Each validator votes from its own node, where its key is. Press the button if this page is open as you, or copy the command and run it there.
Every proposal this chain has finished with, most recent first. Open a row for what it would have done, the tally it got, and the message as the chain holds it.
One validator can freeze in a single block. It is fast on purpose — stopping money moving is reversible, so it is worth being wrong about.
Taking somebody's funds is not. These need a supermajority of voting power and, where required, evidence — and once executed they cannot be undone.
Read from the chain's own enforcement parameters and gov parameters at every refresh, not from a description of how the modules are meant to work.
