Earlier news, the Steem team launched a soft fork last week. But there are voices saying that large exchanges including Binance, Huobi, and Poloniex are using their voting power to raise the witnesses related to Steemit to the top 20. Sun Yuchen was accused of bribing the exchange.
Binance CEO Zhao Changpeng acknowledged the incident on Twitter and said Binance may withdraw its vote in light of the community's response. This operation requires coordination between people in several different geographical locations, and may take a little time. He then added in another tweet that we didn't take a penny and thought it was a normal upgrade / fork.
