I think this is a great starting list!

Now that I've managed to spend a bit of time in the Enterprise Blockchain space
let me share a few observations:
   1. EOS seems to be the closest to fully realizing the vision that Blockchain
    is really a highly distributed compute platform in disguise. I
highly recommend
    reading about how they think of this problem space:
    Specifically sections on "Accounts" and "Deterministic Parallel
Execution of Applications"
    It wouldn't be a stretch to say that EOS's smart contracts are
much more of a

    2. I've seen a # of projects trying to simplify the job of smart
contract creation.
    Being a DSL for smart contracts if you will. However, see #1 -- I
really think
    that smart contracts are really serverless in disguise and as such
will require
    much more than a restrictive DSL. Still, the FP guys seem to be having quite
    bit of traction. A good example is here:

Well, hopefully we can just crowd-source the time ;-)
