Why do keep fixating on "longest chain"? ? ?
The longest chain does not determine the accepted chain. With no disrespect intended it is clear that you do not even have a basic fundamental understanding of 51% attacks or any other for that matter. Everything proposed as "protection" in this thread is flawed to say the least.

Correct me if I am wrong, but the longest valid chain is the accepted chain no?
No if it's behind the last checkpoint for instance.
