The blockchain and the money paid out is all founded on Steem
Steem dollar and steem power is based on Steem
Steem power is just steem that has been powered up or vested
into your Steemit account
This means you have given your Steem to the collective vested pool of all steem power.
Because you gave your Steem to the collective pool your influence is much higher on the website
Your vote can be worth $5.20, $40 etc the more steem you have given to the collective Pool the more your vote is worth
