comment Fairness in cryptography
By fair, do you mean "cheat proof", where user A might transfer his last bit but not get the final bit in return from user B? Can you edit the question to clarify it?

comment How many bits of entropy would I get from 300 coin tosses?
@user21767, "fair coin" refers to a coin that has an even chance of turning up heads or tails, one that shows no bias over multiple flips. It encompasses the entire process of flipping a coin, including rotations, speed, wind, gravity, whatever; and it is considered fair only if the outcome is statistically unpredictable.
