Can somebody tell me what EV means and what the graphs represent?

Does p=0.9 means that I look 0.9 of my stake for the one branch and 0.1 for the other? Where does this locking happens? Why can't I vote for both branches with my "whole steak"? (if this steak thing is correct).



EV means expected value. It is the average you will receive if you repeat the experiment a large number of times.

p=0.9 means if you choose that branch you have 90% probability of it being the correct one.

The locking happens when you "vote".

You can vote both alternatives. They analyze that case and propose possible solutions to prevent that behavior.

  • But why is the probability not 0.5 for both branches? If everyone is following the same procedure on mining on both?

  • It is just an example. Everybody should have about the same probability to generate a new block. Once it was generated how it propagates depends on external factors like network connectivity between nodes.
