Technologically, this is great. Trustless proof-of-stake seems like another new innovation that makes POS more convenient because we no longer have to maintain an online node/server to stake for us. However, just like the ICO HYPE back in 2017, this seems doesn't seem to be anything that could be game changing unless it is properly executed with real world adoption.
What use is a cryptocurrency, how easy it is to stake with, if nobody uses it in the real world?
