No, sats (represented as blood) is the highest valued currency in game. We introduced a stock market style setup where players can place a buy order for any in-game item (let's say a gun) and then other players can sell that item to the other player for sats(blood). Anything in the game can be purchased with sats from other players creating a PoW where the player finding and producing tools/resources gets the reward from another player that needs those items.
