@haejin Wrote a small piece that might be interesting for "investors" - got access to an Intel program to test STEEM on their hardware. Technically STEEM blockchain is the first to "officially" do this. ie, there are instances of this being tested earlier but not in an "official" means that can be used for PR etc.
