The bitcoinR network will move to a Proof of Stake (PoS) consensus mechanism following the Proof of Work (PoW) mining periods that begin in Q1'2019 and are projected to end in 2022. The PoW mining period will conclude upon the successful mining of approximately 21,000,000 XBR.
Over time it will be more energy efficient and secure for the platform to adopt a PoS consensus model. In addition, PoS will give the bitcoinR team the ability to more precisely control economic parameters to stabilize the XBR currency value and account for instances of lost coins or price fluctuations that might create instability in our coin's pricing.
The bitcoinR team is presently evaluating best-of-breed PoS strategy alongside new technological improvements to better understand how we might best design an ideal consensus protocol. As always, we will strive for transparency by socializing with the bitcoinR ecosystem before making any final decisions or plans to ensure we are delivering the best solution possible.
