Hello. I was suggested to ask here.

I'm diving into the new Blockchain technology, which seems like an interesting underrated concept. It is called Proof of Memory.
The core idea is to use PoW but collect hashes into the memory for some timeframe and then when it is needed QUICKLY get the best hash. It allows to mine blocks faster.
Also PoM reuses the same pre-mined hashes to validate multiple blockchains in parallel. It allows unlimited scalability.

I published mind map with my impressions on my blog:

Detailed description of Proof of Memory on the project website:

I want to ask the community - what do you think about it?
Is it an underrated concept to make the PoW more "green"?
Considering that the PoS has it's problems can this PoM concept give the second life to the PoW?
