This is really not gonna take that long to do, the hard part will be getting people to run enough witness nodes. Other than that, I am pretty sure I just need to poke around until I find the 'Chain ID' code which will prevent, in the case of someone misconfiguring and adding steemit steemd nodes to the list... this actually happened when golos forked.
Once I'm done getting this up and running, and we have enough people, then the issue will be we need to have devs working on fixing/rewriting the code, because I figure we have 6 months to change the way the database works, or it will be poo-poo again for the new chain.
I want to move on to DIV as soon as possible, I just need to go at this hammer and tongs until enough people realise that a new world beckons, and they can migrate to it, away from this nest of premined fake steem power.
