Current requests:
Change S4C to 100% - I think I will likely do 75 or 90% for the first change. Then if that goes well change to 100%. But I can bump it, yes.
Lower CPU - This will be one of the first one. Multiple changes for this.
Lower Memory - Most important but also most difficult. Will take much time, but will begin to investigate this and see what can be done. Need help from the crowd on this one. What POS coins are out there that have the least memory? New coins don't count. Have to have few years under their belt.
What else?
GenStake is another PoS/PoW coin that runs much less CPU and memory than HBN. 2GiveCoin runs with very little resources but is much differently structured kind of PoS/PoW coin. Hyperstake and Truckcoin are also lower in memory and CPU use but do not use PoW. (Truckcoin runs higher on CPU use) The GreenCoin daemon runs with very little CPU and memory use but is also PoS only.
However greencoin has problems of its own which i need to take care of when i get time. Its based on the old blackcoin. Likely going to be upgraded to the new blackcoin base when i have some time. The main issue with it is that peer discovery isnt working (may be due to faulty seed nodes) and the blockchain sync stalls at certain blocks
