Imo this "secret" is known by many people as I have seen so many censorship and misdirection campaigns throughout the years if people mention Adam being the one.
Him being Satoshi also makes bitcoin core seem more legitimate. He can guide his creation without being formally known as satoshi.
It is obvious. Especially if you have ever been a solo dev for an extended period of time (like adam was)
There is a ton more evidence but seems like no one really wants to dig into Adam.
Adam literally stopped updating hash cash and a year later Bitcoin is released... check his website on archive.org.
Its ok. I like that there is still conversation as to who it is. It gives protection to him since there likely wont be anything concrete (if hopefully he was slick enough)
A proof of stake system is essentially just a rehash on the earlier centralized digital cash systems where a quorum of key holders engage in a consensus that determines further updates to the system (including the set of keys allowed to authorize further updates).
We didn't need Satoshi to come up with that, that idea was already known.
Neither approach seems perfect, the important difference to me is that one approach, sans some technological advance like fusion energy, presents a major ecological problem that has existential risks for humanity.
