The crypto of today can be called the little blockchain engine that could: Mina Protocol ( $MINA )

Summary: Mina is a lightweight, proof of stake, privacy focused blockchain with smart contracts and no, this is not even its final form.

Without trying to prove things that I have no knowledge about, the Mina blockchain has what are called "zero knowledge proofs." Which enables you to "prove a secret on the blockchain without telling anyone what exactly that secret is."

With so many features Mina seems like the blockchain of the future and may very well be here to stay. Or it might run out of stamina along the way.
