Why It Matters: The news follows Musk recently tweeting that Tesla would stop accepting Bitcoin for its electric cars due to the concerns over the impact of the network's operations on the environment. He said he is looking at other digital currencies that use less than 1% of the energy that Bitcoin does.
PoS cryptocurrencies such as the ones that just saw this growth — which actually brought them both to new all-time highs — pride themselves on not needing powerful and power-hungry supercomputers that "mine" them and secure their network. Instead, network security is ensured by low-power computers that lock (stake) digital assets that will be lost if the network operators misbehave — by, for instance, approving transactions that should not be approved.
