I agree the proof of burn is novel. I've seen it a lot too. At first it seems a little too good to be true but I gleaned their whitepaper and have realized the following:
Proof of Burn :
Supply, is forced to meet demand…
The fully decentralized Centric protocol regulates the Centric dual token economy, the notational $CNR price is predetermined per the algorithm, so the market values the ecosystem trading $CNS which provides on demand liquidity to $CNR holders.
● Centric Rise Price increases every hour.
Here's the key though:
● The more Centric Cash minted the faster Centric Rise burns.
● The number of Centric Rise in circulation can only reduce.
