There is already a PoW crypto that is actually private called Monero. It uses ring signatures to sign transactions and rotating public keys to keep public keys private. It also happens to be relatively stable since it’s basically the only crypto that people use as a currency (generally to buy illegal contraband online). It’s PoW though, so has the energy consumption issues.
Since it’s PoW, though, it still consumes buckets. Something I thought looked cool was Chia coin, which somehow uses hard drive space as a consensus algorithm which saves a ton of electricity, but I haven’t read the whitepaper on that, so I don’t fully understand it.
