Oracles solutions for blockchain (Summary)

[repl]

In search of all possible solutions for problem of how to supply data from extrernal world into blockchain world,
I haven't found any decent, mature methodology or best practice, neither have I found any good real life examples.
Offcourse there are such services as http://www.oraclize.it/#services, NEM with API for his NIS,
and tons of other projects about which I do not even guess.

So my intentions to aggregate collaborative knowledge and experience about this topic in one place
It will helps a lot those who do real projects.
