Another fall down for Bitmain who decided to create manufactures ASICS secretively for Sia mining in 2017 . In response Sia community decided to make a hard fork leaving Bitmain and another manufacturer outside the Sia market. The only one staying operational will be a 16nm chip from Obelisk manufacturer, who will become the new manufacturing monopoly for Sia.
"Sia is forking today to reprimand the current ASIC monopoly for the damage it did to the Sia community, to make whole the supporters of Sia’s community ASIC project, and to send a clear message to all future Sia ASIC manufacturers: we will not tolerate an abusive ASIC monopoly" said - David Vorick Sia’s lead developer
