@seven7hwave Technically the chain was unavailable for very-gas-heavy applications for a week or two during the 2016 Shanghai DoS wars, and an accidental 12 hour chain split happened a month later due to a consensus bug.
@seven7hwave 从技术上讲，在 2016 年上海 DoS 战争期间，该链在一两周内无法用于高耗气应用程序，一个月后由于共识错误发生了意外的 12 小时链分裂。
