What is blockchain selfish mining (selfish mining)

"Selfish mining"

When the chain obtained by "mining" is longer than the chain of others , do not publish your own chain, and continue to mine on your own chain;

When the chain with its chain and others published more than equal length or shorter , immediately issued its own chain, and continue "mining" in the chain of others have been released.

 

Then, an attacker close to 1/4 of the computing power will jeopardize the correctness of Bitcoin
