Xem and Golem. Golem impressed me with its real world application of 3d rendering using popular free real world modelers people actually use. It will destroy render farms, but coudl also obsolete all crypto mining with its power, oops.
Thats interesting, was not aware of Golem. Will be researching this one.
I myself , have IOP and OMG. They seem as solid projects with good potential.
