What does this mean? Everybody competes with each other to find the next block afaik. Do you mean can somebody skip the next block and mine the next 2nd/3rd block instead? How would that block be valid if the previous block is yet to be found though? You might be referring to orphan blocks too I guess[1]. CMIIW.

Seeing you've forked Bitcoin on your previous posts, I think you're quite knowledgeable when it comes to mining software. Some of you're questions, especially the software part can be answered easily if you check out the GitHub page imo.
