The simplest usage of average without an article would be “let’s average FB’s data” (where average is a used as a verb). That’s completely acceptable to say in normal usage but maps to “let’s blockchain FB’s data” which you’d presumably hate. We could also say “I used an average”/“I used a blockchain” (average being a gerund/noun form of a verb as in “I went for a run”) or we could say “I computed the average”/“I forked the blockchain” (akin to “on my run”, where we are referring to a specific instance or result of the verb to average or to run).
