet goes online, it can be exchanged for FIL mainnet currency at a ratio of 1:1. .
