We haven’t done too much direct research on EOS, but it is one of the projects we will consider doing an analysis on soon. One of the biggest questions regarding EOS is its use of Delegated Proof of Stake. I have been told by a number of very smart people that there are issues with this PoS model. Take a look at this discussion regarding it: https://github.com/cosmos/cosmos/issues/43
However I haven’t done enough personal research to comment further. We’ll let you know when we publish an analysis on EOS!
