I think a better solution is to create a protocol that doesn't rely on a
proof-of-work function. Still something of an open problem though.

I think the proof-of-stake approach used by systems like Tendermint are
interesting, and really what's holding back those sort of protocols now is
the simple fact that engineering a distributed consensus algorithm is
incredibly hard. Tendermint doesn't have a formal proof of correctness (in
terms of e.g. TLA+)
