A complete review of the ARC attack process reveals that there were many misconceptions about @ Lighter_xyz among English bloggers yesterday 1. Believe that Lighter LLP is different from HLP and will not accept positions In fact, all contracts inevitably involve the risk of insurance fund liquidation, and the balance needs to remain non-zero for a long time. Why was OI initially restricted and then cancelled Due to restrictions on opening positions, long positions are almost exclusively held by the same user, who does not close their positions; And bears are dispersed retail investors Closing a short position is a long order, so restricting opening a position will not cause a price drop, but may actually increase the value of long positions and pose greater risks to LLP Why change the funding rate Let the bulls level instead of the bears. So using OI restrictions is useless, using funding rates as punishment is useful. 4. It is believed that the attacker is bullish on Lighter and bearish on Binance can't. Although both OIs are growing, their contracts are positive premium+positive funding rate, so both are dominated by long positions. If the directions are different, and his position size is used in two directions simultaneously, it must be a positive premium for Lighter and a negative premium for Binance.
