There is auxPow option which uses the PoW that already exists. Problem there is that we need to have enought economical motivation for pool to include us and mining centralization.
My concern is that if we move back to regular PoW, will we still be the "energy efficient coin"? I'm concerned that returning to regular PoW would contradict that.
That's PoS about. The ones who have more stake are the most interested in keep the blockchain running.
Other option is the masternodes.
What I mean is that if the PoS work ends up being *only* done by those with the most coins, and they get so much priority others literally can't stake, then they become, by default, "masternodes". I'm not saying it shouldn't exist to some degree, just suggesting an equation that could ensure that it is not programmed into the system that "only" those individuals can stake but that is be programmed in to ensure others can still contribute (especially if the big dogs aren't available at a given moment).
What happens when no one is staking at given time and people want to buy things with Teslacoin?
We expect that doesn't happen
It has been happening here and there the last couple of weeks, I was merely pointing out, in my prior post, ways to impede and or eliminate that regardless of the fluctuations in the network because, right now, its the algorithms that are allowing these dead times right now; and its not for lack of wallets open, its for lack of available staking coins to use to build blocks.
If you don't prioritize in some way then what decides who gets to win the "battle" of the hashes and gets the fee for the block over everyone else?
Shall it be the one who gets it done fastest? Oh wait, now we're back to PoW.
See the cycle?
I see. Yes, fee distribution it's a point we need to work on...
The first node to distribute the tx get the fee is an option.
What I mean is it goes back to the PoW (and therefor lack energy efficiency) if we just say whoever does it "first". Even if we just let the wallet program "handle" this PoW mining it'll still be whomever has the fastest processor the wallet is running on who will get the tx fee, therefor starting a race to have the fastest computer and spend the most electricity to complete the node first. That's why I was thinking something that pivots off of Proof of Stake, but that is programmed not to only allow those who have the most coins to be the only ones to perform proof of stake either. Any big dogs who suddenly send their coins to another wallet or sell them would cause a huge drop in the efficiency of the network if others couldn't pitch in at that time.
