That is one of the biggest weaknesses of Bitcoin . The reference implementation is the specification . That means , by definition , that any bug is correct . It also makes auto testing difficult . In a serious project , you create tests from the specification , independent on the implementation . That is a major quality improvement . As it is now , you would create test cases from the implementation , which would kind of be guaranteed to succeed . But what value is that ? <| sep |> My Nexus 6 P is rooted and I flashed something that adds all the Pixel features <| sep |> They all have jobs <| sep |> 311 the blitz X , Ninurta XIII , Artemis Bow Vwanted artemis bow , so all is good . <| sep |> Savage is almost as bad as Lalas ffs .
