Hello @devann and @arthur.grafo
As pointed out by @arthur.grafo, reliable, as a word, is widely subjective and can mean different things to different. In my personal opinion, instead of trying to give subjective meaning to well-meaning arguments, using consensus as a base can help solve the debate.
A consensus based protocol that gives a weighted average consideration to all inputs and propagates outputs accordingly can certainly do the trick.
Thanks for the comments.
