The thing was halting my programming lately is I wasn't satisfied that I had solved the permissionless and decentralization principles. But I think sending PoW with each transaction solves it, but I need to go over all the details again to make sure I haven't missed something.
If I feel I have the Bitcoin killer and something that can really help the world, then I will be motivated to program. I don't want to waste my effort. I am in extremely bad situation in my life and I can't afford to go down any nonproductive forks at this juncture of my life.
It seems like you have hit an impasse, but without knowing the details of the problem, we are powerless to assist. In principle, if only you can mine your own transactions, then decentralisation increases and sticking with POW ensures permissionless behaviour - is there some related subtlety that you have encountered?
