On September 18, the anonymous forked project Filecoin Vision published an article titling "Filecoin Vision Manifesto" via GitHub. The manifesto announced that it will implement numerous improvements and also stated the problems of Filecoin including: 1. The mineable share has dropped from 70% to about 30% at the beginning of the mainnet; 2. The pre-mortgage and post-block rewards are released linearly; 3. Window PoSt fails within half an hour result in a token penalty, which must be repaired the next day; 4. The commitment data verified by a validator has the storage in 10 times; 5. The Protocol Lab tends to use ethics to restrict the behavior of miners, rather than rules on the chain; 6. The Protocol Lab owns 15% of the tokens, and the Foundation owns 5% of the tokens. In this regard, the IPFS Force Zone issued a post saying that the purpose of Filecoin Vision is to make a series of adjustments to Filecoin's economic model through the fork, so as to reduce the pressure of miners to a certain extent and obtain more benefits. Some head miners also revealed their thoughts in this regard in media interviews. It is foreseeable that many forked projects will appear after the Filecoin mainnet is launched. But no matter what, they still have to resist those forks that are purely for profit.
