And always remember the main point for me (economics aside): We don't need the 45% PoW force anymore. DASH as a project don't need to waste the energy for it. And that's something important for me, and I'm sure for more people out there.
Not wasting energy is also very important for me. But I also like PoW for 'philosophical' and monetary reasons related to competitive mining and scarcity giving value to a blockchain. That is what currently motivates me to study some interesting solutions that keep harnessing PoW while not wasting energy.
The PoW is still necessary in Dash because it provides an entropy pool for the randomness used by Chainlocks (for random selection of LLMQ, masternodes, etc).
It is also a fall-back method when for some reason (very improbable but it can happen) Chainlocks fail to lock the block.
Are there other reasons for PoW now that we have Chainlocks? Where can I find more information that would allow me to estimate how much entropy is needed?
If someone knowledgeable would be so kind to point me in the right direction I would be grateful.
