Koinster thank you very much for quick answer!
Actually I tought it's something like that, then my statement where i said it's "best solution" stands? It's clear to me that it's not mathematical proof for "Theorem" Two Generals' Problem, but it is best that humans can make

Bitcoin is pretty nice way to prove people how humans have low level of mathematical knowlage, but also how powerfull impact math have on humankind perspective about world. It's showing us also that we are not even near to solutions of big mathematical problems that will also change human perspective when they become solved. Mostly I'm refering to P = NP.
For me, as a low level mathematitian and software developer,
it's completley wrong how we are approaching to Bitcoin. I see it just like some killer app on blockchain protocol. Other cryptocurrencies are just some other apps on blockchain protocol. It's like blockchain is some secure community (like internet was back in 1991, when people lack of knowlage of IP protocol), bitcoin is like browser for that protocol and other cryptocurrencies are just like some other regular web apps. Some of them stronger some of them weeaker.
Still if someone can confirm me my statement about P = NP I would be very happy.
Peace and love to everyone!
