The start itself was quite honest with respect to future users, that is, there were no such things as premine, instamin. No part of the reward for the mined block goes back to the development of the project. After the launch, the founder of Monero proposed changes to the work, which seemed to many to be wrong.

This core group has been overseeing the project ever since.</p>
