I dont know how much time and money it needs to change this kind of code. I dont have the skills to do this. But i think someone maybe in the community have the skills.

SPS i think would be nice to fund something like this.

I agree with you, I also think it would take a very long time.

The most point i dont like on SBD is, the influence on inflation. I thing this can be kill Steem in a unlucky ( middrange) Bullrun.
