Blockchain domains seem to be growing in the cryptocurrency space and competing for mass adoption. In fact today a new extension was launched, .crypto. The .crypto extension joins .zil, .eth, and others. Currently the discussions for "Blockchain Domains" are mostly centered in the "gTLD" category of the "Domain Extensions" section. It is very important to note that Blockchain Domain extensions are NOT a gTLD as they do not resolve on the DNS or are regulated by ICANN. The attributes of blockchain domains and gTLD's are very different and should not rest together. I suggest creating an additional category named "Blockchain Extensions" under the "Domain Extensions" section.
