On December 12, the Filecoin testnet was officially launched. According to the official website's Gratana computing power dashboard, on the first day, only seven mining machines worldwide received block incentives, three of them from Filecoin officials; only the official and two Chinese nodes participated. In this regard, the person in charge of the relevant mining machine manufacturer explained: "The entire test takes 3 months, so everyone is not anxious on the first day; as a technology company, the original intention is to better help Filecoin improve the technology, not to show off its own Speed. The most important thing about blockchain is consensus. Global consensus is gone. Can the project's valuation of 15 billion US dollars support it? "
