STAKING PERI
Staking: Open a Position
PERI  stakers can lock their PERI COIN into the Peri Finance protocol Staking Dapp and take on a debt position in the shared pool of the combined USD value of all Pynths . After Successful staking, they  issued pUSD that represents their current debt position in USD. 
As the prices of underlying pynths fluctuate with oracle updates, the size of the debt pool fluctuates too, It means that staker's debt independent from the amount of pUSD that was issued.
To consider the risk stakers take on by being exposed to a shared debt pool, they are rewarded each week in the form of pUSD trading fees and PERI inflationary rewards .
