<p>Basically, yes. But it doesn't have any dramatic effect and it's almost certainly over by now.</p>

<p>There's no secret backdoor. There's simply no place to hide one. But it's possible the developers had a head start on figuring out how to execute the mining algorithm quickly.

Is it possible that the Bitcoin creator (or developers) have an algorithm that allows computers to generate coins easily, but intentionally published only the current difficult mining algorithms. And, in that way, have left themselves a backdoor way of generating bitcoins once the algorithm became popular?
