consensus algorithmI nearly missed the whole round again. I'm just trying my luck with this one, I hope I'm right.
nice move and respect - i had a very hard time with this word

Thanks!

"Consensus" just kind of popped out in my head when I saw the letters, the rest was relatively easy because I just had to find a word that fits and that makes sense.
Round #4 is complete. Stay tuned for the next one!
Looking forward to it!
