and we need two new rpc-service interfaces here too, because vanilla server and stratum-server uses different interfaces.

so basically this will work;

public interface IStratumRPCService: IRPCService
public interface IVanillaRPCService: IRPCService

 _kernel.Bind<IStratumRPCService>().To<StratumService>();
 _kernel.Bind<IVanillaRPCService>().To<VanillaService>();
