-A user can earn a validator spot only by if the below conditions come into play:

-1. When a validator decides to unstake from the network, or
-2. Wait for the auction mechanism and replace the inactive validator.

-The minimum stake depends on the auction process where one user outbids another.
+To become a validator in the PoS network, you'll need to hold and stake a minimum of 10,000 POL tokens, and go through an admissions process to ensure network security."

-In order to start a bid or bid higher on already running auction, this function is used. Auction period runs in cycles like `(auctionPeriod--dynasty)--(auctionPeriod--dynasty)--(auctionPeriod--dynasty)` so it *must check for correct auction period*.

-`perceivedStakeFactor` is used to calculate exact $factor*old stake$ (note currently it is by default 1 WIP for picking the function). *Must check for auction from last auction period if any still going on* (one can choose to not call `confirmAuction` in order to get their capital out in the next auction). Normally continuous english auction is going on in a `auctionPeriod`.
