Title: 50%-50% probablity calculation Post by: davidshrugged on February 23, 2013, 04:28:12 AM My first post ;D!!!!
We just released a flipping coin game for bitcoins [our twist: with chained flips] http://www.mangofuzz.com/ and we are using the following method to simulate the 50&-50% chance of tossing a coin. In C++ we :
If such number is less than 0.5, the user wins. We will use R instead of C in the next incarnation. Thoughts on this simple approach?

They generate a list of secret keys, one for each day, and publish the hashes ahead of time. They then use that secret to determine your random number, and they publish the plaintext secrets for previous days after the fact so that results can be verified.
