I know that sounds appalling, but do you think that it is possible that he did that? If he did do that, what exactly could he/they have the ability to change with so many people constantly maintaining Bitcoin core? If something like that was ever a possibility could BTC core developers reverse any changes made or prevent? I guess I’m just curious how many security measures are set in place to prevent things like that from every happening. Could they prevent or reverse a 51% attack as well?
Your fears are groundless.
The fact is that so many people would never believe in Bitcoin if its code was unavailable for viewing. Nevertheless, the full project code is posted on github. Programmers of C++, Python and other programming languages have studied every line, thanks to this, understanding how to make other cryptocurrencies has become easier!
Therefore, Satoshi is not an attacker, and of course, cannot seize control of Bitcoin.
