Regarding pow and pos, I think the final game is still pow as the final choice.

pow is mainly about ideals, philosophical disputes, not market disputes. The quantum resistance of hash function signatures cannot be designed to mine for thirty or fifty years in pow mining, mainly because the signature length of the hash signature is too large. Therefore, the hash function signature should follow the pos technical route for full original management.

The only thing that can be both pow and quantum resistant can only be rainbow signatures, and only rainbow signatures can be used efficiently in the cryptocurrency scene for a long time.
