“Complicating matters is that unlike traditional corporations Jetzsch’s open-source codebase was written on the ethereum blockchain and free for anyone to use. No one has ever publicly claimed responsibility for the launch of this particular DAO that has come to be known simply as "The DAO", and no single person or group exists with the explicit authority or mandate to rectify the situation.”
“This means the task of cleaning up the mess has fallen largely to altruistic community members. Initially, two solutions were considered, though this has become more complex in recent weeks.”
