It's used by literally everyone on a daily basis and the most profitable companies on earth are using the technology without paying their dues. On top of all that. When SFOR gets the notoriety they have earned and deserved long ago their other products for securing your accounts will only explode into popularity and be further proven. This is completely ignoring the newer endeavors like Blocksafe...
So many possibilities.
Again just what I SEE and My opinion.
I am just willing to acknowledge reality. What is there is indeed there. No further proof is needed. The patents exist.
