In a nut shell. Pandacoin is a Proof of Stake coin that had extensive development work back in 2014. However just as was the case for Bitcoin, Dogecoin and many other coins, it's original development team moved on to other things and the community picked up the pieces and continue to build from where they left off.

The principles behind Pandacoin were and remain.

1. Honesty
2. Fairness to all people
3. Integrity
4. Courage in the face of corruption
5. Love for furry ferocious black and white animals
